AD 95-11-15 R1 64 FR 20142

This amendment revises Airworthiness Directive (AD) 95-11-15, which currently requires replacing the parallel rocker with a part of improved design and incorporating flight manual revisions on all Alexander Schleicher Segelflugzeugbau (Alexander Schleicher) Model ASK 21 gliders. AD 95-11-15 was the result of two incidents of the parallel rocker breaking at the elevator connection on the affected gliders. Since that time, the FAA has determined that the AD should only affect those Model ASK 21 gliders equipped with the automatic elevator connection. This AD retains the actions of AD 95-11-15, but only for those gliders with the automatic elevator connection incorporated. The actions specified in this AD are intended to continue to prevent possible loss of elevator control that could result from a broken parallel rocker.
