A Robinson R66 helicopter, HB-ZOK, had just crossed the runway on arrival at Bern Airport, Switzerand.
At the same time, an Aero AT-3 was performing a touch-and-go manoeuvre on runway 14.
At an altitude of about 10 meters the aircraft suddenly banked 70 to the left. The instructor took over control and regained control of the aircraft.
The serious incident, which almost resulted in a crash of a light aircraft due to a loss of control, can be traced back to its entry into the wake turbulence of a helicopter. The insufficient awareness of the air traffic control and the crews of the danger of a helicopter's wake turbulence was identified as a causal factor.
