The NTSB's narrative final · quoted from the NTSB record
The pilot reported he had just completed an agricultural application pass and had entered a turn to setup for the next pass, when he heard a “pop” from the engine and felt the airplane slow down. His efforts to restore engine power were not successful. He dumped the application load and executed a forced landing to a road. After touching down, he maneuvered the airplane to avoid a tractor parked along the side of the road. Unfortunately, the left wing struck the sugar cane crop adjacent to the road causing damage to the lower wings, wing struts, and landing gear. A postaccident examination of the airframe and engine did not identify any preimpact anomalies consistent with an inability of the engine to produce rated power.

About this page
Everything above comes from the NTSB's public accident database: the narrative, probable cause and findings are the NTSB's own words, and the coded tables behind its report (pilot, aircraft, flight, weather, injuries, sequence of events) are written out in plain English. Pilots' ages, home towns and medical details are left out on purpose. The docket at the NTSB holds the report as a PDF and the investigation's photographs and documents. This site never names pilots, passengers or anyone else involved. A preliminary report describes what is known soon after the event and can change; the final report, with the probable cause, usually follows one to two years later and this page is refreshed when it does. Case number CEN24LA364.
