Aviation Accident Summary WPR12CA103

Yellow Pine, ID, USA

Aircraft #1

N4894X

ROCKWELL INTERNATIONAL S-2R

Analysis

During the landing at a remote snow-covered airstrip, the airplane touched down at a high descent rate, bounced back into the air, and then touched down again on the packed snow surface. As the airplane slowed and its weight transferred from the wings to the landing gear, one main landing gear attach fitting, which had been damaged during the initial hard touchdown, allowed its associated gear leg to partially collapse. The partial collapse of the landing gear resulted in the airplane veering to the right, whereupon the right wing impacted the snow bank along the side of the runway and sustained substantial damage.

Factual Information

While landing at a remote snow-covered airstrip with about 350 gallons of fluid in the airplane's hopper, the pilot touched down at too great of a descent rate. The airplane bounced back into the air, and then touched down again on the packed snow surface. As the airplane began to slow and the airplane's weight began to be transferred from the wings to the landing gear, one main landing gear attach fitting, which had been damaged during the initial hard touchdown, allowed its associated gear leg to partially collapse. The partial collapse of the landing gear resulted in the airplane veering to the right, whereupon the right wing impacted the snow bank along the side of the runway.

Probable Cause and Findings

The pilot did not reduce the airplane’s descent rate prior to the landing flare/touchdown, which resulted in a hard landing.
