Read the full NTSB narrative

THE HELICOPTER COLLIDED WITH TREES AND ROLLED OVER DURING A FORCED LANDING AFTER ENGINE FAILURE. THE PLT HAD BEEN TAKINGPASSENGERS UP FOR SIGHT-SEEING FOR SEVERAL HOURS. AFTER THE LAST FLT HE AND HIS WIFE HAD DEPARTED THE CITY PARK TO FLY BACK TO THE ACFT HOME BASE. ABOUT 2 MILES LATER THE ENGINE FAILED. DUE TO STRONG WINDS THE PLT COULD NOT REACH A VACANT SCHOOL YARD AND CRASHED INTO TREES. THE ACFT ENGINE HAD A HISTORY OF OIL USE; ABOUT ONE QUART OF OIL PER HOUR. THE PLT STATED HE HAD FLOWN OVER AN HOUR SINCE CHECKING THE OIL. AFTER THE ACCIDENT THE ENGINE OIL TANK WAS CHECKED AND FOUND EMPTY. THE TANK WAS NOT DAMAGED AND THERE WAS NO SIGN OF LEAKAGE. THE MANNER OF THE ENGINE FAILURE WAS REPRESENTATIVE OF AN OIL DEPLETION FAILURE WITH SOME AREAS OF DAMAGE SHOWING SIGNS OF EXTREME OVERHEATING.
