Airworthiness Directive · Amendment 39-15195 · Hawker Beechcraft Model 400, 400A, and 400T Series Airplanes
Hawker Beechcraft Model 400, 400A, and 400T Series Airplanes
This AD applies to Hawker Beechcraft Model 400, 400A, and 400T series airplanes, certificated in any category; as identified in Raytheon Service Bulletin SB 54-3788, dated December 2006.
The FAA is adopting a new airworthiness directive (AD) for certain Hawker Beechcraft Model 400, 400A, and 400T series airplanes. This AD requires modifying the attachment fasteners on the engine cowling panels. This AD results from several reports of loose attachment fasteners found on the engine cowling panels, and subsequently the panels either peeling back or separating from the airplane during flight. We are issuing this AD to prevent failure of the attachment fasteners on the engine cowling panels, which could result in separation of a panel from the airplane, and consequent damage to airplane structure. These conditions could adversely affect continued safe flight and landing of the airplane, or cause injury to people or damage to property on the ground.
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 200 flight hours after the effective date of this AD: Modify the attachment fasteners on the engine cowling panels by doing all the actions in accordance with the Accomplishment Instructions of Raytheon Service Bulletin SB 54-3788, dated December 2006.
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.
