Storage
General (installed engine).
Proper steps must be taken, on engines used infrequently, to lessen the possibility of
corrosion. This is especially true if the aircraft is based near the sea coast or in areas of high
humidity.
In all geographical areas the best method of preventing corrosion of internal parts of the
engine is to fly the aircraft at least once a week. Alternatively the engine should be run long
enough to reach normal operating temperatures.
9.5.1
Storage up to 90 Days
No special treatment is required for storage periods of up to 90 days.
The aircraft should be protected from the weather and excessively damp conditions.
9.5.2
Storage beyond 90 Days
The following procedures may require that the engine is
removed from the aircraft – see aircraft manufacturer’s
instructions.
Never rotate the engine with the oil can nozzle still in the
spark plug or exhaust / inlet ports!
1)
To protect the internal of the engine it is recommended that additional engine oil be
introduced. This can, for example, be via the spark plug holes, the throttle body or
the exhaust and is determined by the aircraft manufacturer.
2)
Where appropriate, ensure all electrical circuits are off, and then manually rotate the
propeller shaft and engine.
3)
Inject 5cc of the prescribed engine lubrication oil through either spark plug hole in the
rotor housing. (See CAUTION! above)
4)
Rotate the engine through 1 revolution of the flywheel (by turning the propeller or
propeller shaft and hence the eccentric shaft, by hand).
5)
Repeat (3 & 4) five times.
6)
Rotate the engine through 6 revolutions of the flywheel then refit the spark plugs.
7)
Seal all inlets and exhaust openings to prevent moisture ingress.
