## Sequence of events

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

- Loss of engine power(total) - nonmechanical, descent
  - mixture - improper use of, pilot in command (cause)
- Forced landing, descent
- In flight collision with terrain/water, landing - flare/touchdown
  - terrain condition - rough/uneven (contributing factor)

## Analysis

THE PLT REPORTS THAT HE WAS CRUISING AT 9,500 FT MSL WHEN HE ENCOUNTERED LOW BROKEN CLOUDS. HE DECIDED TO DESCEND BELOW THE CLOUDS TO ASSURE REMAINING VFR. THE PLT SAID HE RETARDED THE THROTTLE AND DESCENDED TO 7,000 FT MSL (1,000 FT AGL). WHEN THE THROTTLE WAS ADVANCED AT 7,000 FT THE ENG QUIT. THE PLT SAID HE SWITCHED FUEL TANKS BUT THE ENG DID NOT RESTART. AN OFF ARPT FORCED LANDING WAS NECESSARY AND THE ACFT LANDED GEAR UP IN ROCKY TERRAIN. THE PLT ALSO SAID THE ENG HAD BEEN LEANED TO BEST CRUISE AT 9,500 FT AND THE MIXTURE WAS NOT ENRICHENED PRIOR TO DESCENT OR DURING THE ATTEMPT TO RESTART THE ENG.
