Iran CAO Part-66 AMT Theory study guide
Iran CAO Part-66 AMT Theory · Work through your exam, one topic at a time.
The Iran CAO Part-66 Aircraft Maintenance Engineer Licence theory examination is the basic-knowledge assessment a candidate must pass before applying for an aircraft maintenance licence issued by the Civil Aviation Organization of Iran (CAO.IRI). It is aimed at people training to certify maintenance on aeroplanes or helicopters - typically students at an approved Part-147 maintenance training organisation, experienced mechanics seeking their first licence, or licence holders adding a category or type rating. The Iran CAO Part-66 AMT Theory study guide has 12 sections and about 3,739 words.
01Mathematics
CAO Part-66 mathematics is a tool module: arithmetic, algebra, geometry and trigonometry, and graphs. Expect unit conversions, ratio and percentage, transposition of formulas, areas and volumes, and right-triangle work rather than abstract theory.
312 words, about 2 min02Physics
Physics covers matter, mechanics, statics, kinetics, fluid dynamics, thermodynamics, light and sound. The exam favours applied mechanics: mass versus weight, moments, pressure, density, energy, and the gas laws in a maintenance context.
301 words, about 2 min03Electrical Fundamentals
Electrical fundamentals covers electron theory, static electricity, DC circuits, capacitance, magnetism, inductance, AC theory, resistors, transformers and filters. The exam expects confident use of Ohm's law, series and parallel networks, power, reactance and transformer ratios.
315 words, about 2 min04Electronic Fundamentals
Electronic fundamentals covers semiconductor theory, diodes, rectifiers, transistors, printed circuit boards and servomechanisms. The emphasis is on how components behave in aircraft circuits, not on deep device physics.
314 words, about 2 min05Digital Techniques / Electronic Instrument Systems
This module covers number systems, data conversion, logic circuits, computers, data buses, fibre optics, displays and electronic instrument systems such as EICAS/ECAM and integrated avionics. Expect binary/hex conversion, gate logic and bus architecture questions.
322 words, about 2 min06Materials and Hardware
Materials and hardware covers ferrous and non-ferrous metals, composites, corrosion, fasteners, pipes, springs, bearings, transmissions, control cables and electrical cables. Questions test selection, identification and correct installation rather than metallurgy for its own sake.
319 words, about 2 min07Maintenance Practices
Maintenance practices covers safety, workshop tools, engineering drawings, fits and clearances, torque, inspection, NDT, cleaning, bonding, rigging and release procedures. It tests whether you can work to approved data and record the result correctly.
303 words, about 2 min08Basic Aerodynamics
Basic aerodynamics covers the atmosphere, airflow, Bernoulli and Newton, aerofoils, lift and drag, stability, and flight controls. The exam tests relationships and definitions more than complex calculation.
306 words, about 2 min09Human Factors
Human factors covers human performance, error, safety culture, communication, teamwork, fatigue, stress, situational awareness and decision-making. The exam expects you to recognise error types and the defences that reduce them, not to blame individuals.
315 words, about 2 min10Aviation Legislation
Aviation legislation covers the regulatory chain from ICAO to Iran CAO national requirements, including Part-66 licences, Part-145 organisations, Part-M continuing airworthiness and Part-147 training. Expect privileges, categories, records, airworthiness directives and maintenance release questions.
329 words, about 2 min11Aeroplane Aerodynamics, Structures and Systems
This module covers airframe structures, flight controls, hydraulics, landing gear, pneumatics, air conditioning, pressurisation, fuel, electrical power, lights, oxygen, ice and rain protection, and water/waste. Questions link system purpose to component function and failure effect.
301 words, about 2 min12Helicopter Aerodynamics, Structures and Systems
Helicopter aerodynamics, structures and systems covers rotor theory, hovering, translational lift, autorotation, retreating-blade stall, tail-rotor function, transmissions, vibration and special handling hazards. Expect relationship questions and simple tip-speed calculations.
