Airworthiness Directive · Amendment 39-8842 · The Boeing Company Airplanes
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 certain Boeing Model 727 series airplanes, that requires incorporation of certain structural modifications. This amendment is prompted by an evaluation by the Model 727 Structures Working Group, comprised of aircraft operators, manufacturers, and the FAA. This Working Group evaluated Boeing service bulletins that must be included as part of the "Aging Airplane Structural Modification Program." The actions specified by this AD are intended to prevent degradation in the structural capabilities of the affected airplanes. The actions also reflect the FAA's decision that long term continued operational safety should be assured by actual modification of the airframe rather than repetitive inspections.
