Unscheduled Inspection And Maintenance - Superior Vantage Engine O-360 SERIES Maintenance Manual

UNSCHEDULED INSPECTION AND MAINTENANCE

One-time unscheduled inspections as dictated by
unexpected damage from Propeller/Rotor Strike,
Foreign Object Damage (FOD), Overspeed,
Overboost, Lightning Strike, Contaminated Fuel,
Detonation, and Water Immersion are described
below.
•
Propeller/Rotor Strike
A prop/rotor strike may result in engine damage
and requires complete engine disassembly and
inspection IAW the Overhaul Manual prior to
returning the engine back to service. In addition
to the inspections required in the overhaul
manual, inspect all engine accessories IAW
manufacturer's instructions.
may result in catastrophic engine failure. Further
operation of an engine
propeller/rotor strike incident without inspection
is the responsibility of the authority returning the
engine to service. A propeller/rotor strike is
defined as:
−
Any incident, whether the engine is
operating or not, for which repair of the
propeller or rotor requires removal (see
FOD below).
−
Any incident during engine operation in
which contact of the propeller or rotor
with any object results in the loss of
engine RPM. This includes objects such
as the ground, water, grass, sand, stone,
etc., even if the propeller or rotor
continues to rotate.
•
FOD
Foreign object damage is defined as damage to
the propeller or rotor from small objects (such as
a small stone) during operation of the engine.
FOD repair must be accomplished IAW the prop
or rotor manufacturer's instructions.
damage requiring removal of the prop or rotor for
repair is considered a prop/rotor strike and the
engine must be inspected as described in the
previous section.

Overspeed
Operation of an engine in excess of 105% rated
RPM for more than 10 seconds, or 110% rated
RPM for any time, can cause serious damage.
Engines that have experienced overspeed must
be assessed for excessive loading damage by
complete engine disassembly and inspection
IAW the Overhaul Manual prior to returning the
engine back to service. Specific attention should
be paid during inspection for damage to
cylinders, bearings,
reciprocating components.

future use. Failure to do so may result in
catastrophic engine failure. Further operation of
an engine that has experienced overspeed
without inspection is the responsibility of the
authority returning the engine to service.
•
Overboost
Operation of an engine in excess of 110% rated
manifold pressure for more than 10 seconds, or
120% rated manifold pressure for any time, can
cause serious damage.
experienced overboost must be assessed for
excessive temperature or loading damage by
