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.

CHI07CA152
The aircraft executed an emergency landing after takeoff. Shortly after takeoff, the pilot observed smoke coming from the left engine. As he started his turn back towards the airport, he discovered oil leaking from the inboard side of the left engine cowling. He shut down the left engine, feathered the propeller, and turned final for the runway (4,001 feet by 150 feet, asphalt). He noticed that he was too high and east of the centerline, and started making his correction while still carrying a lot of power with the right engine. As he landed, the right main gear touched first followed by the left main gear. The left main gear collapsed. The airplane then departed the left side of the runway into the grass, where the nose gear and right main gear subsequently collapsed.
NTSB Probable Cause
The pilot not obtaining proper alignment with the runway during the emergency landing after takeoff, which imparted an excessive side load on the landing gear. Factors contributing to the accident were the unstabilized approach and engine shutdown due to the oil leak.
Full Narrative
