Airworthiness Directive · Amendment 39-18858 · Engine
DG Flugzeugbau GmbH
Superseded. A later AD replaced this one: AD 2018-07-22. Comply with the one in force.
This AD applies to DG Flugzeugbau GmbH DG-500MB gliders, all serial numbers, that are:
(1) Equipped with a Solo 2625 02 engine modified with a fuel injection system following the instructions of Solo Kleinmotoren GmbH Service Bulletin (SB)/Technische Mitteilung (TM) 4600-3 “Fuel Injection System” and identified as Solo 2625 02i; and
(2) certificated in any category.
We are adopting a new airworthiness directive (AD) for DG Flugzeugbau GmbH Model DG-500MB gliders that are equipped with a Solo 2625 02 engine modified with a fuel injection system following the instructions of Solo Kleinmotoren GmbH Technische Mitteilung (TM)/ Service Bulletin (SB) 4600-3 "Fuel Injection System" and identified as Solo 2625 02i. 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 possible in-flight engine shut-down and engine fire due to failure of the connecting stud for the two fuel injector mounts of the engine redundancy system. We are issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, within the next 60 days after May 26, 2017 (the effective date of this AD), modify the engine redundancy system following the actions in Solo Kleinmotoren GmbH Technische Mitteilung (English translation: Service Bulletin), Nr. 4600-5, Ausgabe 2 (English translation: Issue 2), dated December 12, 2014.
Note 1 to paragraph (f) 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.
This AD allows credit for modification of the engine redundancy system as required in paragraph (f) of this AD if done before the effective date of this AD following Solo Kleinmotoren GmbH Technische Mitteilung (English translation: Service Bulletin), Nr. 4600-5, Ausgabe 1 (English translation: Issue 1), dated November 24, 2014.
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.
