Affected ADs (b) None. Applicability (c) This AD affects the following airplane models and serial numbers that are certificated in any category: Type certificate Models Serial Nos. (1) A2PC MU 2B, MU 2B 10, MU 2B 15, MU 2B 20, MU 2B 25, and MU 2B 26. 008 through 312, 314 through 320, and 322 through 347. (2) A2PC MU 2B 30, MU 2B 35, and MU 2B 36 501 through 651, 653 through 660, and 662 through 696. (3) A10SW MU 2B 25, MU 2B 26, MU 2B 26A, and MU 2B 40 313SA, 321SA, and 348SA through 459SA.

Unsafe Condition (d) This AD results from a recent safety evaluation that used a data-driven approach to analyze the design, operation, and maintenance of the MU-2B series airplanes in order to determine their safety and define what steps, if any, are necessary for their safe operation. Part of that evaluation was the identification of unsafe conditions that exist or could develop on the affected type design airplanes. The actions specified in this AD are intended to detect and correct improper rigging of the propeller feathering linkage. The above issue if uncorrected could result in degraded performance and poor handling qualities with consequent loss of control of the airplane. Compliance (e) To address this problem, you must do the following: Actions Compliance Procedures Incorporate the following information into the Limitations Section of the FAA-approved Airplane Flight Manual (AFM): (1) For airplanes listed in Type Certificate No. A2PC insert pages 3 and 4 from Mitsubishi Heavy Industries, Ltd.
