The NTSB's narrative final · quoted from the NTSB record
THE PLT HAD JUST COMPLETED SPRAYING A FIELD & WAS IN A RIGHT TURN WHEN THE RIGHT WING TIP HIT GENTLY RISING TERRAIN. THE OWNER THOUGHT THAT THE PLT MIGHT HAVE DIVERTED HIS ATTENTION WHILE LOOKING AT A FARMER'S MAP TO LOCATE THE NEXT FIELD. (SEVERAL SIMILAR MAPS WERE FOUND IN THE SERVICE HANGER.) AN EXAM OF THE WRECKAGE & A TEARDOWN OF THE ENG REVEALED NO EVIDENCE OF A PREIMPACT/MECHANICAL MALFUNCTION OR FAILURE.

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 FTW83FA261.
