Original Issue: October 08, 2009 747-53A2605 Revision 3: July 10, 2013 22 of 203 **BOEING SERVICE BULLETIN 747-53A2605 ALERT**  **ALERT C. Reason**  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-53-088. Service Bulletin 747-53A2502 recommends initial and repeat inspections of Non-SUD airplane tension ties from body station (STA) 760 to STA 940 (STA 1040 to STA 1140 for 747SP). Service Bulletin 747-53A2502 was issued to address multiple reports of cracks found in tension ties and adjacent frame structure. **Group 1-16:** Accomplishment of the modification in this service bulletin terminates the repeat inspection requirement of Service Bulletin 747-53A2502. **Group 17-18:** Accomplishment of the modification in this service bulletin does not terminate the repeat inspection requirement of Service Bulletin 747-53A2502, but a new inspection threshold is provided. As a part of a service bulletin validation program, this modification and inspection was completed on airplane RD041 by Service Bulletin 747-53A2605, Original Issue. The modification and inspection completed on airplane RD041 by Service Bulletin 747-53A2605, Original Issue is equivalent to the Revision 2 of this service bulletin. Airplane RD041 has the configuration of a Group 5 airplane. Boeing Service Related Problem (SRP) 747-SRP-53-0200 and 747-SRP-53-0438 are related to this service bulletin. Revision 1 was sent to add more airplanes to the service bulletin effectivity and add Appendix A to give information on methods for disconnecting tension ties. Revision 2 was sent to tell operators that new retrofit drawings have been added for airplanes with barrier net fittings installed under the shear ties located at frame station (STA) 860. Subsequent to the release of Revision 2 of this service bulletin, Boeing has determined that additional inspections are required in the center sections of the tension ties where the tension tie channels are not replaced and where fastener holes are not zero-timed during modification. Revision 3 is sent to add the requirement to do surface high frequency eddy current (HFEC) inspection where fastener holes are not zero-timed during modification on Group 1-16 airplanes. Revision 3 also adds instructions for post-modification inspection of the entire tension tie for Group 1-16 airplanes, and adds effectivity and modification instructions for 747SP (Group 17-18) airplanes. **D. Description** Get access to the Frame to Tension Tie joints in Section 42. 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.

If cracks are found, contact Boeing for repair instructions and do the repair. **Group 1-16:** After modification, do initial and repeat detailed, high frequency eddy current (HFEC), and low frequency eddy current (LFEC) inspections of the tension ties at the compliance time specified in paragraph 1.E., Compliance. If cracks are found, contact Boeing for repair instructions and do the repair. **Group 17-18:** After modification, do initial and repeat detailed and HFEC inspections for cracks in all tension ties, adjacent frame structure, and adjacent structure that attaches to the tension ties. If cracks are found, contact Boeing for repair instructions and do the repair. Revision 1 - No more work is necessary on airplanes changed in accordance with the original issue of this service bulletin. Revision 2 - No more work is necessary on airplanes changed in accordance with the original issue or Revision 1 of this service bulletin. Revision 3 - More work is necessary on airplanes modified in accordance with the original issue, Revision 1, or Revision 2 of this service bulletin. Airplanes previously modified in accordance with this service bulletin will require surface high frequency eddy current (HFEC) inspection for cracks in the forward and aft tension tie channels around fasteners in unmodified areas where fastener holes were not zero-timed during modification. Refer to paragraph 1.E., Compliance for the compliance time of this additional inspection. However, no additional modification is necessary.
