Incident Overview
A Cessna 172 and a de Havilland Gipsy Moth collided at an altitude of 150 feet above ground level while both aircraft were on short final approach to an uncontrolled airport. The collision occurred when the pilot of the Gipsy Moth, on base leg, failed to observe and yield the right-of-way to the Cessna, which was already established on the final approach course. The Moth pilot turned onto final approach slightly in front of and above the Cessna. Between 5 and 10 seconds later, the Moth's propeller sliced into and partially severed an outboard portion of the Cessna's right wing.
Traffic Pattern and Communications
The pilot of the Cessna had broadcast his position while on the downwind, base, and final approach legs of the left-hand traffic pattern. However, the airport had a published right-hand traffic pattern. The Gipsy Moth was not equipped with a communication radio.
Aircraft and Location
The aircraft involved were a Cessna 172 and a de Havilland Gipsy Moth. The airport was uncontrolled. No other details about the location, time, or occupants were provided in the source.
