Raytheon Model DH.125, HS.125, and BH.125 Series Airplanes; BAe.125 Series 800A (C-29A and U-125) and 800B Airplanes; and Hawker 800 (Including Variant U-125A) and 800XP Airplanes; Equipped with TFE731 Engines
This AD applies to Raytheon Model DH.125, HS.125, and BH.125 series airplanes; BAe.125 series 800A (C-29A and U-125) and 800B airplanes; and Hawker 800 (including variant U-125A) and 800XP airplanes; certificated in any category; equipped with TFE731 engines; as identified in Raytheon Service Bulletin SB 26-3496, dated November 2003.
The FAA is adopting a new airworthiness directive (AD) for certain Raytheon Model DH.125, HS.125, and BH.125 series airplanes; BAe.125 series 800A (C-29A and U-125) and 800B airplanes; and Hawker 800 (including variant U-125A) and 800XP airplanes. This AD requires installing insulating blankets on the engine compartment firewall and the wire harness passing through the firewall fairlead. This AD is prompted by a report indicating that insulation on the wire harness passing through the firewall fairlead ignited on the fuselage side of the firewall. We are issuing this AD to prevent a fire in the engine compartment from causing possible ignition of outgassing wire insulation on the fuselage side of the firewall, which could lead to an uncontrollable fire in the fuselage.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 12 months after the effective date of this AD, install insulating blankets on the engine compartment firewall and the wire harness passing through the firewall fairlead, by doing all the actions in accordance with the Accomplishment Instructions of Raytheon Service Bulletin SB 26-3496, dated November 2003.
The service bulletin describes procedures for reporting accomplishment of the service bulletin to the manufacturer; however, this AD does not require that action.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
