REGULATORY TEXT:  
85-09-03 LOCKHEED-CALIFORNIA COMPANY: Amendment 39-5056. Applies to Lockheed Model L-1011 series airplanes equipped with RB211-22B engines, certificated in all categories. Compliance required as indicated, unless previously accomplished.

To minimize the potential fire hazard in the event of fire damage to the engine fuel supply line from uncontained gearbox fires, accomplish the following:

A. Revise the FAA approved Airplane Flight Manual (AFM), LR-25925, within 15 calendar days after receipt of this airworthiness directive by incorporation of the emergency engine inflight shutdown procedure whenever there is a rapid decrease of engine oil quantity indication, as follows:

SECTION 2 - EMERGENCIES

Rapidly Decreasing Engine Oil Quantity Indication.

If engine oil quantity indication decreases at an abnormally high rate requiring engine shutdown, assume a failure exists in the accessory gearbox and shutdown the engine as follows:

Throttle close
Fuel and ignition switch close
Fuel tank valve close

NOTE: If APU is required, and the No. 2 engine has been shutdown, pull circuit breakers 1L16 and 1L17 to protect hydraulic pump, then pull No. 2 engine fire handle, then open No. 2 tank valve. (If hydraulic quantity decreases, reset CB 1L16 and 1L17 to isolate hydraulic pump and stop fluid loss.)

B. A copy of this AD inserted in the AFM may be considered as an acceptable means of compliance.

C. Alternate means of compliance which provide an acceptable level of safety may be used when approved by the Manager, Los Angeles Aircraft Certification Office, FAA, Northwest Mountain Region.

All persons affected by this directive who have not already received these documents from the manufacturer may obtain copies upon request to Lockheed-California Company, P.O. Box 551, Burbank, California 91520, Attention: Commercial Support Contracts, Dept. 63-11, U-33, B-1. These documents may also be examined at the FAA, Northwest Mountain Region, 17900 Pacific Highway South, Seattle, Washington, or the Los Angeles Aircraft Certification Office, 4344 Donald Douglas Drive, Long Beach, California.

This amendment becomes effective May 20, 1985.
