The TBM-700 is a high performance single engine turboprop powered light business and corporate transport.
The TBM-700 is mainly optimised as a business transport in competition with established twin turboprops, mainly Beech's C90 King Air series. Unlike the similarly sized C90 King Airs though, the TBM-700's single engine layout is a major conceptual difference. With its single PT6 turboprop, rather than two on the King Air, the TBM-700 offers significantly lower operating costs yet comparable performance.
he SOCATA TBM 700 and TBM 850 are high performance single engine turboprop light business and utility aircraft manufactured by SOCATA. The TBM 700 was offered until 2006, when the TBM 850 was introduced.
HISTORY
The TBM-700 was originally developed in partnership between Socata (Aerospatiale's General Aviation division) in France and Mooney in the USA, hence the TBM designation. The two companies formed TBM SA to build and market the TBM-700, with development responsibility for the project divided on a 70/30 basis between Socata and Mooney respectively.
The first of three TBM-700 prototypes first flew on July 14 1988. French certification was granted in January 1990. Shortly after the delivery of the first production aircraft in December 1990, Mooney withdrew from the program, leaving Socata with full responsibility for the aircraft.
DESIGN AND DEVELOPMENT
The TBM 700 is a single turboprop engined, 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).The first prototype TBM 700 made its maiden flight on 14 July 1988,[3] with French certification following on 31 January 1990 and US Federal Aviation Administration (FAA) certification achieved on 28 August 1990.
It was planned that two production lines be set up, one at Kerrville to cater for the American market and the other at Socata's factory at Tarbes to build aircraft for the rest of the world. A shortage of money resulted in Mooney withdrawing from the project in May 1991.The TBM 700 also comes in a cargo variant.
