Light Maintenance Manual

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

2.C. (9) Engines preserved as stated in Steps (4) through (7) shall be removed from preserva- tion storage every two years, serviced with oil and motored sufficiently to achieve N1 rotation. Ensure fuel control power lever is in cutoff position prior to motoring. Pre- serve engine in accordance with Steps (2) through (8) after motoring.

(10)Engines received from manufacturer have been preserved prior to shipment. Preserva- tion is good for two years. Inspection of preserved engines shall be as stated in Steps

(8) and (9).

(11)It is recommended that digital electronic engine control (76-10-02) be placed in air-tight bag containing desiccant for storage.

D.If Aircraft is Not Sheltered During Extreme Wet Conditions

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 OPERATION TO AVOID INJURY.

(1)Engine conditions permitting, perform normal engine start in accordance with Aircraft Flight Manual and/or appropriate aircraft document. Run engine at idle speed for ten minutes.

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

(3)Preserve engine in accordance with Paragraph 2.A.

E. If Aircraft is Operated in a Salt Atmosphere or On Air Strips Treated With Salt

NOTE: Refer to Paragraph 3.B. for additional recommended procedure.

(1)Wash engine externally as soon as possible with clean fresh water.

(2)Perform normal engine start in accordance with Aircraft Flight Manual and/or appropri- ate aircraft document. Run engine at idle speed for a minimum of ten minutes to re- move moisture and salt residue.

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