## Probable cause

THE PILOT'S FAILURE TO MAINTAIN DIRECTIONAL CONTROL DURING LANDING. CONTRIBUTING FACTORS WERE THE GUSTY CROSSWIND CONDITIONS.

## 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
  - weather condition - crosswind (contributing factor)
  - weather condition - gusts (contributing factor)
  - directional control - not maintained, pilot in command (cause)
  - ground loop/swerve - inadvertent, pilot in command
- Main gear collapsed, landing - roll
  - landing gear,main gear - overload

## Analysis

THE PILOT REPORTED HE LOST CONTROL DURING A CROSSWIND LANDING, AND THE LEFT GEAR COLLAPSED DURING THE SUBSEQUENT GROUNDLOOP. THE WINDS WERE GUSTING, AND HE REPORTED HE SHOULD HAVE PERFORMED A FLY-BY TO DETERMINE THE WIND CONDITIONS.

## 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 19891203048819A](https://openairdocs.org/incident/19891203048819A), Dec 3, 1989: Univar 1082, Rialto, CA, Substantial damage. Lost control landing in gusty crosswind. Left the runway collapsing the landing gear.

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.
