Airworthiness Directive · Amendment 39-9215 · Schempp-Hirth Flugzeugbau GmbH Gliders
Schempp-Hirth Flugzeugbau GmbH Gliders
This AD applies to Schempp-Hirth Flugzeugbau GmbH Cirrus.
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 Schempp-Hirth Cirrus and Cirrus VTC sailplanes. This action requires modifying the airbrake actuating lever and replacing the airbrake system coupling balls. Reports of the coupling balls on the airbrake actuating lever breaking at the threaded end on several of the affected sailplanes prompted this action. The actions specified by this AD are intended to prevent airbrake system failure caused by the above condition, which, if not detected and corrected, could result in sailplane controllability problems.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
