Safety Recommendation A-76-044
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 DEVELOPMENT OF A PROGRAM LEADING TO THE PRODUCTION OF ACCURATE AND TIMELY FORECASTS OF WIND SHEAR IN THE TERMINAL AREA.

Response: FEDERAL AVIATION ADMINISTRATION LTR: WE BELIEVE OUR PROGRESS WITH THE LLWSAS SATISFIES THE INTENT OF THIS RECOMMENDATION. MOREOVER, RESEARCH PROGRAMS INITIATED BY THE FAA IN CONJUNCTION WITH THE NATIONAL SEVERE STORM LABORATORY, THE DEPARTMENT OF COMMERCE, AND NASA TO DETERMINE THE MAGNITUDE OF WINDSPEED COMPONENT CHANGES ASSOCIATED WITH THUNDERSTORMS ARE CONTINUING. ALSO, ADDITIONAL PROGRAMS BY THE FAA AND NASA WHICH ARE DESIGNED TO EVALUATE THE USEFULNESS OF AIRBORNE WEATHER RADAR TO IDENTIFY AREAS OF HAZARDOUS WIND SHEAR, AND COLLECTION AND ANALYSES OF SEVERE WEATHER WINDSPEED COMPONENT DATA FROM INSTRUMENTED TOWERS. FINALLY, WE ARE WORKING CLOSELY WITH THE NATIONAL WEATHER SERVICE IN EVALUATING THE FEASIBILITY OF RECORDING EQUIPMENT TO CONTINUOUSLY RECORD WIND DIRECTION AND SPEED AT AIRPORTS WHERE HOURLY SURFACE WEATHER OBSERVATIONS ARE MADE.
