(1) An “affected part” is as identified in SCHEMPP-HIRTH Flugzeugbau GmbH Technical Note No. 278-25, Revision 1, dated July 9, 2024 (SCHEMPP-HIRTH TN No. 278-25, Revision 1): EL6 lower ball bearing (identified as type 1a) or self-aligning lower ball bearing (identified as type 1b) of the elevator drive fitting.

Unsafe condition
This AD was prompted by reports of a broken outer race component of the lower ball bearing installed in the all-moving horizontal tailplane drive fitting. The FAA is issuing this AD to address this unsafe condition. The unsafe condition, if not addressed, could result in the tailplane drive jamming and loss of control of the glider.
Affected ADs
None.

You just looked this one up by hand
TrackAD holds all 12,278 of them and matches them against the aircraft you actually look after — airframe, engine, propeller and appliances in one pass — then works out what falls due and when.
- Bring your existing list in from a spreadsheet Paste the rows straight out of Excel. Headers like C/W Date and N/A are read for you.
- A copy that works when this does not One file. No internet, no login, no this software running. For the morning something has to be produced and the computer is not cooperating.
- $5 a month, or $50 a year Up to 50 aircraft on either.
