GCAA AME Licence Exam study guide
GCAA AME Licence Exam · Work through your exam, one topic at a time.
The GCAA Aircraft Maintenance Engineer (AME) Licence is the United Arab Emirates' credential for certifying aircraft maintenance, issued under the General Civil Aviation Authority's licensing framework and aligned with the Part-66 aircraft maintenance licence structure used in the region. It is aimed at technicians and engineers who inspect, repair, overhaul and return aircraft to service, and who need certifying privileges on the UAE register. The GCAA AME Licence Exam study guide has 9 sections and about 2,596 words.
01Aviation Legislation and Regulatory Framework
Civil aviation regulation follows a layered structure: international standards from ICAO (the Chicago Convention and its Annexes), national law that gives the regulator legal power, and the regulator's own regulations, advisory material and acceptable means of compliance. Under a GCAA-style system you should know the difference between a regulation (mandatory), an advisory circular or guidance material (not mandatory but an accepted way of showing compliance), and a standard adopted by reference.
286 words, about 1 min02Aircraft General Knowledge - Airframe, Systems and Structures
Start with structural philosophy: the difference between fail-safe (multiple load paths, crack-stopper straps, scheduled inspection) and safe-life (component retired before predicted failure), and damage tolerance as the modern extension of fail-safe. Know the primary, secondary and tertiary structure and why a question about a wing spar versus a fairing matters.
293 words, about 1 min03Aircraft General Knowledge - Electrical, Avionics and Instruments
For electrical systems: DC generation (starter-generators, alternators with rectifiers), parallel operation and load sharing, busbar architecture (essential/emergency bus, bus ties), battery types and their care, circuit protection (fuses, thermal and magnetic breakers), bonding and shielding, and the significance of a ground power unit connection sequence. Understand split-bus and why essential services are isolated.
291 words, about 1 min04Aircraft General Knowledge - Powerplant (Turbine and Piston Engines)
For turbine engines: the Brayton cycle in plain terms - intake, compression, combustion, exhaust - and how thrust is produced by momentum change. Know the compressor types (axial, centrifugal), the purpose of variable stator vanes and bleed valves to avoid surge, combustion chamber types, turbine blade cooling, and the accessory gearbox.
314 words, about 2 min05Maintenance Practices and Human Factors
Maintenance practice covers documentation and control: the task card, the work package, the certification of work, the maintenance release, and the handling of deferred defects and concessions. Know the rules for recording work - who signs, when, and what must be entered - and the meaning of a duplicate inspection and a critical task.
287 words, about 1 min06Basic Aerodynamics and Flight Mechanics
Begin with the four forces and their balance in steady flight. Understand how lift is generated - circulation and pressure distribution, not just Bernoulli - and the meaning of angle of attack, the critical angle, and the stall.
297 words, about 1 min07Mathematics, Physics and Electrical Fundamentals
Mathematics: arithmetic and algebra (transposition of formulas), ratios and percentages, geometry (areas, volumes, circumference, Pythagoras), trigonometry (sine, cosine, tangent and their use in resolving vectors), and graphs. Physics: units and conversions (SI and imperial), mass versus weight, density, pressure (absolute versus gauge), work, power, energy, and the gas laws.
266 words, about 1 min08Materials, Hardware and Corrosion Control
Know the common aircraft materials: aluminium alloys (2024, 7075 and their heat treatment), titanium, steel and stainless steel, magnesium, and composites (fibre and resin, lay-up, and the meaning of a delamination or a disbond). Understand the properties that matter: strength, stiffness, fatigue resistance, corrosion resistance, and thermal expansion.
286 words, about 1 min09Airworthiness, Inspection and Quality Assurance
Airworthiness is a continuing state, not a one-off certificate. Know the difference between initial airworthiness (type certificate, certificate of airworthiness issue) and continuing airworthiness (maintenance programme, airworthiness directives, service bulletins, repairs and modifications, and the airworthiness review).
