Probable cause
the maintenance personnel's failure to install the cotter pins that secured castellated nuts on the left elevator vertical hinge bolts, which resulted in the left elevator partially detaching in flight. Contributing to the accident was the failure of maintenance personnel to document the non-routine maintenance procedure that was used to remove and reinstall the elevator during maintenance.
