Alpi Aviation Alpi Pioneer 400
Single Piston
The Alpi Pioneer 400 is an Italian-designed two-seat light sport aircraft and ultralight kit plane manufactured by Alpi Aviation of Pordenone. First flown in the early 2000s, the Pioneer 400 represents a modern approach to affordable recreational aviation, combining composite construction with conventional high-wing configuration and tricycle landing gear. The aircraft is certified under European CS-VLA (Very Light Aircraft) standards and qualifies as a Special Light-Sport Aircraft in the United States, making it accessible to sport pilot certificate holders. Powered by a single Rotax 912-series engine producing 80-100 horsepower, the Pioneer 400 cruises at approximately 108 knots and offers a useful load around 485 pounds, suitable for two occupants and modest baggage on flights up to 500 nautical miles. Its composite airframe keeps empty weight near 650 pounds while providing a relatively spacious cabin for the ultralight category. The type appeals to owner-builders seeking a capable cross-country tourer that remains within light sport limitations, and its kit format allows builders to customize avionics and interior appointments. SkyMeter has tracked flights across airframes and operators, with distinct routes observed.
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.
