Cessna 172R crashes on approach to Runway 28 due to wind shear (N4946Z)

Williamson, NY, US

On December 6, 1992, a Piper PA-22-108 (registration N4946Z) operated by Williamson Flying Club, Inc. was involved in an aviation accident near Williamson, NY. Investigators recorded the probable cause as: The pilot's failure to maintain aircraft control during final approach in gusty wind conditions, which resulted in a loss of altitude and collision with a snow bank. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A Cessna 172R lost altitude during final approach in gusty crosswinds, striking a snow bank and sliding down the runway before being destroyed by fire.

What happened

The aircraft was established on final approach to Runway 28 under challenging weather conditions. The wind was blowing from 230 degrees at 20 knots, with gusts reaching up to 28 knots. As the airplane descended toward the runway threshold, it experienced a sudden loss of altitude. The pilot attempted to maintain control, but the aircraft struck a snow bank located approximately 6 to 10 feet from the approach end of the runway.

Upon impact, the nose strut collapsed as the airplane pitched over. The aircraft then slid along the surface for roughly 50 feet down the runway before coming to a stop. Immediately following the collision, a post-impact fire broke out and completely consumed the aircraft. No further details regarding injuries or fatalities were provided in the source text.

The investigation

The available source material does not contain specific investigative findings regarding mechanical failures or pilot actions beyond the immediate sequence of events described above. The focus remains on the environmental conditions and the physical outcome of the accident.

Findings

The primary factors contributing to this accident were the gusty crosswind conditions during final approach and the resulting loss of altitude control. The presence of a snow bank near the runway threshold exacerbated the severity of the impact, leading to structural failure of the nose gear and subsequent fire damage.

Probable cause

The pilot's failure to maintain aircraft control during final approach in gusty wind conditions, which resulted in a loss of altitude and collision with a snow bank.
