Which instruction outlines the reporting procedures for activities with reportable engines?

The correct choice outlines the reporting procedures specific to activities involving reportable engines. NA 13700.15 is designed to provide clear guidelines and protocols that personnel responsible for these engines must follow. This ensures compliance with regulatory requirements and facilitates proper documentation and reporting of engine activities, which is critical for maintenance operations and safety management.

In comparison, the other options do not pertain specifically to reporting procedures for activities involving engines. Each of them may address different topics or functions within the maintenance or production control scope, but NA 13700.15 is uniquely focused on the requirements relevant to reportable engines, making it the appropriate reference for such procedures.
