Required actions
Within 90 days after the effective date of this AD and thereafter at intervals not to exceed 12 months, inspect the pushrod, joint head, mount, and bell crank of the flaperon control of the wings for corrosion and other damage, in accordance with Action 1 in Schempp-Hirth Flugzeugbau GmbH Working Instructions for Technical Note No. 349-42/825-57, Revision 4, dated August 31, 2020, and before further flight, repair or replace the affected part, as applicable, in accordance with Action 2 in Schempp-Hirth Flugzeugbau GmbH Working Instructions for Technical Note No. 349-42/825-57, Revision 4, dated August 31, 2020.
Unsafe condition
This AD was prompted by 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 severe corrosion on the inboard flaperon actuation push rods and ball bearing connecting the flaperon push rod to the bell crank inside the wing. The FAA is issuing this AD to prevent hard steering and increased play. The unsafe condition, if not addressed, could result in reduced control of the glider.
Affected ADs
None.
