Airworthiness Directive · Amendment 39-12871 · Boeing Model 727 Series Airplanes
Boeing Model 727 Series Airplanes
All Model 727 series airplanes, certificated in any category.
This amendment adopts a new airworthiness directive (AD) that is applicable to all Boeing Model 727 series airplanes. This action requires a one-time inspection to find discrepancies of the wire bundles and hydraulic tubing in the aft stairwell area, and corrective action, if necessary. This action is necessary to find and fix such discrepancies, which could result in electrical arcing between the wiring and hydraulic tubing, and consequent fire and damage to adjacent structure. This action is intended to address the identified unsafe condition.
