The Boeing Company Airplanes
This AD applies to The Boeing Company 727-100 Series, 727-100C Series, 727-200 Series, 727-200F Series, 727 Series, 727C Series.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD), applicable to all Boeing Model 727 series airplanes, that requires inspections of certain fuselage frames for cracks, and modification, if necessary; inspections to detect cracks in certain frame gussets, and replacement, if necessary; and inspections at certain body stations to detect open pilot holes and to detect cracks in any open pilot hole found, and repair and modification, if necessary. This amendment is prompted by reports of cracked frames and open pilot holes. The actions specified by this AD are intended to prevent frame failures and consequent rapid decompression of the cabin.
