Safety Recommendation A-79-100
Details
Synopsis: THE NATIONAL TRANSPORTATION SAFETY BOARD HAS COMPLETED ITS DETERMINATION OF PROBABLE CAUSE AND FINAL REPORT ON THE AMERICAN AIRLINES DC-10 ACCIDENT IN CHICAGO ON MAY 25, 1979. THE SAFETY BOARD'S ANALYSIS OF THE EVIDENCE, AND RECOMMENDATIONS SUBMITTED TO THE BOARD BY THE OTHER PARTIES WHO PARTICIPATED IN THE INVESTIGATION AND PUBLIC HEARING, HAVE IDENTIFIED SEVERAL AREAS WHICH WE BELIEVE REQUIRE THE FEDERAL AVIATION ADMINISTRATION'S EARLY ATTENTION.
Recommendation: THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: INITIATE AND CONTINUE STRICT AND COMPREHENSIVE SURVEILLANCE EFFORTS IN THE FOLLOWING AREAS: (A) MANUFACTURER'S QUALITY CONTROL PROGRAMS TO ASSURE FULL COMPLIANCE WITH APPROVED MANUFACTURING AND PROCESS SPECIFICATIONS; AND (B) MANUFACTURER'S SERVICE DIFFICULTY AND SERVICE INFORMATION COLLECTION AND DISSEMINATION SYSTEMS TO ASSURE THAT ALL REPORTED SERVICE PROBLEMS ARE PROPERLY ANALYZED AND DISSEMINATED TO USERS OF THE EQUIPMENT, AND THAT APPROPRIATE AND TIMELY CORRECTIVE ACTIONS ARE EFFECTED. THIS PROGRAM SHOULD INCLUDE FULL REVIEW AND SPECIFIC FAA APPROVAL OF SERVICE BULLETINS WHICH MAY AFFECT SAFETY OF FLIGHT.

Safety Recommendation History
From: NTSB
To: FAA
Date: 5/17/1983
Response: The safety board notes that the only action taken by faa with regard to this recommendation was the revision to order 8120.2 which was published april 30, 1979. This revision clarified the principal inspector's responsibility at assigned manufacturing facilities and placed emphasis on improved surveillance techniques of quality control. The safety board considers this action and appropriate implementation by inspectors to satisfy the intent of part (a) to the recommendation. The safety board does not view faa actions as responsive to part (b). In fact, your response of october 5, 1982, appears to be in direct conflict with the assessed need for action stated in then administrator bond's response of march 20, 1980. That response indicated that the faa's analysis of the regulatory requirements of far 21.3, 37.17, 121.703, 121.705, 135.413, 135.415, and 145.163 concerning service difficulty re- porting reveals need for revision and a regulatory project is in process. . . . the safety board believes that faa's failure to act will continue to deny industry a significant safety benefit from effective use of in-service experience. Accordingly, the safety board is classifying safety recommendation a-79-100 as closed--unacceptable action.

From: FAA
To: NTSB
Date: 10/5/1982
Response: FAA LETTER: IN THE FAA LETTER DATED MARCH 20, 1980, WE INFORMED THE BOARD THAT A REVISION TO ORDER 8120.2 WAS PUBLISHED APRIL 30, 1979. THE REVISION ACCOMPLISHED THE INTENT OF SAFETY RECOMMENDATION A-79-100(A). IN THAT LETTER WE ALSO STATED AN ANALYSIS WAS BEING PERFORMED ON THE FEDERAL AVIATION REGULATIONS CONCERNING SERVICE DIFFICULTY REPORTING. THE FAA HAS SINCE DETERMINED THAT ADDITIONAL REPORTING REQUIREMENTS WOULD CAUSE AN ECONOMIC BURDEN WITHOUT YIELDING A CORRESPONDING INCREASE IN SAFETY BENEFITS. ACCORDINGLY, THIS REGULATORY PROJECT HAS BEEN WITHDRAWN.

From: NTSB
To: FAA
Date: 6/7/1982
Response: Your reply indicated that actions to fulfill these recommendations are in progress. Therefore, these recommendations will remain classified as open--acceptable action until the safety board is advised that the actions have been completed.

From: FAA
To: NTSB
Date: 6/10/1981
Response: FAA LTR: INFORMATION REGARDING THIS RECOMMENDATION, WHICH HAS BEEN CLASSIFIED IN AN "OPEN - ACCEPTABLE ACTION" STATUS, WILL BE PROVIDED AS WE COMPLETE THESE ACTIONS.

From: NTSB
To: FAA
Date: 6/13/1980
Response: The measures outlined in your response to initiate and continue surveillance in the recommended areas were positive and comprehensive. This recommendation will be classified open--acceptable action until the regulatory revisions concerning service difficulty reporting and procedural revisions for manufacturer service document approval are evaluated by our staff.

Date: 3/20/1980
Response: FAA LTR: COMMENT ON A-79-100(A): A COMPREHENSIVE REVISION TO ORDER 8120.2 WAS PUBLISHED APRIL 30, 1979. THIS REVISION PLACES INCREASED EMPHASIS ON IMPROVED SURVEILLANCE TECHNIQUES FOR SAFETY OF FLIGHT PARTS; PROVIDES FOR MORE EFFECTIVE UTILIZATION OF INSPECTORS IN AREAS AFFECTING SAFETY; CLEARLY DEFINES THE PRINCIPAL INSPECTOR'S RESPONSIBILITY AT ASSIGNED MANUFACTURING FACILITIES, EXPANDS ON PROCESS CONTROL METHODS, AND OTHER RELATED CHANGES INVOLVING IMPROVED SURVEILLANCE METHODS. COMMENT ON A-79-100(B): THE FAA ACCEPTS THIS RECOMMENDATION AND HAS THE FOLLOWING ACTION UNDERWAY: (1) ANALYSIS OF THE REGULATORY REQUIREMENTS OF FAR 21.3, 37.17, 121.703, 121.705, 135.413, 135.415, AND 145.163 CONCERNING SERVICE DIFFICULTY REPORTING REVEALS NEED FOR REVISION AND A REGULATORY PROJECT IS IN PROCESS. (2) UPON ESTABLISHMENT OF ADEQUATE REVISION, OUR PROGRAM OF SURVEILLANCE WILL BE CONTINUED WITH EMPHASIS ON AMENDED REGULATORY REQUIREMENTS. (3) ALSO, THE FAA HAS UNDER DEVELOPMENT, WITH PARTICIPATION BY NTSB, AN AVIATION SAFETY ANALYSIS PROGRAM IN ORDER TO IMPLEMENT AN IMPROVED NATIONWIDE SAFETY ANALYSIS SYSTEM. THIS PROGRAM INCLUDES CONSIDERATION OF SERVICE DIFFICULTIES AND THE ANALYSIS AND DISSEMINATION OF SUCH INFORMATION. (4) WE HAVE PREPARED AND ORDER TO ESTABLISH REVISED PROCEDURES FOR FAA APPROVAL OF MANUFACTURER SERVICE DOCUMENTS. THIS ORDER AND ASSOCIATED ADVISORY CIRCULAR HAVE BEEN PREPARED IN DRAFT FORM.
