## Probable cause

THE PILOT'S FAILURE TO MAINTAIN DIRECTIONAL CONTROL OF THE AIRPALNE. A FACTOR IN THE ACCIDENT WAS THE DITCH ALONG THE SIDE OF THE RUNWAY.

## Sequence of events

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

- On ground/water encounter with terrain/water, taxi - to takeoff
  - terrain condition - ditch (contributing factor)
  - directional control - not maintained, pilot in command (cause)
- Main gear collapsed, taxi - to takeoff
  - landing gear,main gear - overload

## Analysis

DURING THE TAXI FOR TAKEOFF, THE LEFT MAIN LANDING GEAR WHEEL ASSEMBLY ENTERED A DITCH ALONG THE SIDE OF THE RUNWAY AND COLLAPSED.
