REGULATORY TEXT:  
84-10-04 BOEING: Amendment 39-4872. Applies to Model 737 series airplanes certificated in all categories listed in Boeing Service Bulletin 737-24-1038 dated May 13, 1983, or later FAA approved revisions. To insure continued structural integrity of the elevator control system and to minimize a potential fire hazard, accomplish the following within the next 300 landings or 30 days, whichever occurs first, after the effective date of this AD, unless accomplished since the last removal of the APU generator circuit breaker:

A. Inspect the APU feeder cable on the aft side of Body Station 259.5 for interference with control cables as specified in Boeing Service Bulletin 737-24-1038 dated May 13, 1983, or later FAA approved revisions.

B. Repair or replace any severed or damaged cables before further flight and insure that APU feeder cable attachments are intact. Relieve any cable interference in accordance with accepted methods prescribed by FAA Advisory Circular AC 43.13-1A, Chapter 11, Section 7, or in accordance with the modification specified by paragraph D., below.

C. Repeat the inspection of paragraph A., above, following each removal of the APU generator circuit breaker, until the modification specified in paragraph D., below, is accomplished.

D. The inspections required by paragraph A. may be terminated by installation of the modification specified in Boeing Service Bulletin 737-24-1038 dated May 13, 1983, or later FAA approved revisions.

E. For purposes of complying with this AD, subject to acceptance by the assigned FAA Principal Maintenance Inspector, the number of landings may be determined by dividing each airplane's hours time in service by the operator's fleet average from takeoff to landing for the airplane type.

F. Airplanes may be flown to a maintenance base for repairs or replacement in accordance with FAR 21.197 and 21.199 with prior approval of the Manager, Seattle Aircraft Certification Office, FAA, Northwest Mountain Region.

G. Alternate means of compliance which provide an equivalent level of safety may be used when approved by the Manager, Seattle 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 Boeing Commercial Airplane Company, P.O. Box 3707, Seattle, Washington 98124. These documents may also be examined at the FAA, Northwest Mountain Region, 9010 East Marginal Way South, Seattle, Washington.

This amendment becomes effective June 4, 1984.
