C/n / msn: 1
Fatalities:Fatalities: 1 / Occupants: 2
Other fatalities:0
Aircraft damage: Written off (damaged beyond repair)
Location:Englewood, CO -   United States of America
Phase: Landing
Departure airport:Peyton, CO (00V)
Destination airport:(APA)
Investigating agency: NTSB
The pilot of the RV-4, N44AZ, had made initial contact with the control tower on the west arrival frequency, and was instructed to report entering a right downwind for runway 17R, which he acknowledged. At about the same time, the pilot of the Sukhoi SU-29, N55SU, made initial contact with the control tower on the east arrival frequency and was instructed to report on a left base for runway 17L. Both pilots were subsequently cleared to land on their respective runways. Instead of landing on his assigned runway 17R, the pilot of the RV-4 landed on 17L. The SU-29 then landed on top of the RV-4. The FAA's ATC handbook advises controllers to restate the landing runway whenever there is a possibilty of a conflict with another aircraft which is using or planning to use another runway. The threshold of runway 17R is 1,800 feet beyond the threshold of runway 17L. The airport was hosting an open house at the time, and airborne flights from a 'Parade of Flight' were in progress. CAUSE: failure of the pilot of the RV-4, N44AZ, to comply with an ATC clearance by landing on the wrong runway, and the failure of the pilot of the SU-29, N55SU, to maintain an adequate visual lookout. Factors in the accident were: the failure of the air traffic controller to restate the landing runway to the pilot of the RV-4 during a critical period of flight, his failure to advise the pilot of the RV-4 that operations were being conducted on the adjacent runway, a high traffic workload which resulted from an airport open house, and a lack of coordination to accommodate the high traffic workload.
