What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Catastrophic failure of the throttle bellcrank/throttle cable bearing, throttle control became inoperative upon bearing failure. Pilot performed a successful running landing. Inspection of the throttle bellcrank revealed that the bearing linking the throttle control cable to the throttle bellcrank had disintegrated resulting in a total loss of rotorcraft throttle control. A mechanic commented that the throttle cable was mounted on the wrong side of the bellcrank assembly. There was also evidence of wear on the bellcrank adjacent to where the throttle cable was installed. Bearing may have failed due to improper routing of the throttle cable linkage.
