Aviation safety reports, made easier to study
NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.
The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.
The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

THE FLIGHT WAS A PART 135 SIX-MONTH PROFICIENCY CHECK FOR THE PILOT IN THE LEFT SEAT. BOTH PILOTS WERE CHECK AIRMEN FOR THE COMMUTER AIR CARRIER. THE FLIGHT TOOK OFF AT 2343 AFTER CESSATION OF COMPANY REVENUE OPERATIONS. THE COCKPIT VOICE RECORDER RECORDED CONVERSATION OF BOTH PILOTS DISCUSSING AEROBATICS. THE PILOT IN THE LEFT SEAT STARTED TO DESCRIBE THE PERFORMANCE OF A PROHIBITED MANEUVER (APPARENTLY A BARREL ROLL). THE RECORDING ENDED BEFORE DESCRIPTION OF THE MANEUVER WAS COMPLETED. THE AIRPLANE IMPACTED IN A NOSE LEVEL ATTITUDE WITH THE LEFT WING SLIGHTLY DOWN. THERE WAS EVIDENCE THE MANEUVER WAS PERFORMED AT AN ALTITUDE INSUFFICIENT TO ASSURE RECOVERY OF THE AIRPLANE. A FILLED OUT GRADE SHEET FOR THE FLIGHT BEING FLOWN WAS FOUND IN THE CHECK AIRMAN'S MAILBOX. (FOR FURTHER INFORMATION, SEE NTSB SUMMARY REPORT NTSB/AAR-94/01/SUM)
NTSB Probable Cause
THE DELIBERATE DISREGARD FOR THE FEDERAL AVIATION REGULATIONS, GP EXPRESS PROCEDURES, AND PRUDENT CONCERN FOR SAFETY BY THE TWO PILOTS IN THEIR DECISION TO EXECUTE AN AEROBATIC MANEUVER DURING A SCHEDULED CHECK RIDE FLIGHT, AND THE FAILURE OF GP EXPRESS MANAGEMENT TO ESTABLISH AND MAINTAIN A COMMITMENT TO INSTILL PROFESSIONALISM IN THEIR PILOTS CONSISTENT WITH THE HIGHEST LEVELS OF SAFETY NECESSARY FOR AN AIRLINE OPERATING SCHEDULED PASSENGER SERVICE.
