Design and development Edit

The aircraft is produced by Airmak S.r.l., a joint venture between Rafaelle Violetti and Valter Proietti of OMA Sud. It is manufactured at OMA Sud's Italian facility. Production commenced in the middle of 2012.[1][2]

The J4 was designed to comply with the Fédération Aéronautique Internationale microlight rules and US light-sport aircraft rules. It features a strut-braced high-wing, a two-seats-in-side-by-side configuration enclosed cabin accessed by doors, fixed tricycle landing gear and a single engine in tractor configuration.[1]

The aircraft fuselage is made from welded steel tubing, with riveted aluminium tail and wings. Its 9.44 m (31.0 ft) span wing has an area of 11.6 m2 (125 sq ft), employs a custom Iannotta airfoil and mounts flaps. The standard engine used is the 100 hp (75 kW) Rotax 912ULS four-stroke powerplant.[1][3]

As of January 2017 the design does not appear on the Federal Aviation Administration's list of approved special light-sport aircraft.[4]

Operational history Edit

Reviewer Marino Boric described the design in a 2015 review as "elegant".[1]
