Factual narrative
A LOSS OF DIRECTIONAL CONTROL OCCURRED DURING LANDING ROLL. THE ACFT VEERED TO THE RIGHT, STRUCK A DITCH AND THEN NOSED OVER. A HELICOPTER WAS HOVERING TO THE LEFT OF THE LANDING RWY, PROBABLY CAUSING ENOUGH WAKE TURBULENCE TO CAUSE THE LOSS OF DIRECTIONAL CONTROL. LIGHT AND VARIABLE WINDS WERE ALSO PRESENT.
