HPH issued Service bulletins: G304CZ-06a); G304CZ17-06a); G304C-06a).

A broken elevator control rod in the vertical fin on a Kestrel
sailplane has been reported. The technical investigation revealed that
water had soaked into the elevator control rod through a control bore
hole and resulted in corrosion damage. The investigation concluded as
well that the corrosion cannot be detected from outside the elevator
control rod. This condition, if not detected and corrected, could lead
to failure of the elevator control rod, possibly resulting in loss of
control of the sailplane.

EASA Airworthiness Directive No. 2012-0073 issued on 30th April 2012.
