Probable cause

The inherent limitations of the see-and-avoid concept of separation of aircraft operating under visual flight rules that precluded the pilots of the MU-2 and the PA-32 from recognizing a collision hazard and taking actions to avoid the midair collision. Contributing to the cause of the accident was the failure of the MU-2 pilot to use all the air traffic control services available by not activating his instrument flight rules flight plan before takeoff. Also contributing to the cause of the accident was the failure of both pilots to follow recommended traffic pattern procedures, as recommended in the airman's information manual, for airport arrivals and departures. (NTSB report AAR-93/05)

Analysis

The PA-32, N82419, had been receiving ATC radar services en route to the Greenwood muni arpt. Radar services were terminated 3 mi from the arpt. The MU-2, N74FB, had just taken off from the arpt, and had reported to ATC in anticipation of receiving his IFR clearance. The flight had not yet been identified on radar. The two airplanes collided aprx 2 mi from the arpt at 2,100 ft MSL. The collision took place just outside and to the east of the indianapolis airport radar service area (arsa). The MU-2 track was 066 deg, and the PA-32 track was 174 deg. The pax/plt on the PA-32 took control of the airplane & was able to make a controlled landing. Guidance for traffic pattern operations & recommended arrival and departure procedures is found in the airman's information manual.
