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 of the tailwheel-equipped airplane reported that, during a touch-and-go landing on a turf airstrip, he applied power for takeoff, the airplane drifted left, and he applied right aileron and left rudder. As the airplane accelerated, it began drifting farther left until it departed the runway onto the grass. The pilot reported that the airspeed was about 60 mph and that he felt he could fly out of the situation. However, he realized the airplane was approaching a hill with trees and a house too quickly and would not clear the trees. He then applied right rudder and the airplane turned 90° toward the runway and began to skid. The airplane skidded across the runway and hit a ditch. The left landing gear collapsed followed by the right, and the airplane skidded to a stop. The airplane sustained substantial damage to the left wing and fuselage. The pilot reported that there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation. A review of recorded data from the automated weather observation station located about 14 miles southwest of the accident site revealed that, at 1255, the wind was from 190° at 13 knots, gusting to 21 knots. The airplane landed on runway 17.

As the airplane accelerated it began drifting further left until it departed the runway to the left onto the grass. The pilot reported that the airspeed was about 60 mph and that he felt he could fly out of the situation. However, he realized the airplane was approaching a hill with trees and a house too quickly and would not clear the trees.

The left landing gear collapsed followed by the right, and the airplane skidded to a stop. The airplane sustained substantial damage to the left wing and fuselage. The pilot reported that there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation. A review of recorded data from the automated weather observation station located about 14 miles to the southwest, revealed that, at 1255 MDT, conditions were wind 190 degrees true at 13 knots, gusting to 21 knots. The airplane landed on runway 17.
