Scheibe SF 25 / Bergfalke

Airworthiness Directives; Scheibe-Aircraft-GmbH Gliders

The FAA is adopting a new airworthiness directive (AD) for certain Scheibe-Aircraft-GmbH Model SF 25 C gliders. This AD was prompted by mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI identifies the unsafe condition as severe corrosion on the inner surface of the control stick tube. This AD requires inspecting the left-hand (LH) and right-hand (RH) control sticks for corrosion and, if corrosion is found, replacing the affected control stick. The FAA is issuing this AD to address the unsafe condition on these products.

Airworthiness Directives; Scheibe Flugzeugbau GmbH SF34 and SF34B Gliders

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.
