THE AIRPLANE WAS CLEARED TO TAKE OFF FOLLOWING A DELAY OF APPROXIMATELY 27 MINUTES AFTER DEICING. THE TAKEOFF ROLL WAS UNEVENTFUL, BUT FOLLOWING A RAPID ROTATION, THE AIRPLANE CRASHED OFF THE RIGHT SIDE OF RUNWAY 35 LEFT. BOTH PILOTS, 1 FLIGHT ATTENDANT, AND 25 PASSENGERS SUSTAINED FATAL INJURIES. TWO FLIGHT ATTENDANTS AND 52 PASSENGERS SURVIVED.
Recommendation: THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: UNTIL SUCH TIME THAT GUIDELINES FOR DETECTING UPPER WING SURFACE ICING CAN BE INCORPORATED INTO THE AIRPLANE FLIGHT MANUAL, ISSUE AN AIR CARRIER OPERATIONS BULLETIN DIRECTING ALL PRINCIPAL OPERATIONS INSPECTORS TO REQUIRE THAT ALL MCDONNELL DOUGLAS DC-9-10 SERIES OPERATORS ANTI-ICE AIRPLANES WITH MAXIMUM EFFECTIVE STRENGTH GLYCOL SOLUTION WHEN ICING CONDITIONS EXIST.

Safety Recommendation History
From: NTSB
To: FAA
Date: 8/31/1992
Response: ON JANUARY 3, 1992, THE FAA ISSUED AIRWORTHINESS DIRECTIVE (AD) 93-03-01 APPLICABLE TO MCDONNELL DOUGLAS DC-9-10 SERIES AIRPLANES, WHICH MET THE INTENT OF BOTH OF THESE RECOMMENDATIONS. SAFETY RECOMMENDATION A-91-124 WAS CLASSIFIED AS "CLOSED--ACCEPTABLE ACTION" ON JUNE 25, 1992, BUT SAFETY RECOMMENDATION A-88-134 WAS NOT CLOSED. IN VIEW OF THE ABOVE INFORMATION, THE SAFETY BOARD CLASSIFIES SAFETY RECOMMENDATION A-88-134 AS "CLOSED--NO LONGER APPLICABLE."

From: NTSB
To: FAA
Date: 12/11/1991
Response: In reviewing the status of open aviation safety recommendations, the National Transportation Safety Board noted that Safety Recommendation A-88-134 is classified as "Open--Unacceptable Response." As a result of its investigation of an accident on November 15, 1987, involving a Continental Airlines DC-9 at the Stapleton International Airport, Denver, Colorado, the Safety Board recommended in A-88-134 that until such time that guidelines for detecting upper wing surface icing can be incorporated into the airplane flight manual, the FAA should issue an air carrier operations bulletin directing all principal operations inspectors to require that all McDonnell Douglas DC-9-10 series operators anti-ice airplanes with maximum effective strength glycol solution when icing conditions exist. Subsequently, as a result of its investigation of an accident on February 17, 1991, involving a Ryan International Airlines DC-9 at the Cleveland-Hopkins International Airport, Cleveland, Ohio, the Safety Board issued Safety Recommendation A-91-124 asking the FAA to require in air carrier operations manuals and appropriate airplane flight manuals that flightcrews of DC-9-10 airplanes perform a visual and tactile inspection of the wing leading edge and upper surface using necessary equipment prior to departure whenever the airplane has recently encountered icing conditions. On January 3, 1992, the FAA issued Airworthiness Directive (AD) 92-03-01 applicable to McDonnell Douglas DC-9-10 series airplanes, which met the intent of both of these recommendations. Safety Recommendation A-91-124 was classified as "Closed-- Acceptable Action" on June 25, 1992, but Safety Recommendation A-88-134 was not closed. In view of the above information, the Safety Board classifies Safety Recommendation A-88-134 as "Closed--No Longer Applicable."

From: NTSB
To: FAA
Date: 11/16/1991
Response: From the accident report of Ryan International Airlines, DC-9-15, N565PC, Loss of control on takeoff from Cleveland-Hopkins International Airport in Cleveland, Ohio on February 17, 1991. The Board adopted this report on 11/16/1991. In addition the Safety Board reiterates the following safety recommendation to the FAA: A-88-134.

From: FAA
To: NTSB
Date: 1/30/1989
Response: THE FAA AGREES WITH THE INTENT OF THIS RECOMMENDATION. ON 1/19/88, THE FAA ISSUED ACTION NOTICE 8300.34, AIRCRAFT DEICING PROCEDURES, TO BRING THE CONTENTS OF ADVISORY CIRCULAR (AC) 20-117, HAZARDS FOLLOWING GROUND DEICING AND OPERATIONS IN CONDITIONS CONDUCIVE TO AIRCRAFT ICING, TO THE ATTENTION OF OPERATIONS AND MAINTENANCE INSPECTORS. ADVISORY CIRCULAR 20-117 CONTAINS INFORMATION REGARDING THE VARIABLES THAT INFLUENCE THE TIME OF EFFECTIVENESS OF FREEZING POINT DEPRESSANTS AND THE CHARACTERISTICS, CAPABILITIES, AND LIMITATIONS OF FREEZING POINT DEPRESSANT FLUIDS. ADVISORY CIRCULAR 20-117 ALSO EMPHASIZES THAT THE FREEZING POINT DEPRESSANT FLUID STRENGTH OR RATIO OF FREEZING POINT DEPRESSANT INGREDIENTS ARE SIGNIFICANT FACTORS IN DEICING PROPERTIES, AS WELL AS THE TIME THAT THE FREEZING POINT DEPRESSANT FLUID WILL REMAIN EFFECTIVE. THE FAA ALSO ISSUED AIR CARRIER OPERATIONS BULLETIN NO. 7-81-1, AIRCRAFT DEICING AND ANTI-ICING PROCEDURES, REQUESTING THAT EACH PRINCIPAL OPERATIONS INSPECTOR BECOME FAMILIAR WITH AC 20-117 AND PROVIDE A COPY OF AC 20-117 TO EACH OF THEIR CERTIFICATE HOLDERS.
