In an aircraft maintenance program, discrepancies found must be documented by?

In an aircraft maintenance program, it is essential that any discrepancies found on the aircraft are documented by an appropriately rated mechanic. This is because maintenance and discrepancies need to be recorded by someone who holds the necessary certifications and knowledge to understand the technical issues and implications involved. An appropriately rated mechanic possesses the qualifications and training required to assess the condition of the aircraft, comprehend its maintenance requirements, and ensure that the documentation is completed accurately and in compliance with aviation regulations.

While a pilot in command may note or be aware of discrepancies during flight operations, they typically do not have the authority or expertise to document these issues for maintenance purposes. Similarly, air traffic controllers are responsible for managing air traffic rather than inspecting or maintaining aircraft. The aircraft manufacturer, while knowledgeable about the aircraft's specifications and design, usually does not engage in the day-to-day documentation of discrepancies during maintenance unless there are issues that require their specific input. Thus, the documentation by the appropriately rated mechanic is critical for proper maintenance and operational safety.
