I can't beleive the CAA group the Hughes 500 and the B206 together for the purposes of renewing (the only connection is they share the same engine - very different handling characteristics etc) but they won't group together the R22 and R44.
Then again when has the CAA ever made sense on anything to do with helicopters? It seems like they treat the GA heli world as annoyance.
It's the JAA that made these rules, the UK CAA is only part of the JAA and cannot be held responsible for these stupid rules.
