Savoia, don`t get too orgasmic about the S76 in the corporate world in the 1980`s. The AS 365N Dauphin family was superior in all respects bar one. Range, speed, ride quality, reliability, running costs, ease of maintenance, powerplant were all superior to the Allison engined S76. The only plus for the S76 was the cabin, which is what has made it popular with owners over the years. The Dauphin cabin, no matter how plush the interior fittings, was always like sitting on cushions on the floor and the back row of seats was always a challenge for ladies in short skirts.
The sad thing for Eurocopter was the EC 155, which addressed the problems of the cabin dimensions, saddled the airframe with a power hungry transmission which then branded the aircraft a duffer.
I think the S76D model has an assured future in that there are still many areas of the world just waking up to the existence of oil and gas reserves and for whom the D model is exactly the right size and cost. In addition, it remains popular in the corporate and charter world on the strength of its comfortable cabin. Perhaps a corporate EC 175 might be the answer.
