Aircraft Accident/Incident Report
Ft. Leavenworth, Kansas 66027
Saturday, March 25, 2000 17:30 CST
NTSB Narrative Summary Released at Completion of Accident
N9570E, an Aeronca 11AC, was practicing touch and go landings on runway 15. The airplane touched down and the pilot was transitioning the airplane for takeoff when it was struck from behind by N51933, an EAA Biplane P2, which landed on the same runway. N9570E was not equipped with a radio. N51933 was equipped with a radio and the pilot reported he made position reports in the traffic pattern. Both airplanes were tailwheel equipped. The pilot of N51933 reported that he looked for other airplanes in the traffic pattern and did not see any. The pilot of N51933 reported the accident may have been prevented had he not made a short final approach and if he had entered the traffic pattern on downwind instead of on a base leg.
NTSB Probable Cause Narrative
the pilot of N51933 did not see and maintain clearance from N9570E. A factor associated with the accident was the pilot of N51933's restricted forward visibility during the landing due to the tailwheel configuration. An additional factor was the pilot of N51933 entered the traffic pattern on base leg and flew a short final approach which reduced his ability to look for other traffic.
