Safety Recommendation A-79-104
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: EXPAND THE SCOPE OF SURVEILLANCE OF AIR CARRIER MAINTENANCE BY: (A) REVISING 14 CFR 121 TO REQUIRE THAT OPERATORS INVESTIGATE AND REPORT TO A REPRESENTATIVE OF THE ADMINISTRATOR THE CIRCUMSTANCES OF ANY INCIDENT WHEREIN DAMAGE IS INFLICTED UPON A COMPONENT IDENTIFIED AS "STRUCTURALLY SIGNIFICANT" REGARDLESS OF THE PHASE OF FLIGHT, GROUND OPERATION, OR MAINTENANCE IN WHICH THE INCIDENT OCCURRED; AND (B) REQUIRING THAT DAMAGE REPORTS BE EVALUATED BY APPROPRIATE FAA PERSONNEL TO DETERMINE WHETHER THE DAMAGE CAUSE IS INDICATIVE OF AN UNSAFE PRACTICE AND ASSURING THAT PROPER ACTIONS ARE TAKEN TO DISSEMINATE RELEVANT SAFETY INFORMATION TO OTHER OPERATORS AND MAINTENANCE FACILITIES.

Safety Recommendation History
From: NTSB
To: FAA
Date: 5/17/1983
Response: As indicated in the discussion regarding safety recommendation a-79-100, the safety board believes that the failure to impose a reporting requirement for damage to structure or systems inflicted during maintenance seriously degrades the effective benefits of the faa's surveillance and service difficulty analysis programs. This position was apparently shared by the nrc blue ribbon panel whose report contained a virtually identical recommendation. The reversal of faa's position between march 20, 1980, and october 5, 1982, is disappointing and perplexing to the board. Since faa's position appears final, safety recommendation a-79-104 will be classified as closed--unacceptable action.

From: FAA
To: NTSB
Date: 10/5/1982
Response: FAA LETTER: THE FAA HAS RECONSIDERED THE PROPOSAL TO AMEND FAR 121.703 AND 135.413 TO INCLUDE MAINTENANCE INDUCED DAMAGE AND HAS DETERMINED THAT ADDITIONAL REPORTING REQUIREMENTS WOULD CAUSE AN ECONOMIC BURDEN WITHOUT YIELDING A CORRESPONDING INCREASE IN SAFETY BENEFITS. ACCORDINGLY, THE PROPOSALS TO AMEND SS121.703 AND 135.413 ARE NO LONGER BEING CONSIDERED, AND WE CONSIDER ACTION ON THIS RECOMMENDATION COMPLETED.

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: We appreciate your acceptance of this recommendation; however, we do have the following reservation: although the scope of the mechanical reliability reports would be expanded by the proposed regulatory revision to include maintenance-induced damage, the response does not indicate the manner in which structurally significant items, as defined by the maintenance review board, will be treated. We believe the ssi's should be included in the expanded mechanical reliability reports as indicated by recommendation a-79-103. We have classified this recommenda- tion as open-- acceptable action until a clarification is received regarding the content of the advisory circular proposed by faa in reply to a-79-103.

From: FAA
To: NTSB
Date: 3/20/1980
Response: FAA LTR: COMMENT ON A-79-104(A): WE ACCEPT THE RECOMMENDATION AND HAVE A REGULATORY PROJECT IN PROCESS THAT WILL AMEND FAR 121.703 AND 135.413 TO INCLUDE MAINTENANCE INDUCED DAMAGE, AS STATED IN RESPONSE TO NTSB RECOMMENDATION A-79-100(B). COMMENT ON A-79-104(B): WHEN THE REGULATORY PROJECT IDENTIFIED IN A-79-104(A) IS COMPLETED, APPROPRIATE FAA REVIEW PROCEDURES FOR DAMAGE REPORTS WILL BE ESTABLISHED. OF COURSE, SUCH A PROCEDURE CURRENTLY EXISTS FOR ALL DAMAGE REPORTS PRESENTLY RECEIVED UNDER EXISTING REGULATIONS AND PROCEDURES.
