Does the DA-2 qualify as a LSA?

No. In order to qualify as an LSA the aircraft must stall clean at no more than 51 mph. The primary reason for the high stall on the DA-2 (60mph) is the high wing loading which makes for a nice stable good performing aircraft but does not work for lower stall speeds. In order to reduce the stall speed we would need to increase the wing area which in turn requires re-engineering of all the structural components of the wing and attachments.
