JAR a/c class definition
 

I'm looking for the Jar reference concerning definition of aircraft classes- ie what defines an sep, mep, etc (but specifically sep land).
Is there an online jar listing? i really need the rule number (reference).

Thanks

I'm guessing the definiition is one piston engine and wheels or skis, but thats probably a bit simple, right?

Try http://www.jaa.nl/section1/jarsec1.html

Might be some info under JAR-23
