Probable cause

Failure of the pilot in the overtaking aircraft (N97RJ) to see-and-avoid the aircraft that had been leading (N911HG). Factors related to the accident were: the lack of ability for the pilot in the lead aircraft (911HG) to be able see other aircraft in the race, and self-induced pressure for both pilots to maneuver their aircraft in an effort to get a winning advantage.

Analysis

During an air race involving seven formula-one aircraft, two of the planes collided during a turn around a pylon. One of the aircraft was a mingess-bennett M30, N97RJ; the other was a cassuit 11M, N911HG. According to the pilot of N911HG, his aircraft was in the lead with the other planes closing. A video tape showed that N97RJ was descending & accelerating in the turn. N97RJ leveled before impact, but its prop (then its left wing) hit the right wing of N911HG. N97RJ then went out of control & crashed, but N911HG was landed successfully with its right wing & aileron damaged.
