EnglishOn the 5th of May 2007 at 0005 local time, a Kenya Airway's Boeing B737-800 crashed a few minutes after take off from the Douala international airport (Cameroon), killing 114 persons. A statistical study shows that, worldwide, in recent years the rate of air crashes has decreased but the numbers of victims increased. Flight KQ507 crashed when meteorological conditions were bad, due to a particular convective system of type V. Bad weather was diagnosed using the instability indices computed from the soundings made at 1200 UTC and 0000 UTC 4 and 5 May 2007 respectively. The analysis of the fields of some meteorological parameters and the study of satellite images show that the meteorological situation was favourable to the development of this V type of system during the night of 4 to 5 May 2007 in the South of Cameroon. Evaluation of the contribution of the ETA weather model at 32 kilometres horizontal resolution and time intervals of 3 hours in forecasting this type of phenomenon has been done. It is found that its use in this region could help avoid such catastrophes. francaisLe 5 mai 2007 a 00 h 05, heure locale, un Boeing B737-800 de la compagnie Kenya Airways s'est ecrase peu apres son decollage de l'aeroport de Douala au Cameroun, faisant 114 morts. L'etude statistique montre que le taux d'accidents aeriens decroit alors que le nombre de victimes ne decroit pratiquement pas durant ces dernieres annees dans le monde. Cet accident du vol KQ507 avait lieu alors que les conditions meteorologiques etaient mauvaises, dues a un systeme convectif particulier de type V. Ce mauvais temps est diagnostique a l'aide des valeurs d'indices d'instabilites deduits des radiosondages de 12 h 00 UTC et 00 h 00 UTC les 4 et 5 mai 2007 respectivement. L'analyse des champs de certains parametres meteorologiques et l'etude de l'image satellitaire montrent que la situation meteorologique etait propice au developpement de ce type de systeme en V dans la nuit du 4 au 5 mai 2007 sur le sud du Cameroun. L'etude de l'apport du modele de prevision numerique ETA a 32 kilometres de resolution horizontale et 3 heures de resolution temporelle dans la prevision de ce type de phenomene a ete faite. Ce modele pourrait ameliorer sensiblement la prevention de telles catastrophes dans la region
