LIGHT MAINTENANCE MANUAL

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

CAUTION: ALLOW THE ENGINE TO COOL APPROXIMATELY ONE HOUR

OR UNTIL ITT INDICATOR READS 100°C OR LESS.

NOTE: Caution should be exercised during cold weather (below 0°C (32°F)) since equipment has no provisions to prevent freezing.

2.F. (4) Perform compressor rinse procedure.

CAUTION: REFER TO AIRCRAFT MAINTENANCE MANUAL FOR

STARTER DUTY CYCLE. DO NOT EXCEED STARTER

DUTY CYCLE AT ANY TIME DURING CLEANING PROCE-

DURE.

TO ELIMINATE BATTERY DISCHARGE DUE TO STARTER

MOTORING CYCLES, IT IS RECOMMENDED THAT A

GROUND POWER UNIT BE UTILIZED DURING THESE

OPERATIONS.

(a)Verify that ITT indicator reads 100°C or less.

(b)Verify that all bleed systems are closed and that power lever is in cut-off position.

NOTE: Ensure that power lever is in cut-off position (no fuel) and ignition system is turned off throughout rinse cycles.

If spray mix applicator nozzle is not properly angled, fan rotor assembly will centrifuge fluid. (See Figure 302.)

(c)Energize starter and motor engine in accordance with Aircraft Maintenance Manual. As engine high pressure spool starts to rotate, direct nozzle of spray mix applicator as close as possible to base of fan rotor assembly blades at an angle that is parallel to blade airfoil contour and blade base contour and open water control valve on spray mix applicator to inject fresh water. Motor engine to a minimum speed of ten percent N2 indication for 45 seconds or starter duty cycle limit, whichever is less.

De-energize starter and continue to inject fresh water until engine rolls down then shut off water control valve on spray mix applicator. Success of fresh water inducement is noted by water being discharged from exhaust nozzle.

(d)Allow starter to cool in accordance with Aircraft Maintenance Manual. Allow engine to drain induced water.
