Unsafe Condition

Jamming between the double two-ring end of the towing cable and the deflector angles of the C.G. release mechanism was reported. Subsequent investigation identified incorrect geometry of the deflector angles of the affected part as likely cause of the jamming. This condition, if not detected and corrected, could lead to failure to disconnect the towing cable, possibly resulting in reduced or loss of control of the sailplane.
