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.

CHI08CA103

The amateur-built airplane was substantially damaged during a forced landing during landing approach. The pilot reported that as he circled the airport, the engine speed went to 6,000 RPM. He stated that he pulled the power back, lowered the landing gear and increased the propeller pitch. He said that the airplane began to stall and he could not maintain altitude. He executed a forced landing to a wetland. The right wing struck the water and broke off spinning the airplane around. Subsequent examination of the controllable pitch propeller revealed that a jack screw pin had sheared allowing the prop to go to a fine pitch setting. One of the blade pitch stops also broke resulting in the blade moving into a reverse pitch position.

NTSB Probable Cause

The failure of the propeller pitch control mechanism during approach. Contributing to the accident were the inability of the pilot to maintain airspeed and altitude, and the unsuitable terrain.
