Applicability: Model 737 series airplanes, as identified in Boeing Service Bulletin 737-25- 1231, dated July 7, 1988, certificated in any category.

Compliance: Required as indicated, unless previously accomplished.

To ensure structural integrity of the occupied flight attendant seat mounted on the aft right lavatory during flight and emergency landing conditions, accomplish the following:

A. Within 30 days after the effective date of this AD, remove the aft right lavatory- mounted attendant seat or install a placard on the aft right lavatory-mounted flight attendant seat, stating: "NO OCCUPANCY", or equivalent. This placard may be removed or the seat reinstalled once the terminating action of paragraph B., below, has been accomplished.

B. Within 6 months after the effective date of this AD, inspect the aft right lavatory partition beam for an inadvertent saw cut, and repair, if necessary, in accordance with Boeing Service Bulletin 737-25-1231, dated July 7, 1988, or Revision 1, dated January 12, 1989; or if the saw cut exceeds the limit specified in the service bulletin, repair in a method approved by the Manager, Seattle Aircraft Certification Office, FAA, Northwest Mountain Region.

C. Report all inadvertent saw cuts detected during the inspection required by paragraph B., above, to the Manager, Seattle Aircraft Certification Office, FAA, Northwest Mountain Region, within seven days after completion of the inspection.

D. 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, Seattle Aircraft Certification Office, FAA, Northwest Mountain Region.

NOTE: The request should be forwarded through an FAA Principal Maintenance Inspector (PMI), who will either concur or comment and then send it to the Manager, Seattle Aircraft Certification Office.

E. 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.

All persons affected by this directive who have not already received the appropriate service documents from the manufacturer may obtain copies upon request to Boeing Commercial Airplanes, P.O.
