## Probable cause

INADEQUATE COMPENSATION FOR WIND CONDITIONS BY THE PILOT AND HIS FAILURE TO MAINTAIN DIRECTIONAL CONTROL DURING THE LANDING.  THE PILOT'S INADEQUATE PREFLIGHT PREPARATION (LACK OF A WEATHER BRIEFING) AND THE WEATHER CONDITIONS WERE CONTRIBUTING FACTORS.

## Sequence of events

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

- Loss of control - on ground/water, landing - roll
  - preflight planning/preparation - inadequate, pilot in command (contributing factor)
  - weather condition - unfavorable wind (contributing factor)
  - weather condition - crosswind (contributing factor)
  - weather condition - gusts (contributing factor)
  - compensation for wind conditions - inadequate, pilot in command (cause)
  - directional control - not maintained, pilot in command (cause)
  - ground loop/swerve - uncontrolled
- On ground/water collision with object, landing
  - object - aircraft parked/standing (contributing factor)

## Analysis

DRG ARRIVAL, THE PLT MADE A STRAIGHT-IN APCH TO RWY 16 IN WINDS THAT HE ESTIMATED WERE VARIABLE AT 20 GUSTING 55 KTS. HE RPRTD THAT DRG THE LANDING ROLL, THE ACFT WAS LIFTED BY A GUST OF WIND. HE APPLIED POWER & THE ACFT SETTLED BACK ONTO THE RWY. HOWEVER, THE PLT LOST DIRECTIONAL CONTROL & THE ACFT SUBSEQUENTLY STRUCK 2 PARKED AIRPLANES BEFORE COMING TO REST.

## 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 19890814029159A](https://openairdocs.org/incident/19890814029159A), Aug 14, 1989: Conaer LA4200, Bountiful, UT, Substantial damage. Pilot lost directional control and porpoised off the runway and struck two parked airplanes.

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.
