Safety Recommendation Details
ON FEBRUARY 28, 1984, SCANDINAVIAN AIRLINES SYSTEM (SAS) FLIGHT 901, A MCDONNELL DOUGLAS DC-10-30 OF NORWEGIAN REGISTRY, WAS A REGULARLY SCHEDULED INTERNATIONAL PASSENGER FLIGHT FROM STOCKHOLM, SWEDEN, TO JOHN F. KENNEDY INTERNATIONAL AIRPORT (JFK), NEW YORK, WITH AN EN ROUTE STOP AT OSLO, NORWAY. FOLLOWING A CATEGORY II INSTRUMENT LANDING SYSTEM (ILS) APPROACH TO RUNWAY 4 RIGHT AT JFK, THE AIRPLANE TOUCHED DOWN LONG AND FAST AFTER WHICH IT ROLLED OFF THE END OF THE RUNWAY AND CAME TO REST WITH ITS NOSE PARTIALLY SUBMERGED IN A TIDAL WATERWAY ABOUT 600 FEET BEYOND THE DEPARTURE END OF THE RUNWAY. ALL OF THE 163 PASSENGERS AND 14 CREWMEMBERS EVACUATED THE AIRPLANE SAFELY, BUT WITH SOME INJURIES.
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: DIRECT AIR CARRIER PRINCIPAL OPERATIONS INSPECTORS TO REVIEW THE AIRSPEED CALLOUT PROCEDURES OF ASSIGNED AIR CARRIERS AND, WHERE NECESSARY, TO REQUIRE THAT THESE PROCEDURES SPECIFY THE ACTUAL SPEED DEVIATIONS (IN APPROPRIATE INCREMENTS, I.E., +10, +20, -10, -20, ETC.) FROM COMPUTED REFERENCE SPEEDS.

Safety Recommendation History
The Safety Board has reviewed Air Carrier Operations Bulletin (8340.17), Change 39, dated May 15, 1985, which requires principal operations inspectors to determine the adequacy of flightcrew procedures used to identify and correct flightpath deviations. The requirement for flightpath deviation callouts will help ensure that continuous vigilance of the flightpath is maintained whether or not the automatic flight control systems are being used. Safety Recommendation A-84-124 has been classified as "Closed--Acceptable Action."
FAA LTR: ENCLOSED FOR THE BOARD'S INFORMATION IS CHANGE 39, DATED MAY 15, 1985, TO FEDERAL AVIATION ADMINISTRATION ORDER 8430.17, AIR CARRIER OPERATIONS BULLETIN (ACOB). THIS CHANGE TRANSMITS ACOB NO. 8-85-2, CREWMEMBER PROCEDURES FOR DEVIATIONS IN FLIGHTPATH MANAGEMENT. THIS ACOB WAS ISSUED IN RESPONSE TO SAFETY RECOMMENDATION A-84-124.
The FAA's proposed action to publish an air carrier operations bulletin (ACOB) on this topic has the potential of complying with the intent of this Safety Recommendation. Safety Recommendation A-84-124 has been classified as "Open-- Acceptable Action," pending the Safety Board's review of the ACOB when issued.
FAA LTR: WE CONCUR WITH THIS RECOMMENDATION. THE OFFICE OF FLIGHT OPERATIONS WILL PUBLISH AN AIR CARRIER OPERATIONS BULLETIN (ACOB) TO ACCOMPLISH THE INTENT OF A-84-124. WE ANTICIPATE THAT THIS ACOB WILL BE ISSUED BEFORE MARCH 29, 1985, AND WILL TRANSMIT A COPY TO THE BOARD SHORTLY THEREAFTER.
