## Probable cause

The pilot's failure to abort the takeoff.  A berm at the end of the runway was a factor.

## Sequence of events

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

- In flight collision with terrain/water, takeoff - roll/run
  - terrain condition - dirt bank/rising embankment (contributing factor)
  - aborted takeoff - not performed, pilot in command (cause)

## Analysis

In a written statement the pilot reported that the airplane's engine sounded smooth, but was not as loud as "normal" during the takeoff roll.  He reported that the tail was lifted from the runway surface at the "normal" point, but sufficient speed for takeoff was not obtained at the "normal" liftoff point.  The pilot reported that, "After running the entire length" of the 2,200 ft grass strip he was able to liftoff, however he was unable to "sustain flight" and the aircraft collided with a 4-foot bank at the departure end of the runway.    The aircraft came to rest approximately 100 yards from the departure end of the runway.

## Flight crew

As NTSB recorded them. NTSB leaves out names.

- Pilot; age 43; commercial; airplane ratings: multi-engine sea, single-engine land; instrument ratings: airplane; medical: class 1; flight hours: 3,063 total, 1,927 in this make and model, 113 in the last 90 days, 36 in the last 30 days

## Weather

- Conditions: Visual (VMC), Day

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.
