The SOCATA TB-21 Trinidad is an all-metal low-wing, four or five seat light cabin aircraft, fitted with retractable tricycle landing gear,
driven by a three-bladed constant speed propeller, powered by a single 250 hp turbocharged engine. In 1975, SOCATA (Société de Construction
d'Avions de Tourisme et d'Affaires) started the development of a new light aircraft to replace the ageing Rallye. A universal low-wing
four-seat airframe was chosen to be the basic of a new light aircraft line. The prototype, designated SOCATA TB-10 flew first on 10 February 1977.
Three development aeroplanes followed this prototype "F-WJZP". Deliveries of the production TB-10 Tobago planes, initially powered by
a 180 hp Lycoming O-360-A1AD engine, started in 1979. Next to the TB-10 Tobago the airframe was the base of a family of light aircraft, starting
in 1980 with the TB-9 Tampico followed later that year by the TB-20 Trinidad, that was first flew on 14 November 1980. The TB-21 Trinidad TC was
a turbo-normalised TB-20 and has a higher operating ceiling and climbs through airway levels a lot faster. More than 2.150 TB-type
aircraft have entered service worldwide.
The ICAO code of the SOCATA TB-21 Trinidad TC was TRIN, this code was deleted from ICAO Document 8643
in 2014 and replaced by TB21 |
