Narrative:
Flight 853 was descending from 6000 feet to 2500 feet when, at about 3550 feet, it collided with a Piper PA-28 aircraft (N7374J). The Piper was flown by a student pilot on a solo cross-country VFR flight. Visibility was 15 miles with intervening clouds.
Probable Cause:

PROBABLE CAUSE: β€œThe deficiencies in the collision avoidance capability of the Air Traffic Control (ATC) system of the Federal Aviation Administration in a terminal area wherein there was mixed Instrument Flight Rules (IFR) and Visual Flight Rules (VFR) traffic. The deficiencies included the inadequacy of the see-and-avoid concept under the circumstances of this case; the technical limitations of radar in detecting all aircraft; and the absence of Federal Aviation Regulations which would provide a system of adequate separation of mixed VFR and IFR traffic in terminal areas.”
