Trying not to publish a novel here, I'll just try to hit the high spots, sorry if it goes too long:
Yesterday we had our sixth, and last of the year club fun fly contest. The clubs "go to when you are in trouble" test pilot landed his Webra 32 powered fun fly plane after the first round. This guy usually practices very safe flying techniques. We have rules about not taxiing through the pits with established shut off lines, but he did taxi the plane quite a ways on the wrong side of the line. When he went to shut off the engine by pulling down the throttle trim, apparently the servo pulled the clevis off of the throttle arm. (the silicone retainer tube broke from old age) Webra 32's have a pretty strong spring behind the throttle barrel. When this happened, the throttle went to full. So, we now have a Webra 32 with a 10X4 APC prop on the ground pointed at a group of pilots at full throttle. If it were anyone else in our group but this guy, I think really bad things would have happened. He steered the plane around in a tight circle with guys leaping out of the way of that 14,000+ RPM spinning veg-o-matic prop. When he had a clear shot at the runway, he took it back off and flew it around until it ran out of fuel. It took longer to read this than it actually happened. Apparently, the planets were lined up correctly and the airplane gods weren' t in the mood for a human sacrifice. The point here is accidents can and do happen when you least expect them.
