The Islander’s simple design lends itself to easy reconfiguration between  a wide variety of roles.

Executive, commuter, freight and special mission fit options (including air ambulance, parachuting, crop spraying and aerial survey) are all readily available as standard.

In 1963, the firm initiated development work upon what would become the Islander, having sensed a demand for a single and inexpensive twin-piston engine aircraft.

In 1970, a military version of the Islander, marketed as the Defender, conducted its first flight. Modifications included the addition of underwing hardpoints for armaments/equipment, and the main cabin area being fitted out for light troop transport and support aircraft duties. The Defender capitalised on the aircraft’s rugged structure, making it suitable for long-term operations in developing countries. Purchases from police and military customers have typically been for use in surveillance and counter-terrorism operations. The Maritime Defender is another military version of the Islander, intended for search and rescue, coastal patrol and fishery protection.

Aircraft of similar role, configuration and era are: Cessna 402, Cessna 208 Caravan, Dornier Do 28, GippsAero GA8 Airvan, Piper PA-31 Navajo, Tecnam P2012 Traveller.
