Safety Recommendation History
From: NTSB
To: FAA
Date: 3/6/1995
Response: THE BOARD NOTES THAT 14 CFR PART 23, AMENDMENT 23-43, ISSUED 3/29/93, RESULTED IN SIGNIFICANT CHANGE TO THE ICE PROTECTION REQUIREMENTS OF 14 CFR 23.1419. HOWEVER, REGARDING THE ISSUE OF REQUIRING TWO ICE OBSERVATION LIGHTS, THE BOARD NOTES THAT THE WORDING IN THE AMENDMENT, "EXTERNAL LIGHTING MUST BE PROVIDED THAT IS ADEQUATE TO ENABLE THE MONITORING TO BE DONE AT NIGHT," IS IDENTICAL TO THE WORDING ORIGINALLY IN 14 CFR 23.1419. BECAUSE THE FAA HAS NOT ADDRESSED THE RECOMMENDATION TO REQUIRE AIRPLANES CERTIFIED FOR TWO-PILOT OPERATION TO BE CONFIGURED WITH TWO ICE OBSERVATION LIGHTS, THE BOARD CLASSIFIES A-94-117 "CLOSED--UNACCEPTABLE ACTION.

From: FAA
To: NTSB
Date: 8/29/1994
Response: THE FAA HAS REVIEWED THE ISSUED OF DETECTION OF AIRFRAME ICE ACCUMULATION ALONG WITH INFO DEVELOPED BY THE BOARD DURING PREVIOUS ACCIDENT INVESTIGATIONS. THE FAA AGREEES 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.
