Aircraft Accident/Incident Report
Clinton, Iowa 52732
Wednesday, September 12, 2012 19:15 CDT
NTSB Narrative Summary Released at Completion of Accident
The pilot of a Great Lakes biplane was landing when the airplane struck the rear of a Varga airplane that had previously landed and was still on the runway. According to the pilot of the Great Lakes, he did not see the other airplane until the impact occurred. The Varga had completed a straight-in approach following a practice instrument approach. The Great Lakes landed using a left hand traffic pattern approach to landing. FAA regulations state that when two airplanes are approaching to land at the same airport, the airplane at the lower altitude has the right of way. The airport was a non-towered airport, and both pilots reported that they had announced their positions in the airport traffic pattern. Regulations did not prohibit the use of a straight-in approach.
NTSB Probable Cause Narrative
The pilot of the other airplane failing to adequately monitor for other aircraft while landing.
