Don't think the GASU techies would agree. Underpowered, prone to cracking, subject of a serious independent safety audit a couple of years ago which got it sent back to Britten Norman. There are plenty of other planes knocking around which could do the job with a turbo prop in the nose. But then again since the Cessna 172 has left Gormo, they can't keep them out of the air, plenty of parts, so why change what's working well.
