Safety Recommendation History
From: NTSB
To: FAA
Date: 12/4/2003
Response: On October 3, 2003, staff from the Federal Aviation Administration (FAA) and the National Transportation Safety Board met to discuss recommendations related to accident survivability issues, including Safety Recommendation A-96-149. At the meeting, the FAA indicated that it had requested the Society of Automotive Engineers (SAE) to develop an Aerospace Standard for aircraft crash axes. In 2001, the SAE published an Aerospace Information Report, with an associated Aerospace Standard and an Aerospace Recommended Practice. The FAA also reported that it had originally intended to issue an advisory circular promulgating the standard; however, the FAA's review of the wording in the applicable regulations indicated this was not permissible because the regulations only specified that a crash ax must be provided, not that the design or installation must be approved by the FAA. The Safety Board believes that, in view of the development of the Aerospace Information Report, Standard, and Recommended Practice, the FAA has met the intent of this recommendation in an acceptable alternate manner. Accordingly, Safety Recommendation A-96-149 is classified "Closed--Acceptable Alternate Action."

From: NTSB
To: FAA
Date: 8/29/2002
Response: Although preparation of AIR 5401, AS 5402, and ARP 5403 appears to be responsive to this recommendation, the Safety Board asks that the FAA supply a copy of these documents for review. Pending issuance of the AC, and the Safety Board's review of the SAE documents, Safety Recommendation A-96-149 remains classified "Open--Acceptable Response."

From: FAA
To: NTSB
Date: 6/17/2002
Response: Letter Mail Controlled 07/22/2002 10:54:58 AM MC# 2020705 Jane Garvey, Administrator, FAA, 6/17/02 In August 2001, the Society of Automotive Engineers published Aerospace Information Report 5401, Aircraft Crash Axes; Aerospace Standard 5402, Design and Performance Criteria, Aircraft Axes; and Aerospace Recommended Practice 5403, Aircraft Crash Axes. The FAA is processing an advisory circular (AC) to provide information to the aviation community for the design/selection of an aircraft crash ax and to assist the certification directorates in the approval process for these devices.

From: NTSB
To: FAA
Date: 12/23/1999
Response: PENDING A REVIEW OF THE AC, A-96-149 REMAINS CLASSIFIED "OPEN--ACCEPTABLE RESPONSE."

From: FAA
To: NTSB
Date: 10/1/1999
Response: Letter Mail Controlled 10/6/99 4:15:40 PM MC# 991109 THE FAA HAS ASKED THE SOCIETY OF AUTOMOTIVE ENGINEERS TO DEVELOP AN AEROSPACE STANDARD FOR AN AIRCRAFT CRASH AX. IT IS ANTICIPATED THAT THE AEROSPACE STANDARD WILL BE ISSUED BY MARCH 2000. THE FAA HAD INTENDED TO DRAFT AN ADVISORY CIRCULAR (AC) AS AN INTERIM ACTION TO PROVIDE INFORMATION TO THE AVIATION COMMUNITY FOR THE DESIGN/SELECTION OF AN AIRCRAFT CRASH AX AND TO ASSIST THE CERTIFICATION DIRECTORATES IN THE APPROVAL PROCESS FOR THESE DEVICES. HOWEVER, SINCE THE AEROSPACE STANDARD IS IN THE FINAL STAGES OF ISSUANCE, THE FAA HAS DECIDED TO PUBLISH THE AC IN ITS FINAL FORM ONCE THE AEROSPACE STANDARD IS ISSUED. I WILL PROVIDE THE BOARD WITH A COPY OF THE AEROSPACE STANDARD AND THE AC AS SOON AS THEY ARE ISSUED.

From: NTSB
To: FAA
Date: 11/10/1998
Response: A-96-149 ASKED THE FAA TO EVALUATE THE NECESSARY FUNCTIONS OF THE AIRCRAFT CRASH AX AND PROVIDE A TECHNICAL STANDARD ORDER OR OTHER SPECIFICATION FOR A DEVICE THAT SERVES THE FUNCTIONAL REQUIREMENTS OF SUCH TOOLS CARRIED ABOARD AIRCRAFT. PENDING THE BOARD'S REVIEW OF THE PUBLISHED AC AND THE COMPLETION OF THE SAE'S STANDARD, A-96-149 WILL REMAIN CLASSIFIED "OPEN--ACCEPTABLE RESPONSE."

Response: Letter Mail Controlled 8/11/98 5:12:13 PM MC# 980997 THE FAA HAS ASKED THE SOCIETY OF AUTOMOTIVE ENGINEERS TO DEVELOP AN AEROSPACE STANDARD FOR AN AIRCRAFT CRASH AX. IN THE INTERIM, THE FAA IS DRAFTING AN ADVISORY CIRCULAR TO PROVIDE INFO TO THE AVIATION COMMUNITY FOR THE DESIGN/SELECTION OF AN AIRCRAFT CRASH AX AND TO ASSIST THE CERTIFICATION DIRECTORATES IN THE APPROVAL PROCESS FOR THESE DEVICES. THE FAA WILL PROVIDE THE BOARD WITH COPY OF THE AC WHEN IT IS PUBLISHED.

To: FAA
Date: 5/1/1997
Response: THE A-96-149 ASKED THE FAA TO EVALUATE NECESSARY FUNCTIONS OF THE AIRCRAFT CRASH AX, AND PROVIDE TECHNICAL STANDARD ORDER OR OTHER SPECIFICATION FOR A DEVICE THAT SERVES THE FUNCTIONAL REQUIREMENTS OF SUCH TOOLS CARRIED ABOARD AIRCRAFT. BASED ON THE INFO GATHERED IN THIS REVIEW, THE FAA WILL TAKE APPROPRIATE ACTION TO INFORM THE AVIATION INDUSTRY. THE FAA ANTICIPATES THAT THE REVIEW WILL BE COMPLETED BY SEPTEMBER 1997. BASED ON THIS INFO, THE BOARD CLASSIFIES A-96-149 "OPEN--ACCEPTABLE RESPONSE."

From: FAA
To: NTSB
Date: 3/3/1997
Response: THE FAA IS REVIEWING THE POTENTIAL FUNCITONS OF AN AIRCRAFT CRASH AX. AS PART OF THIS REVIEW, THE FAA WILL CONTACT VARIOUS AIRCRAFT MANUFACTURERS TO DISCUSS THE SPECIFICATIONS THEY ARE CURRENTLY USING TO PURCHASE AXES. BASED ON THE INFO GATHERED IN THE REVIEW, THE FAA WILL TAKE APPROPRIATE ACTION TO INFORM THE AVIATION INDUSTRY. THE FAA ANTICIPATES THAT THE REVIEW WILL BE COMPLETED BY SEPTEMBER 1997.
