Airworthiness Directive · Amendment 39-9349 · Scheibe-Flugzeugbau GmbH Gliders
Scheibe-Flugzeugbau GmbH Gliders
This AD applies to Scheibe-Flugzeugbau GmbH SF34.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
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.
