Summary
We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This proposed AD was prompted by reports of skin cracking found at the corners of the aft entry and aft galley doorways. This proposed AD would require repetitive inspections for cracking of the corners of the aft entry and aft galley doorways; and repair if necessary, which would terminate the repetitive inspections of the repaired areas. We are proposing this AD to detect and correct cracking of the corners of the aft entry and aft galley doorways, which could result in rapid decompression and consequent reduced structural integrity of the airplane.
