b. Following loss of power during ground operation.
c. Following momentary engine shutdown.
d. During single engine operation for training purposes on twin engine aircraft.
3. Over priming and attempting engine start with the aircraft parked on an incline that
negates the effective operation of the drain system.
4. A failure to drain oil from cylinders that have been preserved.
Damage from a hydraulic lock can be extensive. Engine components such as connecting
rods, cylinder assemblies, pistons, piston pins, crankcase and crankshaft can be
damaged due to the extreme stress.
WARNING
Over priming can cause a flooded intake resulting in a "hydraulic lock" event and
subsequent engine malfunction or failure. If you over prime, or flood your engine,
make certain that all fuel has drained from the intake manifold and/or cylinder prior
to attempting engine starting.
INSPECTION PROCEDURES FOR SUSPECTED HYDRAULIC LOCK.
In the event of a suspected hydraulic lock, perform the following inspection:
1. Remove all cylinders and connecting rods in accordance with the applicable TCM
Overhaul Manual. Inspect the connecting rods in accordance with applicable TCM
Overhaul Manual.
2. If all rods meet the criteria specified by TCM, reassemble the engine in accordance
with the overhaul manual.
3. If any connecting rod does not meet TCM acceptance criteria, remove and
disassemble the engine to allow inspection of the crankcase and crankshaft in
accordance with the applicable TCM Overhaul Manual. Replace any part that does
not meet Overhaul Manual inspection criteria. Replace each non-conforming
connecting rod and its associated piston, piston pin and cylinder assembly.
NOTE: . . Any parts that require replacement must be destroyed to prevent future installation.
4. Reassemble the engine in accordance with the applicable TCM Overhaul Manual and
return the aircraft to service.
ENGINE OVERSPEED INSPECTION
Engine operation at speeds in excess of rated RPM limitations can cause damage to the
engine and can result in subsequent engine failure.
If an engine overspeed occurs determine the cause for overspeed and correct it. The
airframe manufacturer's instructions on engine and propeller overspeed must also be
referenced and followed.
If an engine overspeed occurs comply with the following procedures:
RPM TO 3000
1. Less than one minute - No action required
2. More than one minute - Proceed as follows:
a) Drain oil through a fine mesh screen and inspect for debris.
b) Remove oil filter and inspect filter element for debris.
