McDonnell Douglas DC-9-82 (MD-82) and DC-9-83 (MD-83) Airplanes; and Model MD-88 Airplanes
Model DC-9-82 (MD-82) and DC-9-83 (MD-83) airplanes, and Model MD-88 airplanes; as listed in Boeing Alert Service Bulletin MD80-25A367, Revision 01, dated June 14, 2002; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas DC-9-82 (MD-82) and DC-9-83 (MD-83) airplanes; and Model MD-88 airplanes, that requires inspection of the captain's and first officer's seat track locking pins for insufficient engagement caused by seat track misalignment, and corrective actions if necessary. This action is necessary to prevent uncommanded movement of the captain's and first officer's seats during takeoff and landing, which could result in interference with the operation of the airplane and consequent temporary loss of control of the airplane. This action is intended to address the identified unsafe condition.
To prevent uncommanded movement of the captain's and first officer's seats during takeoff and landing, which could result in interference with the operation of the airplane and consequent temporary loss of control of the airplane, accomplish the following:
(a) Within 6 months after the effective date of this AD, perform a detailed inspection of the captain's and first officer's seat track locking pins for sufficient engagement, and any applicable corrective actions by accomplishing all the actions in the Accomplishment Instructions of Boeing Alert Service Bulletin MD80-25A367, Revision 01, dated June 14, 2002. Do the actions per the service bulletin. Any applicable corrective actions must be accomplished before further flight.
Note 1: For the purposes of this AD, a detailed inspection is defined as: “An intensive visual examination of a specific structural area, system, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at intensity deemed appropriate by the inspector. Inspection aids such as mirror, magnifying lenses, etc., may be used. Surface cleaning and elaborate access procedures may be required.”
(b) Any inspection/corrective action accomplished before the effective date of this AD per Boeing Alert Service Bulletin MD80-25A367, dated December 6, 1999, is considered acceptable for compliance with the corresponding inspection/corrective action specified in this AD.
(c) In accordance with 14 CFR 39.19, the Manager, Los Angeles Aircraft Certification Office, FAA, is authorized to approve alternative methods of compliance for this AD.
(d) Unless otherwise specified in this AD, the actions shall be done in accordance with Boeing Alert Service Bulletin MD80-25A367, Revision 01, dated June 14, 2002.
