Narrative:While cruising at an altitude of 1,350 feet MSL, the pilot felt a 'sudden hesitation and [smelled the] odor of smoke.' While 'determining if [a] serious malfunction existed,' the helicopter experienced a loss of main rotor drive and altitude, 'along with a stronger burning odor.' The pilot initiated an autorotation to a field adjacent to a school. However, prior to reaching the intended landing area, the helicopter struck a pickup truck, 'flipped over, landed in [the] field and started on fire.' The pilot reported that prior to the flight he had adjusted the alignment of the main drive belt and engine.
Probable Cause: The improper alignment of the main drive belt by the owner/pilot/mechanic, which resulted in the failure of the main drive belt. A factor was the lack of suitable terrain for the forced landing.
