Summary
This document proposes to adopt a new airworthiness directive (AD) that would apply to certain Alexander Schleicher GmbH & Co. (Alexander Schleicher) Model ASW-27 sailplanes. The proposed AD would require inspecting the elevator control circuit clearance inside the fuselage tail boom to the fin intersection to assure a clearance of at least 2.5 millimeters (mm) (\1/10\-inch wide), and adjusting any clearance that does not meet the criteria. The proposed AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. The actions specified by the proposed AD are intended to detect interference in the elevator control circuit, which, if not corrected, could result in the elevator control jamming with possible loss of control of the sailplane.
