SOCATA TBM-700N

The TBM is a single-engine turboprop built for speed rather than volume: it cruises at 300 knots and more in the flight levels, which is jet territory, in a pressurised six-seat cabin, on a single PT6. It is the aeroplane an owner-pilot buys to do 1,200-mile business trips alone or with two or three others, quickly and at flight levels where the weather mostly is not. Unlike the PC-12 it has no cargo door and a much smaller cabin — it is a fast personal aeroplane, not a utility one. Every TBM ever built is certified as a TBM 700, so the registry name hides thirty years of development. The original 700A of 1990 has a 700 shp PT6A-64 and conventional instruments; the 700B added the wide entry door, the 700C1 a rear cargo compartment, and the 700C2 raised gross weight to 7,394 lb. The TBM 850 of 2006 has the PT6A-66D rated at 850 shp in flight, with the Garmin G1000 standard from 2008. The TBM 900 of 2014 added winglets and a five-blade propeller, the 930 of 2016 the Garmin G3000 touchscreen deck, the 940 of 2019 an autothrottle and automatic de-icing, and the 960 of 2022 a FADEC-controlled PT6E-66XT and autoland. A 1995 TBM 700 and a 2015 TBM 900 are a hundred knots and two generations of cockpit apart on paper that says the same thing.

The constraint is payload. With full fuel the cabin load is around a thousand pounds and in practice a TBM flown to its full range carries the pilot and two or three people, not six. Operating costs are turbine costs — hot section inspections, an eventual overhaul in the high six figures, and Jet-A at around 55-60 gallons an hour. It is fast and slippery and demands real energy management on descent and approach; the type's accident record includes several loss-of-control events involving pilots transitioning from slower aircraft. No type rating is required at this weight, but every insurer requires formal initial and recurrent simulator training, and a mentor pilot requirement for low-time owners is common.
