## Probable cause

PIC'S FAILURE TO USE ALL OF THE AVAILABLE RUNWAY. A FACTOR WAS THE HIGH DENSITY ALTITUDE.

## 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
  - weather condition - high density altitude (contributing factor)
  - all available runway - not used, pilot in command (cause)
  - aborted takeoff - delayed, pilot in command
- On ground/water collision with object, takeoff - aborted
  - object - vehicle

## Analysis

THE FIELD ELEVATION WAS 1,537 FEET AND THE DENSITY ALTITUDE WAS 3,700 FEET. THE RUNWAY WAS 4,220 FEET LONG BUT THE PILOT DEPARTED FROM AN INTERSECTION AND HAD ONLY 1,584 FEET OF RUNWAY AVAILABLE. A WITNESS SAID THE AIRPLANE LIFTED OFF IN A NOSE HIGH ATTITUDE AND NEVER GOT ABOVE 30 FEET BEFORE IT STARTED BACK DOWN. THE PILOT SAID HE WAS TRYING TO LAND THE AIRPLANE BUT WAS NOT ABLE TO GET THE AIRPLANE STOPPED BEFORE IT HIT A ROADWAY CURB, AND THEN A PICKUP-TRUCK.

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.
