## Probable cause

The aborted takeoff not performed by the pilot.  A contributing factor is the reported loss of takeoff performance.

## Sequence of events

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

- Loss of engine power, takeoff
  - emergency procedure - not performed, pilot in command (cause)
  - aircraft performance,takeoff capability - reduced (contributing factor)
- Overrun, takeoff
- Nose over, takeoff
- In flight collision with terrain/water, takeoff
  - terrain condition - ground

## Analysis

The aerial application airplane overran the runway into a field during takeoff.  According to the Federal Aviation Administration inspector, the pilot stated that he never reduced the throttle in an attempt to abort the takeoff from runway 11 (2,000 feet by 75, grass), which was dry and mowed at the time of the accident.  The pilot stated that he thought the engine was not developing full power because it used up the entire runway length in the takeoff attempt.  The airplane was powered by a Pratt & Whitney, R-1340-AN1, serial number 31239 engine.  No subsequent engine anomalies were reported.

## Factual narrative

The local flight was originating at the time of the accident.

According to the Federal Aviation Administration inspector, the pilot stated that he never reduced the throttle in an attempt to abort the takeoff from runway 11 (2,000 feet by 75, grass), which was dry and mowed at the time of the accident.  The airplane then overran the runway into a field at the departure end of the runway.  The pilot stated that he thought the engine was not developing full power because it used up the entire runway length in the takeoff attempt.  The airplane was powered by a Pratt & Whitney, R-1340-AN1, serial number 31239 engine.  No subsequent engine anomalies were reported.
