CESSNA 180
DURING A BANNER TOW OPERATION, THE PLT TRIED TO RELEASE THE BANNER. WHEN THE BANNER DID NOT DISCONNECT, THE PLT TURNED TO SEE WHAT THE PROBLEM WAS. THE AIRPLANE STALLED AND BEFORE THE PLT COULD REGAIN CONTROL, IT COLLIDED WITH THE TERRAIN. INSPECTION OF THE RELEASE MECHANISM REVEALED THAT THE SET-UP DID NOT COMPLY WITH THE STC.
