Airworthiness Directive · Amendment 39-16226 · Landing gear
Hawker Beechcraft Corporation Model G58 Airplanes
This AD applies to Model G58 airplanes, serial numbers TH-2125 through TH-2172 and TH-2174 through TH-2220, that are certificated in any category.
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.
To address this problem, you must do the following, unless already done:
| Actions | Compliance | Procedures |
|---|---|---|
| (1) Inspect the installation of the stand-off hardware between the heater fuel line and heater over-temperature sensor wires for minimum clearance | Within the next 50 hours time-in-service (TIS) after April 15, 2010 (the effective date of this AD) or within the next 12 months after April 15, 2010 (the effective date of this AD), whichever occurs first | Follow Hawker Beechcraft Mandatory Service Bulletin SB 32-3898, dated November 2008. |
| (2) If, during the inspection required in paragraph (f)(1) of this AD, the stand-off hardware is not installed or it does not maintain the minimum clearance, install stand-off hardware as specified in the service information | Before further flight after the inspection where the missing stand-off hardware and/or inadequate clearance was found | Follow Hawker Beechcraft Mandatory Service Bulletin SB 32-3898, dated November 2008. |
| (3) Inspect the brake reservoir line and the fuel heater power wire for damage | Within the next 50 hours TIS after April 15, 2010 (the effective date of this AD) or within the next 12 months after April 15, 2010 (the effective date of this AD), whichever occurs first | Follow Hawker Beechcraft Mandatory Service Bulletin SB 32-3898, dated November 2008. |
| (4) If, during the inspection required in paragraph (f)(3) of this AD, damage is found, repair or replace damaged tubing and/or wiring found | Before further flight after the inspection where damaged tubing and/or wiring was found | Follow Hawker Beechcraft Mandatory Service Bulletin SB 32-3898, dated November 2008. |
| (5) Inspect the installation of the stand-off hardware between the brake reservoir line and the fuel heater power wire for minimum clearance | Within the next 50 hours TIS after April 15, 2010 (the effective date of this AD) or within the next 12 months after April 15, 2010 (the effective date of this AD), whichever occurs first | Follow Hawker Beechcraft Mandatory Service Bulletin SB 32-3898, dated November 2008. |
| (6) If, during the inspection required in paragraph (f)(5) of this AD, the stand-off hardware is not installed or it does not maintain the minimum clearance, install stand-off hardware as specified in the service information | Before further flight after the inspection where the missing stand-off hardware and/or inadequate clearance was found | Follow Hawker Beechcraft Mandatory Service Bulletin SB 32-3898, dated November 2008. |
