- Loss of engine power, maneuvering - aerial application
  - reason for occurrence undetermined (cause)
- Loss of control - in flight, maneuvering - aerial application
  - airspeed - not maintained, pilot in command (cause)
  - stall/spin - inadvertent, pilot in command
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

AFTER MAKING A SWATH RUN THE AIRCRAFT PULLED UP TO CLEAR POWER LINES. WITNESSES STATE THAT THE ENGINE CUT OUT AND AIRCRAFT PITCHED NOSE DOWN AND BEGAN TO ROTATE. THEY STATE THAT THE ENGINE REGAINED POWER JUST PRIOR TO IMPACT. SUBSEQUENT INVESTIGATION FAILED TO REVEAL ANY MECHANICAL DISCREPANCIES THAT WOULD HAVE CONTRIBUTED TO THE ACCIDENT. CONDITIONS WERE NOT CONDUCIVE TO CARB ICE AND FUEL WAS FOUND AT THE SITE IN THE LINES LEADING TO THE ENGINE.

## 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.
