## Probable cause

FUEL STARVATION FOR UNDETERMINED REASONS.  FACTORS RELATED TO THE ACCIDENT WERE IN BLOWN FUSE WHICH RENDERED THE BOOST PUMP INOPERATIVE AND THE ROUGH TERRAIN IN WHICH THE EMERGENCY LANDING WAS MADE.

## 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 - starvation (cause)
  - reason for occurrence undetermined (cause)
- Forced landing, descent - emergency
  - remedial action - attempted, pilot in command
  - electrical system,fuse - open (contributing factor)
  - fuel system,electric boost pump - inoperative (contributing factor)
- Nose gear collapsed, landing - roll
  - terrain condition - rough/uneven (contributing factor)

## Analysis

A LOSS OF ENGINE POWER WAS EXPERIENCED WHILE ON FINAL APPROACH DURING THE LAST LEG OF A CROSS COUNTRY FLIGHT.  THE PILOT TURNED ON THE FUEL SYSTEM ELECTRIC BOOST PUMP AND POWER WAS MOMENTARILY REGAINED.  THE PILOT SELECTED AN OPEN FIELD IN WHICH TO MAKE AN EMERGENCY LANDING AND DURING THE LANDING ROLL ON THE ROUGH TERRAIN, THE NOSE GEAR COLLAPSED. POST ACCIDENT INSPECTION REVEALED THE RIGHT FUEL TANK WAS EMPTY AND THE LEFT TANK WAS 1/2 FULL.  THE PILOT REPORTED FLYING ON THE LEFT TANK WHEN THE POWER LOSS OCCURRED.  THE ONLY DISCREPANCY NOTED DURING THE INSPECTION WAS THE 50 AMP FUSE ON WHICH THE ELECTRIC BOOST PUMP OPERATES WAS BLOWN.

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.
