## Probable cause

INADEQUATE PREFLIGHT PLANNING, WHICH RESULTED IN AN INADEQUATE FUEL SUPPLY AND FUEL EXHAUSTION.

## Sequence of events

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

- Loss of engine power(total) - nonmechanical, approach
  - aircraft preflight - inadequate, pilot in command (cause)
  - fluid,fuel - exhaustion (cause)
  - fuel supply - inadequate, pilot in command (cause)
- Forced landing, descent - emergency
- In flight collision with object, landing
  - object - tree(s)

## Analysis

THE STUDENT PILOT REFUELED AT HIS FIRST STOP ON A CROSS-COUNTRY FLIGHT, RATHER THAN AT THE SECOND STOP AS RECOMMENDED BY HIS FLIGHT INSTRUCTOR.  AS HE WAS APPROACHING TO LAND AT HIS FINAL DESTINATION, THE ENGINE LOST POWER.  THE AIRCRAFT CRASHED IN TREES ABOUT ONE HALF MILE FROM THE ACTIVE RUNWAY.  AN INVESTIGATION REVEALED THAT LESS THAN ONE GALLON OF FUEL WAS REMAINING IN EACH OF THE TWO WING TANKS.  UNUSABLE FUEL FOR THIS AIRCRAFT WAS 3.5 GALLONS.

## 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 19910916044509A](https://openairdocs.org/incident/19910916044509A), Sep 16, 1991: Cessna 150M, Portland, OR, Substantial damage. Student on crosscountry saw he was low on fuel but believed he could make it. Ran out of fuel on final approach.

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.
