AMP - Aviation Maintenance Technician Powerplant Practice Exam

Wood propellers are required to pass a rigorous inspection process to ensure safety and quality. Dye penetrant inspection failure, delamination found by conducting a tap test, and light surface scratches are all considered minor defects that can be repaired without causing significant issues with the propeller. However, bonding or separation of the trailing edge of the propeller blade is a major defect that can compromise the structural integrity and balance of the propeller. This defect can lead to catastrophic failure of the propeller in flight, making it a crucial factor in determining whether the propeller should be rejected or not.
