Rutan Aircraft Factory Long-Ez

Single Piston

The Rutan Long-EZ is one of the most successful homebuilt aircraft designs in aviation history, a tandem two-seat canard pusher that defined efficient cross-country flying for amateur builders. Designed by Burt Rutan and introduced in 1979, the Long-EZ combined radical aerodynamics with practical performance: cruise speeds of 160-180 knots on just 100-115 horsepower, fuel economy exceeding 40 miles per gallon, and a range approaching 1,600 nautical miles. Its distinctive canard configuration, with the horizontal stabilizer ahead of the wing, provided natural stall resistance and docile handling, while the composite construction from fiberglass and foam made it both lightweight and strong. The Long-EZ became the template for thousands of homebuilts worldwide, proving that amateur constructors could achieve airline-like efficiency in a two-seater. Over 700 Long-EZs have been completed since the plans were released, with many still flying decades later. The type's high-altitude capability (service ceiling around 27,000 feet) and slippery aerodynamics made it a favorite for record attempts and long-distance flights, including multiple ocean crossings. SkyMeter has tracked flights across airframes and operators, with the largest observed operator.

Safety in context

The incident rate counts flights with ANY safety event detected by SkyMeter: go-arounds (a routine response, not a failure), unstable-approach gate flags (advisory thresholds), rejected takeoffs (the system working as designed), and runway events. It is NOT an accident rate or fatality rate. For accident statistics, refer to the NTSB Aviation Accident Database (USA) or the Aviation Safety Network. See methodology for what each event type measures.
