For serviceable dimensional limits of an engine part, which publication should be consulted?

When determining the serviceable dimensional limits of an engine part, consulting the Current Engine Manufacturer's Overhaul Manual is essential. This manual provides specific guidelines, measurements, and tolerances required for the proper maintenance and overhaul of the engine components. It is the primary source that includes detailed information regarding the engineering and design of parts, ensuring that technicians can confirm if the components meet the required serviceability standards.

The other publications, while valuable, do not focus solely on the dimensional limits of engine parts. Type Certificate Data Sheets provide general information about the aircraft and its components but lack the in-depth detail found in the overhaul manual. Service Instruction Manuals may offer service tips and procedures but typically do not include comprehensive dimensional specifications. Aircraft Specifications Manuals generally provide overall specifications for the aircraft, rather than detailed information needed for engine part dimensions. Thus, for precise measurements and limits necessary for serviceable engine parts, the overhaul manual is the definitive reference.
