REGULATORY TEXT:  
82-21-01 MCDONNELL DOUGLAS: Amendment 39-4471. Applies to McDonnell Douglas Model DC-9-80 series airplanes, Fuselage Number 924 through 1011, 1013 through 1022, 1025 through 1035, 1043 through 1055, and 1061, certificated in all categories.

Compliance required as indicated unless previously accomplished. To prevent failure of the throttle push-pull control cable, accomplish the following:

A. Within 300 hours after the effective date of this AD, perform a one-time pull check of the throttle push-pull control cable on both engines in accordance with McDonnell Douglas DC-9 Super 80 Alert Service Bulletin A76-38 dated July 22, 1982, Revision 1 dated July 27, 1982, or later revisions approved by the Manager, Los Angeles Area Aircraft Certification Office, FAA Northwest Mountain Region.

B. If the force is above the service bulletin limits and/or the push-pull control does not move smoothly, determine cause for roughness or binding and repair accordingly. If cause is isolated to cable blade element replace the throttle control cable assembly with a serviceable item.

CAUTION: USE EXTREME CARE WHEN WORKING WITH ENGINE PUSH-PULL CABLES. DO NOT BEND CABLE IN RADIUS SMALLER THAN 7-INCHES (18CM) MINIMUM OR DAMAGE TO CABLE WILL RESULT.

NOTE: Cable has a flat internal sliding ribbon and will bend in one direction only.

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.

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

NOTE: One alternate means of compliance is specified in Pacific Southwest Airlines (PSA) Engineering Specification DC-9-76-1 dated May 14, 1982, or Revision A, dated May 25, 1982.

The manufacturer's specifications and procedures identified and described in this directive are incorporated herein and made a part hereof pursuant to 5 U.S.C. 552(a)(1).

All persons affected by this directive who have not already received these documents from the manufacturer may obtain copies upon request to McDonnell Douglas Corporation, 3855 Lakewood Boulevard, Long Beach, California 90846, Attention: Director, Publications and Training, C1-750 (54-60). These documents also may be examined at FAA Northwest Mountain Region, 17900 Pacific Highway South, C-68966, Seattle, Washington 98168, or Los Angeles Area Aircraft Certification Office, 4344 Donald Douglas Drive, Long Beach, California 90808.
