## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

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.
