ON FINAL APPROACH INTO GREAT FALLS, MONTANA THE PILOT NOTED A FULL DEPLOYMENT OF THE SAME SPOILER PANEL. NO WARNING LIGHTS WERE OBSERVED BY THE CREW, ALTHOUGH IT WAS NOTED ON THE PFCS INDICATOR.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
