## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(-23) WHILE CONDUCTING STUDENT FLIGHT TRAINING @ 1700 FT, 7 MILES NE OF CNO, THE HELICOPTER EXPERIENCED VIBRATIONS, THEN THE GEARBOX CHIP DETECTOR LIGHT ILLUMINATED. PER ESTABLISHED PROCEDURES, THE INSTRUCTOR PILOT MADE A PRECAUTIONARY LANDING IN A FIELD. HE CALLED THE CNO MANAGER OF SILVER STATE HELICOPTERS, WHO TOLD HIM THAT THE DECISION TO FLY BACK TO CNO WAS UP TO HIM. THE PILOT AGREED, BUT ASKED THAT ANOTHER HELICOPTER BE DISPATCHED TO PICK UP HIS STUDENT. WHEN THE PILOT TOOK OFF, THE CHIP DETECTOR LIGHT CAME ON AGAIN. AFTER A 7 MILE FLIGHT, HE ARRIVED AT CNO SAFELY. THE PILOT FLEW THE AIRCRAFT WITHOUT COORDINATION WITH THE CHIEF INSTRUCTOR PILOT OR MAINTENANCE. MAINTENANCE DISCOVERED METAL SHAVINGS ON THE CHIP DETECTOR MAGNET. AS A RESULT OF THE SHAVINGS, THE TAIL ROTOR GEARBOX REQUIRES REPLACING. THE STATION MANAGER, CHIEF INSTRUCTOR PILOT, AND MECHANIC WAS COUNSELED ON THE IMPORTANCE OF FOLLOWING ESTABLISHED COMPANY MAINTENANCE PROCEDURES.
