Safety Recommendation History
From: NTSB
To: FAA
Date: 6/20/1988
Response: The Safety Board is pleased to learn that on April 19, 1988, the FAA issued an airworthiness directive (Docket No. 87-NM-141-AD; Amendment 39-5903) to require inspection of the control column base for cracks on Lockheed Model 382 series airplanes. We appreciate the action taken to satisfy this recommendation which is now classified as "Closed--Acceptable Action."

From: FAA
To: NTSB
Date: 5/12/1988
Response: ON APRIL 19, 1988, THE FAA ISSUED AN AIRWORTHINESS DIRECTIVE (DOCKET NO. 87-NM-141-AD; AMENDMENT 39-5903) TO REQUIRE INSPECTION OF THE CONTROL COLUMN BASE FOR CRACKS ON LOCKHEED MODEL 382 SERIES AIRPLANES.

From: NTSB
To: FAA
Date: 10/2/1987
Response: The Safety Board is pleased to learn that the FAA plans to develop a Notice of Proposed Rulemaking (NPRM) which will address the inspection of components of the elevator control system for damage. Pending the Board's review of the proposed NPRM and the final action taken on this issue, Safety Recommendation A-87-30 has been classified as "Open--Acceptable Action."

From: FAA
To: NTSB
Date: 8/12/1987
Response: THE FAA AGREES WITH THE INTENT OF THIS RECOMMENDATION, BUT BELIEVES THAT THE APPROPRIATE RESPONSE IS MORE EXTENSIVE THAN A ONE-TIME INSPECTION OF THE BASE OF THE CONTROL COLUMN. THE FAA EVALUATION INDICATES THAT SEVERAL ADDITIONAL FACTORS NEED TO BE CONSIDERED. THERE ARE OTHER COMPONENTS OF THE ELEVATOR CONTROL SYSTEM THAT HAVE LOWER STRENGTH MARGINS THAT THE CONTROL COLUMN BASE. THE FAA PLANS TO PROPOSE THAT THESE COMPONENTS ALSO BE INSPECTED. THE AIRPLANE MANUFACTURER IS CURRENTLY DEVELOPING THE APPROPRIATE INSPECTION METHODS AND PROCEDURES. ONCE THE FAA HAS APPROVED THESE METHODS AND PROCEDURES, IT WILL ISSUE A NPRM TO MAKE COMPLIANCE WITH THESE METHODS AND PROCEDURES MANDATORY.
