Safety Recommendation A-90-132
Details
Synopsis: ON 9/8/89 N283AU, A BOEING 727-200 OPERATED AS USAIR FLIGHT 105 WAS A REGULARLY SCHEDULED REVENUE PASSENGER FLIGHT CONDUCTED UNDER 14 CODE OF FEDERAL REGULATIONS PART 121 FROM PITTSBURGH, PENNSYLVANIA (PIT), TO WICHITA, KANSAS, WITH AN EN ROUTE STOP IN KANSAS CITY, MISSOURI (MCI). FIFTY-EIGHT PASSENGERS, TWO FLIGHT CREWMEMBERS AND FOUR FLIGHT ATTENDANTS WERE ONBOARD. A FEDERAL AVIATION ADMINISTRATION INSPECTOR WHO WAS PERFORMING AN EN ROUTE INSPECTION OCCUPIED THE COCKPIT OBSERVER'S SEAT. THE FLIGHT FROM PITTSBURGH TO THE KANSAS CITY AREA WAS UNEVENTFUL. THE CAPTAIN WAS THE PILOT FLYING AND THE FIRST OFFICER WAS PERFORMING THE COMMUNICATIONS WITH AIR TRAFFIC CONTROL. USAIR 105 WAS CLEARED TO EXECUTE THE LOCALIZER BACK COURSE APPROACH TO RUNWAY 27 AT 2129:41. AT 2134:34, THE LOCAL CONTROLLER TOLD USAIR 105 "I" CAN'T TELL FOR SURE BUT IT APPEARS WE HAVE LOST THE LIGHTING ON THE SOUTH SIDE OF THE AIRPORT." THE FLIGHTCREW LATER DESCRIBED SEEING A BRIGHT FLASH ABOUT THIS TIME. SUBSEQUENT INSPECTION REVEALED THAT THE AIRPLANE STRUCK AND SEVERED FOUR ELECTRONIC TRANSMISSION CABLES, LOCATED ABOUT 75 FEET ABOVE THE GROUND, APPROXIMATELY 7,000 FEET EAST OF THE RUNWAY 27 THRESHOLD. THE FLIGHTCREW EXECUTED A MISSED APPROACH AND LANDED UNEVENTFULLY IN SALINA, KANSAS.
Recommendation: THE NTSB RECOMMENDS THAT THE NATIONAL WEATHER SERVICE AND THE FEDERAL AVIATION ADMINISTRATION: REQUIRE THE ACKNOWLEDGEMENT OF THE TRANSMISSION AND RECEIPT OF ALL WEATHER MESSAGES EXCHANGED BETWEEN AN FAA AIR TRAFFIC CONTROL FACILITY AND THE NATIONAL WEATHER SERVICE AT AIRPORTS WHERE WEATHER INFORMATION IS REGULARLY EXCHANGED BETWEEN THE TWO ENTITIES, TO INCLUDE THE TIME OF RECEIPT AND THE IDENTITY OF THE PERSON RECEIVING THE INFORMATION. FURTHER, THE EXCHANGE OF SUCH WEATHER MESSAGES SHOULD OCCUR OVER RECORDED TELEPHONE LINES OR RECORDED ELECTRONIC TRANSMISSION MEANS, WITH THE RECORDINGS RETAINED FOR A REASONABLE AMOUNT OF TIME.

Safety Recommendation History
From: NTSB
To: United States Department of Commerce, National Oceanic and Atmospheric Administration, National Weather Service
Date: 6/19/1992
Response:

From: United States Department of Commerce, National Oceanic and Atmospheric Administration, National Weather Service
To: NTSB
Date: 10/1/1991
Response: THE NWS HAS LONG-ESTABLISHED GUIDELINES FOR THE ACKNOWLEDGMENT OF WEATHER MESSAGES. THESE GUIDELINES ARE FOUND IN WEATHER SERVICE OPERATIONS MANUAL CHAPTER B-12, STANDARDS AND PROCEDURES OF BASIC WEATHER AND SYNOPTIC OBSERVATION PRORAMS AT NWS STATIONS. THE IMPLEMENTATION OF AUTOMATED SURFACE OBSERVING SYSTEMS (ASOS) OVER THE NEXT FEW YEARS SHOULD SUBSTANTIALLY ALLEVIATE THE BOARD' CONCERNS--THE NWS RECOGNIZES THAT ACKNOWLEDGMENT OF WEATHER DATA TRANSMISSIONS IS ESPECIALLY CRUCIAL IN AIRCRAFT ACCIDENT INVESTIGATIONS. WHEN SUFFICIENT LOCAL COMMUNICATIONS CIRCUITS ARE IN PLACE, BE IT RECORDED TELEPHONE LINES OR OTHER RECORDED TRANSMISSION SYSTEMS, NEWS PERSONNEL ON DUTY WILL PROVIDE ACKNOWLEDGMENT AT THE EARLIEST POSSIBLE TIME.

Response:

From: United States Department of Commerce, National Oceanic and Atmospheric Administration, National Weather Service
To: NTSB
Date: 11/25/1990
Response: (SUMMARIZED) THE NWS PUBLISHES A WEATHER SERVICE OPERATIONS MANUAL WHICH PROVIDES, SUBJECT TO CERTAIN CONDITIONS, A FRAMEWORK FOR AGREEMENT AT THE LOCAL LEVEL FOR WRITTEN ACKNOWLEDGEMENT OF WEATHER INFORMATION. THE NWS IS RELUCTANT TO INVOKE A MANDATORY REQUIREMENT FOR ACKNOWLEDGE MENT OF WEATHER MESSAGES BECAUSE THE PRIORITY OF DUTIES IS A PARTICULAR PROBLEM FOR NWS PERSONNEL WHO MAY BE ON DUTY ALONE PERFORMING BOTH SURFACE OBSERVING AND WARNING DISSEMI NATION DUTIES. THE NWS BELIEVES THE IMPLEMENTATION OF AUTO MATED SURFACE OBSERVING SYSTEMS (ASOS), WHICH WILL AUTO MATICALLY GENERATE HOURLY AND SPECIAL WEATHER OBSERVATIONS, WILL SUBSTANTIALLY ALLEVIATE THE BOARD'S CONCERNS REFLECTED IN A-90-132. ASOS IS SCHEDULED TO BECOME OPERATIONAL SOME TIME IN 1991. THE NWS WILL CONSIDER, IF REQUESTED BY THE FAA, ON A CASE BY CASE BASIS, WHETHER INDIVIDUAL OFFICES MAY BE ABLE TO UNDERTAKE THE ADDITIONAL RESPONSIBILITY OF ACKNOWLEDGING WEATHER MESSAGES IN WRITING.

From: NTSB
To: FAA
Date: 8/31/1993
Response: THE BOARD NOTES THAT THE FAA DISAGREES WITH THIS SAFETY RECOMMENDATION AND BELIEVES THAT THE CURRENT PROCEDURES FOR DISSEMINATING WEATHER INFORMATION ARE TIMELY AND ADEQUATE. HOWEVER, THE BOARD CONTINUES TO BELIEVE THAT IT IS NECESSARY TO INCLUDE IN ACKNOWLEDGEMENTS THE TIME OF RECEIPT AND THE IDENTITY OF THE PERSON RECEIVING THE INFORMATION OF ALL WEATHER MESSAGES EXCHANGED BETWEEN AN FAA ATC FACILITY AND THE NEWS, AT AIRPORTS WHERE WEATHER INFORMATION IS REGULARLY EXCHANGED.

From: FAA
To: NTSB
Date: 4/23/1993
Response: THE FAA DOES NOT AGREE WITH THIS RECOMMENDATION TO REQUIRE THAT THE EXCHANGE OF WEATHER MESSAGES BETWEEN THE AIR TRAFFIC CONTROLLERS AND THE NATIONAL WEATHER SERVICE OCCUR OVER RECORDED TELEPHONE LINES. AT STATED IN THE FAA'S LETTERS TO THE BOARD DATED DECEMBER 18, 1990, AND NOVEMBER 5, 1992, THE CURRENT PROCEDURES FOR DISSEMINATING WEATHER INFORMATION ARE TIMELY AND ADEQUATE.

From: NTSB
To: FAA
Date: 2/18/1993
Response: THE BOARD IS DISAPPOINTED THAT THE FAA BELIEVES THAT THE CURRENT PROCEDURES FOR DISSEMINATING WEATHER INFORMATION ARE TIMELY & ADEQUATE & MEET THE INTENT OF THIS RECOMMENDATION. THE BOARD AGREES THAT WHEN THE AUTOMATIC WEATHER OBSERVING SYSTEM & THE AUTOMATED SURFACE OBSERVING SYSTEM ARE IMPLEMENTED WITH THE NWS, THE INTENT OF THIS RECOMMENDATION WILL BE MET. HOWEVER, UNTIL THAT OCCURS, THE EXCHANGE OF WEATHER MESSAGES SHOULD OCCUR OVER RECORDED TELEPHONE LINES TO INCLUDE THE TIME OF RECEIPT & THE IDENTITY OF THE PERSON RECEIVING THE INFORMATION. THE BOARD REQUESTS THAT THE FAA RECONSIDER ITS POSITION ON THIS ISSUE & CLASSIFIES RECOMMENDATION A-90-132 "OPEN--UNACCEPTABLE RESPONSE."

From: FAA
To: NTSB
Date: 11/5/1992
Response: THE FAA DOES NOT AGREE WITH THIS SAFETY RECOMMENDATION. THE FAA BELIEVES THAT THE CURRENT PROCEDURES FOR DISSEMINATING WEATHER INFORMATION ARE TIMELY AND ADEQUATE AND MEET THE INTENT OF THIS SAFETY RECOMMENDATION. AS DESCRIBED IN THE FAA'S LETTER TO THE BOARD DATED DECEMBER 18, 1990, THE FAA IS IMPLEMENTING THE AUTOMATIC WEATHER OBSERVING SYSTEM AND THE AUTOMATED SURFACE OBSERVING SYSTEM THROUGH A JOINT CONTRACT WITH THE NATIONAL WEATHER SERVICE. THESE SYSTEMS WILL OBSERVE, DISSEMINATE, AND ARCHIVE WEATHER OBSERVATIONS PERIODICALLY. THE DATA WILL BE ARCHIVED IN ACCORDANCE WITH ESTABLISHED REQUIREMENTS AND DISSEMINATED TO ALL INTERESTED PARTIES BY DIRECTLY ACCESS TERMINALS OR THE WEATHER MESSAGE SWITCHING CENTER NETWORK.

From: NTSB
To: FAA
Date: 7/11/1991
Response: Safety Recommendation A-90-132 discusses the acknowledgement of the transmission and receipt of all weather messages exchanged between an FAA air traffic control facility and the National Weather Service (NWS), including the time of receipt and the identity of the person receiving the information. Further, the exchange of such weather messages should occur over recorded telephone lines or recorded electronic transmission means, and the recordings should be retained for a reasonable period of time. The FAA response states that the FAA believes that the current procedures are adequate and that the FAA is implementing the Automated Weather Observing System (AWOS) with the NWS. However, the Safety Board notes that the AWOS is not yet an operational system, that telephone lines currently used are not recorded, and that acknowledgment is not currently required. Pending further information, Safety Recommendation A-90-132 is classified as "Open--Unacceptable Response."

From: FAA
To: NTSB
Date: 12/18/1990
Response: THE FAA BELIEVES THAT THE CURRENT PROCEDURES MEET THE INTENT. ADDITIONALLY, THE FAA IS IMPLEMENTING THE AUTOMATED WEATHER OBSERVING SYSTEM (AWOS) WITH NEWS. THE AWOS WILL GATHER DATA, AS WELL AS ARCHIVING IT.
