## Sequence of events

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

- On ground/water encounter with terrain/water, takeoff - aborted
  - terrain condition - dirt bank/rising embankment
  - aborted takeoff - delayed, pilot in command (cause)

## Analysis

THE PLT SAID THE ENG LOST POWER DURING TAKEOFF PAST MID-FIELD AND HE INITIATED AN ABORT. THE ACFT WAS UNABLE TO STOP IN THE REMAINING RWY AND COLLIDED WITH A DIRT EMBANKMENT PAST THE END OF THE RWY. THE OWNER OF THE ACFT IS A STUDENT PLT AND WAS THE PASSENGER ON THE FLT. HE SAID THE PILOT TOLD HIM THAT HE DID NOT THINK THAT THE ENG WAS DEVELOPING ENOUGH POWER. THE OWNER SAID THE ABORT WAS INITIATED JUST BEYOND MID-FIELD. HE SAID HE DID NOT HEAR ANY UNUSUAL NOISES FROM THE ENG OR REDUCTION OF RPM BEFORE THE ABORT WAS INITIATED. AN FAA INSPECTOR EXAMINED THE WRECKAGE AT THE ACDT SITE AND THE ENG WAS SUCCESSFULLY TEST RUN BY THE MANUFACTURER. NEITHER THE EXAM BY THE FAA NOR THE ENG RUN PROVIDED ANY EVIDENCE OF A ENG FAILURE OR MALFUNCTION.
