Light Maintenance Manual

TFE731-5/-5AR/-5R (ATA NUMBER 72-02-75)

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 HYDRO- CARBONS OR OILS, INCLUDING DE-ICING/ANTI-ICE FLUID SHALL EVER BE SPRAYED INTO INLET, EXHAUST, SCOOPS, VENTS, AND DRAINS DURING ENGINE OPERATION. UNCON- TROLLED 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 motor- ing 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.
