Light Maintenance Manual

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

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 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)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.
