BACKGROUND
This service bulletin gives instruction for the replacement of the Station (STA) 1582 aft pressure bulkhead due
to Widespread Fatigue Damage (WFD). The WFD analysis of the 767, as required by 14 CFR 26.21(b), has
resulted in the conclusion that the existing MPD Section 9, Airworthiness Limitation Item (ALI) inspection program
is not sufficient to preclude the occurrence of WFD in the aft pressure bulkhead before the Limit of Validity (LOV)
as the airplane ages. If widespread fatigue cracking at aft pressure bulkhead radial web lap splices is not found
and repaired, the cracks can rapidly link up and become large, and can result in possible rapid decompression
and loss of structural integrity.
Boeing has not received any reports of cracks in the aft pressure bulkhead web on line number 176 through
423.
The Aft Pressure Bulkhead has been determined to be structure that is susceptible to Widespread Fatigue
Damage (WFD).
Federal Aviation Administration (FAA) AD 2012-09-08 was released to mandate replacement of the initial
configuration aft pressure bulkhead which was installed on line number 1 through 175 per service bulletin
767-53A0139. Design changes were made to improve the durability of the bulkhead in production at line number
176, and again at line number 424. However, the configuration of aft pressure bulkheads installed on line number
176 through 423, have the same web gage of 0.032 inch as the initial configuration aft pressure bulkhead and
does not provide adequate strength to preclude WFD before the Limit of Validity (LOV).
Boeing Service Related Problem (SRP) 767-SRP-53-0469 is related to this service bulletin.
Accomplishment of the aft pressure bulkhead replacement given in this service bulletin will end the inspections
at aft pressure bulkhead web for indications of "oil cans" and previous "oil can" repairs currently required by
Boeing Service Bulletin 767-53A0105 and AD 2004-14-19.

Accomplishment of the aft pressure bulkhead replacement given in this service bulletin will end the repeat

Accomplishment of the aft pressure bulkhead replacement given in this service bulletin will also end the repeat
inspections of web at pressure chord joint currently required by Boeing Service Bulletin 767-53A0087 and AD

ACTION
Remove equipment for access to the forward and aft sides of the STA 1582 aft pressure bulkhead. Remove the
vertical fin, the tail cone (with the APU installed), the left and right STA 1809.5 center bulkhead, and the horizontal
stabilizer. Disconnect and remove the forward portion of Section 48 (with the aft pressure bulkhead attached)
from Section 46 at STA 1582. Remove the aft pressure bulkhead from Section 48 and install a new aft pressure
bulkhead in accordance with this service bulletin. Attach the modified forward part of Section 48 to Section 46
at STA 1582. Reinstall the horizontal stabilizer and reassemble the STA 1809.5 bulkhead. Reinstall the tail cone
and the vertical fin. Install the equipment that was removed for access to the aft pressure bulkhead. Test disturbed
systems in accordance with this service bulletin.
EFFECTIVITY
767-200 and 767-300 Airplanes. Refer to Paragraph 1.A.1., Airplanes, for the list of affected airplanes.
COMPLIANCE
The Federal Aviation Administration (FAA) will possibly release an Airworthiness Directive related to this service
bulletin. The Airworthiness Directive will make the compliance tasks and times given in this service bulletin
mandatory.
