TEO-540-C1A Engine Maintenance Manual
CAUTION
DAMAGE TO A PROPELLER IS SERIOUS AND CAN CAUSE THE
ENGINE TO BE UNAIRWORTHY.
(a)
Circumstances of a propeller strike cannot always be used as predictors of the extent
of engine damage or its future reliability. There can be varying degrees of damage to
an engine and propeller from a propeller strike. The initial damage can be hidden but
could become progressively worse with time and wear.
(b)
Given these possibilities and the fact that there is no identified clear, quantifiable
threshold limit or gradient standard to reliably measure the extent of damage to an
engine, Lycoming Engines can only recommend BEFORE FURTHER FLIGHT, that
you complete the tasks in the sequential order shown in the Engine Inspection
Checklist After Propeller Strike for TEO-540-C1A Engines (in this chapter) as
corrective action for a propeller strike. Make a copy of the checklist and complete it.
NOTICE:
The agency that returns the aircraft to service is responsible for the decision
to operate an engine that had a propeller strike. Lycoming Engines does not
take responsibility for the decision to return the engine to service after a
propeller strike. Refer to the latest revision of Service Bulletin No. SB-533.
