The plane only traveled three hundred meters before crashing after taking off from the aerodrome near Nancy (Meurthe-et-Moselle), Sunday June 28, 2026. The eleven people on board, a pilot, five instructors and five passengers who had come to do a parachute jump baptism died. Ten days earlier, a Cessna 421 leaving Rennes crashed on approach to La Baule, killing its two occupants including Claude Guillemot, co-founder of Ubisoft. Enough to once again raise the question of the safety of these small planes: are they structurally more dangerous than larger ones?
The available data answer “yes” without discussion. In France, commercial air transport, with planes of more than 19 passengers, has not recorded any fatal accidents in 2024, recalls the latest annual report on aviation safety. The rate of fatal accidents per million flight hours has remained at zero since 2014.
Conversely, light aviation, private flights, microlights, gliders, was responsible in France for 13 fatal accidents causing 23 victims. Over ten years, between 2015 and 2024, the cumulative toll of light aviation reaches 153 fatal accidents for microlights, and 70 for light aircraft. These figures are relatively stable from one year to the next.
Device design and maintenance
An airliner is subject to mandatory inspections and reviews supervised by the European Union Aviation Safety Agency (EASA) in Europe and the FAA in the United States: an inspection every 400 to 600 flight hours; a thorough review every 20 to 24 months; a complete overhaul every four to five years requiring dismantling of the aircraft. In the meantime, many critical parts are replaced preventively according to thresholds defined by the manufacturers.
Small aircraft comply with lighter regulatory requirements. Their systems do not have the same level of redundancy. Maintenance is not as thorough. In these reports, the Bureau of Investigation and Analysis for Civil Aviation Safety (BEA) notes numerous accidents caused by parts that break because they were not replaced in time.
Pilot experience
The most determining factor, however, often remains the driver. According to the BEA, the main cause of fatal accidents in light aviation in France is loss of control in flight. A situation that training and experience can be avoided or corrected in the vast majority of cases.
In France, a private pilot license (PPL) is obtained with a minimum of 50 hours of flight time. An amateur pilot flies on average between 50 and 100 hours per year. An airliner captain flies between 400 and 800 hours per year and will accumulate experience of 10,000 and 20,000 hours during his career, according to the Civil Aviation Safety Directorate (DSAC) report. Above all, he follows numerous training courses each year. And he also works as a crew: if one pilot makes a mistake, the other can correct it.
Flight preparation and decision biases
According to the BEA, specific behaviors lead to small aircraft accidents, such as inadequate fuel management and maneuvers not necessary for flight control performed at low height. Likewise, surveys show a tendency for amateur pilots to fly despite unfavorable conditions. Pressure to arrive at your destination, the presence of passengers on board which creates a form of implicit obligation, group effect during club outings… all of this sometimes encourages taking too many risks.
These behaviors are almost absent in commercial aviation, where each decision is governed by codified procedures, verified by a second pilot and supervised by control bodies.
A final obstacle specific to light aviation complicates the analysis work: the absence of black boxes. Unlike airliners, small aircraft are not equipped with them. This is why the category “unknown or undetermined cause” appears in second position in the typology of fatal accidents in light aviation.
