Design and development
The AC4 was designed to comply with the Fédération Aéronautique Internationale microlight rules and US light-sport aircraft rules. It features a strut-braced high-wing, with "V"-struts and jury struts, a two-seats-in-side-by-side configuration enclosed cockpit, fixed tricycle landing gear and a single engine in tractor configuration.
The aircraft is made from a combination of composites and aluminum sheet, with its tailboom made from a single large diameter aluminium tube and the wings and tail surfaces covered in aluminium. Its {{convert|9.45|m|ft|1|abbr=on}} span wing has an area of {{convert|16.65|m2|sqft|abbr=on}}, is supported by V-struts and mounts flaps. The standard engine available is the {{convert|100|hp|kW|0|abbr=on}} Rotax 912ULS or Rotax 912iS four-stroke powerplant.{{cite web|url=http://www.lightwing.ch/index.php?id=40&L=1|title=Lightwing AC4|author=Light Wing AG|work=lightwing.ch|access-date=27 August 2016}}
The AC4 can accommodate one pilot and one passenger and was also designed for aero-towing gliders. It can also accommodate a stretcher for Medevac missions. It received European European Aviation Safety Agency type certification to the Certification Specification for Light Sport Aeroplanes (CS-LSA) on 6 August 2015.{{cite book |title=TYPE-CERTIFICATE DATA SHEET EASA.A.588 for LIGHTWING AC4 |date=6 August 2015 |publisher=EASA |url=http://www.lightwing.ch/fileadmin/documents/Factsheets/EASA-TCDS-A588_ADxC_LightWing_AC4_issue3.pdf|access-date=12 February 2019}}
