Airworthiness Directive · Amendment 39-10722 · Schempp-Hirth K.G. Model Cirrus Sailplanes
Schempp-Hirth K.G. Model Cirrus Sailplanes
Model Cirrus sailplanes, serial numbers 1 through 50, certificated in any category.
This amendment adopts a new airworthiness directive (AD) that applies to certain Schempp-Hirth K.G. (Schemmp-Hirth) Model Cirrus sailplanes. This AD requires modifying or replacing the connecting rod between the airbrake bellcranks, and replacing the existing 6 millimeter (mm) bolt with an 8 mm bolt. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. The actions specified by this AD are intended to prevent the threaded bolt that is welded to the connecting rod between the airbrake bellcranks from breaking, which could result in loss of airbrake control with a possible reduction/loss of sailplane control.
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.
