From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry 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.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

(-23) The pilot attempted another takeoff after aborting his first attempt on runway 22 which is 3600' long with 8 degree upslope. The surface wind was less than 10 knots and slightly from the left. The pilot stated that he had approximately 14 gallons of fuel on board and that he and his passenger weighed 450 lbs. He said that his OAT gauge read 33 degrees c (96 degrees f). This puts the airplane about 100 lbs. Over maximum allowable gross weight and the density altitude at approximately 3000 feet. Takeoff performance was severely and adversely compromised. Witnesses said the engine noise sounded normal but the airplane didn't become airborne until the last third of the runway. They ran out to watch as it cleared a fence at the airport boundary by only five or ten feet. The nose was higher than normal as the airplane "mushed" over a fence at the airport boundary. The left wing dropped and it impacted in a soybean field left wing first and flipped upside down. The occupants exited the airplane.

As the FAA filed it

(-23) THE PILOT ATTEMPTED ANOTHER TAKEOFF AFTER ABORTING HIS FIRST ATTEMPT ON RUNWAY 22 WHICH IS 3600' LONG WITH 8 DEGREE UPSLOPE. THE SURFACE WIND WAS LESS THAN 10 KNOTS AND SLIGHTLY FROM THE LEFT. THE PILOT STATED THAT HE HAD APPROXIMATELY 14 GALLONS OF FUEL ON BOARD AND THAT HE AND HIS PASSENGER WEIGHED 450 LBS. HE SAID THAT HIS OAT GAUGE READ 33 DEGREES C (96 DEGREES F). THIS PUTS THE AIRPLANE ABOUT 100 LBS. OVER MAXIMUM ALLOWABLE GROSS WEIGHT AND THE DENSITY ALTITUDE AT APPROXIMATELY 3000 FEET. TAKEOFF PERFORMANCE WAS SEVERELY AND ADVERSELY COMPROMISED. WITNESSES SAID THE ENGINE NOISE SOUNDED NORMAL BUT THE AIRPLANE DIDN'T BECOME AIRBORNE UNTIL THE LAST THIRD OF THE RUNWAY. THEY RAN OUT TO WATCH AS IT CLEARED A FENCE AT THE AIRPORT BOUNDARY BY ONLY FIVE OR TEN FEET. THE NOSE WAS HIGHER THAN NORMAL AS THE AIRPLANE "MUSHED" OVER A FENCE AT THE AIRPORT BOUNDARY. THE LEFT WING DROPPED AND IT IMPACTED IN A SOYBEAN FIELD LEFT WING FIRST AND FLIPPED UPSIDE DOWN. THE OCCUPANTS EXITED THE AIRPLANE.
