REGULATORY TEXT:  
89-07-17 MCDONNELL DOUGLAS: Amendment 39-6169.

Applicability: Model DC-9 series, Model DC-9-80 series, Model MD-88, and C-9 (military) series airplanes, certificated in any category.

Compliance: Required as indicated, unless previously accomplished.

To detect center tank fuel pump failures, accomplish the following:

A. Within 10 calendar days after the effective date of this AD, revise the Limitations Section of the FAA-approved Airplane Flight Manual (AFM) to add the following, and provide to flight crews. This may be accomplished by inserting a copy of this AD in the AFM:

SECTION I - LIMITATIONS

FUEL MANAGEMENT

Add the following wording at the beginning of this section: "Prior to engine start on any flight where center tank fuel is present and will be needed for that route segment, the center tank fuel pumps must be individually checked to verify pump operation. This must be accomplished by observing that both inlet fuel pressure low lights extinguish when each individual center tank pump is activated.

NOTE: Center tank pumps on aircraft with a center tank fuel pump low pressure warning system installed are not required to be checked in accordance with these procedures."

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, Los Angeles Aircraft Certification Office, FAA, Northwest Mountain Region.

NOTE: The request should be forwarded through an FAA Principal Operations Inspector (POI), who may add any comments and then send it to the Manager, Los Angeles Aircraft Certification Office.

This amendment (39-6169, AD 89-07-17) becomes effective on May 4, 1989.
