Listed as "under development" in 1998, the YT-33 was planned to be supplied as a kit for amateur construction, but it is unlikely any kits were ever shipped.[1]

Design and development

The YT-33 features a cantilever low-wing, a two-seats-in-tandem enclosed cockpit under a bubble canopy, retractable tricycle landing gear and a single jet engine.[1]

The aircraft is made from composite material. Its 26.67 ft (8.1 m) span wing has a wing area of 110.0 sq ft (10.22 m2). The prototype uses a 880 lb (400 kg) thrust Turbomeca Marboré IIC jet powerplant.[1][2]

The aircraft has a typical empty weight of 2,205 lb (1,000 kg) and a gross weight of 2,920 lb (1,320 kg), giving a useful load of 715 lb (324 kg). The aircraft has a fuel capacity of 200 U.S. gallons (760 L; 170 imp gal) or 1,358 lb (616 kg) of Jet-A.[1]

The standard day, sea level, no wind, take off distance is 2,000 ft (610 m) and the landing roll is 3,000 ft (914 m).[1]

The manufacturer estimated the construction time from the proposed kit to be 3000 hours.[1]

Operational history

By 1998 the company reported that one aircraft had been completed and was flying.[1]

On 18 April 2018 the one example that had been registered in the United States with the Federal Aviation Administration was de-registered and the aircraft may not exist any more.[2]
