Safety Recommendation A-82-012
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: AMEND ADVISORY CIRCULARS 91-13C, "COLD WEATHER OPERATION OF AIRCRAFT," AND 91-51, "AIRPLANE DEICE AND ANTI-ICE SYSTEMS," TO DISCUSS IN DETAIL THE EFFECTS AND HAZARDS ASSOCIATED WITH ENGINE INLET PRESSURE PROBE ICING.

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."

From: FAA
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 MEMBERS 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 PERIODICALLY 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 plans to conduct a detailed review of AC 91-13C "Cold Weather Operation of Aircraft," and AC 91-51, "Airplane Deice and Anti-Ice Systems," to determine if they require updating in areas other than that covered by the new AC on engine inlet icing. This review of AC 91-13c and AC 91-51 and the development of a new engine inlet icing AC fully satisfy the objectives of this recommendation. A-82-12 will be classified as "Open--Acceptable Alternate Action" pending receipt of the results of the review of AC 91-13c and AC 91-51.

Response: FAA LTR: THE FAA PLANS TO CONDUCT A DETAILED REVIEW OF AC 91-13C, COLD WEATHER OPERATION OF AIRCRAFT, AND AC 91-51, AIRPLANE DEICE AND ANTI-ICE SYSTEMS TO DETERMINE IF THEY REQUIRE UPDATING IN AREAS OTHER THAN THAT COVERED BY THE NEW AC ON ENGINE INLET ICING.
