Analysis

As the helicopter was taking off, there was a loss of rotor RPM which was accompanied by a loss of fuel flow to the eng. The plt aborted the takeoff, but during touchdown, the main rotor blades flexed downward & severed the . Tail boom. An inspn of the eng revealed a 'b' nut on an air line between the governor & fuel control unit was cracked & loose, which permitted system leakage.
