Dyn'Aéro Mcr-01

Single Piston

The Dyn'Aéro MCR-01 is a French-designed ultralight aircraft that occupies a niche between traditional ultralights and certified light sport aircraft. Built by Dyn'Aéro in Darois, France since the late 1990s, the MCR-01 (Micro Course de Raid) is a sleek, low-wing two-seater known for its composite construction and efficient aerodynamics. The design emphasizes cross-country performance in the ultralight category, with a cruise speed around 120 knots and respectable range for an aircraft weighing just 450 kilograms maximum takeoff weight. Its clean lines and retractable landing gear give it a miniature sportplane appearance, and it has found favor among European pilots seeking economical touring capability without the regulatory burden of certified aircraft. The type is particularly popular in France and Germany, where ultralight regulations permit operation with simplified licensing. 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.
