Regarding the ability to perform minor straightening of steel propeller blades, which statement is true?

The correct answer indicates that neither statement regarding the ability to perform minor straightening of steel propeller blades is true. This is rooted in regulations and best practices surrounding aircraft maintenance.

In aviation maintenance, the authority to perform specific tasks, such as minor straightening of propeller blades, is generally restricted to qualified personnel or those with specific ratings. While some mechanics may have training that allows them to perform certain maintenance activities, minor straightening can fall under critical areas that require additional qualifications or adherence to the manufacturer's guidelines.

The common requirement is that only those with the appropriate level of training or certification, such as an airframe and powerplant (A&P) certificate, can perform work on propellers, and even then, it may be subject to further restrictions. These guidelines are in place to ensure safety and compliance with aviation standards and to preserve the integrity of the aircraft's components. Hence, stating that all mechanics or only powerplant rating holders are authorized is misleading, leading to the conclusion that neither statement can be deemed correct.
