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 wing root rib damage. The FAA is issuing this AD to detect and correct damaged root ribs. The unsafe condition, if not addressed, could result in reduced structural integrity of the wing assembly, which could lead to loss of control of the glider.
Affected ADs
None.
