AD Schempp-Hirth Ventus modellen

Bericht door Jan Ritsma » 19 mar 2020, 07:00

Severe corrosion has been found on the inboard flaperon actuation push rod of some sailplanes.
Subsequent investigation determined that, when water ballast is dumped in flight, some water may
be sucked into the wing upper side and enter the wing via the flaperon push rod. Intruding water
may cause corrosion especially on the ball bearing connecting the flaperon push rod to the bell
crank inside the wing.
