THE PILOT, WHILE CONDUCTING AERIAL APPLICATIONS,  HEARD A "LOUD POP" AND NOTED THAT THE MAIN ROTOR RPM WAS BEGINNING TO DECAY.  HE THEN ATTEMPTED TO AUTOROTATE THE AIRCRAFT TO A LANDING. THE SUBSEQUENT LANDING RESULTED IN SUBSTANTIAL DAMAGE TO THE AIRCRAFT. THE PILOT WAS NOT INJURED.

## The NTSB's investigation of this event (1)
