A. Installed Engine Preservation Instructions (Six Months or Less)
WARNING
: MOST PRESERVATIVE SOLUTIONS ARE FLAMMABLE AND
SHOULD NOT BE USED EXCESSIVELY NOR APPLIED TO A
HOT ENGINE. ALLOW ENGINE TO COOL FOR A MINIMUM OF
10 MINUTES BEFORE USING PRESERVATIVE MATERIAL ON
ANY PART OF THE ENGINE.
(1) Allow engine to cool.
(2) Inspect engine to assure that inlet area is clean and dry.
CAUTION
: AIRCRAFT INLET AND TAILPIPE PLUGS FOR ENGINE SHALL
BE INSTALLED PRIOR TO WASHING THE AIRCRAFT OR IF
AIRCRAFT IS TO BE PARKED UNSHELTERED WHEN NOT IN
SERVICE. TO MINIMIZE OR PREVENT CORROSION, WATER
OR CLEANING SOLUTION SHALL NOT BE PERMITTED TO
ENTER THE ENGINE INLET AREA.
(3) Install inlet and tailpipe plugs.

CAUTION
: DO NOT EXCEED MANUFACTURER’S RECOMMENDED DUTY
CYCLE FOR STARTER.
2. A. (4) Every four weeks, with inlet and tailpipe plugs removed, motor engine with starter
sufficiently to achieve N1 rotation, observing manufacturers recommended duty cycle
for starter.
(5) Repeat Steps (2) and (3).
(6) It is recommended that digital electronic engine control (DEEC) (76-10-02) be placed in
air-tight bag containing desiccant for storage.
B. Installed Engine Preservation Instructions (More Than Six Months)
CAUTION
: THE COMPRESSOR SECTION SHALL NOT BE SPRAYED WITH
ANY CORROSION-PREVENTIVE COMPOUND. NO HYDROCARBONS OR OILS, INCLUDING DE-ICING/ANTI-ICE FLUID
SHALL EVER BE SPRAYED INTO INLET, EXHAUST, SCOOPS,
VENTS, AND DRAINS DURING ENGINE OPERATION. UNCONTROLLED COMBUSTION COULD BE A POSSIBLE RESULT.
AVOID OPERATING ENGINE DURING AIRCRAFT DE-ICING.
(1) Disconnect fuel control discharge line between oil temperature regulator (fuel/oil cooler)
and fuel control and connect a line to the fuel control discharge port to drain overboard.
(2) Disconnect fuel supply line at inlet connection on fuel pump and connect supply of oil.
Supply oil under two to five pounds per square inch pressure.
CAUTION
: DO NOT EXCEED MANUFACTURER’S RECOMMENDED DUTY
CYCLE FOR STARTER-GENERATOR.
(3) De-energize ignition system. Advance power lever to idle position. Motor fuel control
until clean oil flows from overboard drain line. Fuel control may be motored by motoring engine, observing motoring procedures established by the particular installation.
(4) Stop motoring engine, disconnect oil supply lines from fuel inlet port on fuel pump and
cap inlet port. Allow residual oil to drain from fuel control and lines, then disconnect
overboard drain line and reconnect fuel line between fuel control and fuel/oil cooler.
NOTE
: Use of corrosion-preventive compound in the engine lubrication sys-
tem for preservation is not required. Specified engine lubricating oil is
a satisfactory corrosion preventive.
(5) Wipe all fuel and oil from engine. Secure warning tags to engine and as required to
indicate preservation procedures have been performed and that engine shall not be
operated except as noted until depreservation procedures are performed. Maintain
engine motoring record indicating engine shall be motored every four weeks.
(6) Install inlet and tailpipe plugs.

CAUTION
: TO PREVENT LOSS OF PRESERVATION OIL FROM FUEL CON-
TROL, DO NOT OPEN FUEL SHUTOFF VALVE OR MOVE
THROTTLE WHILE MOTORING ENGINE.
2. B. (7) Every four weeks motor engine with starter sufficiently to obtain N1 rotation, observing
starter manufacturers recommended duty cycle. Ensure fuel shutoff valve is in cut-off
position.
(8) It is recommended that digital electronic engine control (76-10-02) be placed in air-tight
bag containing desiccant for storage.
C. Engine Preservation Instructions (Engine Removed from Aircraft)
CAUTION
: THE COMPRESSOR SECTION SHALL NOT BE SPRAYED WITH
ANY CORROSION-PREVENTIVE COMPOUND. NO HYDROCARBONS OR OILS, INCLUDING DE-ICING/ANTI-ICE FLUID
SHALL EVER BE SPRAYED INTO INLET, EXHAUST, SCOOPS,
VENTS, AND DRAINS DURING ENGINE OPERATION. UNCONTROLLED COMBUSTION COULD BE A POSSIBLE RESULT.
AVOID OPERATING ENGINE DURING AIRCRAFT DE-ICING.
(1) Prior to removing engine from aircraft perform fuel control preservation procedures as
outlined in Steps
B.(1) through B.(5).
(2) Drain engine lubricating oil observing procedures in Oil Servicing.
(3) Remove engine from aircraft and install inlet and tailpipe plugs.
(4) Wrap engine in barrier material (MIL-PRF-121) and seal all openings to prevent en-
trance of foreign material.
(5) Install engine into barrier material (MIL-PRF-131, Type I, Class III) with four bags of
desiccant and two humidity indicator cards. Install humidity indicator plug into barrier
material (MIL-PRF-131, Type I, Class III). Seal barrier material (MIL-PRF-131, Type I,
Class III) seam using sealer.
(6) Cut opening into barrier material (MIL-PRF-131, Type I, Class III) and insert vacuum
line. Evacuate air from barrier material (MIL-PRF-131, Type I, Class III) until barrier
material (MIL-PRF-131, Type I, Class III) is drawn snugly to engine. Remove vacuum
line and seal opening in barrier material (MIL-PRF-131, Type I, Class III) using heat
gun.
(7) Record preservation in Engine Log Book.
(8) Check humidity indicator plug and humidity indicator cards every 30 days. If indicator
plug or card changes from blue to pink, bag must be opened and engine inspected for
rust or corrosion. If rust or corrosion is evident, take appropriate corrective action.
Preserve engine in accordance with Steps
(4) through (8) after inspection completed.
