Applicability: Model 737-100, -200, and -200C series airplanes, as listed in Section 4 and Appendices A.4 and B.4 of Boeing Document D6-38505, "Aging Airplane Service Bulletin Structural Modification and Inspection Program," Revision F, dated April 23, 1992; certificated in any category.

Compliance: Required as indicated, unless accomplished previously.

To prevent degradation of the structural capability of the airplane, accomplish the following:

(a) Accomplish the inspections specified in Section 4 and Appendices A.4 and B.4 of Boeing Document D6-38505, "Aging Airplane Service Bulletin Structural Modification and Inspection Program," Revision F, dated April 23, 1992, within the times specified in paragraph (b) of this AD, and thereafter at intervals not to exceed those specified in the Boeing Document for each inspection.

(b) The maximum initial inspection times for the inspections contained in Section 4 and Appendices A.4 and B.4 of Boeing Document D6-38505, "Aging Airplane Service Bulletin Structural Modification and Inspection Program," Revision F, dated April 23, 1992, shall be the later of the times specified in either paragraph (b)(1) or (b)(2) of this AD:

(1) The threshold for inspection time for the inspection specified in the Boeing Document, measured as a total (flight cycles, time-in-service, as appropriate) accumulated on the airplane; or

(2) The phase-in period for the inspection specified in the Boeing Document, measured from a date 15 months after the effective date of this AD.

NOTE: The "phase-in period," for the purposes of this AD, is defined as the allowable period to accomplish the initial inspection when the required threshold specified in paragraph (b)(1) of this AD is imminent or has elapsed.

(c) If any of the discrepant conditions identified in the service bulletins are found as a result of the inspections required by this AD, the corresponding corrective action specified in the service bulletins must be accomplished prior to further flight.

(d) The terminating action for each inspection required by paragraph (a) of this AD consists of the accomplishment of the modification specified in the corresponding service bulletin.

(e) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, Seattle Aircraft Certification Office (ACO), FAA, Transport Airplane Directorate. Operators shall submit their requests through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, Seattle ACO.

NOTE: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Seattle ACO.

(f) Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate the airplane to a location where the requirements of this AD can be accomplished.

(g) The inspections shall be done in accordance with Boeing Document No. D6- 38505, "Aging Airplane Service Bulletin Structural Modification and Inspection Program," Revision F, dated April 23, 1992, which contains the following list of effective pages:
