Safety Recommendation A-72-105
Details
Synopsis: ON JANUARY 9, 1971, AT APPROXIMATELY 1620 E.S.T., AN AMERICAN AIRLINES, INC., BOEING 707 AND A CESSNA 150 COLLIDED IN MIDAIR ABOVETHE TOWNSHIP OF EDISON, NEW JERSEY. THE AMERICAN AIRLINES AIRCRAFT, A REGULARLY SCHEDULED FLIGHT, WAS BEING FLOWN UNDER INSTRUMENT FLIGHT RULES AND THE CESSNA AIRCRAFT, ON A TRAINING FLIGHT, WAS BEING FLOWN UNDER VISUAL FLIGHT RULES. THE NATIONAL TRANSPORTATION SAFETY BOARD DETERMINES THAT THE PROBABLE CAUSE OF THIS ACCIDENT WAS THE INABILITY OF THE CREWS OF BOTH AIRCRAFT TO SEE AND AVOID EACH OTHER WHILE OPERATING IN A SYSTEM WHICH PERMITS VFR AIRCRAFT TO OPERATE UP TO 3,000 FEET ON RANDOM HEADINGS AND ALTITUDES IN A CONGESTED AREA UNDER CONDITIONS OF REDUCED VISIBILITY. OTHER CAUSAL FACTORS WERE THE DEVIATION OF THE AIR CARRIER AIRPLANE FROM ITS CLEARANCE ALTITUDE AND THE CONDUCTING OF STUDENT FLIGHT TRAINING IN A CONGESTED CONTROL AREA UNDER MARGINAL FLIGHT VISIBILITY CLEARANCE.
Recommendation: VISIBILITY AND SEPARATION FROM CLOUD DISTANCES SHOULD BE ASSESSED CONSERVATIVELY IN VFR OPERATIONS, AND THAT VFR FLIGHT SHOULD BE CONTINUED ONLY WHEN VISIBILITY IS UNQUESTIONABLE.
