## Sequence of events

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

- Loss of engine power(total) - mech failure/malf, takeoff - initial climb
  - fuel system - improper (cause)
  - maintenance,installation - improper, other maintenance personnel (cause)
- Forced landing, landing - flare/touchdown
- Gear collapsed, landing - flare/touchdown
  - landing gear,nose gear assembly - overload (contributing factor)
  - landing gear,main gear strut - overload (contributing factor)

## Analysis

THE LEFT ENGINE QUIT AT 400 FEET AFTER TAKEOFF. AFTER THE ACCIDENT FUEL WAS FOUND DRAINING FROM THE RIGHT TANK FILLER OPENING. THE ACFT WAS LEVELED AND THE ENGINE STARTED WITH BOOST PUMP AND PUMPING THROTTLE. THE ENGINE WAS STARTED TWICE BUT WOULD NOT CONTINUE TO RUN EVEN AFTER FUEL WAS ADDED. FUEL VENTS AND LINES WERE OPEN. THE FUEL SYSTEM WAS FOUND NOT TO BE COMPATIBLE WITH THE FUEL SELECTOR PLACARDS, VALVE POSITIONS AND PLUMBING AS INSTALLED. ACFT RECORDS DID NOT INDICATE ANY CHANGES OR REROUTING OF THE FUEL SYSTEM. WITH ENGINES RUNNING AND BOTH ELECTRIC BOOST PUMPS OPERATING, UNCOVERING OF EITHER RIGHT OR LEFT WING TANK OUTLETS COULD INDUCE AIR INTO THE FUEL SYSTEM WHICH WOULD REQUIRE PURGING PRIOR TO NORMAL ENGINE OPERATION.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

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.
