STIFFENING OF THE RUDDER SURFACE PANELS
Applicable to all ASW 19 gliders with rudder without upper horn type mass balance, S/Nos. 19019 through 19037, 19040 and 19042 through 19044. Oscillations of the rudder control circuit have been noticed at about maximum speed on days with very high temperatures. The airflow passing over the rudder surface induce 'panel flutter' of the rudder surface panels. According to drawing 190.38.S1 two stringers made of FRP are glued to the inside of the rudder panels. The rudder is opened at its forward joint by the use of a metal saw blade between the hinges.
