The NTSB's narrative final · quoted from the NTSB record
THE FOREIGN REGISTERED PLT HAD A STATEMENT OF AEROBATIC COMPETENCY BY AN FAA INSPECTOR WHICH CONTAINED A MIN ALT LIMITATION OF 300 FT AGL. WHILE PERFORMING AT AN AIR SHOW, HE HAD PLANNED TO PULL UP IN A HALF LOOP, MAKE A HALF ROLL ON TOP, ENTER A 2 TURN SPIN & RECOVER. THE MANEUVER WAS GENERALLY FLOWN AS BRIEFED; HOWEVER, THE ACFT STRUCK THE GROUND BEFORE COMPLETELY RECOVERING FROM THE SPIN. SEVERAL QUALIFIED AEROBATIC PLTS AGREED THE HALF LOOP WAS INITIATED FROM ABOUT 100 FT AGL & THAT THE SPIN ROTATION HAD STOPPED AT ABOUT 300 FT AGL, BUT THE ACFT WAS IN APRX AT 10 DEG NOSE DOWN ATTITUDE WHEN IT HIT THE GROUND. THE PLT RECEIVED SEVERE NECK, BACK & BRAIN INJURIES & DIED 6 DAYS LATER. NO EVIDENCE OF A MALFUNCTION OR FAILURE OF THE ACFT WAS FOUND.

About this page
Everything above comes from the NTSB's public accident database: the narrative, probable cause and findings are the NTSB's own words, and the coded tables behind its report (pilot, aircraft, flight, weather, injuries, sequence of events) are written out in plain English. Pilots' ages, home towns and medical details are left out on purpose. The docket at the NTSB holds the report as a PDF and the investigation's photographs and documents. This site never names pilots, passengers or anyone else involved. A preliminary report describes what is known soon after the event and can change; the final report, with the probable cause, usually follows one to two years later and this page is refreshed when it does. Case number CHI83FA371.
