Narrative

THE PILOT STATED HE WAS ON A LOCAL FLIGHT IN DUSK/BRIGHT NIGHT 
   CONDITIONS. HE REPORTED HE HAD THE LANDING LIGHT, POSITION AND 
   ANTI-COLLISION LIGHTS ON, AND "COULD SEE PRETTY GOOD IN A CONFINED AREA 
   THAT I HAD BEEN IN MANY TIMES." AFTER SOME MANEUVERING, THE PILOT 
   DECIDED TO LAND.  HE STATE D: "I DIDN'T THINK I HAD ANY LATERAL 
   MOVEMENT.  I PERCEIVED MY (ALTITUDE) TO BE APPROXIMATELY 3 FEET, I MUST 
   HAVE BEEN HIGHER.  I REMEMBER MY LEFT SKID HITTING THE GROUND THEN 
   SORT OF A TILT TO THE RIGHT.  MY RIGHT SKID CAUGHT IN SOME DIRT TO THE 
   RIGHT AND THE NEXT THING I KNOW THE HELICOPTER TIPPED OVER."
