What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The solo pilot is a student pilot with training in the R22 and R44 rotorcraft. This rotorcraft is a single seat, the pilot elected to solo himself un-supervised. He stated the following:
Normal start up and rotor run up procedures were followed. The collective was raised for a two stage pickup. When the helicopter was light on the skids, some right yaw was detected and corrected. When raising the collective further to initiate ascent, the helicopter left the ground and darted forward and left. Pilot attempted to correct that movement and apparently over controlled the rotorcraft. The rotorcraft started swinging back and forth (the pendulum effect). Pilot never had control of the rotorcraft after its skids left the ground. The helicopter was airborne for less than 10 seconds. It never reached an altitude greater than 5 feet AGL. It hit the ground left (port) skid low and the main rotor blade hit the ground on the left (port) side of the helicopter.
As the FAA filed it
THE SOLO PILOT IS A STUDENT PILOT WITH TRAINING IN THE R22 AND R44 ROTORCRAFT. THIS ROTORCRAFT IS A SINGLE SEAT, THE PILOT ELECTED TO SOLO HIMSELF UN-SUPERVISED. HE STATED THE FOLLOWING:
NORMAL START UP AND ROTOR RUN UP PROCEDURES WERE FOLLOWED. THE COLLECTIVE WAS RAISED FOR A TWO STAGE PICKUP. WHEN THE HELICOPTER WAS LIGHT ON THE SKIDS, SOME RIGHT YAW WAS DETECTED AND CORRECTED. WHEN RAISING THE COLLECTIVE FURTHER TO INITIATE ASCENT, THE HELICOPTER LEFT THE GROUND AND DARTED FORWARD AND LEFT. PILOT ATTEMPTED TO CORRECT THAT MOVEMENT AND APPARENTLY OVER CONTROLLED THE ROTORCRAFT. THE ROTORCRAFT STARTED SWINGING BACK AND FORTH (THE PENDULUM EFFECT). PILOT NEVER HAD CONTROL OF THE ROTORCRAFT AFTER ITS SKIDS LEFT THE GROUND. THE HELICOPTER WAS AIRBORNE FOR LESS THAN 10 SECONDS. IT NEVER REACHED AN ALTITUDE GREATER THAN 5 FEET AGL. IT HIT THE GROUND LEFT (PORT) SKID LOW AND THE MAIN ROTOR BLADE HIT THE GROUND ON THE LEFT (PORT) SIDE OF THE HELICOPTER.
