What is a likely consequence of ignoring small propeller damage?

• A. Minor cosmetic damage.
• B. The aircraft will automatically correct the issue.
• C. Fuel efficiency improves.
• D. Catastrophic damage to the aircraft due to propeller failure.

Answer: (D)

Small propeller damage acts as a crack starter on a part that spins at high speed and undergoes variable loads. Those nicks or flaws create stress concentrations, so with each revolution the crack can grow due to fatigue. As the crack advances, a blade can fail or separate, producing a violent imbalance, loss of thrust, and potential damage to the engine nacelle and surrounding structure. Ignoring such damage thus risks a catastrophic propeller failure, which is why this is the most likely and serious consequence. The other options aren’t correct because damage isn’t merely cosmetic, there’s no automatic correction mechanism, and damage typically reduces efficiency rather than improving it.
