# Adventure Air Adventurer

The Adventure Air Adventurer is a family of American homebuilt amphibious flying boats that was designed and produced by Adventure Air of Berryville, Arkansas. When it was available the aircraft was supplied as a kit for amateur construction. The company appears to be out of business.

## Design and development

The aircraft features a strut-braced high-wing, a four-seat enclosed cockpit, retractable tricycle landing gear, a boat hull with outrigger pontoons, a cruciform tail and a pod-mounted single engine in pusher configuration.
The airframe is made from composites. Its 35.85 ft (10.9 m) span wing mounts flaps and has a wing area of 179.00 sq ft (16.630 m$^2$). The cabin is 46 in (120 cm) wide. The recommended engines vary by model. The factory available options included wing tanks of 60 U.S. gallons (230 L; 50 imp gal), 120 U.S. gallons (450 L; 100 imp gal) or 180 U.S. gallons (680 L; 150 imp gal), dual controls and a pre-assembled wing.
The factory estimated the construction time from the supplied standard kit as 1000 hours, or 400–600 hours from the quick-build kit.

## Operational history

By 1998 the company reported that 120 kits had been sold and five aircraft were flying.
By November 2013 ten examples had been registered in the United States with the Federal Aviation Administration.
