Commercial Airplanes 767 Service Bulletin ALERT SummaryNumber: 767-53A0268Original Issue: April 01, 2015 ATA System: 5363 SUBJECT: FUSELAGE - Section 48 - STA 1582 Aft Pressure Bulkhead Web Inspection at Web to Pressure Chord Joint

THIS BULLETIN IS SENT TO THE OPERATORS OF RECORD OF THE AIRPLANES SHOWN IN PARAGRAPH

1.A., EFFECTIVITY. IF AN AIRPLANE HAS BEEN LEASED OR SOLD, SEND THIS SERVICE BULLETIN TO THE NEW OPERATOR. IF APPLICABLE SPARES HAVE BEEN SOLD, SEND THIS SERVICE BULLETIN TO THE NEW OWNER.

CONCURRENT REQUIREMENTS None.

BACKGROUND Widespread Fatigue Damage (WFD) analysis of the 767, as required by 14 CFR 26.21(b), has resulted in the conclusion that existing MPD Section 9, Airworthiness Limitation Item (ALI) inspection program is not sufficient to preclude the occurrence of WFD in the aft pressure bulkhead to pressure chord joint as the airplane ages.

The aft pressure bulkhead web to pressure chord joint has multiple adjacent identical details which have the potential for Multi-Site Damage (MSD) and the potential for WFD. 14 CFR 26.21 requires evaluation of such designs for the potential for WFD and implementation of the appropriate service actions to ensure that WFD is precluded before the Limit of Validity (LOV). Boeing has not received any reports of cracks in the bulkhead web to pressure chord joint. Accomplishment of the inspection described in this service bulletin will enable detection and repair of cracks if they should occur, at the STA 1582 Aft Pressure Bulkhead Web to Pressure Chord joint.

If Widespread Fatigue cracking is not found and repaired, the cracks can rapidly link up and can result in possible rapid decompression and loss of structural integrity.

The aft pressure bulkhead web to pressure chord joint affected by this service bulletin has been determined to be structure that is susceptible to WFD.
