There is a lot to like about a single-engine turbine (jet or prop). Greatly improved reliability over piston twins, good power and speed, but reasonable (almost piston-like) fuel burns. A twin jet is going to be expensive to run, even a Mustang.





Turbine engine fuel flows are proportional to speed and weight. The fuel flow doesn't care if you get the speed out of one or two engines.

A twin engine C425 and a TBM700 both go about the same speed at FL250 with about the same FF. In the equivalent $/nm of DOC one or two engines do not make a lot of difference.

The savings of a single engine are in less weight, less systems, and less OH expense, all at the cost of less redundancy.

Dave -

I've been very pleased with Socata's service and general responsiveness, as well as with my local service center (Cutter @ TKI). In the most recent Pro Pilot magazine survey, Socata's service/support ranked a close second to Pilatus and ahead of both Cessna and Hawker/Beech among turboprops.

About 70% of the 530+/- TBM 700/850s are US based. Perhaps as a result of this US predominance, I have seen no effects of currency fluctuations. All pricing is in dollars and does not vary any more than I've seen with other makes. My sense is that competitive factors control pricing.

As Allen mentioned, there's a lot of good information and advice available at the the tbmowners.org site. And feel free to PM me if you'd like to discuss it in more detail.

Best,
Mac
