What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) This aircraft was engaged in logging operations, by erickson air crane, inc., E8KL, near Applegate lake in southwest Oregon. The PIC made a precautionary landing when he sensed something was not quite right with the aircraft. A post flight inspection by the assistant crew chief discovered that the lower attachment pin for a primary control servo was missing. Further investigation found that a nut had backed off the servo retaining plate which allowed the pin to exit the attachment point.
