Required actions
For the purpose of this AD, the definitions in paragraphs (g)(1) through (3) of this AD apply. (1) An “affected part” is a steel frame engine mount having part number (P/N) 10M112. (2) A “serviceable part” is an affected part which is new (never previously installed on any glider), or a part that has passed the engine mount inspection prior to installation in accordance with Instructions 2 of DG Aviation GmbH Technical Note No. TN 1000/51, Doc. No. TM1000-51 FE-29-01, Issue 01.d, dated February 26, 2025 (DG Aviation GmbH TN TM1000-51 FE-29-01, Issue 01.d). (3) The “Old MM” task is the DG Aviation Maintenance Manual (MM) for DG-1000M, task 4.10.2 “Mounting and tensioning of the drive belts”, issued before January 2025.
Unsafe condition
This AD was prompted by reports of the engine mount cracking near the propeller head. The FAA is issuing this AD to detect and correct indications of structural failure of the engine mount. The unsafe condition, if not addressed, could result in loss of power transmission to the propeller and reduced or loss of control of the glider.
Affected ADs
None.
