Airworthiness Directive · Amendment 39-17344 · Engine
DG Flugzeugbau GmbH Gliders
This AD applies to DG Flugzeugbau GmbH Model DG-1000T gliders equipped with Solo Kleinmotoren Model 2350 C engines, all serial numbers, certificated in any category.
We are adopting a new airworthiness directive (AD) for DG Flugzeugbau GmbH Model DG-1000T gliders equipped with Solo Kleinmotoren Model 2350 C engines. 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 a material defect of the propeller shaft, most likely caused by a manufacturing error. We are issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, do the following actions:
(1) Within 25 hours time-in-service (TIS) after March 19, 2013 (the effective date of this AD) or 6 months after March 19, 2013 (the effective date of this AD), whichever occurs first, remove the propeller pulley assembly (module) from the engine and inspect the transition region of the part number (P/N) 20 31 211 shaft following the Actions section of Solo Kleinmotoren GmbH Service Bulletin Nr. 4603-13, Issue 1, dated September 24, 2012.
(2) If, during the inspection required by paragraph (f)(1) of this AD, cracks are detected in the P/N 20 31 211 shaft, before further flight, do the following:
(i) Replace the P/N 20 31 211 shaft with an airworthy P/N 20 31 211 shaft; or
(ii) Replace the propeller pulley assembly (module) with an airworthy propeller pulley assembly (module).
