Norman BN-2A Mk III Trislander
Manufactured 1970–1982
First flight 11 September 1970
The Britten-Norman Trislander (more formally designated the BN-2A Mk III Trislander) is a three-engined piston-powered utility aircraft designed and produced by the British aircraft manufacturer Britten-Norman.
The Trislander was designed in the late 1960s as an expanded derivative of the company's Islander, a twin-engined commercial aircraft that had proved to be a commercial success. In comparison to its predecessor, it had a larger carrying capacity, being capable of seating up to 18 passengers, and could also perform STOL operations when required.[1] On 11 September 1970, the prototype Trislander performed its maiden flight; the type entered revenue service less than a year later.
Design and development
During the 1960s, the British aircraft manufacturer Britten-Norman, founded by John Britten and Desmond Norman, had designed and commenced production of the Islander, a twin-engined commercial aircraft that quickly proved itself to be a commercial success. Being keen to capitalise on the Islander, the company's management opted to pursue development of a larger aircraft that would be derived from its predecessor as to benefit from commonalities and to lower development costs. In 1968, the company flew a stretched variant of the aircraft, known as the BN-2E Islander Super, however, this model was never pursued through to certification in favour of a more radical alternative design - the Trislander.

Seeking to give the aircraft a considerably larger carrying capacity, the Islander's fuselage was stretched and strengthened considerably for the Trislander, a measure that necessitated various configuration changes The most visually apparent of these was the addition of a third engine located on the fuselage centre line atop an elongated tailfin.[A fixed tricycle landing gear arrangement was also adopted. While possessing an unorthodox appearance, the arrangement proved practical; in terms of construction, the Trislander was similar enough to the Islander that the two aircraft shared the same final assembly line

n terms of its flying characteristics, the Trislander possesses exceptional low speed handling characteristics, extended endurance, increased payload, and a relatively low noise signature. Capable of taking off from a 150 metres (492 ft) long landing strip, the Trislander can readily operate from unprepared surfaces.
