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.

CEN09CA452

The pilot had completed the aerial application of a field and was planning to spray another agricultural field when the airplane experienced a partial loss of engine power. The pilot stated that when he applied engine power while executing a climbing right turn over the field, the engine lost power. His attempts to increase power with the throttle further reduced engine power. The pilot then executed a forced landing on a butte, which resulted in substantial damage to the airplane.

NTSB Probable Cause

The loss of engine power for undetermined reasons while maneuvering at low altitude.

Full Narrative

The pilot had completed the aerial application of a field prior to spraying another agricultural field where the airplane experienced a partial loss of engine power. The pilot stated that when he applied engine power while executing a climbing right turn over the field, the engine lost power. Additional increases of the throttle control further reduced engine power. The pilot stated that had he not changed or reduced the throttle control setting, the engine would have not lost power. The pilot then executed a forced landing on a butte, which resulted in substantial damage to the airplane. The pilot was uninjured. No mechanical anomalies relating to the airplane were reported.
