## Probable cause

THE PILOT'S INADEQUATE COMPENSATION FOR WIND CONDITIONS, AND HIS NOT MAINTAINING PROPER DIRECTIONAL CONTROL ON LANDING.

## 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)
  - compensation for wind conditions - inadequate, pilot in command (cause)
  - directional control - not maintained, pilot in command (cause)
  - ground loop/swerve - uncontrolled, pilot in command
- Nose over, landing - roll

## Analysis

THE OBSERVED WINDS WERE 210 DEGREES AT 16 KNOTS WITH GUSTS TO 24 KNOTS. THE CONVENTIONAL GEARED AIRCRAFT WAS LANDED ON RUNWAY 27. DIRECTIONAL CONTROL WAS LOST ON ROLL-OUT, AND THE AIRCRAFT GROUND LOOPED TO THE LEFT AND NOSED OVER.

## 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 19900617022949A](https://openairdocs.org/incident/19900617022949A), Jun 17, 1990: Boeing A75N1, Chicago/Aurora, IL, Substantial damage. Aircraft weather cocked into crosswing on landing began ground loop and nosed over as pilot used brakes to recover.

## Other investigations on N59448 (1)

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.

Probable cause: Failure by the pilot to maintain control of the aircraft during landing roll. Factors were variable winds and the pilot's lack of recent experience in make and model.
