The Frontier MD-II was an American homebuilt aircraft that was designed and supplied as a kit by Frontier Aircraft Inc of Vail, Colorado, introduced in the 1990s.[1]

Design and development[edit]

The MD-II featured a strut-braced high-wing, a two-seats-in-side-by-side configuration enclosed cockpit accessed via doors, fixed conventional landing gear with wheel pants and a single tractor engine.[1]

The aircraft was fabricated from 2024-T3 aluminum sheet. Its 29.50 ft (9.0 m) span wing employed a USA 35B airfoil, mounted flaps and had an area of 177.0 sq ft (16.44 m2). The cabin width was 41 in (100 cm). The acceptable power range was 65 to 200 hp (48 to 149 kW) and the standard powerplant used was the 140 hp (104 kW) Avia M 332 (LOM) four cylinder, inverted, air-cooled, supercharged, inline aircraft engine.[1]

With the Avia engine the MD-II had a typical empty weight of 1,150 lb (520 kg) and a gross weight of 2,000 lb (910 kg), giving a useful load of 850 lb (390 kg). With full fuel of 43 U.S. gallons (160 L; 36 imp gal) the payload for pilot, passenger and baggage was 592 lb (269 kg).[1]

The manufacturer estimated the construction time from the supplied kit at 1500 hours.[1]

Operational history[edit]

By 1998, the company reported two kits had been sold with two aircraft complete and flying.[1]

In December 2013, no examples were registered with the US Federal Aviation Administration.[2]
