## Sequence of events

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

- Loss of engine power(partial) - nonmechanical, takeoff - initial climb
  - fluid,fuel - contamination (cause)
  - aircraft service - improper (cause)
- Forced landing, landing - flare/touchdown
- On ground/water collision with object, landing - roll
  - object - vehicle (contributing factor)
  - maneuver - performed, pilot in command
  - object (contributing factor)

## Analysis

A PARTIAL LOSS OF POWER WAS EXPERIENCED DURING TAKEOFF AND A FORCED LANDING WAS MADE ON A ROAD. AS THE PILOT WAS LANDING, A CAR PULLED OUT ON THE ROAD AHEAD OF THE AIRCRAFT. WHILE MANUEVERING TO THE RIGHT TO AVOID THE CAR, THE RIGHT WING STRUCK A ROAD SIGN AND THE PLANE SWERVED INTO A DITCH. THE PILOT STATED THAT HE TOOK A FUEL SAMPLE FROM HIS FUEL TANK AND AN EXAMINATION BY AN INDEPENDENT LABORATORY REVEALED THAT IT CONTAINED FIVE PERCENT JET FUEL.
