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

- Loss of engine power(partial) - nonmechanical, takeoff - initial climb
  - engine instruments,fuel quantity gage - false indication (contributing factor)
  - aircraft preflight - inadequate, pilot in command (cause)
  - fluid,fuel - starvation (cause)
  - fuel supply - misjudged, pilot in command (cause)
  - precautionary landing - initiated, pilot in command
- Loss of engine power(total) - nonmechanical, approach - vfr pattern - base leg/base to final
  - fluid,fuel - exhaustion (cause)
  - aircraft performance,two or more engines - inoperative (cause)
- Forced landing, landing - flare/touchdown
- In flight collision with terrain/water, landing - flare/touchdown

## Analysis

DURING TAKEOFF, THE REAR ENGINE LOST POWER AT ABOUT 600 FT AGL, AND ABOUT 20 SECONDS LATER, THE FRONT ENGINE LOST POWER. THE PILOT HAD TURNED TO A DOWNWIND, BUT HAD LOST ALL POWER DURING THE TURN TO FINAL APPROACH. THE AIRCRAFT IMPACTED ABOUT 1/2 MILE FROM THE AIRPORT. THE PILOT REPORTED THAT THE FUEL TANKS HAD EMPTIED. HE STATED THAT THE FUEL TANKS INDICATED ABOUT 1/4 FULL. ALSO, HE NOTED THAT HE SHOULD HAVE LOOKED INTO THE TANKS RATHER THAN RELYING ON THE GAUGES.
