Airworthiness Directive · Amendment 39-9094 · Hawker Beechcraft Corporation Airplanes
Hawker Beechcraft Corporation Airplanes
Superseded. A later AD replaced this one: AD 99-21-26. Comply with the one in force.
This AD applies to Hawker Beechcraft Corporation 400, 400A, 400T, MU-300, MU-300-10.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD) that is applicable to all Beech Model 400, 400A, 400T, and MU-300-10 airplanes, and all Mitsubishi Model MU-300 airplanes. This action requires a revision to the Airplane Flight Manual that provides pilots with special operating procedures during icing conditions. This amendment is prompted by the results of icing tests, which demonstrated that ice accumulations on the horizontal stabilizer may cause the airplane to pitch down at certain flaps settings. The actions specified in this AD are intended to prevent uncommanded nose-down pitch at certain flap settings during icing conditions.
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.
