## Probable cause

THE LOSS OF DIRECTIONAL CONTROL ON THE GROUND AND THE PILOT'S INADVERTENT GROUND LOOP. A FACTOR WAS THE FAILURE BY THE PILOT OF THE CONFLICTING TRAFFIC ON THE RUNWAY TO MAINTAIN PROPER TRAFFIC SEPARATION.

## Sequence of events

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

- Loss of control - on ground/water, takeoff - aborted
  - visual separation - not maintained, pilot of other aircraft (contributing factor)
  - abort - initiated, pilot in command
  - directional control - not maintained, pilot in command (cause)
  - ground loop/swerve - inadvertent, pilot in command (cause)

## Analysis

DURING THE TAKEOFF ROLL THE PILOT OBSERVED ANOTHER AIRCRAFT BEGIN A TAKEOFF FROM THE OPPOSITE DIRECTION. THE PILOT ABORTED THE TAKEOFF; HOWEVER, HE LOST CONTROL AND THE AIRCRAFT GROUND LOOPED.

## Factual narrative

On October 10, 1994, at 1230 central daylight time, an Air Tractor AT-502, N133HF, was substantially damaged during an aborted takeoff at Lamesa, Texas.  Visual meteorological conditions prevailed and no flight plan was filed for this aerial application flight.  The commercial pilot was uninjured.

During an interview conducted by a Federal Aviation Administration inspector, and in his written statement, the pilot stated that he was halfway down the runway when he aborted takeoff due to conflicting traffic in position to takeoff from the opposite direction.  During the abort, the pilot lost directional control and ground looped the aircraft.

The aircraft sustained damaged to the empennage, wings, and fuselage.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19941010034309A](https://openairdocs.org/incident/19941010034309A), Oct 10, 1994: Airtrc AT502, Lamesa, TX, Substantial damage. Aborted takeoff due opposite landing traffic. Lost control and ground looped.

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.
