CONCURRENT REQUIREMENTS None.
BACKGROUND Based on a structural review of the 737 airplane, incorporation of the modification per this service bulletin is recommended on aging airplanes. This service bulletin gives instructions to inspect the skin and bearstrap in the forward galley service doorway upper and lower corners for cracking. If the work in this service bulletin is not done, undetected cracking in the forward galley service doorway corners could extend and result in rapid loss of cabin pressure and cause unscheduled maintenance.
Six operators have found seventeen cracks in the skin and doublers at the upper corners of the forward galley service doorway on eight airplanes. There were eight cracks reported at the upper aft corner on three airplanes and nine cracks in the skin at the forward corner on five airplanes. The airplanes had accumulated from 29,000 to 47,300 flight hours and from 40,500 to 60,800 flight cycles. Cause of the cracking is attributed to fatigue from pressurization cycles.
There have been nine reports of cracking at the upper forward and aft corner fastener locations of the forward galley service doorway in airplanes beyond the effectivity of Revision 3 of this service bulletin. A 0.5 inch long crack was reported on an airplane with 23,426 total flight cycles. Two cracks were reported common to the upper forward and aft corner radius fastener locations of the forward galley service doorway on airplanes that had incorporated the preventive modification in accordance with the original issue, Revision 1, 2 and 3 of this service bulletin. Multiple cracks were reported outside the inspection area of Revision 3 of this service bulletin common to the upper forward and aft door corners of the forward galley service doorway. A 6.5 inch long bearstrap crack was reported just below the upper forward corner inspection zone. The airplane had accumulated 59,804 total flight cycles.

Service bulletin 737-53-1074 provides inspection, preventive modification and repair instructions for the forward galley service doorway lower forward and aft corner areas for 737 airplane line numbers 1 thru 1014. Multiple cracks have been reported common to the skin and bearstrap at the lower forward and aft doorway corners in 737 airplane line numbers 1015 thru 3132 that are beyond the effectivity of service bulletin 737-53-1074. Several cracks ranging from 0.5 inch to 2 inches were reported in the skin and bearstrap at the lower forward doorway corner on airplanes that had accumulated between 44,796 and 73,109 total flight cycles. Multiple cracks ranging from 0.03 inch to 2.5 inches were reported in the skin and bearstrap at the lower aft doorway corner on airplanes that had accumulated between 28,040 and 70,456 total flight cycles. New inspections have been added to service bulletin 737-53A1116 for cracking of the forward galley service doorway lower forward and aft corners for all airplanes within this service bulletin's effectivity. After accomplishing the inspections in accordance with service bulletin 737-53A1116 Revision 4, operators do not need to accomplish service bulletin 737-53-1074 inspections for the forward service doorway lower corners.
