Event Sequence
Two airplanes were taxiing head-on on the same east-west taxiway. The Cessna 182, taxiing east, observed the Great Lakes 2T-1A biplane, which was equipped with a tailwheel and was executing S-turns on the taxiway. The Cessna pilot believed the biplane pilot had seen her aircraft. As the distance between the aircraft decreased, the Cessna pilot reduced speed and moved to the right side of the taxiway, planning a wing tip to wing tip passage.
The westbound biplane then performed an S-turn to the left, directing its path toward the Cessna. In response, the Cessna pilot turned right and exited the paved surface into the dirt area adjacent to the taxiway. Despite this evasive maneuver, the two aircraft collided.
Post-Collision Information
After the collision, the biplane pilot informed airport officials that he had not seen the Cessna during the taxi. The incident occurred as the sun was setting, which may have affected visibility.
Aircraft Details
The Cessna 182 is a single-engine, high-wing general aviation airplane. The Great Lakes 2T-1A is a two-seat, open-cockpit biplane with a tailwheel configuration. No specific registrations or additional aircraft identification were provided in the original report.
