The final straw that broke the camels back for the CAA ( to be fair of the 5 members of the CAA who were doing the paperwork 3 wanted it to fly one was dead against) was the direct comparison that I laid before him.
Took all the component cards from a 369HM ( mil spec right hand drive machine but with normal c of a ) on the UK reg copied them removing the record of what ac they were fitted to. Did the same with the OH6. Only difference were some dash numbers indicating a higher mod state. Gave both sets to CAA surveyor and asked him to tell me which was the OH6, guess what !!!!!
month later I was air testing the machine with CAA chief test pilot
As for Phil who owns both machines great guy with a real passion I take my hat of to him, looking forward to the cobra ! He is always up for a curry and beer if in Blackpool
