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 airline transport pilot reported that he was operating his float-equipped airplane under Title 14, CFR Part 91 as part of his guiding business. He said he was departing a remote lake with four passengers after a bear viewing trip, and that he encountered a downdraft during the initial climb. In his report to the NTSB, he wrote: “there was not sufficient lake left to stop and I was unable to climb over the rising terrain.” The airplane struck terrain near the shoreline and came to rest upright. One passenger was seriously injured, and the airplane received substantial damage to the forward fuselage. The pilot indicated that there were no preaccident mechanical problems with the airplane.
NTSB Probable Cause
The pilot's decision to takeoff towards an area of rising terrain and potential downdrafts with a fully loaded airplane, which resulted in an encounter with a downdraft that exceeded the airplane's climb capability.
