homebuilt aircraft Homebuilt aircraft, also known as amateur-built aircraft or kit planes, are constructed by persons for whom this is not a professional activity. These aircraft may be constructed from "scratch", from plans, or from assembly kits.Armstrong, Kenn ...

for cross-country flights, the first of the kit built prototypes was first flown on 28 July 1987, a factory built aircraft first flew in 1990. Wheeler Technology went into bankruptcy and the assets were bought by Express Design Incorporated (EDI) of Redmond, Oregon. Kits that were under construction were completed by EDI and they continued with kit production. A six-seat variant was produced by EDI as the Loadmaster 3200. EDI closed its doors and disconnected telephone lines after it filed for Chapter 7 bankruptcy on 6 January 1996. In 1997, Paul Fagerstrom of Express Aircraft Company, LLC (EAC) purchased rights to the Express

was chosen to reduce the number of stiffeners and stringers needed. The design used an unusual seating position where one rear seat faced forward and one aft to maximize interior space. The fuselage was built with similar construction methods to Glasair aircraft with a Cruciform tail. The aircraft was only produced in kit form with five main packages that included pre-cut ribs, pre-welded steel assemblies, and a spar prebonded to the upper wing surface. The cabin width is .

Operational history

A crash of an early example of the Wheeler Express was said to demonstrate the airframe's safety due to the energy absorption during the non-fatal crash. Although the airframe is touted as being structurally sound, the National Transportation Safety Board issued a July 2015 report in which it cited pilot error and aircraft design, specifically the cruciform tail’s yaw stability, as a possible culprit to a fatal Wheeler Express accident in which the pilot failed to maintain airspeed during a maneuver resulting in a stall. All three lives were lost. Critics and Wheeler Express pilots argue that the loss of control was simply pilot error and that any plane involved in a high-angle steep turn would experience a stall below Vs, or stall speed.
