Whereas wake turbulence is commonly a topic within commercial aviation which is involving large/ heavy transport aircraft, there can also be a hazard for general aviation flight operations. This has been investigated for a specific case of an accident where an aircraft of class E (one engine with a maximum takeoff weight up to 2 tons) took off behind an aircraft with 5.5 tons maximum takeoff weight. Based on available information and several assumptions the potential wake turbulence situation for the specific aircraft combination has been assessed. The roll axis was the dominating factor in this case. Accordingly, the wake induced rolling moment was analysed and related to the assumed available roll control power. Furthermore, the wake vortex behaviour was simulated. The results indicate that wake turbulence can likely be considered to be the main reason for the accident.
