The studies carried out by the BEA are an extension of the investigations. They cover a large spectrum and make an effective tool, particularly for:
- analyzing a type of given occurrence (« fuel starvation » or « mid-air collisions » for example) ;
- analyzing an identified recurring factor in recent events (« get-home-itis » or « GPS events » for example) ;
- drawing up an inventory and report on a specific point (the performance of FDR's or the follow up of recommendations for example) ;
- conducting a critical analysis of the investigation methods used.
This work draws on data recorded at the end of the investigations (by the BEA or its foreign counterparts), on the skills of the BEA’s experts, on joint efforts with research bodies or industrial groups (manufacturers, airlines), etc.
The results of these studies may, should the need arise, lead the BEA to issue safety recommendations.
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.
A study carried out by the BEA in 1995 showed that between 1991 and 1995, 79 accidents were due to running out of petrol and resulted in five deaths and 24 injured. Between 1996 and 2000, 51 similar accidents had caused four deaths and 22 injured and 41 incidents were listed: making a total of nine deaths and 46 injured between 1991 and 2000.
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.
