Is the Ercoupe the only certified tricycle gear aircraft that meets the LSA criteria?
It depends on what you want.
If you are asking out of general scholastic interest, then no. Ercoupe is not the only one. Quicksilver GT-500 is a certified tricycle gear airplane that is LSA Eligible or SP Eligible, however you want to call it.
If you just want an LSA that is actually a certified airplane by the miracle of paperwork, then you have a few options
- Jabiru J-230 is certified in Australia in 750 kg class, even has 4 seats.
- WAC Spirit is certified in Colombia (IIRC), again in 750 kg class.
- Maghani Sky Arrow 600 comes with a certified version - in U.S.! However, critically, its certified version ships with Rotax-912S certified engine, so if you buy a Sky Arrow LSA, it's not exactly the same as Sky Arrow Part 23. Airframe is the same.
- I am not entirely sure, but I think SeaMax is certified in Brasil.
and finally
- Tecnam Sierra is certified in Europe for IFR
