Safety Recommendation A-82-044
Details
Synopsis: ON JANUARY 25, 1982, SUNDSTRAND DATA CONTROL, INC., ISSUED SERVICE BULLETIN NO. 012-0296-109, "COMMUNICATIONS COCKPIT VOICE RECORDERS/MODELS AV-557A, AV-557B, AND AV-557C/TAPE DECK HOUSING CONNECTOR CHECK." THE SERVICE BULLETIN STATED: "IT HAS BEEN DETERMINED THAT SOME CVRs (COCKPIT VOICE RECORDERS) WERE MANUFACTURED WITH CONNECTORS THAT CONTAIN SPLIT-RING, RATHER THAN FULL-RING SOCKETS. USING CONNECTORS WITH SPLIT-RING SOCKETS MAY CAUSE CVRs TO OPERATE INTERMITTENTLY, GIVE ERRONEOUS SELF TEST INDICATIONS, AND CONTRIBUTE TO SENSOR OR TAPE-OFF REEL PROBLEMS." THE SERVICE BULLETIN INSTRUCTED OWNERS OF THE CVRs HOW TO EXAMINE THEM FOR THE TYPE OF CONNECTOR SOCKET USED, AND INSTRUCTED THEM TO CONTACT THE FACTORY FOR REPLACEMENT OF THE SPLIT-RING SOCKETS. THESE TYPE CVRs ARE INSTALLED ON SUCH AIRCRAFT AS THE BOEING 727, 737, 747, AND THE DOUGLAS DC-9 AND DC-10.
Recommendation: SINCE A CVR WILL NOT OPERATE PROPERLY WITH A SPLIT-RING CONNECTOR AND BECAUSE OF THE IMMENSE VALUE OF THE CVR RECORD IN AIRCRAFT ACCIDENT INVESTIGATIONS, THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: DISSEMINATE IMMEDIATELY THE CONTENTS AND INTENT OF THIS SAFETY RECOMMENDATION LETTER TO THE CIVIL AVIATION AUTHORITIES OF FOREIGN COUNTRIES HAVING JURISDICTION OVER AIRCRAFT USING THE SUBJECT SUNDSTRAND COCKPIT VOICE RECORDERS.

Safety Recommendation History
From: NTSB
To: FAA
Date: 1/6/1984
Response: The Safety Board notes that foreign civil aviation authorities were informed of the problem and of a solution through the issuance of AD 83-16-01. Safety Recommendation A-82-44 has been placed in a "Closed--Acceptable Action" status, based on the issuance of the AD and the Board's discussion of this recommendation in its January 3, 1982, letter to the FAA.

Response: FAA LETTER: ON JULY 28, 1983, THE FAA ISSUED AIRWORTHINESS DIRECTIVE (AD) 83-16-01 (COPY ENCLOSED).

From: FAA
To: NTSB
Date: 11/15/1982
Response: FAA LTR: THE FAA HAS REVIEWED ITS POSITION AND YOUR COMMENTS IN THE DISSEMINATION OF THE BOARD'S INFORMATION ON SUNDSTRAND COCKPIT VOICE RECORDERS TO THE CIVIL AVIATION AUTHORITIES OF FOREIGN COUNTRIES. THE RESPONSIBILITY FOR THE DISSEMINATION OF THIS TYPE OF RECOMMENDATION IS WITHIN THE AUTHORITY OF THE SAFETY BOARD AND IS INAPPROPRIATE FOR THE FAA. ON THOSE OCCASIONS WHERE IMMEDIATE ACTION IS REQUIRED IN THE INTEREST OF SAFETY, THE FAA WILL TAKE THE NECESSARY STEPS THROUGH EXISTING CHANNELS TO INFORM FOREIGN OPERATORS (THROUGH THEIR RESPECTIVE AIRWORTHINESS AUTHORITIES) NORMALLY BY ISSUING AN AD.

From: NTSB
To: FAA
Date: 9/15/1982
Response: In the past, the FAA has disseminated safety recommendation information to civil aviation authorities of foreign countries upon request of the Safety Board. Your response to Safety Recommendation A-82-44 appears to involve a change in FAA policy. We ask you to reconsider your position in this matter. The Safety Board believes that FAA is in the best position, as a practical matter, to disseminate such information. We believe that any confusion as to whether Safety Board recommendations carry the mandatory authority of an FAA airworthiness directive can easily be assuaged by including a statement in the transmittal letter stating that the Safety Board's Safety Recommendations are being forwarded in the interest of timely distribution of safety information and are currently being evaluated by the FAA and that recipients will be informed of any airworthiness directives issued as a result of the recommendations. We also believe that the potential for even more confusion exists were foreign airworthiness authorities to begin to receive safety information from two separate and unrelated U.S. government agencies; confusion can best be minimized by having the FAA alone disseminate safety recommendation information to foreign authorities. We request the FAA to reconsider its response to Safety Recommendation A-82-44. We will hold this recommendation in an "Open--Unacceptable Action" status, pending the FAA's further response.

Response: FAA LTR: IN ITS VIEW OF RECOMMENDATION A-82-44, THE FAA HAS CONCLUDED THAT THE RESPONSIBILITY FOR THE DISSEMINATION OF A RECOMMENDATION OF THIS TYPE IS WITHIN THE AUTHORITY AND RESPONSIBILITY OF THE SAFTY BOARD. DISSEMINATION TO FOREIGN AIRWORTHINESS AUTHORITIES OF NTSB RECOMMENDATIONS WHICH SPECIFICALLY CALL FOR THIS TYPE OF ACTION IS INAPPROPRIATE FOR THE FAA. THERE HAVE BEEN OCCASIONS WHEN WE HAVE FELT THAT IMMEDIATE TRANSMITTAL OF SAFETY BOARD RECOMMENDATIONS TO EITHER U.S. OPERATORS OR FOREIGN OPERATORS (THROUGH THEIR RESPECTIVE AIRWORTHINESS AUTHORITIES) WAS IN THE INTEREST OF SAFETY. HOWEVER, IN SOME CASES WHERE THE BOARD HAS TASKED THE FAA TO DISSEMINATE AN NTSB RECOMMENDATION TO FOREIGN OPERATORS, UNNECESSARY CONFUSION HAS ARISEN AS TO WHETHER THE NTSB RECOMMENDATION(S) HAD THE MANDATORY AURA OF AN FAA AIRWORTHINESS DIRECTIVE. IT IS THEREFORE OUR POSITION THAT IF THE BOARD WISHES ITS RECOMMENDATIONS TRANSMITTED TO ANYONE OTHER THAN THOSE OVER WHICH WE HAVE REGULATORY AUTHORITY THE BOARD SHOULD ADDRESS AND DISSEMINATE ITS RECOMMENDATIONS WITHIN ITS OWN ADMINISTRATIVE SYSTEM.
