## Summary

We propose to adopt a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation Model G58 airplanes. This proposed AD would require inspecting the installation of stand-off hardware between the heater fuel line and the heater over-temperature sensor wires for minimum clearance and installing acceptable stand-off hardware if stand-off hardware is missing or inadequate. This proposed AD would also require inspecting the brake reservoir line and the fuel heater power wire for damage and minimum clearance, replacing any damaged wires and/or lines, and installing stand-off hardware if minimum clearance is not met. This proposed AD results from reports received of a power wire shorting out on the brake reservoir tube. We are proposing 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.
