Résumé
This amendment adopts a new airworthiness directive (AD) that applies to certain Raytheon Aircraft Company (Raytheon) Beech Models 1900C, 1900C (C-12J), and 1900D airplanes. This AD requires you to install a spiral wrap around the wing fuel quantity wiring harness and apply an adhesive sealant to the Wiggins couplings on the internal fuel tank wiring carry-through conduit. This AD is the result of reports of chafed or shorted wing fuel quantity harness wires on the affected airplanes. These occurrences were found during regular maintenance inspections. The actions specified by this AD are intended to prevent chafing between the wing fuel quantity wiring harness and the internal wing harness supports at each wing rib location, which could cause the fuel quantity indication to become unreliable. This could leave the flight crew without an indication of the amount of fuel the airplane has during flight. The actions are also intended to prevent fuel from leaking through the wiring carry-through conduit and into the wing tip or wheel well area, which could lead to a fire or explosion.
