Aviation safety reports, made easier to study
NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.
The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.
The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

WPR12CA103
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.
NTSB Probable Cause
The pilot did not reduce the airplane’s descent rate prior to the landing flare/touchdown, which resulted in a hard landing.
Full Narrative
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.
