Airworthiness Directives; Beech Model 400, 400A, 400T, and MU- 300-10 Airplanes, and Mitsubishi Model MU-300 Airplanes Federal Register ↗
Abstract
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.
