The Pinaire Ultra-Aire is an American ultralight aircraft that was designed and produced by Pinaire Engineering. The aircraft was supplied as a kit for amateur construction.[1][2]

Design and development[edit]

The aircraft was designed to comply with the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of 254 lb (115 kg). The aircraft has a standard empty weight of 252 lb (114 kg). It features a cable-braced high-wing, canard elevator, a single-seat, open cockpit, tricycle landing gear and a single engine in pusher configuration.[1][2]

The aircraft is made from bolted-together aluminum tubing, with its flying surfaces covered in Dacron sailcloth. Its compact single-surface 26 ft (7.9 m) span wing is supported by cables attached to a simple tube kingpost. The pilot is accommodated on a suspended sling seat. The control system is two-axis with pitch controlled by a canard elevator attached to the side-stick. Roll and yaw are controlled by wing tip rudders also controlled by the side-stick. The landing gear features a steerable nose wheel, also controlled by the side-stick. The standard engine supplied with the kit was the Cuyuna UL II-02 twin cylinder, two-stroke powerplant of 35 hp (26 kW).[1][2]

The aircraft was carefully tested using sandbag loading to +6 and -4 g without failure. Reviewer Andre Cliche describes the design as "well engineered". The Ultra-Aire can be quickly dismantled for ground transportation or storage.[1]
