Airworthiness Directive · Amendment 39-17365 · Flight controls
Diamond Aircraft Industries GmbH Airplanes
Superseded. A later AD replaced this one: AD 2013-04-08 R1. Comply with the one in force.
This AD applies to the following Diamond Aircraft Industries GmbH models and serial number (S/N) airplanes, certificated in any category: H-36 and HK 36 R airplanes, S/Ns 36.300 through 36.414; HK 36 TS airplanes, S/Ns 36.415 and 36.416; and HK 36 TTS airplane, S/N 36.393.
We are adopting a new airworthiness directive (AD) for Diamond Aircraft Industries GmbH Model H-36, HK 36 R, HK 36 TS, and HK 36 TTS airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as installation of an unsuitable self-locking nut on the bell crank of the elevator push rod that can cause failure of the elevator, resulting in loss of control. We are issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, do the following actions following Diamond Aircraft Industries GmbH Mandatory Service Bulletin MSB 36-108 and Diamond Aircraft Industries GmbH Work Instruction WI-MSB 36-108, both dated February 28, 2012:
(1) Within the next 200 hours time-in-service (TIS) after April 9, 2013 (the effective date of this AD) or within the next 12 months after April 9, 2013 (the effective date of this AD), whichever occurs first, replace each elevator bell crank assembly with part number (P/N) 820-2730-12-00, and replace each elevator bell crank mount with P/N 820-2730-11-00.
(2) After April 9, 2013 (the effective date of this AD), only install on the airplane elevator bell crank assemblies with P/N 820-2730-12-00 and elevator bell crank mounts with P/N 820-2730-11-00.
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.
