## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of control - on ground/water, landing - roll
  - landing gear,normal brake system - failure,partial (cause)
  - maintenance,service of aircraft/equipment - improper, pilot in command (cause)
  - directional control - not maintained, pilot in command
  - ground loop/swerve - uncontrolled

## Analysis

THE PILOT AND THE OWNER OF THE AIRPLANE SERVICED THE BRAKES PRIOR TO TAKEOFF. WHEN THEY RETURNED FROM A LOCAL FLIGHT, THE RIGHT BRAKE WAS INOPERATIVE DURING THE LANDING ROLL-OUT. THE AIRPLANE GROUNDLOOPED TO THE LEFT, THEN WENT OFF THE LEFT EDGE OF THE RUNWAY, DAMAGING THE RIGHT WING AND HORIZONTAL STABILIZER.
