The SOCATA TBM 700 (also marketed as the TBM 850, Daher TBM 900, Daher TBM 910 and Daher TBM 930) is a high performance single-engine turboprop light business and utility aircraft manufactured by DAHER-SOCATA. An aerodynamically refined version of the TBM 700N is marketed as the TBM 900 from March 2014.[3]

Design and development[edit]

In the early 1980s, the Mooney Airplane Company of Kerrville, Texas designed a six-seat pressurised light aircraft powered by a single 360 hp (268 kW) piston engine, the Mooney 301, which made its maiden flight on 7 April 1983.[4] Mooney was purchased by French owners in 1985,[5]:443 which resulted in talks between Mooney and the French company SOCATA to build a turboprop derivative of the 301. The result of these discussions was the TBM 700, which was much heavier than the 301 with more than twice the power, with a joint venture, TBM International, being set up in June 1987 between Mooney and Socata's parent company Aérospatiale to design and build the new aircraft.[4][5]:135 In the designation TBM, "TB" stands for Tarbes, the French city in which Socata is located, the "M" stands for Mooney.[4]

The TBM 700 is a single-engined turboprop, six to seven-seat low-wing monoplane of mainly aluminium and steel construction, but with the tail surfaces built of Nomex honeycomb. It has a retractable tricycle landing gear and is powered by a Pratt & Whitney Canada PT6A-64 engine delivering 700 shp (522 kW).[4][6] The first prototype TBM 700 made its maiden flight on 14 July 1988,[5]:135 with French certification following on 31 January 1990 and US FAA certification achieved on 28 August 1990.[4]

Two production lines were planned, one at Kerrville to cater to the American market, and the other at SOCATA's factory in Tarbes to build aircraft for the rest of the world. A shortage of money resulted in Mooney withdrawing from the project in May 1991.[4] The TBM 700 also comes in a cargo variant.

The TBM 850 is the production name for the TBM 700N, an improved version with the more powerful Pratt & Whitney PT6A-66D engine flat rated at 850 shp (634 kW). The TBM 850 is limited to 700 shp (522 kW) for takeoff and landing, but in cruise flight the engine power can be increased to 850 shp (634 kW). This extra power gives it a higher cruising speed than the TBM 700 models, especially at high altitudes (due to the flat-rating). The outside appearance of the TBM 850 has remained the same as that of the TBM 700. The TBM 850 has a typical range of 1,520 nautical miles (2,820 km).

Beginning with the 2008 model, the TBM 850 is equipped with the Garmin G1000 integrated flight deck as standard equipment.[7]

Introduced in 2014, the TBM 900 is an improved version with 26 modifications including winglets, a redesigned air intake and a 5-blade propeller, for better aerodynamics and performance.[8]

Variants[edit]

TBM 900
A TBM 900 with a five-blade propeller
Improved version of the TBM 850 with various aerodynamic refinements, including winglets and a redesigned induction system.[10] Maximum cruise speed increased to 330 kn at FL310. Range of 1,730 nmi (with 45-minute standard IFR reserves) at 252 kn and 37 gph, or 1,585 nmi at 290 kn.[8] The previously optional Hartzell five-blade carbon fiber propeller is now standard, increasing performance and decreasing cabin noise.
TBM 910
New version introduced in April 2017, with the upgraded avionics suite Garmin G1000 NXi.[11]
TBM 930
New version introduced in April 2016, with upgraded interior and avionics, including the Garmin G3000 touchscreen avionics suite. The TBM 930 is offered alongside the 900 and has not replaced it in the line-up.[12][13]

Production[edit]

At the end of 2016, the TBM fleet had logged a combined 1.4 million flight hours and 822 aircraft had been produced.[1]

  • TBM 700 - 324 built between 1990-2005
  • TBM 850 - 338 built between 2006-2013
  • TBM 900 - 106 built since 2014

Accidents and incidents[edit]

On 5 September 2014, a TBM 900 (registered N900KN) was found to be flying with an apparently unconscious pilot over South Carolina in the eastern United States. Pilots of fighter aircraft that were scrambled to trail the TBM 900 observed that the windows were frosted over. The aircraft reportedly crashed in the sea 14 miles northeast of Portland Parish, Jamaica, on the country's northeast coast.[15][16]
