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.

The first attempt to land the aircraft was aborted and a go-around performed because the pilot stated he was going too fast. He believed that he was selecting 30 degrees of flaps, but only physically achieving 10 degrees and that was causing the fast approach. On the second attempt, the aircraft landed on runway 26 carrying more speed and touching down farther down the runway than the pilot desired. Runway 26 is asphalt, 2610' x 60', and descends 40' in altitude over its length. The pilot stated he tried to select 30 degrees, full flaps, to slow him down while rolling out down the runway but believed only 10 degrees was achieved. Pilot stated he usually does not use brakes because the flaps act as brakes. As the aircraft approached the end of the runway he was still going too fast and the brakes were applied gradually and then more vigorously. The aircraft veered both left and right, then left again and off the runway about 120 feet from the on-coming end of the asphalt. The right wing-tip dipped to contact the runway as the aircraft angled off the runway. The nose gear and rotating propeller contacted a two foot tall berm of plowed snow within a couple feet of the runway edge. The aircraft immediately tipped over forward and came to rest on its back, facing the direction it had come from. The pilot stated there could have been black ice in patches on the runway that affected braking. A local mechanic and the airport manager that heard the accident and were on scene in minutes stated the runway was dry. There was some snow on the runway where the propeller had kicked it when contacting the berm. Inspection of the aircraft after it was righted showed the flap selector was in the 20 degree detent and the flaps were positioned at 20 degrees. Local weather from an agrimet station on field indicated 40 degrees f with winds light (2-3 mph) and from variable directions.

As the FAA filed it

THE FIRST ATTEMPT TO LAND THE AIRCRAFT WAS ABORTED AND A GO-AROUND PERFORMED BECAUSE THE PILOT STATED HE WAS GOING TOO FAST. HE BELIEVED THAT HE WAS SELECTING 30 DEGREES OF FLAPS, BUT ONLY PHYSICALLY ACHIEVING 10 DEGREES AND THAT WAS CAUSING THE FAST APPROACH. ON THE SECOND ATTEMPT, THE AIRCRAFT LANDED ON RUNWAY 26 CARRYING MORE SPEED AND TOUCHING DOWN FARTHER DOWN THE RUNWAY THAN THE PILOT DESIRED. RUNWAY 26 IS ASPHALT, 2610' X 60', AND DESCENDS 40' IN ALTITUDE OVER ITS LENGTH. THE PILOT STATED HE TRIED TO SELECT 30 DEGREES, FULL FLAPS, TO SLOW HIM DOWN WHILE ROLLING OUT DOWN THE RUNWAY BUT BELIEVED ONLY 10 DEGREES WAS ACHIEVED. PILOT STATED HE USUALLY DOES NOT USE BRAKES BECAUSE THE FLAPS ACT AS BRAKES. AS THE AIRCRAFT APPROACHED THE END OF THE RUNWAY HE WAS STILL GOING TOO FAST AND THE BRAKES WERE APPLIED GRADUALLY AND THEN MORE VIGOROUSLY. THE AIRCRAFT VEERED BOTH LEFT AND RIGHT, THEN LEFT AGAIN AND OFF THE RUNWAY ABOUT 120 FEET FROM THE ON-COMING END OF THE ASPHALT. THE RIGHT WING-TIP DIPPED TO CONTACT THE RUNWAY AS THE AIRCRAFT ANGLED OFF THE RUNWAY. THE NOSE GEAR AND ROTATING PROPELLER CONTACTED A TWO FOOT TALL BERM OF PLOWED SNOW WITHIN A COUPLE FEET OF THE RUNWAY EDGE. THE AIRCRAFT IMMEDIATELY TIPPED OVER FORWARD AND CAME TO REST ON ITS BACK, FACING THE DIRECTION IT HAD COME FROM. THE PILOT STATED THERE COULD HAVE BEEN BLACK ICE IN PATCHES ON THE RUNWAY THAT AFFECTED BRAKING. A LOCAL MECHANIC AND THE AIRPORT MANAGER THAT HEARD THE ACCIDENT AND WERE ON SCENE IN MINUTES STATED THE RUNWAY WAS DRY. THERE WAS SOME SNOW ON THE RUNWAY WHERE THE PROPELLER HAD KICKED IT WHEN CONTACTING THE BERM. INSPECTION OF THE AIRCRAFT AFTER IT WAS RIGHTED SHOWED THE FLAP SELECTOR WAS IN THE 20 DEGREE DETENT AND THE FLAPS WERE POSITIONED AT 20 DEGREES. LOCAL WEATHER FROM AN AGRIMET STATION ON FIELD INDICATED 40 DEGREES F WITH WINDS LIGHT (2-3 MPH) AND FROM VARIABLE DIRECTIONS.
