Light-Sport Aircraft Yahoo group Re: Sting Sport Woodcomp blade loss

And what is that supposed to mean?
The fact that you are thinking that somehow this had possibly something to do with a carb engine and some composite prop ... well I just tried to tell you, that's the wrong direction you are headed in. All Rotax engine for aircraft short of new iS have been carb equipped and have many hours on them and most have run composite props. That's all I wanted to clarify to you. Take it or leave it but keep the below the belt jabs to yourself. Thank you.

In an instant, a loud bang followed by a one tremendous shutter, then total quietness, except for cockpit chatter that starts with “what-the-hell was that”, as you have no idea what happen because the engine is in back. After gliding to a non-event field landing found both carbs were out of their sockets from the initial shock; that stopped the engine. Other than that, no other damage. It is a very, very fast experience.

I had enough time to pull back on the throttle and level out (quickly mind you) to at least try to see what was going on - but by the time I reached a level attitude the engine had quit.

As it stands now the engine mount is bent and the firewall has a crack at one of the mount points. I'll get up to the airport and see it in person on Sunday. Right now I'm working off of reports from other partners in the plane who have seen it first hand.
