AD ASK 21 Schleicher richtingsroerbediening

Bericht door Jan Ritsma » 30 aug 2016, 07:26

A temporary rudder control blockage was reported, involving an ASK 21 sailplane equipped with a rudder hand control system. The subsequent investigation revealed significant cable slack in the rudder control system.
This condition, if not detected and corrected, could lead to reduced rudder control, possibly resulting in reduced controllability of the sailplane.
To address this potentially unsafe condition, Schleicher issued ASK 21 Technical Note (TN) 38 to provide instructions to amend the ASK 21 Aircraft Flight Manual (AFM), incorporating updated pre-flight inspection instructions to check the rudder control system of sailplanes modified in accordance with the instructions of Schleicher ASK 21 TN 25 (rudder actuated by hand lever for the front pilot seat) or TN 30 (rudder control by hand for the rear pilot seat).
