## Sequence of events

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

- Loss of engine power(total) - nonmechanical, approach - vfr pattern - final approach
  - fluid,fuel - exhaustion (cause)
  - preflight planning/preparation - poor, pilot in command (contributing factor)
  - in-flight planning/decision - inadequate, pilot in command (cause)
- Forced landing, descent - emergency
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - ditch (contributing factor)

## Analysis

AT THE END OF A CROSS COUNTRY FLIGHT, WHILE ON FINAL APPROACH TO THE RUNWAY, THE RIGHT ENGINE QUIT. SHORTLY THEREAFTER, THE LEFT ENGINE QUIT. THE PILOT MADE A FORCED LANDING IN A FIELD SHORT OF THE RUNWAY WHERE DURING THE LANDING ROLL THE AIRPLANE COLLIDED WITH A DITCH. EXAMINATION OF THE AIRPLANE REVEALED THAT BOTH FUEL TANKS WERE NEARLY EMPTY OF FUEL.

## 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 19880608024109A](https://openairdocs.org/incident/19880608024109A), Jun 8, 1988: Gulstm 690C, Hayward, CA, Substantial damage. Both engines quit on final in sequence and were feathered. Crashed short of runway. Both fuel tanks were empty.

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.
