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.

LAX08CA125
The pilot reported that both he and the passenger walked the runway and removed debris from it, including sticks and rocks, prior to takeoff. The runway had softened due to snow and water runoff and the pilot said he experienced slight sinking conditions, but it was not muddy or sloppy. The pilot elected to depart to the south in order to takeoff on a downhill slope. The pilot performed a soft field takeoff by pulling the yoke back to reduce friction from the nose wheel. About 40 miles per hour (mph), the airplane hit several ruts and slowed down. He initiated rotation at 60 mph, but could not gain sufficient altitude prior to hitting a tree at the departure end of the runway, causing substantial damage. The pilot reported that there were no mechanical malfunctions or failures of the airplane.
NTSB Probable Cause
The pilot's failure to attain and maintain an adequate airspeed during the takeoff to clear trees during the initial climb. Contributing factors were the soft and rough nature of the short runway surface.
