worth £126 million for the provision of 130 aircraft, along with an option for a further 15; this option was never taken up. The first flight of the prototype EMB-312G2, which was furnished with a four-bladed Hartzell propeller and the Garrett TPE331-10 engine, took place in Brazil on 14 February of the following year. Shortly afterwards, this aircraft was disassembled and airlifted to Short's Belfast facility on 29 March 1986, where it was reassembled and returned to the skies just ten days later. During June of that year, the TPE331-10 engine was replaced by the improved TPE331-12B, a major difference being the integration of an Electronic Engine Controller (EEC) system. Production On 30 December 1986, the first standard production model Tucano T.Mk 1 was flown; its official rollout took place on 20 January 1987. On 10 March 1987, the second aircraft made its first flight, and, by April, a third Tucano had joined the test fleet for clearance and final testing, which was largely undertaken at MOD Boscombe Down. The fourth aircraft to be built was the first delivered to the RAF on 16 June 1988 at the Central Flying School. Deliveries would continue to the RAF for another five years, the final aircraft arriving on 25 January 1993. In addition to the sizable order for the RAF, multiple export customers emerged for the Shorts-produced Tucanos. The Kenyan Air Force ordered a total of 12 units while a further 16 Tucanos were exported to Kuwait. Those Tucanos delivered to the Kuwait Air Force were suitable furnished to be combat-capable, it was armed for the purposes of both weapons training and light attack duties; such aircraft are fitted with four hard points, each capable of mounting various rocket pods, cannons, bombs, and external fuel tanks. Due to its Garrett engine, the Short Tucano is more responsive to thrust changes and is somewhat noisier than the original Tucano. In addition to the revised engine, the major differences of the Short Tucano are a strengthened airframe for an improved fatigue life, a cockpit layout similar to the RAF's Hawk advanced trainer, a revised oxygen system, a flight data recorder, a four-bladed propeller, ventral airbrake and restyled wingtips. Two Martin-Baker MB 8LC ejection seats are used and the canopy was modified to meet the RAF's bird strike requirements. During its production run, Shorts commonly promoted the airframe as being "100% British-built". In order to
