Safety Recommendation A-76-040
Details
Synopsis: ON JUNE 24, 1975, EASTERN AIR LINES FLIGHT 66, A BOEING 727, CRASHED DURING A PRECISION INSTRUMENT APPROACH TO THE JOHN F. KENNEDY INTERNATIONAL AIRPORT, JAMAICA, NEW YORK. ONE HUNDRED AND THIRTEEN PERSONS DIED FROM THE INJURIES THAT THEY RECEIVED. THE NATIONAL TRANSPORTATION SAFETY BOARD'S INVESTIGATION OF THE ACCIDENT DISCLOSED THAT THE AIRCRAFT DEVELOPED A HIGH DESCENT RATE AS IT PASSED THROUGH OR BELOW THE BASE OF A MATURE THUNDERSTORM. THE STORM WAS ASTRIDE THE APPROACH COURSE AND APPROXIMATELY 1 MILE FROM THE END OF THE RUNWAY. THE PILOTS OF OTHER FLIGHTS WHICH PRECEDED FLIGHT66 ON THE APPROACH REPORTED THAT THEY TOO HAD ENCOUNTERED PROBLEMS IN CONTROLLING THEIR AIRCRAFT TO MAINTAIN A SAFE APPROACH PROFILE. THESE AIRCRAFT AVOIDED AN ACCIDENT POSSIBLY BECAUSE THE PREVAILING CONDITIONS WERE LESS SEVERE OR BECAUSE THE PILOTS RECOGNIZED AND RESPONDED TO THE SITUATION FASTER THAN THE PILOTS OF FLIGHT 66.
Recommendation: EXPEDITE THE PROGRAM TO DEVELOP, IN COOPERATION WITH APPROPRIATE GOVERNMENT AGENCIES AND INDUSTRY, TYPICAL MODELS OF ENVIRONMENTAL WINDS ASSOCIATED WITH MATURE THUNDERSTORMS WHICH CAN BE USED FOR DEMONSTRATION PURPOSES IN PILOT TRAINING SIMULATORS.

Safety Recommendation History
From: NTSB
To: FAA
Date: 5/22/1980
Response: The safety board is pleased to note that extensive investigationand testing by government agencies and industry groups have resulted in the development and selection of models of classic wind shears associated with thunderstorms. We are also pleased to be informed that these models are being utilized by many air carriers during initial and recurrent pilot simulator training programs. The faa's responsive actions satisfy the intent of the recommendation, which we are now classifying as closed--acceptable action.

From: FAA
To: NTSB
Date: 4/18/1980
Response: FAA LETTER: EXTENSIVE INVESTIGATION AND TESTING BY GOVERNMENT AGENCIES AND INDUSTRY GROUPS HAVE RESULTED IN THE SELECTION OF 10 MODELS OF CLASSIC WIND SHEARS ASSOCIATED WITH THUNDERSTORMS AND OTHER SHEAR PRODUCING PHENOMENON. THESE MODELS ARE AVAILABLE TO ALL INTERESTED OPERATORS AND ARE CURRENTLY UTILIZED NATIONALLY AND INTERNATIONALLY BY MANY AIR CARRIERS DURING INITIAL AND RECURRENT PILOT SIMULATOR TRAINING PROGRAMS. WIND SHEAR MODELS ARE AVAILABLE IN IBM PUNCH CARD AND COMPUTER LISTING FORMAT. THE AVAILABLE MODELS HAVE PROVIDED TANGIBLE SITUATIONS UNDER CONTROLLED CONDITIONS AND HAVE LED TO THE DEVELOPMENT OF SPECIFIC PILOT OPERATIONAL PROCEDURES TO AVOID OR COPE WITH KNOWN WIND SHEAR CONDITIONS.

Date: 7/7/1976
Response: FAA LTR: THE FAA, IN CONJUNCTION WITH NASA AND NOAA, HAS ALREADY DEVELOPED MODELS OF ENVIRONMENTAL WINDS ASSOCIATED WITH MATURE THUNDERSTORMS AND IS CURRENTLY TESTING THEM IN A PILOTED SIMULATOR. WE WILL MAKE THESE MODELS AVAILABLE TO OPERATORS OF PILOT TRAINING SIMULATORS. WE EXPECT THE MODEL TO BE AVAILABLE BY OCTOBER 1976.
