## Probable cause

THE PILOT'S IMPROPER FUEL TANK SELECTION AND THE SUBSEQUENT LOSS OF ENGINE POWER DUE TO FUEL STARVATION. A FACTOR WAS THE LACK OF SUITABLE TERRAIN.

## 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 - base turn
  - fuel tank selector position - improper, pilot in command (cause)
  - fluid,fuel - starvation (cause)
- Forced landing, descent - emergency
- In flight collision with terrain/water, landing - flare/touchdown
  - terrain condition - none suitable (contributing factor)
  - terrain condition - soft
- Nose over, landing - roll
  - landing gear,nose gear - collapsed

## Analysis

FOLLOWING A DESCENDING TURN FROM DOWNWIND TO BASE THE PILOT ADDED POWER, HOWEVER, THE ENGINE DID NOT RESPOND. HE SWITCHED TANKS FROM THE LEFT TO THE RIGHT AND TURNED THE FUEL BOOST PUMP ON, THIS HAD NO EFFECT ON ENGINE POWER AND THE PILOT THEN RESELECTED THE LEFT TANK. THE PILOT EXECUTED A FORCED LANDING TO AN OPEN FIELD. DURING THE FORCED LANDING THE AIRPLANE LANDED HARD AND DURING THE LANDING ROLL THE AIRPLANE NOSE GEAR COLLAPSED IN THE SOFT EARTH, CAUSING THE AIRPLANE TO NOSE OVER TO THE INVERTED POSITION.

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.
