## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

POST-ACCIDENT INVESTIGATION REVEALED LESS THAN 1/3 OF A GALLON OF FUEL REMAINING IN THE AIRCRAFTS RIGHT FUEL TANK, 34 GALLONS REMAINING IN THE AIRCRAFTS LEFT TANK, AND THE AIRCRAFT GASCOLATOR CONTAINED NO FUEL.  INTERVIEW WITH PILOT REVEALED HE HAD NOT SWITCHED TANKS WHILE IN FLIGHT AND SUBSEQUENTLY RAN THE RIGHT TANK OUT OF FUEL.

## The NTSB's investigation of this event (1)

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.
