## Summary

We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 727-100 series airplanes. This proposed AD is intended to complete certain mandated programs intended to support the airplane reaching its limit of validity (LOV) of the engineering data that support the established structural maintenance program. For certain airplanes, this proposed AD would require repetitive inspections for cracking in stringers or frames until modification, and repair if necessary. We are proposing this AD to detect and correct cracking in stringers or frames originating at or near stringer-to-frame attachment fastener holes, which could result in reduced structural integrity of the airplane, and decompression of the cabin.
