AD 95-18-01 60 FR 44421

This amendment adopts a new airworthiness directive (AD) that applies to Scheibe Flugzeugbau GmbH SF34 and SF34B gliders. This action requires adding armature (supportive covering) to both wings, modifying the root rib of the left wing and incorporating changes and operating limitations to the flight manual. Failure of the left wing root rib on one of the affected gliders while in flight prompted this action. The actions specified by this AD are intended to prevent fatigue failure of the wing, which could result in loss of control of the glider.
