Britten-Norman Islander BN-2B Islander II

By 1978 the Islander had been in production for a decade and the problem was no longer selling the concept but keeping it competitive. The BN-2B was the answer: a product improvement programme that touched neither the aerodynamics nor the basic powerplant, only what operators complained about. The flight deck was redesigned, maximum landing weight rose and cabin noise fell, partly through smaller-diameter propellers. Nothing spectacular on paper; enough for the aircraft to keep selling for another thirty years.

The BN-2B's numbers describe well what Britten-Norman had been after from the start. At under eleven metres long and just under fifteen in span, the twin carries one pilot and nine passengers at a maximum take-off weight of 2,994 kg, and does so at little more than two hundred and forty kilometres per hour in cruise. Speed was never the argument: the argument was payload per pound of engine, the short unprepared strip, and a structure designed to work at low stress levels with an indefinite fatigue life.

That structural longevity became the manufacturer's own worst commercial rival. Sales fell away from the 1980s onwards, and company management put it down to a market saturated by its own aeroplanes: Islanders in service did not fall out of the sky, and an island operator rarely has reason to replace one that still flies. The result is a worldwide fleet counted in the hundreds and a production line that returned to the Isle of Wight in 2023 after more than half a century of manufacture abroad.
