## Probable cause

THE PILOT-IN-COMMAND'S FAILURE TO ADEQUATELY COMPENSATE FOR WIND CONDITIONS, AND HIS NOT MAINTAINING DIRECTIONAL CONTROL.  FACTORS WERE THE CROSSWIND AND WIND GUSTS.

## 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)
  - compensation for wind conditions - inadequate, pilot in command (cause)
  - directional control - not maintained, pilot in command (cause)
- On ground/water collision with object, landing - roll
  - terrain condition - hidden obstruction(s)
- Nose over, landing - roll

## Analysis

THE AIRPLANE LANDED ON RUNWAY 23.  THE PILOT LOST DIRECTIONAL CONTROL ON ROLL OUT, AND THE AIRPLANE EXITED THE RUNWAY TO THE LEFT.  THE AIRPLANE ENTERED A BEAN FIELD WHERE THE LEFT MAIN LANDING GEAR IMPACTED A ROCK, BROKE OFF, AND THE AIRPLANE NOSED OVER.  LOCAL WINDS WERE NOT RECORDED; HOWEVER, A REPORTING STATION 35 MILES TO THE NORTHEAST WAS REPORTING WINDS OF 280 DEGREES AT 14 KNOTS WITH GUSTS TO 25 KNOTS, FIFTEEN MINUTES AFTER THE ACCIDENT.

## 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 19920910039139A](https://openairdocs.org/incident/19920910039139A), Sep 10, 1992: Boeing A75, Ottawa, IL, Substantial damage. Lost control landing in gusty wind. Left the runway. Struck rocks and nosed over.

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.
