This AD was sent previously to all known U.S. owners and operators of these helicopters and supersedes Emergency AD 2015-22-52, dated October 28, 2015. This AD requires revising the rotorcraft flight manual (RFM) to stop performing the yaw load compensator check during preflight procedures and instead perform it during post-flight procedures after rotor shut-down. This AD also requires the yaw servo hydraulic switch [[Page 74983]] to be in the ``ON'' position before taking off. This AD is prompted by two accidents and one incident of Airbus Helicopters Model AS350B3 helicopters. From preliminary investigations, loss of tail rotor (T/R) control during takeoff was evident in each event. These actions are intended to prevent takeoff without hydraulic pressure in the T/R hydraulic system, loss of T/R flight control, and subsequent loss of control of the helicopter.

The serial numbers of airplanes manufactured in Japan by Mitsubishi Heavy Industries, Inc. (MHI) under TC A2PC have no suffix. Compliance: Within the next 200 flight hours or five (5) calendar months, whichever occurs first, unless already accomplished per the original version of this AD. To minimize the possibility of confusion in autopilot/manual electric pitch trim disconnect/interrupt switch location and function, accomplish the following:(a) Modify the control yoke in the affected model airplanes as follows: (1) For MU-2B-35 Model airplanes equipped with a King KFC 300 Automatic Flight Control System (AFCS) and a Sperry Manual/Electric Pitch Trim System, in accordance with Bendix/King Certification Bulletin No. CB10, KPN 006-0712-00, no revision, or (2) For MU-2B-36 Model Airplanes equipped with a Sperry SPZ-200 AFCS and a MAI Manual/Electric Pitch Trim System, in accordance with MHI Kit - Sperry SPZ-200AP Disengagement Drawing, 035A-985006, no revision. (b) Prior to returning the airplane to service, accomplish a visual configuration check and a system functional ground test on all MU-2B, MU-2B-10, -15, -20, -25, -26, -26A, -30, -35, -36, -36A, -40, and -60 airplanes, except those airplanes which have complied with AD 88-13-01, dated June 8, 1988, as follows: (1) Visually verify that: (i) The autopilot disconnect and trim disconnect/interrupt functions are combined on one button mounted on the outboard control wheel grip, and is so oriented that it is easily activated by the pilot/copilot. (ii) The autopilot disconnect and trim disconnect/interrupt button is properly and legibly labeled to indicate functions. (iii) The button is red in color. (iv) There are no other red buttons nearby that could be mistaken for the autopilot disconnect. (v) The autopilot circuit breaker is properly labeled. (2) Perform an operational check of the autopilot disconnect and trim disconnect/interrupt button to confirm its correct functioning by disconnecting/interrupting the autopilot and the trim systems, as follows: (i) With the manual electric pitch trim system armed, press the trim button to cause the manual pitch trim wheel to rotate, then verify that after each of the following operations is performed, the manual pitch trim wheel stops moving when: (A) The disconnect/interrupt switch is fully depressed; (B) The master electric power switch is positioned to "OFF"; (C) The radio master switch is positioned to "OFF" (if installed and so configured); (not applicable to MU-2B airplanes equipped with Sperry SPZ-500 autopilots); (D) The electric trim circuit breaker is pulled. (On some MU-2B airplanes without an electric trim circuit breaker, the autopilot circuit breaker/switch is used to disconnect the system in lieu of the electric trim circuit breaker.) NOTE 2: It is very important to verify that the manual pitch trim wheel stops moving after each of the above operations of paragraph (b)(2)(i). (ii) With the autopilot system engaged, verify: (A) That the autopilot system can be overpowered by pushing or pulling on the control yoke; and, (B) That, while overpowering the autopilot, the manual pitch trim wheel stops moving and the autopilot disconnects when each of the following operations is performed: (I) The disconnect/interrupt switch is depressed; (II)The autopilot master switch or the radio master switch or the engage/disengage switch on the autopilot controller (as appropriate), is positioned to "OFF" (On some MU-2B airplanes not equipped with an autopilot master switch beside the controller, the radio master switch must be used to disconnect the system in lieu of the autopilot master switch.); On MU-2B airplanes equipped with Sperry SPZ-500 autopilot: (aa) the master electric power switch is positioned to "OFF"; (bb) the "GA" go-around switch on the left power lever is depressed; (III) The autopilot circuit breaker is pulled. NOTE 3: It is very important that the manual pitch trim wheel stops moving after each of these operations.

94-09-11 R1: This amendment rescinds an existing airworthiness directive (AD), applicable to certain Raytheon Model BAe.125 Series 1000A Airplanes and Model Hawker 1000 airplanes. That AD currently requires inspections of the thrust reverser system for integrity, and correction of any discrepancy found. The requirements of that AD were intended to prevent a significant reduction in the controllability of the airplane due to an in-flight deployment of a thrust reverser. Since the issuance of that AD, the FAA has issued a separate AD that requires the accomplishment of modifications that terminate the requirements of the existing AD.
