REGULATORY TEXT:  
89-15-04 BOEING: Amendment 39-6250.
Applicability: Model 757-200 series airplanes through line number 164, equipped with Pratt and Whitney PW2000 engines, certificated in any category.
Compliance: Required within one year after the effective date of this AD, unless previously accomplished.

To prevent engine in-flight shutdown and engine damage, due to loss of engine oil resulting from cracked oil pressure indicator tube assemblies, accomplish the following:

A. Remove five oil pressure indication system tube assemblies and replace them with flexible hose assemblies, in accordance with Boeing Service Bulletin 757-79-0005, dated May 26, 1988.

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

NOTE: The request should be forwarded through an FAA Principal Maintenance Inspector (PMI), who will either concur or comment and then send it to the Manager, Seattle Aircraft Certification Office.

C. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base in order to comply with the requirements of this AD.

All persons affected by this directive who have not already received the appropriate service documents from the manufacturer may obtain copies upon request to Boeing Commercial Airplanes, P.O. Box 3707, Seattle, Washington 98124. These documents may be examined at the FAA, Northwest Mountain Region, Transport Airplane Directorate, 17900 Pacific Highway South, Seattle, Washington, or Seattle Aircraft Certification Office, 9010 East Marginal Way South, Seattle, Washington.

This amendment (39-6250, AD 89-15-04) becomes effective on July 24, 1989.
