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 Refer to Paragraph 1.B., Concurrent Requirements.
BACKGROUND This service bulletin gives instructions to inspect the Station (STA) 348.2 frame for cracks under the stop fittings.
This service bulletin also gives instructions to inspect for missing fasteners common to the STA 348.2 frame at S-7L through S-15L. Undetected or remaining cracks in the frame will propagate by normal fatigue due to cyclic cabin pressure loading. If cracks continue to propagate, the stop fittings will become ineffective. This can result in a possible rapid decompression and a potential separation of the forward entry door from the aircraft.
Boeing has received reports of cracks in the STA 348.2 frame on six 737-200 cargo airplanes. The STA 348.2 frame is a body frame aft of the forward entry door cutout. The cracks were located under the stop fittings at Stringer 15L and 16L.
Since the release of the original issue of this service bulletin, Boeing has received reports of STA 348.2 frame cracking at S-15L above the two outboard fasteners attaching the frame inner chord and door stop fitting. The cracking was reported on seven passenger airplanes that had accumulated between 19,185 and 64,800 flight cycles. Spares history also shows that seventeen frame chords have been ordered in the last ten years. Cracks have also been found in the outboard chord at S-16L.
Boeing has received reports of ten passenger airplanes with missing fasteners in the STA 348.2 frame inner chord at stringer S-7L through S-15L.
Boeing Service Related Problem (SRP) 737-SRP-53-0149 and 737-SRP-53-0306 are related to this service bulletin.
