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.

CEN12CA564

The pilot stated that he overshot the final approach to the runway and had to maneuver the airplane back to the final approach course. Because the airplane was high on the approach, he extended 30 degrees of flaps and descended at an airspeed of between 80 and 85 knots. The pilot stated that he thought that the approach was not stabilized; however, he continued the approach and landed. The pilot further stated that, during the landing roll, he thought that the airplane was being pushed by a strong tailwind and that he was unable to stop the airplane before the end of the runway. The airplane departed the runway, went down an embankment, and came to rest inverted, resulting in substantial damage to the airframe and both wings. The pilot stated that there were no preaccident mechanical malfunctions or anomalies that would have precluded normal operation.

NTSB Probable Cause

The pilot’s decision to continue the unstable approach, which resulted in a loss of control during landing and a runway excursion.

Full Narrative

The pilot was returning to the airport to land on runway 8. He stated that he overshot the final approach and had to maneuver the airplane back to the final approach course. The airplane was high on the approach so he extended 30 degrees of flaps and descended at an airspeed between 80 and 85 knots. The pilot stated that he felt that the approach was not stabilized; however, he continued the approach and landed. During the landing roll the pilot felt that he was being pushed by a strong tailwind and was unable to stop the airplane before the end of the runway. The airplane departed the runway environment to the right, went down a 65 foot embankment, and came to rest inverted, resulting in substantial damage to the airframe and both wings. The pilot stated that there were no mechanical anomalies with the airplane prior to the accident. Wind at the time of the accident was recorded as 340 degrees at 4 knots.
