## Probable cause

FAILURE OF THE ENGINE IMPELLER.  THE DITCH IN THE EMERGENCY LANDING AREA WAS A RELATED FACTOR.

## 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
  - eng assembly,blower/impeller/integral supercharger - failure,total (cause)
- Forced landing, descent - emergency
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - ditch (contributing factor)
- Nose over, landing

## Analysis

JUST AFTER LIFTOFF, THE ENG LOST ALL POWER & THE PLT JETTISONED HIS LOAD OF HERBICIDE. HE LANDED STRAIGHT AHEAD, BUT THE ACFT HIT A DITCH & NOSED OVER, THEN BURST INTO FLAMES.  THE PLT SUSTAINED A BROKEN FOOT, BUT EXTRICATED HIMSELF BEFORE THE FUEL TANKS EXPLODED. AN EXAM OF THE ENG REVEALED THE IMPELLER BEARING HAD FAILED.
