Safety Recommendation History
From: NTSB
To: FAA
Date: 2/8/1999
Response: THE SAFETY BOARD IS DISPLEASED THAT ALTHOUGH THE FAA AGREES ON THE IMPORTANCE OF THESE RECOMMENDATIONS, MORE THAN 10 YEARS HAVE PASSED SINCE THEY WERE ISSUED, AND THE FAA HAS YET TO FULLY ACCOMPLISH EITHER. THE BOARD IS PARTICULARLY DISAPPOINTED WITH THE FAA'S RESPONSE TO A-88-158, ISSUED 10 YEARS AGO, WHICH ASKED FOR THE EXPEDITIOON OF RULEMAKING. BECAUSE OF THE LENGTH OF TIME THAT HAS ALREADY PASSED AND THE CURRENT LACK OF REGULATIONS THAT FULLY ADDRESS THESE ISSUES, A-88-96 AND A-88-158 ARE CLASSIFIED "CLOSED--UNACCEPTABLE ACTION."

From: FAA
To: NTSB
Date: 5/6/1998
Response: Letter Mail Controlled 5/11/98 3:31:24 PM MC# 980605 IN JUNE 1993, THE FAA ISSUED NOTICE 93-71, "OCCUPANT PROTECTION STANDARDS FOR COMMUTER CATEGORY AIRPLANES." THIS NOTICE PROPOSED 14 CFR PART 23 COMMUTER AIRWORTHINESS STANDARDS FOR NORMAL, UTILITY, ACROBATIC, AND COMMUTER CATEGORY AIRPLANES BY UPGRADING THE REQUIREMENT FOR BOTH SEAT/RESTRAINT SYSTEMS AND FOR FLAMMABILITY STANDARDS FOR SEAT CUSHIONS. THE FAA HAD ANTICIPATED THE ISSUANCE OF THE FINAL RULE IN MID-1996. HOWEVER, THE ADOPTION OF THE FINAL COMMUTER RULE ON 1/19/96, BROUGHT SCHEDULED PASSENGER OPERATIONS IN AIRPLANES OF 10 OR MORE PASSENGER SEATS UNDER THE REQUIREMENTS OF 14 CFR PART 121. ALTHOUGH THE COMMUTER RULE DOES ADDRESS A PORTION OF THESE RECOMMENDATIONS, IT ALSO CHANGED SOME OF THE REQUIREMENTS FOR THE ISSUANCE OF NOTICE 93-71 AND DELAYED THE PROJECTED ADOPTION DATE. SPECIFICALLY, THE COMMUTER RULE DID NOT ADDRESS THE FOLLOWING AIRPLANES: NEWLY TYPE CERTIFICATED COMMUTER-CATEGORY AIRPLANES THAT ARE INTENDED FOR 14 CFR PART 135 SCHEDULED PASSENGER SERVICE WITH FEWER THAN 10 SEATS; 14 CFR PART 135 UNSCHEDULED PASSENGER SERVICE WITH 19 SEATS OR FEWER; AND AIRCRAFT USED FOR GENERAL AVIATION PURPOSES. ORIGINALLY, NOTICE 93-71 WAS INTENDED TO MEET THE INTENT OF A-88-158 BY PROPOSING DYNAMIC SEAT TESTING STANDARDS AND FLAMMABILITY STANDARDS FOR SEAT CUSHIONS FOR NEWLY TYPE CERTIFICATED COMMUTER-CATEGORY AIRPLANES. AS A RESULT OF ADOPTING THE COMMUTER RULE, A COST-BENEFIT ANALYSIS IS NOW NECESSARY TO CONSIDER THE BENEFITS OF NOTICE 93-71 FOR NEWLY TYPE CERTIFICATED COMMUTER-CATEGORY AIRPLANES INTENDED FOR THOSE AIRPLANES THAT THE COMMUTER RULE DID NOT ADDRESS. THE COMMUTER RULE HAS ALSO AFFECTED THE FAA'S PLAN TO PROPOSE ADDITIONAL RULEMAKING TO REQUIRE FIREBLOCKING OF SEATS ON ALL EXISTING AIRPLANES CERTIFICATED UNDER SPECIAL FEDERAL AVIATION REGULATION (SFAR) 23, SFAR 41, OR 14 CFR PART 23 AND OPERATING IN ACCORDANCE WITH 14 CFR PART 135. SINCE ALL SCHEDULED SERVICE INVOLVING AIRPLANES CARRYING 10 PASSENGERS OR MORE HAS NOW BEEN MOVED TO 14 CFR PART 121, THE PROJECTED COST-BENEFIT ANALYSIS HAS ALSO BEEN AFFECTED. THE FAA PLANS TO WITHDRAW NOTICE 93-71 AND TASK THE AVIATION RULEMAKING ADVISORY COMMITTEE TO DEVELOP RECOMMENDATIONS FOR DYNAMIC SEAT TEST REQUIREMENTS FOR COMMUTER-CATEGORY AIRPLANES OPERATED UNDER 14 CFR PART 23 AND SMALL TRANSPORT-CATEGORY AIRPLANES OPERATED UNDER 14 CFR PART 25. IN A SEPARATE ACTION, THE FAA INTENDS TO INITIATE A NEW RULEMAKING PROPOSAL ON FIREBLOCKING REQUIREMENTS FOR NEWLY TYPE CERTIFICATED COMMUTER-CATEGORY AIRPLANES.

From: NTSB
To: FAA
Date: 9/17/1996
Response: THE BOARD NOTES THAT THE FAA ISSUED A FINAL RULE TO AMEND 14 CFR PART 135 TO BE CONSISTENT WITH 14 CFR PART 121 WHICH DOES, IN PART, MEET THE INTENT OF THESE RECOMMENDATIONS. HOWEVER, THE BOARD BELIEVES THAT THE ISSUANCE OF ANOTHER FINAL RULE ENTITLE "OCCUPANT PROTECTION STANDARDS FOR COMMUTER CATEGORY AIRPLANES" & THE SUBSEQUENT ADDITIONAL RULEMAKING PROPOSING TO REQUIRE FIREBLOCKING OF SEATS ON ALL EXISTING AIRPLANES HAVING SFAR 23, & SFAR 41, OR COMMUTER CATEGORY AS THEIR CERTIFICATION BASIS WILL FULLY MEET THE INTENT OF THESE RECOMMENDATIONS. PENDING THAT RULEMAKING ACTION, THE BOARD CLASSIFIES A-88-96 & A-88-158 "OPEN--ACCEPTABLE RESPONSE."

From: FAA
To: NTSB
Date: 2/16/1996
Response: THE FAA ISSUED ITS FINAL RULE TO AMEND 14 CFR PART 135 TO BE CONSISTENT WITH 14 CFR PART 121. THIS FINAL RULE REQUIRES, IN PART THAT NEW TYPE-CERTIFICATED AIRPLANES THAT CARRY 10 OR MORE PASSENGERS IN SCHEDULED PASSENGER SERVICE MEET THE REQUIREMENTS OF 14 CFR PART 25. WITH THE ISSUANCE OF THIS RULE, THE FAA CAN PROCEED WITH ISSUING THE FINAL RULE ENTITLED OCCUPANT PROTECTION STANDARDS FOR COMMUTER CATEGORY AIRPLANES. THIS REGULATORY DOCUMENT WILL UPGRADE THE REQUIREMENTS FOR BOTH SEAT/RESTRAINT SYSTEMS & FOR FLAMMABILITY STANDARDS FOR SEAT CUSHIONS ON ALL NEWLY CERTIFICATED COMMUTER CATEGORY AIRPLANES NOT COVERED BY THE NEW 14 CFR PART 121 RULE. THE FAA ANTICIPATES ISSUANCE OF THIS FINAL RULE BY JULY 1996. AFTER THE RULE TO ADDRESS OCCUPANT PROTECTION STANDARDS FOR COMMUTER CATEGORY AIRPLANES ISSUED, THE FAA WILL PROPOSE ADDITIONAL RULEMAKING PROPOSING TO REQUIRE FIREBLOCKING OF SEATS ON ALL EXISTING AIRPLANES HAVING SPECIAL FEDERAL AVIATION REGULATIONS (SFAR 41 ) REGARDLESS OF WHETHER THEY ARE IN SCHEDULE OR NONSCHEDULED SERVICE. IT IS ANTICIPATED THAT THIS NOTICE OF PROPOSED RULEMAKING WILL BE ISSUED IN JANUARY 1997.

From: NTSB
To: FAA
Date: 8/30/1995
Response: THE BOARD IS PLEASED THAT THE FAA HAS ISSUED NOTICES OF PROPOSED RULEMAKING THAT ADDRESS BOTH RECOMMENDATIONS PENDING ADOPTION OF PROPOSED RULE CHANGES, THE BOARD CLASSIFIES A-88-96 & -158 "OPEN--ACCEPTABLE RESPONSE."

From: FAA
To: NTSB
Date: 3/10/1995
Response: FAA ISSUED A NPRM ON 6/24/93, PROPOSING TO AMEND 14 CFR PART 23 COMMUTER AIRWORTHINESS STANDARDS FOR NORMAL, UTILITY, ACROBATIC, & COMMUTER CATEGORY AIRPLANES BY UPGRADING THE REQUIREMENTS FOR BOTH SEAT/RESTRAINT SYSTEMS & FOR FLAMMABILITY STANDARDS FOR SEAT CUSHIONS. THE COMMENT PERIOD ENDED 11/12/93. HOWEVER, DUE TO EXTENSIVE COMMENTS RECEIVED IN RESPONSE TO NPRM, THE FAA REOPENED THE COMMENT PERIOD TO 3/4/95. THIS NPRM ADDRESSES THE INTENT OF A-88-158.

From: NTSB
To: FAA
Date: 5/26/1994
Response: THE BOARD NOTES THAT ON JUNE 24, 1993, THE FAA ISSUED A NOTICE OF PROPOSED RULEMAKING (NPRM 93-71) THAT PROPOSED TO AMEND THE AIRWORTHINESS STANDARDS FOR NORMAL, UTILITY, ACROBATIC, & COMMUTER CATEGORY AIRPLANES. THE PROPOSED RULES WOULD, AMONG OTHER THINGS, UPGRADE THE REQUIREMENTS FOR BOTH SEAT/RESTRAINT SYSTEMS & FOR FLAMMABILITY STANDARDS FOR SEAT CUSHIONS USED IN COMMUTER CATEGORY AIRPLANES. THE BOARD COMMENTED ON THE NPRM & ENDORSED THE PROPOSED STANDARDS AS THEY APPLIED TO COMMUTER CATEGORY AIRPLANES. PENDING REVIEW OF THE FINAL STANDARDS, THE BOARD CLASSIFIES A-88-158 "OPEN-ACCEPTABLE RESPONSE."

From: FAA
To: NTSB
Date: 4/25/1994
Response: THE FAA AGREES WITH THIS RECOMMENDATION & ON JUNE 24, 1993, ISSUED A NOTICE OF PROPOSED RULEMAKING (NPRM) PROPOSING TO AMEND THE AIRWORTHINESS STANDARDS FOR NORMAL, UTILITY, ACROBATIC, & COMMUTER CATEGORY AIRPLANES BY UPGRADING THE REQUIREMENTS BOTH SEAT/RESTRAINT SYSTEMS & FOR FLAMMABILITY STANDARDS FOR SEAT CUSHIONS USED IN COMMUTER CATEGORY AIRPLANES. I WILL PROVIDE THE BOARD WITH A COPY OF THE FINAL DOCUMENT AS SOON AS IT IS ISSUED.

From: NTSB
To: FAA
Date: 10/10/1989
Response: We note that the FAA's Civil Aeromedical Institute has conducted a limited test program of a modified commuter seat and that the results of the test have been evaluated and a joint meeting held between the General Aviation Manufacturers Association and the FAA to discuss the results. We also note that the FAA is considering a notice of proposed rulemaking (NPRM) to require dynamic testing of seat/restraint systems for commuter category airplanes. We will be pleased to respond to an NPRM. This safety Recommendation is classified as "Open--Acceptable Action."

From: FAA
To: NTSB
Date: 9/21/1989
Response: THE FAA'S CAMI CONDUCTED A LIMITED TEST PROGRAM OF A MODIFIED COMMUTER SEAT. THE RESULTS OF THE TEST HAVE BEEN EVALUATED AND A JOINT MEETING WAS HELD BETWEEN GAMA AND THE FAA TO DISCUSS THESE RESULTS. THE FAA IS NOW CONSIDERING THE ISSUANCE OF A NPRM PROPOSING TO REQUIRE DYNAMIC TESTING OF SEAT/RESTRAINT SYSTEMS FOR COMMUTER CATEGORY AIRPLANES. I WILL PROVIDE THE BOARD WITH A COPY OF ANY DOCUMENT THAT MAY BE ISSUED.

From: NTSB
To: FAA
Date: 4/19/1989
Response: We are pleased to learn that the FAA is considering the issuance of a notice of proposed rulemaking to require dynamic testing of seat/restraint systems for commuter category airplanes. The calculations and formula used to determine the vertical accelerations (19.8 to 35.7 G's) and the horizontal accelerations requested in your letter have been provided to the FAA through staff channels. Pending the FAA's further response, this recommendation is classified as "Open--Acceptable Action."

Response: THE FAA IS CONSIDERING THE ISSUANCE OF A NPRM TO REQUIRE DYNAMIC TESTING OF SEAT/RESTRAINT SYSTEMS FOR COMMUTER CATEGORY AIRPLANES. I AM REQUESTING THAT THE SAFETY BOARD PROVIDE THE FAA WITH A COPY OF THE CALCULATIONS AND FORMULA USED TO DETERMINE THE VERTICAL ACCELERATIONS (19.8 TO 35.7 G'S) AND THE HORIZONTAL ACCELERATIONS FOR THIS ACCIDENT. THIS INFORMATION WOULD ASSIST THE FAA IN DETERMINING THE ACCELERATION AND VELOCITY REQUIREMENT FOR TESTING OF SEAT/RESTRAINT SYSTEMS FOR COMMUTER CATEGORY AIRPLANES..."
