The Bede BD-12 was an American homebuilt aircraft designed by Jim Bede and produced by Bede Aircraft of Medina, Ohio, introduced in the 1990s. The aircraft was intended to be supplied as a kit for amateur construction, but only one was ever built.[1][2] It first flew in 1995.[3]

Design and development

Designed as a scaled-up Bede BD-5, the BD-12 featured a cantilever low-wing, a two-seats-in-side-by-side configuration enclosed cockpit under a gull-wing canopy, retractable tricycle landing gear and a single engine in pusher configuration.[1]

The aircraft was made from fibre-reinforced plastic composite materials. Its 23.0 ft (7.0 m) span wing, mounted flaps and had a wing area of 93.0 sq ft (8.64 m2). The standard engines used were the 100 hp (75 kW) Continental O-200A or the 150 hp (112 kW) Lycoming O-320 powerplant.[1]

The aircraft had a typical empty weight of 680 lb (310 kg) and a gross weight of 1,310 lb (590 kg), giving a useful load of 630 lb (290 kg). With full fuel of 37 U.S. gallons (140 L; 31 imp gal) the payload for the pilot, passenger and baggage was 408 lb (185 kg).[1]

The standard day, sea level, no wind, takeoff with a 150 hp (112 kW) engine was 725 ft (221 m) and the landing roll was 800 ft (244 m).[1]

The company that currently owns the rights to the design, BedeCorp, indicates that production was not started due to the cost of tooling and the lack of funds.[2]

The design was further developed into the Bede BD-14, a four-seat version.[1][2]

Operational history

In April 2015 no examples were registered in the United States with the Federal Aviation Administration, although one had been registered to the designer at one time.[4]
