REGULATORY TEXT:  
88-07-02 BOEING: Amendment 39-5885. Applies to all Model 767 series airplanes and to those Model 757 series airplanes equipped with Rolls-Royce RB211 engines, certificated in any category.

Compliance required within the next 2,000 hours time-in-service or 1 year after the effective date of this AD, whichever occurs first, unless previously accomplished.

To minimize the potential for inadvertent engine shutdown when using the electronic engine control (EEC) or engine limiter control (ELC) switches, accomplish the following:

A. Relocate the electronic engine control switches or engine limiter control switches, as applicable, from the control stand to the overhead panel in a manner approved by the Manager, Seattle Aircraft Certification Office, FAA, Northwest Mountain Region.

B. The fuel control switch guard installation made in compliance with AD T87-13- 51, Amendment 39-5718, may be removed following accomplishment of paragraph A., above.

C. An alternate means of compliance or adjustment of the compliance time, which provides an acceptable level of safety and which has the concurrence of an FAA Principal Maintenance Inspector, may be used when approved by the Manager, Seattle Aircraft Certification Office, FAA, Northwest Mountain Region.

D. Special flight permits may be issued in accordance with FAR 21.197 and FAR 21.199 to operate airplanes to a base for the accomplishment of the modification required by this AD.

This amendment supersedes AD 87-13-51, Amendment 39-5718 (52 FR 33917; September 9, 1987).

This amendment becomes effective May 11, 1988.
