## Summary

We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 757-200, -200PF, and -200CB series airplanes. This proposed AD was prompted by an analysis of the cam support assemblies of the main cargo door which indicated that the existing maintenance program for the cam support assemblies is not adequate to reliably detect cracks before two adjacent cam support assemblies could fail. This proposed AD would require an inspection to determine part numbers, repetitive inspections to detect cracking of affected cam support assemblies of the main cargo door, and replacement if necessary. We are proposing this AD to detect and correct cracking of the cam support assemblies of the main cargo door, which could result in reduced structural integrity of the main cargo door and consequent rapid decompression of the airplane.
