GippsAero GA8 Airvan

The GA8 was conceived to address a perceived gap in the market between the Cessna 206 and the Cessna 208 Caravan. Designed primarily by Peter Furlong, the aircraft was engineered to meet the stringent Part 23 requirements of the FAA, which involved rigorous dynamic testing and validation of controllability following the failure of any primary flight control. The GA8 received its type certification in 2004 and its first flight took place on 3 March 1995. Development continued with a turbocharged version, designated the GA8-TC320, which commenced flight testing in October 2006 and was certified in February 2009, featuring a 320 HP Lycoming TIO-540-AH1A engine.

The GA8 is designed as an eight-seat utility aircraft with a configuration similar to the Cessna 208 Caravan, featuring a rectangular fuselage. Each passenger benefits from rectangular windows bulged outwards to enhance downward visibility, while the high wing positioned aft of the pilot improves upward visibility. The aircraft includes an aisle between the seats, evenly distributed cabin ventilation, and modular upholstery for rapid replacement. Designed for ease of maintenance with minimal tooling and maximized accessibility, the cabin rear door can be opened mid-flight. The airframe and onboard systems are designed for durability and simplicity, featuring a spring-suspended tricycle undercarriage that is oil-free, and the wing tanks feed a single sump tank under the cabin floor, eliminating the need for fuel selectors. The simple wing has mechanically actuated flaps, with the wings rated for 92,000 hours. Avionics include a Garmin G500 multi-function display, Garmin GTN750 and 650 touchscreen satellite navigation units, and backup analog instruments.

The GA8 Airvan, while primarily a utility aircraft, can be configured to carry various payloads depending on its mission. Dedicated configurations are available for skydiving, freight, and intelligence, surveillance, and reconnaissance (ISR) missions. For freight operations, the GA8 can carry up to 440 lb (200 kg) within an optional cargo pod accessible through a side door and rear-mounted hatch. For ISR missions, multiple sensors, such as a Wescam-supplied surveillance camera, can be contained in a modular pod, and mission workstations secured to standard seat mounts for up to three operators. These sensors can be retractable to appear as an ordinary cargo pod.

The GA8 Airvan has seen diverse operational use since its introduction, serving in roles such as passenger services, freight transport, sightseeing, parachuting, observation, and search and rescue operations, often in remote and austere environments. Civil operators, including air charter companies and skydiving businesses, have utilized the aircraft. Entities like the Civil Air Patrol (CAP) once operated a fleet of 18 Airvans for search and rescue, disaster response, and damage assessment missions, though these are being phased out as of 2022. The Mission Aviation Fellowship utilizes the GA8 to provide air transport services in developing countries, with operations in Australia and Suriname. The Lesotho Defence Force represents one known military operator of the type.
