## Probable cause

FAILURE OF RIGHT BRAKING ACTION DUE TO A HYDRAULIC LEAK.

## 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)
  - fluid,hydraulic - leak (cause)
  - directional control - not possible
  - ground loop/swerve - uncontrolled
- On ground/water collision with object, landing - roll
  - object - aircraft parked/standing

## Analysis

DURING THE ROLL-OUT AFTER LANDING, THE RIGHT BRAKE MALFUNCTIONED. THE PILOT TURNED OFF ONTO A TAXIWAY AT THE END OF THE RUNWAY & THE PLANE COLLIDED WITH TWO PARKED AIRPLANES. EXAMINATION OF THE BRAKES REVEALED A HYDRAULIC LEAK AT THE RIGHT WHEEL.

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.
