Airworthiness Directive · Amendment 39-14785 · Raytheon (Beech) Model 400, 400A, and 400T Series Airplanes; and Raytheon (Mitsubishi) Model MU-300 Airplanes
Raytheon (Beech) Model 400, 400A, and 400T Series Airplanes; and Raytheon (Mitsubishi) Model MU-300 Airplanes
This AD applies to all Raytheon (Beech) Model 400, 400A, and 400T series airplanes; and Raytheon (Mitsubishi) Model MU-300 airplanes; certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Raytheon (Beech) Model 400, 400A, and 400T series airplanes; and Raytheon (Mitsubishi) Model MU-300 airplanes. This AD requires revising the airplane flight manual to modify the Operating Limitations, Abnormal Procedures, and Normal Procedures, as applicable, for flight in icing conditions. This AD results from multiple reports of high- altitude, dual-engine flameouts on airplanes operating in certain meteorological conditions. We are issuing this AD to advise the flightcrew that the buildup of ice on certain internal areas of the engine could result in a dual-engine flameout and what action they must take to avoid this hazard.
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 7 days after the effective date of this AD, revise the Operating Limitations, Abnormal Procedures, and Normal Procedures sections, as applicable, of the applicable AFM to include the information in the Raytheon temporary changes (TCs), all dated September 15, 2006, as specified in Table 1 of this AD.
Note 1: The actions required by paragraph (f) of this AD may be done by inserting a copy of the applicable TC into the applicable AFM. When the information in the applicable TC has been included in the AFM, the general revisions may be inserted in the AFM and the copy of the applicable TC may be removed, provided the relevant information in the general revisions is identical to that in the applicable TC.
