Brice ROTORWAY EXEC 162F
The pilot reported, 'After normal preflight, I lifted off into a hover an air taxied approx 120' towards runway. I sat the helicopter down to turn on my avionics switch. I must not have lowered collective fully, as when I removed my hand from the cyclic, & the wind shifted (which is common at this airport) slightly to right front quarter, it displaced the rotor blades causing a dynamic rollover to the left.' The pilot stated, 'I was concentrating on my slope landing and thinking of my subsequent slope departure so thoroughly I that I did not positively notice rotor rpm dropping as I should have before taking my hand off the cyclic.' The pilot reported that the accident could have been prevented by, 'Lowering collective fully before removing hand from cyclic'.
