Which of the following defects is a cause for rejection of wood propellers?

Dye penetrant inspection failure.
Bonding or separation of the trailing edge of the propeller blade.
Delamination found by conducting a tap test.
Light surface scratches.

The correct answer is: Bonding or separation of the trailing edge of the propeller blade.

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.
