Suosituksen perustelu
If light single-engine helicopters flying at the height and airspeed typical to helisawing operations encounter an engine failure or some other serious fault, they will face an emergency landing rather than a controlled autorotation. Several heli-sawing accidents have occurred in Finland.
Recommendation
Safety Investigation Authority, Finland recommends that the Finnish Transport Safety Agency exhaustively assess the practical procedures of operators that carry out heli-sawing flights. In addition, their regulations and the content and extent of training as well as their safety margins must also be established.
