Commercial Airplanes 747 Service Bulletin ALERT SummaryNumber: 747-53A2605Original Issue: October 08, 2009 Revision 1: May 27, 2010 ATA System: 5312 SUBJECT: FUSELAGE - Center Section - Tension Ties and Frames - Modification and Inspection
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 This service bulletin gives instructions for modification of upper deck tension ties and adjacent frame structure on non stretched upper deck (Non-SUD) airplanes. The tension ties have been determined to be structure that is susceptible to Widespread Fatigue Damage (WFD). WFD can cause tension ties to become severed or disconnected from the frames. Severed or disconnected Tension Ties and/or Frames at multiple locations could result in rapid in-flight decompression.
For more information about WFD, refer to Boeing Service Letter 747-SL-53-088B.
Service Bulletin 747-53A2502 recommends initial and repeat inspection of Non-SUD airplane tension ties from body station (STA) 760 to STA 940. Service Bulletin 747-53-2502 was issued to address multiple reports of cracks found in tension ties and adjacent frame structure. Accomplishment of the modification in this service bulletin terminates the repeat inspection requirement of Service Bulletin 747-53-2502.
Federal Aviation Administration (FAA) Airworthiness Directives 2004-07-22 R1 and 2006-01-07 are related to this service bulletin.
Boeing Service Related Problem (SRP) 747-SRP-53-0200 is related to this service bulletin.
ACTION (PRR 85901-68RS) Get access to the Frame to Tension Tie joints at STA 720 through STA 940 or STA 840 through STA 940 depending on the group. At each station, disconnect and remove a section of the tension tie between the frame and approximate Buttock Line (BL) 36. For each frame, remove a specified section of the frame above and below the tension tie attach point. After the existing frame and tension tie structure has been removed and discarded, install new frame and tension tie structure. Do the modification on both sides of the airplane.

Original Issue: October 08, 2009 747-53A2605Revision 1: May 27, 2010 7 of 158
After modification, do initial and repeat inspections of the unmodified areas of the tension ties at the compliance time specified in paragraph 1.E., Compliance. Also, if the airplane will be operated past the post-modification inspection compliance time specified in paragraph 1.E., then contact Boeing for post-modification inspection instructions and do initial and repeat inspections of the modified tension tie and frame structure.
EFFECTIVITY 747-100, 747-100B, 747-200B, 747-200C, 747-200F, 747-400F, and 747SR airplanes. Refer to paragraph 1.A., Effectivity, 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.
