Safety Officer Posted December 7, 2012 Report Share Posted December 7, 2012 Hi Ed C. You always wanted to know if someone put a turbo in a CT. Well it has happened. It didn't do that much better with just a fixed pitch prop, but did very well with an in flight adjustable prop. It was slightly faster at the 4K altitude, but was really better at the high altitudes up to 16K. The problem is it is now a completely illegal plane that no one will touch.

Jim Posted December 7, 2012 Report Share Posted December 7, 2012 Why can't it be taken to a straight experimental certificate? Link to comment Share on other sites More sharing options...
Safety Officer Posted December 7, 2012 Author Report Share Posted December 7, 2012 I'm not sure, maybe because it is factory built. It might make a utility class. The other issue is he has to find a mechanic willing to sign it off on the install. Link to comment Share on other sites More sharing options...
Ed Cesnalis Posted December 7, 2012 Report Share Posted December 7, 2012 To marry a 914 to a LSA you need new prop technology. Tecnam is using some but I don't know what it entails. I assume that increasing torque flattens the pitch. Link to comment Share on other sites More sharing options...
Jacques Posted December 7, 2012 Report Share Posted December 7, 2012 914 CT.dochttp://www.flightdes...me&n=175&y=2010 http://www.flightdes...me&n=175&y=2010 The propeller used is not stated though Link to comment Share on other sites More sharing options...
Safety Officer Posted December 7, 2012 Author Report Share Posted December 7, 2012 The engine was a 912 converted to a turbo. The kit cost is about $8.5K with about $6k more for the install. Link to comment Share on other sites More sharing options...
S3flyer Posted December 7, 2012 Report Share Posted December 7, 2012 Don't know the order in which things happened in this case but it would seem that the plane would be a legal ELSA if the plane was converted to ELSA first, then upgraded to a 914. The 914 is an approved LSA engine, right? In-flight adjustable would be the main issue. Link to comment Share on other sites More sharing options...
sandpiper Posted December 7, 2012 Report Share Posted December 7, 2012 In the ELSA category you should be able to do anything you want so long as the light sport parameters are not violated. Link to comment Share on other sites More sharing options...
Safety Officer Posted December 7, 2012 Author Report Share Posted December 7, 2012 The plane is still (was until converted) an SLSA, no sign off for the engine, in flight adjustable prop and possibly too fast. The turbo engine wouldn't be as big as an improvement without the in flight adjustable prop. $15K spent for a plane you can't legally fly or sell. This 912 conversion setup would be better suited for an experimental. Link to comment Share on other sites More sharing options...
chanik Posted December 7, 2012 Report Share Posted December 7, 2012 S3flyer is correct. The plane must be a FULLY COMPLIANT SLSA when it is converted to E-LSA. Even then, it must constrain itself to the LSA rules which means no adjustable prop. Link to comment Share on other sites More sharing options...
