The purchase price for five aircraft, and all the spares was $2.5 million. The logistics department started to add up the spares total, but get fed up and stopped at $4 million.
There was a cost to the refurbishment and conversion of course.
One interesting fact was that the elastomeric bearings had sagged with lack of use, we asked Sikorskys advice, and they said, "the heads are safe to fly like that, but the bearings will probably not last as long as normal".
In the event, the aircraft were very smooth, and our local rep. said that one of them, (it might have been KR) was the smoothest 76 he had ever flown in.
