  - fuel system,pump - failure,partial (cause)
  - fuel system,pump - pressure too low (cause)
  - fluid,fuel - starvation (cause)
- Overrun, takeoff
  - aborted takeoff - performed, pilot in command
- On ground/water encounter with terrain/water, takeoff
  - terrain condition - ditch (contributing factor)

  - landing gear,main gear - overload

## Analysis

THE PLT DETECTED A LOSS OF ENG TORQUE AT ABOUT ROTATION AIRSPEED ABOUT 1700 FT DOWN THE RWY & THE TAKEOFF WAS ABORTED. THE ACFT SLID INTO A DITCH OFF THE END OF THE RWY COLLAPSING THE MAIN GEAR. A FUNCTIONAL CHECK OF THE RIGHT ENG FUEL PUMP, P/N4V146R002, SER.#JX241439D, MANUFACTURED BY SPERRY VICKERS SHOWED THAT AT HIGH PUMP SPEED FUEL FLOW WAS INTERMITTENT. DISASSEMBLY OF THE PUMP REVEALED THAT THE ROTOR DRIVE SERRATIONS ON THE MAIN ROTOR DRIVE SHAFT, P/N330205,WERE WORN TO THE POINT THAT THE ROTOR WOULD SLIP ON THE SHAFT AT HIGH PUMP SPEEDS.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19820604020809A](https://openairdocs.org/incident/19820604020809A), Jun 4, 1982: Beech 6590, Wichita, KS, Substantial damage. Malfunction of fuel pump, p N4V146R002, caused pilot to abort takeoff, aircraft slid into 2 foot ditch.

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.
