## Probable cause

THE PILOT BECAME DISORIENTED AND DELAYED IN TAKING REMEDIAL ACTION, WHICH RESULTED ON A CRITICALLY LOW FUEL LEVEL. A FACTOR RELATED TO THE ACCIDENT WAS:  ROUGH/UNEVEN TERRAIN IN THE EMERGENCY LANDING AREA.

## Sequence of events

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

- Main gear collapsed, landing - roll
  - became lost/disoriented - inadvertent, pilot in command (cause)
  - remedial action - delayed, pilot in command (cause)
  - fluid,fuel - low level (cause)
  - precautionary landing - performed, pilot in command
  - terrain condition - rough/uneven (contributing factor)
  - landing gear,main gear - overload

## Analysis

THE PILOT AND FOUR PAX (HIS FAMILY) WERE ON A X-COUNTRY FLIGHT. THE PILOT SAID HE BECAME DISORIENTED WHILE NAVIGATING BY LORAN AND FLEW UNTIL THE PLANE WAS LOW ON FUEL. SUBSEQUENTLY, HE MADE AN EMERGENCY LANDING BESIDE A HIGHWAY. DURING THE LANDING ROLL, THE RIGHT MAIN GEAR COLLAPSED AND THE ACFT WAS DAMAGED. A POST ACCIDENT INVESTIGATION REVEALED THERE WAS NO FUEL IN EITHER TANK.
