Safety Recommendation A-82-011
Details
Synopsis: AS A RESULT OF ITS CONTINUING INVESTIGATION OF THE CRASH OF AIR FLORIDA FLIGHT 90, A BOEING 737-222 (N62AF) ON JANUARY 13, 1982, THE NATIONAL TRANSPORTATION SAFETY BOARD BELIEVES THAT IMMEDIATE CORRECTIVE ACTION IS NEEDED IN THE AREA OF COLD-WEATHER OPERATIONS PROCEDURES. THE AIRCRAFT HAD DEPARTED FROM RUNWAY 36 AT WASHINGTON NATIONAL AIRPORT IN MODERATE TO HEAVY SNOWFALL AND LOW VISIBILITY. THE AIRCRAFT FAILED TO ACHIEVE A SUFFICIENT RATE OF CLIMB, STRUCK THE 14TH STREET BRIDGE ABOUT 4,500 FEET FROM THE DEPARTURE END OF THE RUNWAY, AND CRASHED INTO OF THE POTOMAC RIVER. SEVENTY-FOUR OF THE 79 PERSONS ABOARD THE AIRCRAFT WERE KILLED EITHER ON IMPACT OR BY DROWNING, AND 4 PERSONS IN AUTOMOBILES ON THE BRIDGE WERE KILLED WHEN THE VEHICLES WERE STRUCK BY THE DESCENDING AIRCRAFT.
Recommendation: THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: DOCUMENT THE EFFECT OF ENGINE INLET PRESSURE PROBE BLOCKAGE ON ENGINE INSTRUMENT READINGS AND REQUIRE THAT SUCH INFORMATION BE ADDED TO APPROVED AIRCRAFT FLIGHT MANUALS.

Safety Recommendation History
From: NTSB
To: FAA
Date: 6/24/1986
Response: We have reviewed Air Carrier Operations Bulletin (ACOB) No. 7-82-2 Cold Weather Procedures and the FAA Publication "Winter Operations Guidance for Air Carriers." We note that both these documents emphasize the problems associated with engine inlet icing and suggested operational procedures. Also we note that the FAA's Air Transportation Division periodically advises regional Flight Standards personnel of the importance of effective winter operation training programs and recommends the review of operations manuals and training programs. These actions are responsive to the above recommendations which we have classified as "Closed--Acceptable Alternate Action."

To: NTSB
Date: 4/21/1986
Response: "...THE FAA ISSUED ACOB NO. 7-82-2 (COPY ENCLOSED) TO BRING THIS PARTICULAR PROBLEM TO THE ATTENTION OF AIR CARRIER FLIGHTCREW MEMBERS. IN ORDER TO ASSURE THAT THIS INFORMATION IS PERIODICALLY BROUGHT TO FLIGHTCREW MEMBER'S ATTENTION, IT HAS BEEN INCLUDED IN THE FAA PUBLICATION "WINTER OPERATIONS GUIDANCE FOR AIR CARRIERS." IN ADDITION, THE FAA'S AIR TRANSPORTATION DIVISION HAS BEGUN TO PERIODIC ALLY ADVISE REGIONAL FLIGHT STANDARDS PERSONNEL OF THE IMPORTANCE OF EFFECTIVE WINTER OPERATION TRAINING PROGRAMS AND TO RECOMMEND PERIODIC REVIEW OF OPERATIONS MANUALS AND TRAINING PROGRAMS WITH RESPECT TO WINTER OPERATIONS. THE FAA DOCUMENT MENTIONED ABOVE SERVES AS THE BASIC REFERENCE DOCUMENT FOR REVIEW OF WINTER OPERATION TRAINING PROGRAMS. FURTHER ENCLOSED IS A COPY OF THE MOST RECENT LETTER ISSUED BY THE FAA'S AIR TRANSPORTATION DIVISION ON THE SUBJECT OF AIR CARRIER WINTER OPERATIONS."

From: NTSB
To: FAA
Date: 4/19/1982
Response: The FAA is developing a new AC which will include a detailed review of the hazards associated with engine inlet and pressure probe icing and how to recognize it and information concerning the proper use of engine anti-ice systems. In addition, the FAA is conducting a detailed technical analysis to determine the influence of engine inlet and pressure probe icing on engine instrument readings, cross-check procedures and aircraft performance. The FAA advises that when this new AC is completed appropriate changes will be made to Flight Manuals if required for safety of flight. These actions satisfy the intent of A-82-11, which will be classified as "Open-- Acceptable Action" awaiting receipt of the new AC.

From: FAA
To: NTSB
Date: 2/22/1982
Response: FAA LTR: THE FAA IS DEVELOPING A NEW ADVISORY CIRCULAR (AC) CONCERNING THE HAZARDS ASSOCIATED WITH ENGINE INLET AND PRESSURE PROBE ICING. ALSO, THE FAA IS CONDUCTING A DETAILED TECHNICAL ANALYSIS TO DETERMINE THE INFLUENCE OF ENGINE INLET AND PRESURE PROBE ICING ON ENGINE INSTRUMENT READINGS, CROSS-CHECK PROCEDURES, AND AIRCRAFT PERFORMANCE. WHEN THIS AC IS COMPLETED, APPROPRIATE CHANGES WILL BE MADE TO FLIGHT MANUALS IF REQUIRED FOR SAFETY OF FLIGHT.
