Mitsubishi Heavy Industries, Ltd. Airplanes
Superseded. A later AD replaced this one: AD 2007-17-09. Comply with the one in force.
This AD applies to Mitsubishi Heavy Industries, Ltd. MU-2B-10, MU-2B-15, MU-2B-20, MU-2B-25, MU-2B-26, MU-2B-30, MU-2B-35, MU-2B-36.
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 applies to certain Mitsubishi Heavy Industries, Ltd., (Mitsubishi) MU-2B series airplanes. This action requires reducing the maximum deflection of the elevator nose-down trim to a 1-degree to 3-degree range. Analysis of service history on the affected airplanes has revealed one accident and two incidents where the existing elevator nose-down trim deflection caused excessive control wheel force. The actions specified by this AD are intended to prevent excessive control wheel force caused by extreme elevator nose-down trim deflection, which could result in loss of control of the airplane.
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.
