Airworthiness Directives; Alexander Schleicher GmbH & Co. Model ASK 21 Gliders

This amendment adopts a new airworthiness directive (AD) that applies to Alexander Schleicher GmbH & Co. (Alexander Schleicher) Model ASK 21 gliders. The required action requires replacing the parallel rocker with a part of improved design, and incorporating flight manual revisions. Two incidents of the parallel rocker breaking at the elevator connection on the affected gliders prompted this action. The actions specified by this AD are intended to prevent possible loss of elevator control that could result from a broken parallel rocker.
