During an annual inspection, which would you expect to find as a maintenance release?

In the context of an annual inspection, a maintenance release signifies that maintenance actions have been performed in accordance with regulatory standards and that the aircraft is deemed airworthy. Both activities mentioned in the choices involve significant maintenance work that could impact the aircraft's safety and overall airworthiness.

Straightening an aluminum propeller blade and repairing a propeller governor are each critical repairs mandated to maintain the aircraft's operational integrity. Propeller blades are critical components that directly affect aircraft performance, and any deformation could lead to imbalances or inefficiencies. Similarly, the propeller governor controls the pitch of the propeller blades, regulating engine RPM and ensuring proper thrust during flight. Any malfunction in this system could have severe implications for aircraft control and performance.

By indicating that both repairs would be included in the maintenance release, it reflects the thorough nature of the annual inspection, where all airworthy measures must be documented and certified before the aircraft is returned to service. Thus, both the straightening of the propeller blade and the repair of the propeller governor should be acknowledged as part of the maintenance release process during the annual inspection.
