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.

During the takeoff roll with an air density altitude near 7,400 feet, the pilot reported that the takeoff roll "seemed normal with a bit longer requirement as expected for high temperatures conditions". The pilot reported that after takeoff the climb performance was "low". He stated that the wind shifted direction during the initial climb; he maneuvered the airplane into the wind, and to avoid power transmission line wires and a highway by "gradual right turning". While maneuvering, the airplane settled into a "mushing descent" and impacted terrain. The pilot reported there were no pre-impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation. During the impact with terrain the airplane sustained substantial damage to the left wing and empennage.

NTSB Probable Cause

The pilot's failure to maintain adequate airspeed, which resulted in the airplane exceeding its critical angle of attack while maneuvering and a subsequent aerodynamic stall.

Full Narrative

During the takeoff roll with an air density altitude near 7,400 feet, the pilot reported that the takeoff roll "seemed normal with a bit longer requirement as expected for high temperatures conditions". The pilot reported that after takeoff the climb performance was "low". He stated that the wind shifted direction during the initial climb; he maneuvered the airplane into the wind, and to avoid power transmission line wires and a highway by "gradual right turning". While maneuvering, the airplane settled into a "mushing descent" and impacted terrain. The pilot reported there were no pre-impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation. During the impact with terrain the airplane sustained substantial damage to the left wing and empennage. The pilot reported as a recommendation that "it is far better to engage the ground in somewhat of a controlled condition rather than to act with reactionary mismanagement of control inputs to the point of stalling and falling".
