Safety Recommendation History
From: NTSB
To: FAA
Date: 4/1/1988
Response: The FAA's last response to this recommendation on April 1, 1983, indicated that a review of autothrottle speed control systems would be conducted and the Board would be advised of any consequential changes in procedures. Since there has been no further response, the Safety Board concludes that no such actions have been taken and Safety Recommendation A-82-162 is being reclassified as "Closed--Unacceptable Action."

From: NTSB
To: FAA
Date: 12/14/1983
Response: We note that the FAA is continuing its review of this recommendation and that, because there are a number of different control laws used in the design of autothrottle speed control systems, it is a lengthy process. We will classify Safety Recommendation A-82-162 as "Open--Acceptable Action" awaiting notification of action resulting from the FAA's review.
