The three engined Trislander takes its motivation from the arrangements of trijets, for example, the L-1011 and DC-10 in its response to the requirement for more power for an extended adaptation of the Islander (depicted independently).

Britten-Norman exploration demonstrated that there existed sufficient business interest to warrant the advancement of an extended Islander, and the organization presumed that any extended variant would need to offer a half build in interior limit. The organization's novel methodology to the requirement for more power was to include a third motor, as opposed to two motors of expanded force yield. A nose mounted motor in the manner of the Ju-52 was viewed as, however because of the Islander's nose design, Brittennorman settled on mounting the motor on the vertical tail, bringing about the BN-2a Mk.3 Trislander.

The tail mounted motor included noteworthy change to the tail and reinforcing of the back fuselage. Different changes over the Islander incorporate a 2.29m (7ft 6in) fuselage extend forward of the wing, new fundamental arriving apparatus and bigger breadth wheels and tires.

The main Trislander was actually changed over from the second Islander model, and it made the sort's first flight on September 11 1970. Early creation Trislanders were additionally changes of Islanders, while ensuing Trislanders were based on the same generation line as the Islander. The primary creation Trislander flew on March 6 1971, affirmation was allowed on May 14, and first conveyances to a client happened on June 29 that year.

Britten-Norman Trislander creation stopped in 1982 after 73 were requested (by which arrange the organization had been procured by Pilatus). Arrangements to create the Trislander in the USA as the Tricommutair by the International Aviation Corporation, and in Australia never worked out as expected. However one of 12 units manufactured for the Tricommutair undertaking was amassed in Guernsey in the UK and flew in March 1996.
