Safety Recommendation History
From: NTSB
To: FAA
Date: 3/19/1987
Response: The Safety Board has reviewed the action notice provided in your letter of January 30, 1987, and finds that it complies with the intent of this recommendation. Therefore, Safety Recommendation A-86-84 has been classified as "Closed--Acceptable Action."

From: FAA
To: NTSB
Date: 1/30/1987
Response: On November 28, 1986, the FAA issued Action Notice A8300.11 (copy enclosed) to address the restraint system issues expressed in these recommendations. This action notice requires aviation safety inspectors to ensure that air carriers have established and implemented appropriate procedures to periodically inspect crew and passenger restraint systems, and to repair or replace these systems when there is obvious damage, wear, or chafing which could degrade the integrity of the system. The action notice also instructs principal maintenance inspectors to evaluate the maintenance programs of their assigned air carriers regarding crew and passenger restraint systems, and emphasizes inspections of crew and passenger restraint systems during normal surveillance. I believe that this action satisfies the intent of these recommendations, and I consider the FAA's action to be completed.

From: FAA
To: NTSB
Date: 11/18/1986
Response: THE FAA WILL ISSUE AN ACTION NOTICE TO INSTITUTE A PROGRAM OF AIRCRAFT INSPECTION AND MAINTENANCE PRACTICE EVALUATION OF AIR CARRIERS. THE ACTION WILL INSTRUCT PRINCIPAL MAINTENANCE INSPECTORS TO EVALUATE THE MAINTENANCE PROGRAMS TO ASSIGNED CARRIERS REGARDING FLIGHT ATTENDANT RESTRAINT SYSTEMS. IN ADDITION, THE NOTICE WILL EMPHASIZE INSPECTIONS OF FLIGHT ATTENDANT RESTRAINT SYSTEMS DURING NORMAL SURVEILLANCE BY MAINTENANCE INSPECTORS. ON 11-28-86, THE FAA ISSUED AC A8300.11 TO ADDRESS THE RESTRAINT SYSTEMS ISSUES EXPRESSED IN THESE RECOMMENDATIONS.
