When servicing the Engine Lubrication System, one should refer to which source?

• A. Flight manual
• B. Technical manual
• C. Manufacturer's website
• D. Aviation maintenance log

Answer: (B)

The technical manual is the primary reference for servicing the Engine Lubrication System because it provides detailed instructions, specifications, and procedures that are specific to the aircraft and its components. This manual is designed to ensure that maintenance personnel have the most accurate and relevant information necessary to safely and effectively service the engine's lubrication system. It includes diagrams, troubleshooting tips, and the correct types of lubricants to use, among other information critical for proper maintenance.

While the flight manual focuses on operational aspects and pilot usage, it does not contain the detailed maintenance information contained in the technical manual. The manufacturer's website may offer supplementary information but is not typically as comprehensive as the technical manual on specific servicing procedures. The aviation maintenance log is used to document maintenance activities rather than serve as a reference source for servicing instructions. Therefore, for technical and procedural guidelines, the technical manual is the authoritative source to consult.
