The NTSB's narrative for the Classic Aircraft CORP WACO YMF final · quoted from the NTSB record

The pilot receiving instruction and flight instructor of a single engine low wing airplane were completing a preflight engine run-up in the designated run-up area. The pilot of a tailwheel-equipped biplane after landing was cleared by the tower controller to taxi to the company hangar. The pilot of the biplane stated that while taxiing, he failed to make S-turns to improve his forward visibility due to the tailwheel configuration. The pilot of the biplane reported that he never saw the other airplane until making contact. The flight instructor stated that by the time they saw the biplane, there was not enough time to take evasive action before impact. The low wing airplane sustained substantial damage to the right wing, and the biplane sustained substantial damage to the lower right wing and wing struts. Both airplanes’ pilots reported that there were no preaccident mechanical failures or malfunctions with their corresponding airplanes that would have precluded normal operation.

The complete narrative as the NTSB published it. The NTSB's docket holds the report as a PDF and any photographs, statements and other documents from the investigation.

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 CEN26LA145.
