Development and Design Philosophy
Eagle Aviation LLC conceived the EA-100 during the mid-2000s boom in light-sport aviation, targeting pilots seeking an affordable yet capable aircraft for personal transportation and training applications. The company established operations in Oshkosh, Wisconsin—the heart of American experimental aviation—positioning itself strategically within the homebuilt aircraft community that gathers annually for the EAA AirVenture convention.
The EA-100's design emphasized practicality over innovation, featuring conventional all-metal construction that appealed to builders familiar with traditional aircraft assembly techniques. Engineers specified aircraft-grade fasteners throughout the airframe and applied zinc-chromate treatment to prevent corrosion, ensuring longevity in diverse operating environments.
Engine Options and Performance
Eagle Aviation offered multiple powerplant configurations to accommodate varying pilot preferences and mission requirements. The standard production engine became the RAM 115, a fuel-injected unit producing 115 horsepower at 5,000 RPM while generating 130 foot-pounds of torque at 3,100 RPM. This engine utilized a modified Subaru E81 automotive block with 1,781 cc displacement, liquid cooling, and direct-fire CDI ignition.
Alternative engine choices included the Rotax 914 turbocharged four-cylinder producing 115 horsepower, the naturally aspirated Rotax 912ULS, and the Subaru 115FL. The RAM 115's 2,000-hour time between overhauls provided operators with reasonable maintenance intervals, while its automotive heritage promised parts availability and lower operating costs compared to traditional aircraft engines.
Flight Characteristics and Capabilities
With its 1,320-pound maximum takeoff weight, the EA-100 operated within light-sport aircraft limitations while delivering respectable performance figures. The aircraft demonstrated a 244 feet-per-minute climb rate and reached a service ceiling of 13,500 feet, adequate for cross-country touring in most geographic regions.
Pilots appreciated the EA-100's benign handling characteristics, with stall speeds of 49 mph in clean configuration and 40 mph with flaps extended. These low approach speeds made the aircraft suitable for operations from shorter airstrips, while takeoff and landing runs of 492 feet and 459 feet respectively provided access to numerous general aviation facilities.
The 121-liter fuel capacity enabled a maximum range of 622 miles at cruise power settings, positioning the EA-100 as a legitimate cross-country traveler despite its light-sport classification. Pilots could carry 585 pounds of useful load, accommodating two occupants plus 66 pounds of baggage for weekend excursions.
Production and Market Response
Eagle Aviation primarily marketed the EA-100 as a kit aircraft, capitalizing on the cost savings and personal satisfaction associated with homebuilt construction. The prototype's initial flight in 2007 demonstrated the design's viability, leading to kit deliveries throughout the United States amateur-built market.
International interest emerged when Hangar 1 Aircraft Sales imported the first EA-100 kit to Australia in early 2009, suggesting global appeal for the American design. However, specific production numbers remain undocumented, indicating relatively limited market penetration compared to established competitors in the light-sport segment.
Manufacturer Background
Eagle Aviation LLC operated from W635A 20th Avenue in Oshkosh, maintaining proximity to EAA headquarters and the annual AirVenture gathering that serves as the industry's primary marketing venue. The company's location provided access to a concentrated pool of aviation expertise and potential customers familiar with experimental aircraft construction.
Despite its strategic positioning and competent product offering, Eagle Aviation failed to achieve the market prominence of competitors like Van's Aircraft or Kitfox. The company's current operational status remains unclear, with limited public information available regarding ongoing production or support activities.
Legacy and Current Status
The EA-100 represents the challenges facing smaller kit aircraft manufacturers in an increasingly competitive market. While technically competent and offering reasonable performance, the aircraft entered a crowded field dominated by established designs with proven track records and extensive builder support networks.
Today, EA-100 examples likely remain in service with their original builders and subsequent owners, though comprehensive fleet statistics are unavailable. The aircraft's conventional construction and standard powerplant options should facilitate ongoing maintenance, assuming parts availability for critical components.
The EA-100's story reflects broader trends in general aviation, where innovative smaller companies often struggle to achieve sustainable market share despite producing capable aircraft that meet genuine pilot needs.
