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.

The pilot reported that he had contacted the fixed base operator the day prior to the accident to check on the condition of the grass airstrip, and was told that airplanes had departed and landed on the grass airstrip during the day. The pilot called the fixed base operator on the morning of the accident but no one answered the phone. The pilot was unaware that it had rained at the airstrip during the night. He over flew the grass airstrip prior to landing and did not observe any standing water or signs of ground softness, so he landed on the grass strip. During landing roll, the main landing gear sank into a wet, soft area of the airstrip, and the airplane nosed over.

NTSB Probable Cause

The pilot elected to land on a grass airstrip that was unsuitable for landing due to the wet, soft runway conditions. The wet, soft runway were factors.
