The aircraft was introduced to the public at AirVenture 2012.
Design and development
The Bearhawk LSA is a "clean sheet design" inspired by the larger Bearhawk Patrol. The LSA features a strut-braced high-wing, a tandem enclosed cockpit accessed by a single right-side door, fixed conventional landing gear and a single engine in tractor configuration. The cockpit is {{convert|31|in|cm|0|abbr=on}} wide. In 2015 a quick-build kit was introduced at the U.S Sport Aviation Expo.{{cite journal|journal=Sport Aviation|date=March 2015|page=15|title=Briefly Noted}}
The aircraft fuselage is fabricated from welded 4130 steel tubing covered in heat-shrunk aircraft fabric. The aluminum structure wing, covered in flush riveted aluminum sheet, employs a Harry Riblett-designed GA30-613.5 airfoil and does not have flaps. The wing is supported by a single strut per side. Recommended engines include the {{convert|65|hp|kW|0|abbr=on}} Continental A-65, {{convert|75|hp|kW|0|abbr=on}} Continental A-75 and the {{convert|100-110|hp|kW|0|abbr=on}} Continental O-200 four-stroke power plants.{{Cite web|url=http://www.bearhawkaircraft.com/LSA/Photos/LSA_spec_sheet.jpg|archive-url=https://web.archive.org/web/20131215224828/http://bearhawkaircraft.com/LSA/Photos/LSA_spec_sheet.jpg|url-status=dead|archive-date=15 December 2013|title=Specifications|accessdate=20 November 2012|last=Barrows|first=Bob|year=2012}}{{cite web|url=http://registry.faa.gov/aircraftinquiry/NNum_Results.aspx?NNumbertxt=289eh|title=Registration Inquiry Results-N289EH|accessdate=20 November 2012|last=Federal Aviation Administration|date=20 November 2012}} However, many other engine options are available including Lycoming, Corvair, ULPower, and Rotax with many exceeding 110 hp.
The aircraft was designed for a maximum gross weight of {{convert|1500|lb|kg|abbr=on}} in the utility category, but is limited to {{convert|1320|lb|kg|abbr=on}} in the US light-sport aircraft category.
