THE CFI AND THE RATED STUDENT PILOT WERE IN LEVEL FLIGHT WHEN ONE ROTOR BLADE STRUCK THE CABIN AREA. THE HELICOPTER DESCENDED OUT OF CONTROL AND CRASHED.

EXAMINATION OF THE FLIGHT CONTROLS REVEALED OVERLOAD FRACTURES OF THE CYCLIC AND COLLECTIVE CONTROL TUBES. THE CFI HAD COMPLETED AN INSTRUCTIONAL FLIGHT WITH ANOTHER STUDENT 1/2 HOUR PRIOR TO THE ACCIDENT.
