The Britten-Norman Trislander is a stretched, three-engine development of the BN-2 Islander, designed to offer greater passenger capacity on short-haul and inter-island routes. It was developed by Britten-Norman and entered service in the early 1970s, featuring an unusual configuration with a third engine mounted at the base of the vertical tail fin. The aircraft seats up to 17 passengers and is optimized for operations from short, unprepared airstrips. Its simple, robust construction and low operating costs made it attractive to small regional and island operators worldwide. Production was limited, with just over 70 aircraft built. While most have been retired, a small number remain in service with niche operators, particularly in the Caribbean and other island regions.
Notable operators
Aurigny Air Services was a prominent operator, along with various Caribbean and Pacific island carriers.
