What does AMM stand for and why is it used?

• A. Aircraft Maintenance Manual; provides official procedures, specifications, and limits for maintenance tasks.
• B. Auto Maintenance Manual; used for car repairs.
• C. Airframe Manual of Measures; used for weight calculations.
• D. Aircraft Maintenance Memorandum; used for memos.

Answer: (A)

AMM stands for Aircraft Maintenance Manual. It is the official reference that tells technicians exactly how to perform maintenance tasks, and it includes the approved procedures, specifications, and limits for the aircraft. This manual ensures work is done consistently and safely by providing step-by-step instructions, torque values, tolerances, inspection intervals, and safety precautions. Other options don’t reflect aviation practice: they refer to non-aviation contexts or unofficial memos, whereas the AMM is the certified source used to maintain airworthiness and guide repairs and inspections.
