Light Maintenance Manual

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

2.F. (5) Restore engine to operational status.

(a)Remove protective cover (or tape) from inlet pressure and temperature sensor and starter/generator.

(b)Reverse blow compressed air (approximately 50 psig) through disconnected P3 tubes removed from fuel control P3 pressure limiter valve fitting.

(c)Remove cap, previously installed, from fuel control P3 pressure limiter valve fitting. Connect P3 tube to fuel control P3 pressure limiter valve fitting. (See Figure 301.)

(6)Perform dry-out procedure of engine immediately following compressor rinse and resto- ration of engine to operational status.

WARNING: AREAS IN PROXIMITY OF ENGINE INLET AND EXHAUST ARE EXTREMELY HAZARDOUS TO PERSONNEL WHEN ENGINES ARE OPERATING. PERSONNEL SHALL CLEAR THESE AREAS DURING ENGINE START AND OPERA- TION TO AVOID INJURY.

NOTE: Refer to Aircraft Maintenance Manual for any special instructions relative to dry-out procedure.

(a)Perform normal engine start in accordance with Aircraft Flight Manual and/or appropriate aircraft document.

(b)[5-1J]Operate engine at idle speed for approximately 10 minutes, then advance power to 80 percent N1 speed indication. Turn on anti-ice air. When ITT indica- tion rises, turn off anti-ice air.

(c)[5A, 5-1H]Operate engine at idle speed for approximately 10 minutes.

(d)Perform normal engine shutdown in accordance with Aircraft Flight Manual and/or appropriate aircraft document.
