I'm bemused by the comments on here re a successful UK GA manufacturing industry before we entered the EEC/EU. Dementia with rose coloured glasses seems to be prevalent!!
Beagle went bust with the Pup, their Airedale product was overweight and didn't sell, the 206 was very pretty but poorly built.
Britten Norman tried with the Nymph to challenge the 152/172 market .................. and failed
Lockspeiser LDA-1 was an interesting concept that nobody wanted
Cranfield A-1 could have been the Extra but it wasn't good enough
CMC Leopard personal jet........... never got past development stages
Trago Mills had the little SAH-1, but it didn't do anything.
ARV 2 showed promise then disappeared.
At the heavier end the BAe 125 was given away as there was no will power to develop a new version. Dassault had no problem and has the very successful Falcon range as a result.
The French have developed the TBM range in addition to the Robin range
The Swiss are coming on strong now with the PC-12 and PC-24
The semi successful Slingsby T-67 was originally a French design that Slingsby then stepped in and bought.
Where, apart from the excellent P&M designs, does the UK have any production facilities, design capability, willing investors?
