## Analysis

THE PILOT EXPERIENCED ENGINE POWER FAILURE DUE TO FUEL EXHAUSTION FOR UNKNOWN REASONS SINCE ABOUT 30 GALLONS OF FUEL SHOULD HAVE BEEN ON BOARD WHEN THE CRASH OCCURRED. THE PILOT WAS VECTORED TOWARD THE NEAREST AIRPORT BUT WAS UNABLE TO REACH IT AND CRASHED INTO A ROUGH AND ROCKY TREE-COVERED HILLSIDE ABOUT ONE-HALF MILE SHORT OF THE APPROACH END OF THE INTENDED RUNWAY. AN OPERATIONAL CHECK OF THE ENGINE AT A LATER DATE REVEALED NO EVIDENCE OF ABNORMALITIES.

## 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 19850614025699A](https://openairdocs.org/incident/19850614025699A), Jun 14, 1985: Cessna T210N, Mineral Wells, TX, Destroyed. Fuel exhaustion. Hit trees on emergency landing. No explanation for the loss of 30 gallons of fuel.

## Other investigations on N6993N (2)

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.
