Iran CAO Part-66 AMT Theory study plan

Map the 28% aeroplane and 27% helicopter syllabi into a single checklist that separates shared content (flight controls, hydraulics, pneumatics, air conditioning, pressurisation, fuel, electrics, ice and rain protection, landing gear, oxygen, fire protection) from type-specific content

Explain in writing how a transport-category aeroplane generates and controls lift, drag, thrust and weight across takeoff, climb, cruise and approach, naming the primary and secondary flight controls involved

Describe the helicopter main rotor, tail rotor and swashplate control chain from cyclic, collective and pedals through to blade pitch change, and state how retreating-blade stall and dissymmetry of lift are managed

Sketch from memory the layout of a typical aeroplane hydraulic system and a typical helicopter hydraulic system, labelling reservoir, pump, accumulator, filter, selector valve and actuator

Trace the electrical power generation and distribution path on a twin-engine aeroplane from IDG or alternator through bus bars to essential loads, and compare it with a helicopter's generator and battery arrangement

Explain the operating principle and failure indications of the air conditioning and pressurisation system, including outflow valve, cabin pressure controller and the meaning of cabin altitude warnings

Describe fuel system components and sequencing for both categories, including boost pumps, crossfeed, venting, refuelling and defuelling and the consequences of a failed boost pump

Explain landing gear retraction, extension, locking and indication for an aeroplane and skid or wheel landing gear for a helicopter, including emergency extension means

Explain ice and rain protection for wings, engine intakes, pitot-static probes and windshields, and state the inspection points a line engineer checks before a flight in icing conditions

Describe fire detection and extinguishing for engines, APU and cargo compartments, including the difference between a detection loop fault and a genuine fire warning

Explain basic aerodynamics of the aeroplane in terms of boundary layer, stall, Mach effects and stability, and of the helicopter in terms of autorotation, ground effect and translational lift

Identify the structural assemblies of a semi-monocoque fuselage and a helicopter rotor blade and state the inspection methods used to find cracks and delamination

Classify aircraft materials by property and use, covering aluminium alloys, titanium, steel, composites, honeycomb and transparent plastics, and match each to a representative application

Identify standard hardware by sight and by designation, including AN, MS and NAS bolts, nuts, washers, rivets, turnlock fasteners, hoses, unions and control cables, and state the correct locking method for each

Apply torque, safetying and inspection practice to a described fastener installation, listing the sequence of checks from fit to final lockwire

Explain the precautions for composite and metal repair in terms of corrosion control, galvanic couple avoidance, sealing and allowable damage limits

Describe the documentation chain for a maintenance task from work order through inspection, certification and return to service, naming the roles of the certifying staff and the quality system

Explain the scope and structure of Part-66 licensing, Part-145 maintenance organisations and Part-M continuing airworthiness, and distinguish which tasks each framework governs

Interpret a maintenance release, certificate of release to service, logbook entry and airworthiness directive compliance record, and state what makes each one valid

Apply human factors and maintenance error models to a described incident, naming the error type, the contributing organisational factors and the defences that should have prevented it

Explain the purpose and limits of approved maintenance data, service bulletins, airworthiness directives and minimum equipment lists in dispatch decisions

Solve DC and AC circuit problems using Ohm's law, Kirchhoff's laws, series and parallel networks, power and impedance, and show working for each

Explain the construction and operating principle of transformers, generators, motors, relays and contactors, and interpret their typical in-service failure modes

Describe semiconductor devices including diodes, transistors, thyristors and operational amplifiers, and explain rectification, amplification and switching in aircraft circuits

Explain digital numbering systems, logic gates, data buses and the architecture of electronic instrument and indication systems, including EFIS, EICAS or ECAM and air data computers

Trace a fault through a described electrical or electronic system using a wiring diagram description and state the test points and expected readings

Solve arithmetic, algebra, geometry and trigonometry problems of the type used in aircraft maintenance, including percentage, ratio, area, volume and right-triangle calculations, without a calculator where possible

Explain mechanics, heat, light, sound and fluid behaviour as they appear in aircraft systems, including pressure, temperature, density and the gas laws

Apply human factors knowledge to shift work, fatigue, complacency, pressure, distraction and teamwork, and describe the individual and organisational countermeasures for each

Interpret the limitations of the human senses and memory in inspection tasks and describe the role of independent inspection and duplicate checks

Complete two full timed mock examinations under exam conditions and record the score per domain

Re-teach every domain where the mock score fell below 75 percent, using corrected notes rather than re-reading

Recite the regulatory framework for certification, maintenance release and continuing airworthiness from memory in a five-minute spoken summary

Explain the most commonly confused aeroplane and helicopter system differences without notes, including hydraulics, electrics, pressurisation and rotor or flight control
