For which scenario would you expect to find a maintenance release?

A maintenance release is a formal declaration by an authorized person that a specific maintenance task has been completed in accordance with applicable regulations and standards, and that the aircraft is airworthy. In both scenarios presented, either the straightening of steel blades or the repair of a propeller governor constitutes maintenance activities that affect the aircraft's safety and performance.

When steel blades, which are critical components in various systems like propellers or rotor blades, are straightened, it involves modification and potentially significant structural work that must meet established safety standards. The same applies to the repair of a propeller governor, as this component is essential for regulating the power output of the propeller; its malfunction or improper repair can severely affect aircraft performance.

Since both activities are subject to regulations requiring an inspection and a corresponding maintenance release to confirm completion, it is appropriate to expect a maintenance release for either action taken. The appropriate documentation reflects that the work has been carried out successfully and the aircraft maintains compliance with airworthiness standards. Therefore, it is reasonable to conclude that a maintenance release would be expected for either scenario presented.
