Commercial Airplanes 737 Service Bulletin ALERT SummaryNumber: 737-53A1328Original Issue: July 22, 2014 ATA System: 5331 SUBJECT: FUSELAGE - Skin - Inspection, Preventive Modification and Repairs for Window Corners
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 to inspect for cracks and accomplish a preventive modification and/or limited repairs at fastener locations in window corners of the window belt area between STA 360 to STA 540 and STA 727 to STA 908, left and right side at and between stringers S-11 and S-13. If not corrected, the cracking around the fastener holes could cause multiple window corner skin cracks which can result in rapid decompression and loss of structural integrity.
Aging aircraft investigations by Boeing into 737-300/-400/-500 aircraft with solid skin window belt panels and cycles between 37,842 and 49,050 have discovered cracks at some fastener locations in the window corners of the window belt. This bulletin provides instructions to inspect window corners for cracks and if any crack is found remove by oversizing the hole and/or installing a repair in limited areas. An optional preventive modification is provided for all window corner locations but is not mandated.
Boeing Service Related Problem (SRP) 737-SRP-53-0363 is related to this service bulletin.
Boeing did a fuel burn penalty analysis on the changes given in this service bulletin. Refer to APPENDIX B for the analysis.

ACTION Do the inspections or preventive modification as follows:
Group 1:
Do an external surface High Frequency Eddy Current (HFEC) inspection of the skin at the twelve fastener locations at the upper forward and lower aft corners of each window between STA 360 and STA 540 and at the upper aft and lower forward corners of each window between STA 727 and STA 908. If no cracks are found, do repeat inspections or do the preventive modification. If any crack is found at any of the three corner fastener hole locations (refer to Appendix A) between STA 380 to STA 500C+10.00 or between STA 727E+10.45 and STA 897.45 and is within maximum trim out limits, do a repair of the window corner. If any crack is found within the oversize limits at any hole during the modification, accomplish crack clean up instructions and complete modification. If any crack beyond the maximum oversize hole limit is found in the skin outside the area of the three corner fastener hole locations at any station contact Boeing for repair instructions and do the repair. If any crack beyond the maximum oversize hole limit is found in the skin at any of the three corner fastener hole locations between STA 360 to STA 380, STA 500C+10.00 to STA 540, STA 727 to STA 727E+10.45 and between STA 897.45 to STA 908, contact Boeing for repair instructions and do the repair. If any crack or corrosion is found during accomplishment of the repair contact Boeing for repair instructions and do the repair.
Do a post repair inspection around each fastener location in the repaired area. If any crack is found, contact Boeing for repair instructions and do the repair.
Group 2:
Do an external surface HFEC inspection of the skin at the twelve fastener locations at the upper forward and lower aft corners of each window between STA 360 and STA 540 and at the upper aft and lower forward corners of each window between STA 727 and STA 908. If no cracks are found, do repeat inspections or do the preventive modification. If any crack is found within the oversize limits at any hole during the modification, accomplish crack clean up instructions and complete modification. If any crack beyond the maximum oversize hole limit is found in the skin at any of the twelve fastener locations which includes the three corner fasteners between STA 360 to STA 540 and STA 727 to STA 908, contact Boeing for repair instructions and do the repair.
