The pilot in command and a passenger took off and were on their way to Ermelo to attend the "Ermelo 400 Enduro" motorcycle race which is to take place over the weekend. Shortly after take-off the main rotor went into an overspeed condition. The R44 possesses a low-inertia main rotor system and various levels of rotor system overspeeds can occur. The Robinson Maintenance Manual Model R44 (MMR44), Section 2.540, refers to Textron-Lycoming Service Bulletin 369 which states that for rotary wing aircraft using Textron-Lycoming engines, "no momentary overspeed is allowed".
By-standers observed the helicopter turn over the freeway between the Carnival City Casino and the Rondebult off-ramp in Boksburg and it then fell like a rock into a ditch in the grass on the side of the road. The pilot is reported to have broken both ankles and was admitted to the Glynwood Hospital. The passenger broke his leg badly and was airlifted to the Union Hospital in Alberton where he was to undergo an operation later.
