## Sequence of events

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

- Loss of engine power(partial) - nonmechanical, takeoff - roll/run
  - reason for occurrence undetermined (cause)
- On ground/water encounter with terrain/water, takeoff - roll/run
  - terrain condition - dirt bank/rising embankment
  - weather condition - high density altitude (contributing factor)

## Analysis

THE PILOT REPORTS THAT HE WAS TAKING OFF ON HIS THIRD AERIAL APP FLT OF THE DAY. HE SAID THE WIND WAS FROM THE NW AND VERY LIGHT AND HE WAS DEPARTING TO THE N. THE DENSITY ALT WAS CALCULATED TO BE 5,200 FT. ACCELERATION SEEMED TO BE NORMAL UNTIL ABOUT TWO THIRDS OF THE WAY DOWN THE 2,400 FT LONG, DIRT STRIP WHEN 'THE PLANE SEEMED LIKE IT SUDDENLY PICKED UP A TAIL WIND.' THE PLT DUMPED THE LOAD OF CHEM IN HOPES OF GETTING AIRBORNE BUT THE ACFT DID NOT FLY. THERE IS A TWO FT HIGH LEVY AT THE END OF THE STRIP AND WHEN THE MAIN GEAR HIT THE LEVY THE ACFT BOUNCED AIRBORNE AND THEN CRASHED. THE ENG WAS EXAMINED AFTER THE ACDT AND NO EVIDENCE WAS FOUND TO EXPLAIN THE REPORTED POWER LOSS.
