Propeller Strike / Sudden Stoppage Inspections
and Repairs
A propeller strike can cause unknown hidden damage to the engine or other components,
possibly leading to a catastrophic failure.
Your safety should be the first priority.
Whenever a propeller strike occurs, no matter how minor it appears, there are set
mandatory inspections in place by all propeller, engine and governor manufacturers to
determine the best course of action to follow for your safety, and to be in compliance
with Federal Aviation Regulations.
Some of the determining factors for the propeller, engine and governor course of
actions are:
Torn, bent or loss of blade tip
Excessive tip or radial play in blades
Vibration or sporadic operation
Loss or drop of RPM in engine
Any of these conditions are reasons for further inspections that include
tear-down or even overhaul of propeller, engine and governor.
Inspections for overspeed, overboost, hydraulic lock, fuel and oil contamination are
also available.
