## Sequence of events

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

- Loss of engine power, takeoff - roll/run
  - fuel system - failure,total (cause)
- Overrun, takeoff
- On ground/water encounter with terrain/water, takeoff - roll/run
  - terrain condition - ditch (contributing factor)
  - terrain condition - high terrain (contributing factor)
- On ground/water collision with object, takeoff - roll/run
  - object - fence (contributing factor)

## Analysis

DURING THE TAKEOFF ROLL ON AN IFR FLT, THE RIGHT ENG LOST PWR AND THE PLT ABORTED THE TAKEOFF. THE ACFT RAN OFF THE END OF THE RWY, ACROSS TWO DITCHES, ONE ROAD, THROUGH A FENCE AND STRUCK A POST IN A FLD. DURING POST ACCIDENT TESTS, THE RIGHT ENG WOULD RUN ONLY WHEN IT WAS PRIMED WITH FUEL. THE EXACT PART OF THE FUEL SYSTEM THAT MALFUNCTIONED COULD NOT BE DETERMINED.
