Details
Synopsis: ON JULY 9, 1982, PAN AMERICAN WORLD AIRWAYS FLIGHT 759 CRASHED AFTER TAKING OFF FROM RUNWAY 10 AT NEW ORLEANS INTERNATIONAL AIRPORT, KENNER, LOUISIANA. WHEN FLIGHT 759 TOOK OFF, THERE WERE ISOLATED HEAVY SHOWERS OVER THE AIRPORT AND TO THE EAST OF THE AIRPORT ALONG THE AIRPLANE'S INTENDED DEPARTURE PATH. LOW LEVEL WIND SHEAR CONDITIONS HAD BEEN DETECTED BY THE AIRPORT'S LOW LEVEL WIND SHEAR ALERT SYSTEM (LLWSAS), AND THE SYSTEM HAD ALARMED SEVERAL TIMES, THE LAST TIME ABOUT 4 MINUTES BEFORE FLIGHT 759'S TAKEOFF. THE SYSTEM WAS NOT ALARMING AT THE TIME THE TAKEOFF CLEARANCE WAS ISSUED; HOWEVER, A WIND SHEAR ADVISORY WAS BROADCAST 2 SECONDS AFTER THE ACCIDENT.
Recommendation: THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: REQUIRE THAT AUTOMATIC TERMINAL INFORMATION SERVICE ADVISORIES BE AMENDED PROMPTLY TO PROVIDE CURRENT WIND SHEAR INFORMATION AND OTHER INFORMATION PERTINENT TO HAZARDOUS METEOROLOGICAL CONDITIONS IN THE TERMINAL AREA AS PROVIDED BY CENTER WEATHER SERVICE UNIT METEOROLOGISTS, AND THAT ALL AIRCRAFT OPERATING IN THE TERMINAL AREA BE ADVISED BY BLIND BROADCAST WHEN A NEW AUTOMATIC TERMINAL INFORMATION SERVICE ADVISORY HAS BEEN ISSUED.

Safety Recommendation History
From: NTSB
To: FAA
Date: 10/1/1985
Response: We note, that effective October 25, 1984, a reference to Center Weather Advisories (CWA) was added to paragraphs 1220 and 1230 of FAA Handbook 7210.3G and that this revision now specifies the need for the prompt collection and dissemination of CWAs by the Automatic Terminal Information Service. This amendment to the handbook satisfies Safety Recommendation A-83-17 which is classified as "Closed--Acceptable Action."

From: FAA
To: NTSB
Date: 4/2/1985
Response: FAA LTR: FAA HANDBOOK 7210.3G, PARAGRAPH 1230, REQUIRES A NEW AUTOMATIC TERMINAL INFORMATION SERVICE (ATIS) RECORDING TO BE MADE WHEN THERE IS A CHANGE IN PERTINENT DATA SUCH AS NOTAM'S/SIGMET'S/PIREP'S, ETC. WHILE CENTER WEATHER ADVISORIES (CWA) ARE NOT SPECIFICALLY MENTIONED, THEY ARE CONSIDERED DATA PERTINENT TO OPERATIONS IN THE TERMINAL AREA AND ARE REQUIRED TO BE PART OF THE ATIS. TO ALLEVIATE ANY MISUNDERSTANDING, EFFECTIVE OCTOBER 25, 1984, CWA'S WERE INCLUDED IN PARAGRAPH 1220 AND 1230 (ENCLOSURE 3).

From: NTSB
To: FAA
Date: 4/29/1984
Response: The Safety Board considers the change to FAA Handbook 7210.3F, paragraph 1230, only partly responsive to its recommendation. Hazardous weather advisories such as Center Weather Advisories (CWA's) pertinent to the terminal area provided by Center Weather Service Unit meteorologists are not currently required to be included in the Automatic Terminal Information Service (ATIS) broadcast. These advisories should be placed on ATIS and the Safety Board would not consider action on this recommendation complete without their inclusion. Pending further response from the FAA, Safety Recommendation A-83-17 will be maintained in an "Open- -Unacceptable Action" status.

From: FAA
To: NTSB
Date: 7/21/1983
Response: FAA LETTER: A CHANGE TO HANDBOOK 7210.3F, PARAGRAPH 1230, AUTOMATIC TERMINAL INFORMATION SERVICE (ATIS), EFFECTIVE AUGUST 4, 1983, REQUIRES THE APPROPRIATE CONTROLLER TO "BROADCAST ONCE ON ALL FREQUENCIES, EXCEPT EMERGENCY FREQUENCIES, TO ADVISE AIRCRAFT OF A CHANGE IN THE ATIS CODE/MESSAGE." THE HANDBOOK CURRENTLY REQUIRES "NOTAM'S AND NOTIFICATON OF PIREP'S, SIGMET'S/CONVECTIVE SIGMET'S PERTINENT TO OPERATIONS IN THE TERMINAL AREA" TO BE INCLUDED IN THE ATIS.
