Safety Recommendation History
From: NTSB
To: FAA
Date: 3/6/1995
Response: THE BOARD NOTES THAT THE FAA IS AWARE THAT JETSTREAM AIRCRAFT LIMITED HAS A CUSTOMER OPTION MODIFICATION TO INSTALL A RIGHT WING ICE LIGHT ON THE MODEL 3100 AT THE TIME OF MANUFACTURE. THE FAA ALSO NOTES THAT JETSTREAM IS DEVELOPING A SERVICE BULLETIN (SB) TO INSTALL A RIGHT WING LIGHT ON IN-SERVICE AIRPLANES AS AN OPTION. THE FAA STATES THAT IT WILL REVIEW THE SB & INFORM OPERATORS WHEN THE INFO IS AVAILABLE. HOWEVER, A MANFACTURER'S SB DOES NOT REQUIRE AN OPERATOR TO PERFORM THE MODIFICATION &, AS YOU KNOW, ONLY AN AD WOULD ESTABLISH A REQUIREMENT FOR SUCH A MODIFICATION. THERE IS LITTLE REASON TO EXPECT THAT OPERATORS WHO CHOSE NOT TO HAVE THE LIGHT INSTALLED AT THE TIME OF MANUFACTURE WOULD NOW ELECT TO ADD THE LIGHT AS AN OPTIONAL SB MODIFICATON. THEREFORE, THE BOARD CLASSIFIES A-94-116 "CLOSED--UNACCEPTABLE RESPONSE."

From: FAA
To: NTSB
Date: 8/29/1994
Response: THE FAA HAS REVIEWED THE ISSUE OF DETECTION OF AIRFRAME ICE ACCUMULATION ALONG WITH INFO DEVELOPED BY THE BOARD DURING PREVIOUS ACCIDENT INVESTIGATION. THE FAA AGREES THAT A BETTER REQUIREMENT FOR THE DETECTION OF ICE FORMATION IS NEEDED & HAS TAKEN APPROPRIATE ACTION TO ADDRESS THIS ISSUE. HOWEVER, THE FAA DOES NOT BELIEVE THAT IT IS NECESSARY TO ISSUE AN AIRWORTHINESS DIRECTIVE AS REQUESTED BY A-94-116 TO REQUIRE THE INSTALLATION OF A SECOND WING ICE OBSERVATION LIGHT. WHILE THIS IS ONE OPTION, 14 CFR PART 23, AMENDMENT 23-43, ISSUED 3/29/93, ADDRESSES THE INTENT OF THIS RECOMMENDATION WITH MORE LATITUDE TO THE MANUFACTURER & OPERATORS.
