The NTSB's narrative final · quoted from the NTSB record
The pilot of the tailwheel equipped biplane reported that, during a landing roll on runway 26R, the left wing “dipped” and that he applied right aileron to counteract. The pilot stated that the airplane began to turn to the right and that, despite the application of full left rudder, left brake, and a brief application of power, he was unable to correct the movement. The lower left wing subsequently struck the ground. The airplane then veered sharply to the right, exited the runway, and the left main landing gear collapsed as the airplane came to rest upright. Postaccident examination of the airplane revealed that the fuselage was structurally damaged. The left rudder/tailwheel cable idler arm was found fractured. Examination of the two pieces of fractured left rudder/tailwheel cable idler arm revealed that the fracture progressed though the section due to a monotonic bending load. It’s likely that the fracture occurred during the pilot’s attempt to counteract the airplane’s movement to the right when directional control was lost. The airport’s automated weather observation station reported that, about 4 minutes after the accident, the wind was calm. However, the pilot reported that while on short final to the runway, the air traffic control tower controller reported wind was from 270° at 4 knots.

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 WPR20LA226.
