Step-by-step instructions
Stop and secure the engine
Disconnect ignition or otherwise prevent accidental starting using the manufacturer guidance before approaching the propeller.
Look for blade damage
Check accessible blades for chips, bends, severe corrosion or cracks without removing hardware in unsafe conditions.
Check for line entanglement
Fishing line behind the propeller can damage shaft seals and should be addressed using the proper service procedure.
Record changes underway
Note new vibration, reduced speed or unusual engine loading after a suspected strike.
Arrange service
Have a mechanic assess propeller repair, shaft alignment and gearcase seals when an impact is suspected.
Safety note
Never touch a propeller with the ignition enabled or engine operating. Sharp blades and sudden motion can cause severe injury.
Key takeaway
Small propeller damage can cause vibration and later seal problems.
