Safety Recommendation History
From: NTSB
To: FAA
Date: 6/4/1987
Response: The Safety Board finds that the FAA's review of the Supplemental Type Certificate (STC) SA 1596 CE and the subsequent amendment of this STC on July 23, 1982, to correct problems found during the review complies with the intent of this recommendation. Safety Recommendation A-81-92 has been classified as "Closed-- Acceptable Action."

From: FAA
To: NTSB
Date: 5/7/1987
Response: THE FAA ISSUED AN AMENDED STC SA 1596 CE ON JULY 23, 1982, TO REFLECT THE RESULTS OF THE TYPE INSPECTION AUTHORIZATION TESTS AND INSPECTIONS. OUR RECORDS INDICATE THAT THE BOARD DID NOT RECEIVE A COPY OF THE AMENDED SUPPLEMENTAL TYPE CERTIFICATION AT THE TIME IT WAS ISSUED. ALL AIRPLANES WHICH INCORPORATED STC 1596 CE HAVE BEEN MODIFIED TO THE LATEST REVISION.

From: FAA
To: NTSB
Date: 12/10/1986
Response: THE FAA'S RESPONSE OF MAY 12, 1982 INDICATED THAT THEY HAD REVIEWED THE SUBJECT STC AND THE EFFECTS OF THE INSTALLATION IN LOCKHEED JET STAR MODEL 1329 AIRPLANES AND HAD DETERMINED THAT THE INSTALLATION INSTRUCTIONS WERE NOT SUFFICIENTLY CLEAR CAUSING WIRING ERRORS. WE WERE ALSO INFORMED THAT THE FAA HAS ISSUED AN AMENDED TYPE INSPECTION AUTHORIZATION TO EVALUATE ELECTRICAL SYSTEM TESTS UNDER VARIABLE LOADS, NOISE ASSESSMENT OF THE ELECTRICAL SYSTEM, AND VERTIFICATION OF ELECTRICAL PORTIONS OF THE AIRPLANE FLIGHT MANUAL AND SUPPLEMENTALS. THE STC HOLDER WAS EXPECTED TO COMPLETE THE TESTS INSPECTIONS BY MID-MAY 1982 AND, FOLLOWING SUCCESSFUL EFFORTS, THE SUPPLEMENTAL TYPE CERTIFICATE WOULD BE AMENDED. THE FAA WOULD KEEP THE BOARD ADVISED OF THE PROGRESS RELA TIVE TO THIS RECOMMENDATION.

From: NTSB
To: FAA
Date: 12/10/1986
Response: The FAA's response of May 12, 1982, indicated that it had reviewed the Supplemental Type Certificate (STC) and the effects of the installation in Lockheed JetStar Model 1329 airplanes and had determined that the installation instructions were not sufficiently clear, causing wiring errors. We were further informed that the FAA had issued an amended Type Inspection Authorization to evaluate the electrical system and that the STC would be amended. In our followup letter of November 2, 1982, we thanked the FAA for its offer to keep us advised of the progress of this recommendation which we classified as "Open-- Acceptable Action." However, we have not received any further correspondence. The Safety Board would appreciate being informed of any progress to implement Safety Recommendation A-81-92, which remains in an "Open--Acceptable Action" status.
