Entre 2015 et 2019, en France, plus d’un accident mortel sur dix d’avion léger ou d’ULM multiaxe est consécutif à une diminution de la puissance du moteur au décollage. Cette étude présente les principales caractéristiques de ces accidents, telles que relevées lors des enquêtes conduites par le BEA. Elle décrit en particulier les origines probables ou avérées des pertes de puissance ainsi que les réactions les plus fréquemment observées dans ces circonstances, et les conséquences qui en découlent.

Towards the end of the 2000’s, the BEA observed that a number of public

air transport accidents or serious incidents were caused by a problem

relating to “aeroplane state awareness during go-around” (ASAGA). Other

events revealed inadequate management by the flight crew of the

relationship between pitch attitude and thrust, with go-around mode not

engaged, but with the aeroplane close to the ground and with the crew

attempting to climb.

Study concerning glider accidents over French territory between 1999 and 2001. A translation in German is also available.

The Robinson R 22 is a two-blade helicopter well-liked by flying clubs and individuals who find its performance good value for money. This has favoured the rise in the number of R 22s in France since its entry into service. The upsurge of R 22 accidents that occurred in 2000 highlighted the need to update the 1991 study. This new study concerns Robinson R 22 accidents that occurred between 1988 and 2001.

Study concerning the collisions that occurred over French territory between 1989 and 1999 and that involved at least one civil airplane.

1992-1999. Study concerning accidents that occurred during agricultural spraying flights on French territory between 1992 and 1999.

Many pilots use their aircraft in visual flight conditions for their personal and professional trips. The question must be asked, however, as to whether visual flying is best adapted for trips arranged on a long-standing basis for which the pressures and stakes are sometimes determining factors. This study analyses accidents where pilots were trying to reach their destination at all costs.
