Summary
We propose to supersede Airworthiness Directive (AD) 2017-11- 03 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 Kleinmoteren GmbH Technische Mitteilung (TM)/Service Bulletin (SB) 4600-3 ``Fuel Injection System'' and identified as Solo 2625 02i. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated 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 failure of the connecting rod bearing resulting from too much load on the rod bearings from the engine control unit. This proposed AD adds DG Flugzeugbau GmbH Model DG-1000M gliders equipped with Solo 2625 02i engines to the applicability. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
