Question 1Aircraft Maintenance Engineering (B1.3) - licence category knowledge

In a gas turbine engine, what is the primary function of the diffuser section of the compressor outlet?

  1. To cool the air before it enters the combustion chamber
  2. To raise the static pressure of the air while reducing its velocity Correct answer.
  3. To increase the air velocity before combustion
  4. To add fuel to the air stream

Explanation

The diffuser converts the high velocity of the compressor discharge air into static pressure by gradually expanding the flow area, so the air enters the combustion chamber at a lower speed and higher pressure. This pressure rise improves combustion stability and efficiency. Cooling or fuel addition are functions of other sections.

Question 2Aircraft Maintenance Engineering (B1.3) - licence category knowledge

Which document normally states the maintenance tasks and intervals that must be accomplished for an aircraft to remain within its approved maintenance programme?

  1. The aircraft flight manual
  2. The type certificate data sheet
  3. The weight and balance report
  4. The maintenance programme approved by the competent authority Correct answer.

Explanation

The approved maintenance programme defines the scheduled tasks, intervals and procedures that keep the aircraft airworthy. It is approved by the competent authority and forms the basis for planning maintenance. The flight manual and type certificate data sheet contain operating limits and certification data, not maintenance intervals.

Question 3Aircraft Maintenance Engineering (B1.3) - licence category knowledge

On an aircraft hydraulic system, what is the purpose of an accumulator?

  1. To cool the hydraulic fluid during operation
  2. To measure the flow rate of the pump
  3. To store pressurised fluid and damp pressure surges Correct answer.
  4. To filter particulate contamination from the fluid

Explanation

An accumulator contains a gas-charged chamber separated from the hydraulic fluid, allowing it to store energy, smooth pressure pulsations and supply a limited quantity of fluid if the pump fails. It does not filter, cool or measure flow. These are separate components.

Question 4Aircraft Maintenance Engineering (B1.3) - licence category knowledge

What is the effect of increasing the blade tip clearance on a turbine stage?

  1. Higher efficiency because leakage reduces blade loading
  2. Higher efficiency because the gas flow is more uniform
  3. No effect on efficiency but higher vibration
  4. Lower efficiency because gas leaks past the tips without doing work Correct answer.

Explanation

Gas that passes over the tips of the turbine blades without flowing through the aerofoil does no useful work on the rotor. Excessive tip clearance therefore reduces turbine efficiency and increases specific fuel consumption. Efficiency is not improved by leakage.

Question 5Aircraft Maintenance Engineering (B1.3) - licence category knowledge

Which inspection method is best suited to detecting surface-breaking cracks in a non-magnetic aluminium alloy component?

  1. Magnetic particle inspection
  2. Eddy current testing of ferromagnetic parts
  3. Magnetic flux leakage
  4. Dye penetrant inspection Correct answer.

Explanation

Dye penetrant inspection relies on capillary action to draw a visible dye out of surface-breaking defects and works on non-porous materials regardless of magnetic properties, so it suits aluminium. Magnetic methods require ferromagnetic material. Eddy current is not restricted to ferromagnetic parts, but the option given is incorrect.

Question 6Aircraft Maintenance Engineering (B1.3) - licence category knowledge

What is the main purpose of a torque wrench calibration check in an approved maintenance organisation?

  1. To verify the colour coding of the socket set
  2. To confirm that the tool delivers the indicated torque within permitted limits Correct answer.
  3. To increase the maximum torque capability of the tool
  4. To convert the tool for use with different fastener sizes

Explanation

Calibration confirms that the torque indicated by the tool corresponds to the actual applied torque within an acceptable tolerance. This protects fasteners and joints from under- or over-torquing. Calibration does not change the tool's capability or convert it for other uses.

Question 7Aircraft Maintenance Engineering (B1.3) - licence category knowledge

In the context of aircraft electrical systems, what does the term 'bonding' refer to?

  1. Connecting the battery to the charger
  2. Providing a low-resistance electrical path between structural parts Correct answer.
  3. Securing cables with cable ties
  4. Insulating the airframe from lightning

Explanation

Bonding establishes a controlled low-resistance connection between metallic parts so that fault currents and lightning currents have a defined path. It also helps control static electricity and provides a return path for electrical systems. It is not a mechanical fastening or insulation technique.

Question 8Aircraft Maintenance Engineering (B1.3) - licence category knowledge

Which of the following is a correct statement about the classification of maintenance tasks under the MSG-3 methodology?

  1. All tasks are classified as either hard-time or on-condition
  2. Tasks are developed from failure modes and their consequences Correct answer.
  3. Only lubrication tasks are considered in MSG-3 analysis
  4. MSG-3 applies only to engines and not to structures

Explanation

MSG-3 analysis starts from the functions of the item, identifies failure modes and evaluates the consequences of each failure to select appropriate tasks. This produces a scheduled maintenance programme tailored to the system, structure or powerplant. It is not limited to lubrication or to engines.

Question 9Aircraft Maintenance Engineering (B1.3) - licence category knowledge

A reciprocating engine is running and the oil pressure gauge reads zero. Which action is the most appropriate initial response?

  1. Ignore the gauge because it may be a false reading
  2. Shut down the engine and investigate the indication Correct answer.
  3. Increase power to raise oil pressure
  4. Continue running to see whether the pressure recovers

Explanation

Zero oil pressure while running indicates a possible loss of lubrication that can rapidly cause catastrophic engine damage. The safe response is to shut down and investigate, including verifying whether the indication is genuine. Continuing operation or increasing power risks seizure.

Question 10Aircraft Maintenance Engineering (B1.3) - licence category knowledge

During a compression test on a reciprocating engine cylinder, the pressure reading is low, but it rises when a small amount of oil is added to the cylinder. What does this most likely indicate?

  1. A blocked fuel injector
  2. A leaking intake valve
  3. An incorrect magneto timing
  4. Worn piston rings or cylinder bore Correct answer.

Explanation

Oil temporarily seals the gap between the piston rings and the cylinder wall, so a pressure rise after adding oil points to ring or bore wear. Leaking valves usually do not improve much with oil because the leak path is at the valve seat. Ignition timing and fuel injection do not affect a compression test in this way.

Question 11Aircraft Maintenance Engineering (B1.3) - licence category knowledge

An aircraft is equipped with a constant-speed propeller. What is the function of the propeller governor?

  1. To cool the propeller blades
  2. To limit the maximum manifold pressure
  3. To maintain the selected engine speed by varying blade pitch Correct answer.
  4. To control the fuel flow to the engine

Explanation

The governor senses engine speed and adjusts oil pressure to the propeller hub to change blade angle, thereby holding the selected rpm as load or airspeed changes. Fuel flow and manifold pressure are controlled by the fuel control unit and the throttle. Blade cooling is not a governor function.

Question 12Aircraft Maintenance Engineering (B1.3) - licence category knowledge

Why is a specific torque sequence used when tightening the cylinder head bolts of a reciprocating engine?

  1. To ensure the bolts can be removed more easily later
  2. To distribute clamping load evenly and avoid distortion Correct answer.
  3. To allow the use of a smaller torque wrench
  4. To reduce the total time required for assembly

Explanation

Tightening in a defined sequence and in stages distributes the clamping force evenly around the joint, preventing warping of the cylinder head and uneven gasket loading. This improves sealing and reduces the risk of cracking. Time saving or tool size are not the reasons.

Question 13Aircraft Maintenance Engineering (B1.3) - licence category knowledge

Aircraft electrical cables are routed with a certain minimum bend radius. What is the main reason for this requirement?

  1. To make the cable easier to label
  2. To prevent damage to the conductor and insulation from excessive bending Correct answer.
  3. To reduce the weight of the loom
  4. To improve the appearance of the installation

Explanation

Bending a cable too sharply can crack the insulation, fatigue the conductor strands and alter the electrical characteristics of the cable. Respecting a minimum bend radius protects the cable's mechanical and electrical integrity. Weight, labelling and appearance are not the governing reasons.

Question 14Aircraft Maintenance Engineering (B1.3) - licence category knowledge

What is the purpose of a shear wire or shear nut in an aircraft control system?

  1. To provide a controlled failure point that protects the structure Correct answer.
  2. To measure the tension in the control cable
  3. To lock the control cable against all movement
  4. To carry the full flight load of the control surface

Explanation

A shear element is designed to fail at a predetermined load so that a jam or overload does not transmit damaging forces into the surrounding structure. It acts as a sacrificial protection device. It is not intended to carry normal flight loads or to lock the system.

Question 15Aircraft Maintenance Engineering (B1.3) - licence category knowledge

During a borescope inspection of a turbine engine, a small nick is found on the leading edge of a compressor blade. Which factor is most important in deciding whether the blade is serviceable?

  1. The number of blades in the stage
  2. The colour of the blade coating
  3. The ambient temperature at the time of inspection
  4. The location and size of the damage compared with the limits in the maintenance manual Correct answer.

Explanation

Serviceability of a damaged blade is judged against the damage limits published in the engine maintenance manual, taking into account the size, depth and location of the defect. The manual defines what may be blended out or must be replaced. Colour, blade count and ambient temperature are not the deciding criteria.

Question 16Aircraft Maintenance Engineering (B1.3) - licence category knowledge

What is the main difference between a 'hard-time' task and an 'on-condition' task?

  1. Hard-time tasks are performed only after a failure occurs
  2. Hard-time tasks apply only to avionics
  3. On-condition tasks are always performed at every flight
  4. Hard-time tasks have a fixed interval, while on-condition tasks depend on measured condition Correct answer.

Explanation

A hard-time task requires removal or overhaul at a fixed interval regardless of condition, whereas an on-condition task is performed when a measured parameter or inspection indicates the need. On-condition work relies on condition monitoring and defined limits. Neither category is restricted to avionics or performed every flight.

Question 17Aircraft Maintenance Engineering (B1.3) - licence category knowledge

Why must an aircraft be weighed and its centre of gravity checked after a major modification?

  1. Because the modification changes the colour scheme
  2. Because weighing is required after every flight
  3. Because the modification may change the empty weight and the centre of gravity position Correct answer.
  4. Because the fuel tanks must be emptied for all maintenance

Explanation

A major modification can add or remove mass and shift the centre of gravity, which affects performance, stability and structural loads. Weighing verifies that the aircraft remains within its approved weight and balance envelope. Colour, routine flight operations and fuel handling are not the reason.

Question 18Aircraft Maintenance Engineering (B1.3) - licence category knowledge

A crack is found in a structural member of an aircraft. Under what circumstances may the aircraft be returned to service without repair?

  1. Whenever the crack is shorter than 10 mm
  2. Only if the crack is painted over
  3. Never, because any crack requires scrapping of the aircraft
  4. Only when the crack is within the limits permitted by the approved structural repair manual or an approved concession Correct answer.

Explanation

Structural damage must be assessed against the approved data, such as the structural repair manual or a concession approved by the competent authority. If the damage falls within the permitted limits, the aircraft may be returned to service. Arbitrary dimensions or cosmetic treatment are not acceptable.

Question 19Aircraft Maintenance Engineering (B1.3) - licence category knowledge

What is the function of a fuel-oil heat exchanger in a turbine engine installation?

  1. To warm the fuel and cool the oil using the other fluid Correct answer.
  2. To separate water from the fuel
  3. To increase the fuel pressure to the injectors
  4. To filter the oil before it reaches the bearings

Explanation

A fuel-oil heat exchanger transfers heat between the fuel and the oil, warming the fuel to prevent ice formation and cooling the oil to keep it within limits. It does not pressurise fuel, separate water or filter oil. Those functions belong to other components.

Question 20Aircraft Maintenance Engineering (B1.3) - licence category knowledge

An aircraft battery is found to be serviceable but has a low state of charge. Which action is appropriate before returning it to service?

  1. Replace the battery immediately regardless of condition
  2. Add distilled water until the cells overflow
  3. Charge it in accordance with the manufacturer's instructions and check the electrolyte Correct answer.
  4. Discharge it fully to reset the cells

Explanation

A low battery should be recharged following the manufacturer's procedures, and the electrolyte level and specific gravity should be checked to confirm condition. Overfilling, unnecessary replacement or deliberate deep discharge can damage the battery or waste resources.

Question 21Aircraft Maintenance Engineering (B1.3) - licence category knowledge

In a turbine engine, what is the purpose of the bleed valves on the compressor?

  1. To prevent compressor surge at low speeds by discharging some air Correct answer.
  2. To release excess fuel from the combustion chamber
  3. To supply air to the cabin only
  4. To increase the compressor pressure ratio at high power

Explanation

At low engine speeds the rear compressor stages may not be able to accept the airflow from the front stages, risking surge or stall. Bleed valves open to discharge some air and match the flow, improving stability during acceleration. They are not fuel valves and do not raise the pressure ratio.

Question 22Aircraft Maintenance Engineering (B1.3) - licence category knowledge

A fan blade in a high-bypass turbofan is found to have a minor impact mark. Which consideration is most relevant to determining whether the blade may remain in service?

  1. The colour of the paint on the fan cowl
  2. The number of flight hours since the last wash
  3. The blade's part number only
  4. The size, depth and location of the damage relative to the engine manual limits Correct answer.

Explanation

Fan blade damage is assessed against the limits in the engine maintenance manual, which specify allowable nicks, dents and blend-out criteria according to size, depth and position. Part number alone, cosmetic details or wash intervals do not determine serviceability.

Question 23Aircraft Maintenance Engineering (B1.3) - licence category knowledge

Why is a hot section inspection (HSI) of a turbine engine performed at defined intervals?

  1. To measure the fuel tank quantity
  2. To adjust the propeller pitch
  3. To check the external paint finish
  4. To assess wear, cracking and distress in components exposed to high temperature Correct answer.

Explanation

Hot section components such as turbine blades, nozzles and combustion liners operate at extreme temperatures and are subject to creep, cracking and oxidation. Periodic inspection detects deterioration before it becomes a hazard. Paint, propeller pitch and fuel quantity are unrelated.

Question 24Aircraft Maintenance Engineering (B1.3) - licence category knowledge

In an aircraft electrical power system, what is the purpose of a current limiter in a feeder circuit?

  1. To increase the voltage supplied to the busbar
  2. To protect the circuit from excessive current by opening at a defined value Correct answer.
  3. To convert alternating current to direct current
  4. To store electrical energy for later use

Explanation

A current limiter is a protective device that opens the circuit when current exceeds a defined value for a sufficient time, protecting cables and equipment from overheating. It does not change voltage, rectify current or store energy.

Question 25Aircraft Maintenance Engineering (B1.3) - licence category knowledge

What is the significance of the 'fail-safe' design concept in aircraft structures?

  1. The structure is designed to never require inspection
  2. The structure is designed to operate without any maintenance
  3. The structure is designed to be lighter than any other structure
  4. The structure is designed so that failure of one element does not cause loss of the structure Correct answer.

Explanation

Fail-safe design ensures that if a single element or load path fails, alternate paths can carry the load until the failure is detected at inspection. This concept relies on scheduled inspections to find damage before it becomes critical. It does not eliminate inspection or maintenance.

Question 26Aircraft Maintenance Engineering (B1.3) - licence category knowledge

Under EASA Part-66, which category of licence permits the holder to issue certificates of release to service after line maintenance on turbine-powered helicopters?

  1. B2
  2. B1.3 Correct answer.
  3. B1.2
  4. B1.1

Explanation

The B1.3 licence category covers turbine-powered helicopters, allowing the holder to certify line maintenance and release to service after such work. B1.1 covers turbine-powered aeroplanes, B1.2 covers piston-engine helicopters, and B2 covers avionics systems. Each category is defined by the type of aircraft and the systems the holder is qualified to maintain.

Question 27Aircraft Maintenance Engineering (B1.3) - licence category knowledge

Which document must be completed and signed before an aircraft is returned to service after a scheduled maintenance check?

  1. Certificate of Release to Service (CRS) Correct answer.
  2. Maintenance programme
  3. Technical log
  4. Airworthiness Review Certificate

Explanation

A Certificate of Release to Service (CRS) is the formal declaration that the maintenance work has been completed satisfactorily and the aircraft is airworthy. It must be signed by an authorised certifying staff member. The maintenance programme defines what work is to be done, the technical log records defects and operations, and the Airworthiness Review Certificate is a separate periodic airworthiness validation.

Question 28Aircraft Maintenance Engineering (B1.3) - licence category knowledge

What is the primary purpose of the duplicate inspection requirement for flight control systems after assembly or adjustment?

  1. To verify that the correct part numbers have been installed
  2. To ensure that all fasteners are torqued to the specified value
  3. To confirm that the system operates freely and correctly before flight Correct answer.
  4. To check that the control surfaces move in the correct direction

Explanation

A duplicate inspection requires two independent qualified persons to check the flight control system after assembly or adjustment. Its main purpose is to confirm that the system is correctly connected and operates freely and correctly through its full range of movement before flight. This independent verification reduces the risk of an error that could lead to loss of control.

Question 29Aircraft Maintenance Engineering (B1.3) - licence category knowledge

In the context of aircraft maintenance, what does the term 'airworthiness directive' (AD) require?

  1. Action to be taken to correct an unsafe condition on an aircraft Correct answer.
  2. A voluntary modification to enhance aircraft performance
  3. A recommendation for improved maintenance practices
  4. A routine inspection to be performed at the next scheduled check

Explanation

An airworthiness directive is a mandatory instruction issued by the airworthiness authority to correct an unsafe condition that could affect the safety of an aircraft. It specifies the required actions, such as inspections, modifications, or operational limitations, and the compliance time. ADs are legally binding and must be complied with to maintain the aircraft's airworthiness.

Question 30Aircraft Maintenance Engineering (B1.3) - licence category knowledge

When performing a maintenance task on an aircraft, what is the purpose of using a torque wrench with a calibrated setting?

  1. To apply a specified force to a fastener to ensure proper clamping without overstressing Correct answer.
  2. To measure the length of a fastener before installation
  3. To check the hardness of a fastener material
  4. To determine the thread pitch of a fastener

Explanation

A torque wrench is used to apply a specific amount of torque to a fastener, which creates the correct clamping force to hold components together securely. Over-torquing can damage threads or the component, while under-torquing can lead to loosening. The calibrated setting ensures the specified torque is accurately applied.

Question 31Aircraft Maintenance Engineering (B1.3) - licence category knowledge

What is the primary function of a hydraulic accumulator in an aircraft hydraulic system?

  1. To filter contaminants from the hydraulic fluid
  2. To cool the hydraulic fluid during operation
  3. To store hydraulic fluid under pressure and dampen pressure fluctuations Correct answer.
  4. To increase the flow rate of the hydraulic pump

Explanation

A hydraulic accumulator stores hydraulic fluid under pressure, typically using a compressed gas or spring, to provide a reserve of power and to dampen pressure surges in the system. It helps maintain system pressure during peak demands and compensates for small leaks. It does not filter, cool, or increase pump flow.

Question 32Aircraft Maintenance Engineering (B1.3) - licence category knowledge

In aircraft maintenance, what does the term 'on-condition maintenance' mean?

  1. Maintenance performed based on the observed condition of an item Correct answer.
  2. Maintenance performed before each flight
  3. Maintenance performed at fixed intervals regardless of condition
  4. Maintenance performed only after a failure occurs

Explanation

On-condition maintenance involves inspecting or testing an item to determine its condition and then deciding whether maintenance is needed. It is a preventive approach that relies on condition monitoring rather than fixed time intervals. This allows maintenance to be performed only when the condition indicates it is necessary.

Question 33Aircraft Maintenance Engineering (B1.3) - licence category knowledge

What is the purpose of a magnetic particle inspection (MPI) in aircraft maintenance?

  1. To identify the alloy composition of a component
  2. To measure the thickness of a material
  3. To check the electrical conductivity of a material
  4. To detect surface and near-surface defects in ferromagnetic materials Correct answer.

Explanation

Magnetic particle inspection is a non-destructive testing method used to detect surface and near-surface discontinuities in ferromagnetic materials. The component is magnetised and iron particles are applied; they accumulate at defects, revealing cracks or flaws. It is not used for thickness measurement, alloy identification, or conductivity testing.

Question 34Aircraft Maintenance Engineering (B1.3) - licence category knowledge

Which of the following is a correct statement about the use of lockwire in aircraft maintenance?

  1. Lockwire is used to secure fasteners against loosening due to vibration Correct answer.
  2. Lockwire is used to provide electrical bonding between components
  3. Lockwire is used to measure the torque applied to a fastener
  4. Lockwire is used to indicate the direction of fluid flow

Explanation

Lockwire, also known as safety wire, is installed through holes in fastener heads and twisted to prevent them from rotating and loosening under vibration. It is a positive locking method required in many critical applications. It does not measure torque, provide bonding, or indicate flow direction.

Question 35Aircraft Maintenance Engineering (B1.3) - licence category knowledge

What is the primary consideration when selecting a replacement component for an aircraft system?

  1. The component must be manufactured in the same country as the aircraft
  2. The component must have the lowest cost available
  3. The component must be approved for the specific aircraft type and system Correct answer.
  4. The component must be the lightest weight option

Explanation

When replacing a component, it is essential to ensure that the replacement part is approved for the specific aircraft type and system. This means it must meet the applicable airworthiness requirements and be listed in the approved parts catalogue or have appropriate approval. Cost, weight, and country of manufacture are secondary to airworthiness and conformity.

Question 36Aircraft Maintenance Engineering (B1.3) - licence category knowledge

In the context of aircraft maintenance, what is the purpose of a 'functional check' after a system repair?

  1. To ensure that all tools have been removed from the aircraft
  2. To confirm that the repair was performed within the allocated time
  3. To document the cost of the repair
  4. To verify that the system operates correctly within specified limits Correct answer.

Explanation

A functional check is performed after a repair or modification to confirm that the system or component operates correctly and within the specified limits. It typically involves operating the system through its full range and observing parameters. It does not check time, tool control, or cost.

Question 37Aircraft Maintenance Engineering (B1.3) - licence category knowledge

What is the primary purpose of the aircraft weighing procedure?

  1. To check the structural integrity of the landing gear
  2. To verify the maximum take-off weight
  3. To determine the empty weight and centre of gravity for loading calculations Correct answer.
  4. To measure the fuel capacity of the aircraft

Explanation

Weighing an aircraft determines its empty weight and the position of its centre of gravity (CG). These values are used to calculate the safe loading of the aircraft for flight, ensuring that the CG remains within limits. It is not a structural check, fuel capacity measurement, or direct verification of maximum take-off weight.

Question 38Aircraft Maintenance Engineering (B1.3) - licence category knowledge

In a turbine engine ignition system, what is the purpose of the exciter unit?

  1. It monitors exhaust gas temperature and trims the fuel schedule
  2. It converts low-voltage DC supply into high-voltage pulses delivered to the igniter plugs Correct answer.
  3. It controls the opening of the starter air valve during cranking
  4. It regulates the fuel flow to the combustor during engine start

Explanation

The exciter is the component that takes the low-voltage aircraft DC supply and stores or transforms energy to produce the high-voltage, high-energy discharge needed to spark the igniter plug, particularly for relight at altitude. It does not govern fuel or starting airflow; those functions belong to the fuel control unit and the start control system.

Question 39Aircraft Maintenance Engineering (B1.3) - licence category knowledge

A cable tension check on a primary flight control run shows the tension is below the rigging tolerance given in the maintenance manual for the current temperature. What is the most appropriate action?

  1. Defer the check to the next C-check since the aircraft is flyable
  2. Adjust the turnbuckles to bring tension within the temperature-corrected tolerance and record the result Correct answer.
  3. Reduce tension further to avoid overloading the pulleys
  4. Leave it as is because cable tension naturally rises in service

Explanation

Control cable tension varies with temperature, so the maintenance manual provides a rigging chart that relates ambient temperature to acceptable tension. The correct action is to compare the measured value with the chart for the actual temperature and, if outside limits, adjust the turnbuckles and record the rigging in the technical log. Simply ignoring the reading or deferring it leaves the control system incorrectly rigged.

Question 40Aircraft Maintenance Engineering (B1.3) - licence category knowledge

An aircraft with a fixed-pitch propeller is reported to have a lower than normal static RPM at full throttle on the ground. Which combination of factors is most likely to explain this?

  1. A propeller blade angle that is too coarse for the engine speed
  2. Excessive propeller tip clearance in the cowling
  3. An over-rich mixture at high altitude cruise settings
  4. Reduced engine power output or an incorrectly set propeller blade angle Correct answer.

Explanation

Static RPM on the ground with a fixed-pitch propeller is set by the balance between engine power available and the power absorbed by the propeller at that blade angle. A low static RPM therefore points either to the engine not developing rated power (ignition timing, mixture, compression, induction restriction) or to a propeller whose blade angle is too coarse, absorbing more power than intended. Both must be investigated against the type data.

Question 41Civil Aviation Act 2017 and CAR 84 (Civil Aviation Regulations)

Under the Civil Aviation Act 2017, which authority is responsible for administering the Act and making civil aviation rules in New Zealand?

  1. The Civil Aviation Authority of New Zealand Correct answer.
  2. The Transport Accident Investigation Commission
  3. The Ministry of Transport
  4. Airways New Zealand

Explanation

The Civil Aviation Act 2017 establishes the Civil Aviation Authority as the regulator that administers the Act and issues civil aviation rules. The Authority's functions include safety oversight, rule-making and certification of aviation participants. Other bodies have different statutory roles and do not administer the Act.

Question 42Civil Aviation Act 2017 and CAR 84 (Civil Aviation Regulations)

What is the primary purpose of the Civil Aviation Act 2017?

  1. To regulate airport retail concessions
  2. To establish a safe and secure civil aviation system Correct answer.
  3. To set airline ticket pricing policy
  4. To manage immigration at airports

Explanation

The Act's stated purpose is to establish and maintain a safe and secure civil aviation system in New Zealand. It achieves this through regulatory functions, safety oversight and the making of civil aviation rules. Matters such as ticket pricing or retail concessions fall outside its safety purpose.

Question 43Civil Aviation Act 2017 and CAR 84 (Civil Aviation Regulations)

Under the Civil Aviation Act 2017, who holds ultimate responsibility for the airworthiness of an aircraft operated under a maintenance organisation's control?

  1. The licensed aircraft maintenance engineer only
  2. The operator or owner of the aircraft Correct answer.
  3. The fuel supplier
  4. The maintenance organisation's receptionist

Explanation

The Act and rules place the primary responsibility for continued airworthiness on the operator or owner of the aircraft. Approved maintenance organisations and licensed engineers carry out and certify work, but responsibility for the aircraft remains with the operator. This principle underpins all maintenance planning requirements.

Question 44Civil Aviation Act 2017 and CAR 84 (Civil Aviation Regulations)

A person performs maintenance on a New Zealand-registered aircraft without holding the required licence or authorisation. Under the Civil Aviation Act 2017, this conduct is best described as:

  1. An offence against the Act Correct answer.
  2. A matter for the insurer only
  3. A minor administrative error
  4. Permissible if the owner consents

Explanation

The Act creates offences for performing licensed aviation activities without the required licence or authorisation. Owner consent does not override the statutory licensing requirement. Such conduct can lead to prosecution and significant penalties.

Question 45Civil Aviation Act 2017 and CAR 84 (Civil Aviation Regulations)

Which document issued under the civil aviation rules prescribes the specific maintenance requirements for a particular aircraft type?

  1. The air operator certificate
  2. The maintenance programme approved for that aircraft Correct answer.
  3. The pilot's logbook
  4. The aircraft's registration certificate

Explanation

An approved maintenance programme sets out the scheduled maintenance tasks and intervals applicable to a specific aircraft or operator. The registration certificate evidences nationality and registration only. Pilots' logbooks and air operator certificates serve different purposes.

Question 46Civil Aviation Act 2017 and CAR 84 (Civil Aviation Regulations)

Under CAR 84, who may certify the release to service of an aircraft after maintenance?

  1. Any member of the flight crew
  2. The aircraft owner without training
  3. An appropriately licensed or authorised person Correct answer.
  4. A passenger with mechanical knowledge

Explanation

Release to service must be certified by a person holding the appropriate licence or authorisation for the work performed. This ensures competence and accountability for the maintenance carried out. Flight crew, owners and passengers cannot certify maintenance unless separately authorised.

Question 47Civil Aviation Act 2017 and CAR 84 (Civil Aviation Regulations)

What must an engineer do when they discover a defect that affects the safety of flight during maintenance?

  1. Note it informally in a personal diary
  2. Record and rectify the defect before release to service Correct answer.
  3. Defer it to the next scheduled check
  4. Report it only to the next shift

Explanation

Any defect affecting safety of flight must be recorded and rectified, or otherwise properly controlled, before the aircraft is released to service. Deferral is permitted only where the rules and maintenance programme allow it with appropriate controls. Informal notes do not satisfy the recording requirement.

Question 48Civil Aviation Act 2017 and CAR 84 (Civil Aviation Regulations)

Which of the following best describes the role of the Civil Aviation Rules (CARs) made under the Act?

  1. They prescribe detailed operational and technical requirements Correct answer.
  2. They replace the Act entirely
  3. They apply only to international airlines
  4. They are advisory guidance with no legal force

Explanation

The Civil Aviation Rules are delegated legislation made under the Act that set detailed technical and operational requirements. They have legal force and complement the broad principles in the Act. They do not replace the Act and apply broadly across aviation participants.

Question 49Civil Aviation Act 2017 and CAR 84 (Civil Aviation Regulations)

An engineer signs a maintenance record for a task that was not actually performed. Which statement best reflects the regulatory position?

  1. This is a false certification and may constitute an offence Correct answer.
  2. It is permitted if the engineer is supervised
  3. It is only a problem if an accident occurs
