Dennis, I bow to your superior knowledge regarding the MD369HM but, since there is only one example of this variant on the UK register, I doubt that it will influence the CAA's decision to any significant degree.
The main problem is that these decisions are being made, in the vast majority of cases, by non-pilots who have little or no knowledge or experience of the flight training industry. Whilst this will make little difference under EASA, when the CAA will have no power to 'interpret' the legislation, right now it is putting UK industry at a very real commercial disadvantage against it's European competitors.
btw. the Robinsons do not have 'swing over' controls; this term refers to a single set of controls that can be re-positioned in flight in front of either the left or right seat - you don't see too many of those in helicopters! But, then, JAR-FCL 2 was originally a virtual word-for-word copy of JAR-FCL 1 with 'aeroplane' replaced with 'helicopter'.
