Safety Recommendation A-76-039
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: MODIFY INITIAL AND RECURRENT PILOT TRAINING PROGRAMS AND TESTS TO REQUIRE THAT PILOTS DEMONSTRATE THEIR KNOWLEDGE OF THE LOW-LEVEL WIND CONDITIONS ASSOCIATED WITH MATURE THUNDERSTORMS AND OF THE POTENTIAL EFFECTS THESE WINDS MIGHT HAVE ON AN AIRPLANE'S PERFORMANCE.
