What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) The helicopter lost power while in cruise flight at 1000' AGL and the student pilot privacy data omitted landed hard in the center of Chapin, SC high school football field collapsing the landing skids of the helicopter. Minor injuries to passenger's privacy data omitted wife ^privac^. After further investigation it was determined the a/c lost rotor speed due to the fact that privacy data omitted slipped her left arm out of her shoulder strap to be able to reach forward to make a GPS range adjustment. As she slipped her arm out of the left shoulder strap, the strap caught the idler pully/clutch t handle (located between the two seats at shoulder height) when she leaned forward this caused the rotor to become disengaged by pulling the t handle forward. Thus disengaging the clutch.
As the FAA filed it

MINOR INJURIES TO PASSENGER'S ^PRIVACY DATA^ WIFE ^PRIVAC^. AFTER FURTHER INVESTIGATION IT WAS DETERMINED THE A/C LOST ROTOR SPEED DUE TO THE FACT THAT ^PRIVACY DATA OMITTED^ SLIPPED HER LEFT ARM OUT OF HER SHOULDER STRAP TO BE ABLE TO REACH FORWARD TO MAKE A GPS RANGE ADJUSTMENT. AS SHE SLIPPED HER ARM OUT OF THE LEFT SHOULDER STRAP, THE STRAP CAUGHT THE IDLER PULLY/CLUTCH T HANDLE (LOCATED BETWEEN THE TWO SEATS AT SHOULDER HEIGHT) WHEN SHE LEANED FORWARD THIS CAUSED THE ROTOR TO BECOME DISENGAGED BY PULLING THE T HANDLE FORWARD. THUS DISENGAGING THE CLUTCH.
