A document from 2009 must be a bit out by now..... I don't know how much the 2200hr overhaul costs, but the first Cabri overhaul was estimated at three weeks duration only (
see here) so it's got to be a good deal less than the Robbo equivalent
At the point the first two Cabri overhauls were done in recent weeks (both for Northern Helicopters in Sweden), I heard that analysis was done on operating costs from new, and both aircraft had come in at lower than earlier estimates. How much lower??
There was an S300 v R22 v Cabri comparison done recently in the UK too - perhaps Helicentre can help us on the results if there isn't a publication date embargo?
