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 ACFT IMPACTED THE GROUND IN AN INVERTED POSITION IN ABOUT A 30 DEGREE NOSE DOWN ATTITUDE. THE ACFT WAS OBSERVED DOING AEROBATICS WITH THE LAST MANEUVER A SPIN. THE ACFT SPUN TO AN OUT OF SIGHT POSITION BEHIND THE TREES AND A CRASH WAS HEARD. THE CFI ON THIS FLT HAD BEEN KNOWN TO PERFORM AEROBATICS IN THIS ACFT AND TO ALLOW STUDENTS TO DO THEM. THE PILOT RECEIVING INSTRUCTION ON THE DAY OF THE FLT HAD BEEN RECOMMENDED FOR AN INSTRUMENT RATING CHECK RIDE. ONE PILOT WHO HAD FLOWN WITH THIS CFI SAID LIMITED AEROBATICS HAD BEEN PERFORMED WITH HIM BUT THE CFI PERFORMED AT A POOR PROFICIENCY LEVEL DURING AEROBATICS. A NOTED AEROBATIC PILOT WHO HAD FLOWN THIS ACFT SAID IT SPUN RELATIVELY FLAT. HE STATED THAT WITHOUT TRAINING MOST PROFESSIONAL AEROBATIC PILOTS WERE UNABLE TO RECOGNIZE EITHER THE DIRECTION OR PROPER PROCEDURE FOR RECOVERY FROM AN INVERTED FLAT SPIN.
