AD FAA-2009-1176

We are adopting a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation Model G58 airplanes. This AD requires inspecting the installation of stand-off hardware between the heater fuel line and the heater over-temperature sensor wires and also brake reservoir tubing and the heater fuel pump wiring for minimum clearance and installing acceptable stand-off hardware if stand-off hardware is missing or inadequate. This AD results from reports received of a power wire shorting out on the brake reservoir tube. We are issuing this AD to detect and correct inadequate clearance of the brake reservoir tubing and the heater fuel pump wiring, which could result in chafing and shorting out of the electrical wiring and chafing of the tubing carrying flammable fluids. This condition could lead to a fire in the nose wheel well.
