CHECKS ON ENGINE & INSTALLATION
5.1
Daily Checks
Ensure free movement of throttle & choke cables.
Check Oil Level, replenish if necessary.
i)
Check oil level by screwing in cap fully before withdrawing
ii)
Oil level should be between the MAX & MIN marks - but must never be below
the MIN mark.
iii)
Before long periods of operation, ensure that the level is at least at the mid
position.
iv)
Difference in the oil quantity between MAX & MIN mark is 0.5 litres (0.528 US
Quarts).
v)
See section 13.1 for first 25 hours of Operation.
vi)
Overfilling is detrimental to the engine.
Check lubrication & fuel system for leaks.
i)
Visually inspect for signs of leakage on the ground where the aircraft was
parked overnight
ii)
Inspect the oil cooler for leaks through the cowl opening
iii)
Visually inspect the underside of the aircraft for fresh oil or fuel residue.
Check exhaust system for security.
i)
Wriggle the exhaust tail pipes by hand, checking for excessive movement,
rubbing on cowls or unusual noises.
With Ignition & Master OFF, and throttle closed, turn propeller by hand & observe
engine for odd noises or heavy movements. Check for regular compression. If
irregular, refer to Trouble Shooting section of this Manual for corrective action.
CAUTION:
Prior to pulling through the propeller by hand, both ignition circuits & the Master
Switch must be switched OFF, the brakes applied and the throttle closed.
WARNING
A hot engine may fire with the ignition/s switched OFF.
DO NOT TURN OVER A HOT ENGINE BY HAND
CAUTION:
A common cause of low compression is poorly sealing valves. Continued operation in this
condition will result in damage to valves, valve seats, valve guides & overhead gear.
Prior to takeoff - follow the Starting & Warm Up procedure, observe the engine
behavior & throttle response.
Check temperatures & pressures. Conduct a short ground test at full power (a few
seconds) (consult aircraft Flight Manual).
