Airworthiness Directive · Amendment 39-13658 · Alexander Schleicher Model ASW 27 Sailplanes
Alexander Schleicher Model ASW 27 Sailplanes
The Federal Register printed this AD without its applicability text. Read it at the link below.
The FAA adopts a new airworthiness directive (AD) for all Alexander Schleicher Model ASW 27 sailplanes equipped with integrated (wet inner surface) water ballast tanks in the wings, which could put the center of gravity (CG) of the sailplane out of the acceptable range. This AD requires you to install a warning placard requiring pilots weighing more than 105 kg (231.5 lbs) to use the rearmost backrest hinge position; and requires you to determine the forward empty CG and make any necessary adjustments. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this AD to correct the CG to the acceptable range when integrated ballast water tanks are installed. Failure of the sailplane to be within the acceptable CG range could result in 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.
