## 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
  - hydraulic system,pressure regulator - jammed (cause)
  - safety system(other) - inoperative (cause)
  - hydraulic system,pump - overtemperature (cause)
  - hydraulic system,pump - failure,total (cause)
  - fluid,hydraulic - no pressure (cause)
- Loss of control - on ground/water, taxi - to takeoff
  - landing gear,steering system - disabled (cause)
  - directional control - not possible, pilot in command
  - landing gear,normal brake system - disabled (cause)
  - brakes(normal) - not possible, pilot in command
  - landing gear,emergency brake system - disabled (cause)
  - brakes(emergency) - not possible, pilot in command
- On ground/water encounter with terrain/water, taxi - to takeoff
  - terrain condition - downhill (contributing factor)
  - terrain condition - ditch (contributing factor)

## Analysis

DURING TAXI FOR TAKEOFF, NOSEWHEEL STEERING WAS LOST AND THE AIRCRAFT DEPARTED THE TAXIWAY AND WENT DOWN AN EMBANKMENT AND INTO A DRAINAGE DITCH CAUSING MINOR DAMAGE. DURING THE HYDRAULIC SYSTEM CHECK-OUT, THE HYDRAULIC PUMP MOTOR WAS FOUND BURNT OUT. THE HYDRAULIC PRESSURE CONTROL SWITCH WOULD NOT OPEN WHEN THE SYSTEM PRESSURE REACHED PRESCRIBED LIMITS. ADDITIONALLY, THE HYDRAULIC PUMP TIMING RELAY WAS FOUND TO BE INOPERATIVE REGARDLESS OF THE LENGTH OF TIME THAT D.C. POWER WAS APPLIED.

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.
