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.

During landing and near the ground, with ASOS reported calm winds, the pilot stated that he seemed to be experiencing a tail wind. He noticed that we was about to touch down at a faster ground speed than he intended. He applied full power in an attempt to execute an go around. Instead of creating the take off lift that he needed, the power application resulted in an even faster ground speed that the aircraft touched down at.

Upon touch down, he stated that the aircraft duckwalked, bouncing between the left and right landing gear. This caused one of the left tire to pop, resulting in a roll to the left and subsequent abrupt stop and damage to the aircraft.

As the FAA filed it

HE NOTICED THAT WE WAS ABOUT TO TOUCH DOWN AT A FASTER GROUND SPEED THAN HE INTENDED. HE APPLIED FULL POWER IN AN ATTEMPT TO EXECUTE AN GO AROUND. INSTEAD OF CREATING THE TAKE OFF LIFT THAT HE NEEDED, THE POWER APPLICATION RESULTED IN AN EVEN FASTER GROUND SPEED THAT THE AIRCRAFT TOUCHED DOWN AT.

UPON TOUCH DOWN, HE STATED THAT THE AIRCRAFT DUCKWALKED, BOUNCING BETWEEN THE LEFT AND RIGHT LANDING GEAR. THIS CAUSED ONE OF THE LEFT TIRE TO POP, RESULTING IN A ROLL TO THE LEFT AND SUBSEQUENT ABRUPT STOP AND DAMAGE TO THE AIRCRAFT.
