## Sequence of events

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

- Airframe/component/system failure/malfunction, taxi - to takeoff
  - fluid,hydraulic - leak (cause)
  - landing gear,normal brake system - inoperative (cause)
- Loss of control - on ground/water, taxi - to takeoff
  - directional control - not maintained, pilot in command (contributing factor)

  - terrain condition - rough/uneven (contributing factor)

## Analysis

AS THE PLT WAS TAXIING TO THE ACTIVE RWY, THE ACFT'S RIGHT BRAKE BECAME INOP DUE TO A LOSS OF HYDRAULIC FLUID. SUBSEQUENTLY, THE ACFT WENT OFF THE SIDE OF THE TAXIWAY, CONTD OVER AN EMBANKMENT & WAS DAMAGED. THE LOSS OF HYDRAULIC FLUID WAS DUE TO A LEAK IN THE WHEEL CYLINDER ON THE RIGHT MAIN GEAR.
