8-1 GENERAL
There is no practical procedure that will insure corrosion prevention on installed aircraft
engines. Susceptibility to corrosion is influenced by geographical location, season and
usage. The owner/operator is responsible to recognize the conditions that are conducive to
corrosion and take appropriate precautions.
8-2 ENGINE PRESERVATION
Corrosive attack can occur in engines that are flown only occasionally regardless of
geographical location. In coastal areas and areas of high humidity corrosive attack can
occur in as little as two days. The best method of reducing the likelihood of corrosive attack
is to fly the aircraft at least once every week for a minimum of one hour.
NOTE. . . Corrosive attack may reduce engine service life. Of primary concern are cylinders,
piston rings, valves, valve guides camshaft and lifters.
NOTE. . . See Precision Airmotive Corporation instructions for preservation of the fuel servo
unit.
The following procedure, if properly utilized, will aid in reducing the severity of corrosive
attack.
8-3 TEMPORARY STORAGE
Preparation for storage.
1. Remove oil sump drain plug and drain oil. Replace drain plug, torque and safety.
Remove oil filter. Install new oil filter torque and safety. Service engine to proper sump
capacity with oil conforming to MIL-C6529 Type II.
2. Perform a ground run-up. Perform a pre-flight inspection and correct any discrepancies.
Fly the aircraft for one hour at normal operation temperatures.
WARNING
To prevent possibility of serious bodily injury or death, before moving the propeller
accomplish the following:
a. Disconnect all spark plug leads.
b. Verify magneto switches are connected to magnetos, that they are in the
"OFF" Position and "P" leads are grounded.
c. Throttle position "CLOSED."
d. Mixture control "IDLE-CUT-OFF."
e. Set brakes and block aircraft wheels.
f. Insure that aircraft tie-downs are installed and verify that the cabin door latch
is open.
g. Do not stand within the arc of the propeller blades while turning the propeller.
3. After flight remove all spark plug leads and remove the top spark plugs. Protect the
ignition lead ends with AN-4060 Protectors. Using a common garden sprayer or
equivalent, spray atomized preservative oil that - meets MIL-P-46002, Grade 1, at room
temperature through upper spark plug hole of each cylinder with the piston at bottom
dead center position. Rotate crankshaft as opposite cylinders are sprayed. Stop
crankshaft with none of the pistons at top dead center.
4. Re-spray each cylinder. To thoroughly cover all surfaces of the cylinder interior move
the nozzle or spray gun from the top to the bottom of the cylinder.
5. Install top spark plugs but do not install spark plug leads.
