Aircraft involved
Probable cause & findings
THE PILOT-IN-COMMAND'S FAILURE TO MAINTAIN DIRECTIONAL CONTROL AFTER A PARTIAL FAILURE OF THE NORMAL BRAKE SYSTEM.
Factual narrative
THE PILOT SAID THAT DURING LANDING ROLL ON A FUEL STOP, THE AIRPLANE SWERVED TO THE LEFT. HE ATTEMPTED TO CORRECT WITH RIGHT BRAKE, TO NO AVAIL. THE PLANE GROUND LOOPED OFF THE LEFT SIDE OF THE RWY AND ENTERED SOFT TERRAIN. THE PLANE NOSED OVER AND CAME TO REST INVERTED. A POST-ACCIDENT INVESTIGATION BY AN FAA INSPECTOR REVEALED THAT THE RIGHT BRAKE PADS WERE WORN AND REQUIRED MORE FLUID FROM THE BRAKE RESERVOIR. THE FLUID LEVEL IN THE RESERVOIR WAS LOW. NO LEAKS OR OTHER PROBLEMS WERE FOUND ON THE BRAKE SYSTEM. THIS AIRCRAFT WAS AN EXPERIMENTAL DESIGN WITH LANDING GEAR ON THE TOP SIDE OF THE WINGS, MAKING IT CAPABLE OF INVERTED LANDINGS. THE SAME FLUID RESERVOIR SERVED BOTH SETS OF BRAKES. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
