## Narrative

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

DURING A LOCAL FLIGHT, LANDING ON RWY 17, WITH SHIFTING WINDS, THE LEFT BRAKE SEEMED TO HAVE MORE EFFECT THAN THE RIGHT BRAKE.  THE AIRCRAFT DEPARTED THE RUNWAY TO THE LEFT AND FLIPPED OVER ON ITS BACK.  THE BRAKES WERE EXAMINED AND FOUND TO HAVE BEEN RECENTLY REPLACED.  THE LEFT BRAKE HAD MORE EFFECT THAN THE RIGHT BRAKE.

## The NTSB's investigation of this event (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
