## Summary

We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This proposed AD was prompted by reports of fatigue cracks found in the upper corners of the forward entry door skin cutout. This proposed AD would require repetitive inspections for cracking in the upper corners of the forward entry door skin cutout, and repair if necessary. Accomplishment of this repair or a preventive modification would terminate the repetitive inspections. This proposed AD also would require repetitive post-modification and post-repair inspections. We are proposing this AD to detect and correct cracking in the doorway upper corners, which could result in cabin depressurization.
