Engine mounts maintenance requirements are typically found in which manual?

• A. Aircraft Maintenance Manual.
• B. Engine Maintenance Manual.
• C. CMM for engine accessories.
• D. Type Certificate Data Sheet.

Answer: (A)

Engine mounts are part of the aircraft’s structure and how the engine is attached to the airframe. Maintenance requirements for those mounts—inspection intervals, torque specs, wear limits, and replacement criteria—are documented in the Aircraft Maintenance Manual, which covers airframe systems and engine installation details. The Engine Maintenance Manual focuses on the engine itself and its internal components, not the mounting to the airframe. The CMM for engine accessories deals with individual engine accessories, not the mounting hardware. The Type Certificate Data Sheet provides certification information, not maintenance procedures. So the Aircraft Maintenance Manual is the primary source for engine mount maintenance.
