Airworthiness Directives; Boeing Model 737 Airplanes

The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 737 airplanes. This AD requires, for certain airplanes, a one-time detailed inspection for interference between a clamp assembly and the wires behind the P15 refuel panel, and corrective actions if necessary. For certain other airplanes, this AD requires a one-time detailed inspection for discrepancies of the wires behind the P15 refuel panel; and corrective and related investigative actions if necessary. This AD is prompted by evidence of chafed wiring behind the P15 refuel panel and arcing to the back of the P15 refuel panel and adjacent wing structure. We are issuing this AD to detect and correct chafing of the wiring behind the P15 refuel panel, which could lead to arcing and fire with consequent airplane damage and injury to refueling personnel.
