Safety Recommendation A-76-042
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 RESEARCH TO DEVELOP EQUIPMENT AND PROCEDURES WHICH WOULD PERMIT A PILOT TO TRANSITION FROM INSTRUMENT TO VISUAL REFERENCES WITHOUT DEGRADATION OF VERTICAL GUIDANCE DURING THE FINAL SEGMENT OF AN INSTRUMENT APPROACH.

Safety Recommendation History
From: NTSB
To: FAA
Date: 8/21/1981
Response: We are satisfied that the faa/nasa research programs pertaining to the head-up display and autoland operations meet the intent of this recommendation. Safety recommendation a-76-42 is classified in a closed-acceptable action status.

From: FAA
To: NTSB
Date: 5/1/1981
Response: FEDERAL AVIATION ADMINISTRATION LTR: THE FAA IS PROCEEDING IN SEVERAL AREAS WITH THE DEVELOPMENT OF EQUIPMENT AND PROCEDURES TO PERMIT TRANSITION FROM INSTRUMENT TO VISUAL REFERENCES DURING THE FINAL SEGMENTS OF THE INSTRUMENT APPROACH. IN ADDITION, RESEARCH FOR LONGER TERM SOLUTIONS HAS BEEN EXPEDITED. THE RESULTS OF A JOINT FAA/NASA PROGRAM TO DETERMINE THE BENEFITS TO SAFETY DURING THE TRANSITION ATTRIBUTABLE TO A HEAD-UP DISPLAY OF INFORMATION ARE EXPECTED EARLY IN 1981. ADDITIONAL STUDY BY NASA OF THE CONTRIBUTION OF THE HEAD-UP DISPLAY TO AUTOLAND OPERATIONS IS PLANNED IN 1981. FURTHER UNDERSTANDING OF THE BENEFITS AND LIMITATIONS OF A HEAD-UP DISPLAY IS EXPECTED FROM FLIGHT EVALUATIONS TO BE CONDUCTED BY THE FAA IN 1981-1982 USING HEAD-UP DISPLAY-EQUIPPED AIRCRAFT. APPROVAL OF A HEAD-UP DISPLAY FOR USE ON A SUPPLEMENTAL BASIS HAS BEEN COMPLETED ON THE RECENTLY CERTIFICATED DC-9-80 AS A RESULT OF EXPERIENCE GAINED BY FAA CERTIFICATION SPECIALISTS IN THE FAA/NASA PROGRAM.
