Probable cause
The air traffic controllers’ failure to adhere to required radar identification procedures, which resulted in loss of separation between the departing Boeing 757 and three other airplanes. Contributing to the incident was the pilots’ inadequate preflight checks, which resulted in the airplane departing with an inoperative transponder.
