Airworthiness Directive · Amendment 39-18150 · Engine
DG Flugzeugbau GmbH Gliders
Superseded. A later AD replaced this one: AD 2015-09-04 R1. Comply with the one in force.
This AD applies to DG Flugzeugbau GmbH Model DG-1000T gliders, all serial numbers, that are:
(1) Equipped with a Solo Kleinmotoren Model 2350 C engine; and
(2) Certificated in any category.
We are adopting a new airworthiness directive (AD) for DG Flugzeugbau GmbH Model DG-1000T gliders equipped with a Solo Kleinmotoren Model 2350 C engine that supersedes AD 2013-22-14 R1. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as engine shaft failure with consequent propeller detachment. We are issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, do the following actions:
(1) As of November 25, 2013 (the effective date retained from AD 2013-22-14), do not operate the engine unless the engine is modified following instructions that are FAA-approved specifically for this AD. Contact the FAA office identified in paragraph (g)(1) of this AD to get more information about obtaining such instructions.
(2) Modification of an engine following the instructions in Solo Kleinmotoren Service Bulletin 4603-14, dated April 28, 2014, is not an acceptable modification to comply with paragraph (f)(1) of this AD.
(3) As of May 26, 2015 (the effective date of this AD), place a copy of this AD into the Limitations section of the aircraft flight manual (AFM).
(4) Within the next 30 days after May 26, 2015 (the effective date of this AD), do a one-time inspection (magnetic particle or dye penetrant) of the propeller shaft following Solo Kleinmotoren GmbH Anleitung zur Inspektion (English translation: Inspection Instruction), Nr. 4603-1, Ausgabe (English translation: dated) March 26, 2015.
Note 1 to paragraph (f)(4) of this AD: This service information contains German to English translation. The EASA used the English translation in referencing the document. For enforceability purposes, we will refer to the Solo Kleinmotoren service information as it appears on the document.
(5) Within the next 30 days after May 26, 2015 (the effective date of this AD), report the results of the inspection required in paragraph (f)(4) of this AD to Solo Kleinmotoren GmbH. Include the serial number of the engine and the operational time since change of the axle in your report. You may find contact information for Solo Kleinmotoren GmbH in paragraph (i)(3) of this AD.
