AI Floatplane Effects Problem

[mmann]

When I converted the default FSX Beaver to create an AI compatible model, I have run into a snag with the water effects (wake and spray) not stopping. The effect starts up on taxi, shuts off when the model is in the air, starts up again upon landing and taxiing to dock but then doesn't stop when the AI Beaver stops and shuts off the engine. I have posted this twice at FSDeveloper.com but have received no explanation for this problem, so I thought I would post it here at SOH.
