## 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
  - fluid,hydraulic - low level (contributing factor)
  - thrust reverser - other (contributing factor)
  - directional control - not maintained, pilot in command (cause)
- Main gear collapsed, landing - roll
  - terrain condition - ground (contributing factor)
  - landing gear,main gear - stress corrosion (contributing factor)

## Analysis

DURING FLIGHT, A DECREASE WAS NOTED IN THE QUANTITY OF UTILITY HYDRAULIC FLUID. THE ENGINE DRIVEN PUMPS WERE SHUT OFF UNTIL JUST BEFORE LANDING. AFTER EXTENDING THE GEAR & FLAPS, THE QUANTITY INDICATED 3.5 GAL & ALL PRESSURES WERE NORMAL. AFTER TOUCHDOWN, THE #1 REVERSER LIGHT WAS SLOW TO ILLUMINATE. REPORTEDLY, REVERSE THRUST WAS DELAYED ON THE #1 & #4 ENGINES UNTIL ALL REVERSER LIGHTS WERE ON. THE LANDING ROLL WAS REPORTED AS NORMAL UNTIL THE SPEED WAS SLOWED TO ABOUT 80 KTS, THEN THE PLANE BEGAN VEERING RIGHT. THE CAPTAIN STATED HE HAD NO LEFT BRAKING OR NOSE WHEEL STEERING. THE PLANE CONTINUED OFF THE RUNWAY & THE LEFT GEAR COLLAPSED. AFTER STOPPING, THE FIRE BOTTLES WERE USED WHEN SMOKE WAS OBSERVED FROM THE #1 ENGINE. LEFT & RIGHT TIRE MARKS WERE FOUND THAT WERE 1245 & 870 FT LONG, BOTH WITH SIGNS OF INTERMITTENT INTENSITY. THE NOSE WHEEL STEERING AND SPOILERS OPERATED WHEN THE UTILITY HYDRAULIC SYSTEM WAS FIRST POWERED BY THE AUX PUMP. A STRESS CORROSION CRACK WAS FOUND WHERE THE LEFT MAIN GEAR SIDEBRACE HAD FAILED.

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.
