SCHEDULE OF AIRWORTHINESS DIRECTIVES
Image unavailable in extracted text
Boeing 727 Series Aeroplanes
AD/B727/116
Amdt 1
Fuselage Lap Joints 7/91
Applicability: Model 727 series listed in Boeing SB 727-53-0072 Revision 5. Requirement: Action in accordance with FAA AD 91-06-06 Amdt 39-6921. Compliance: As specified in the Requirement Document.
Background: This Directive introduces a new FAA AD which supersedes two existing FAA ADs, that currently require inspection of the fuselage lap joints for cracks, corrosion, and/or delamination, and repair, if necessary; and modifications of certain lap joints. This action requires additional inspections of certain lap joints and the modification of those lap joints. This amendment is prompted by reports of cracking in these lap joints, and if not corrected, could result in rapid decompression of the aircraft.
