`ACTION: Notice of public meeting and
`request for comments.
`
`SUMMARY: The FAA is soliciting
`comments from the public, aircraft
`manufacturers and operators, and
`manufacturers of flight data recorders
`(FDR's) on the recent recommendations
`issued by the National Transportation
`Safety Board (NTSB) on increased FDR
`parameters. The FAA seeks comment on
`any aspect of the NTSB
`recommendations, including the
`potential safety benefits and financial
`costs for each of the NTSB

`and in analyzing specific exceptions or
`alternatives that should be considered.
`DATES: Comments must be received on
`or before March 31, 1995.
`A public meeting to discuss the NTSB
`recommendations will be held on April
`20, 1995, starting at 9 a.m.
`ADDRESSES: Comments on the NTSB
`recommendations discussed in this
`document should be mailed or
`delivered, in triplicate, to: Federal
`Aviation Administration, Attention:
`Rules Docket (AGC-200), 800
`Independence Ave., SW., Washington,
`DC 20591. Comments must be marked:

`
`SUPPLEMENTARY INFORMATION:
`Participation at the Meeting
`Requests from persons who wish to
`present oral statements at the public
`meeting should be received by the FAA
`no later than April 15, 1995. Such
`requests should be submitted to Jeanne
`Trapani at the address listed in the
`section entitled FOR FURTHER
`'INFORMATION CONTACT and should
`include a written summary of oral
`remarks to be presented. Requests
`received after the date specified above
`will be scheduled if time is available
`during the meeting; however, the name
`of those individuals may not appear on
`the written agenda for the public
`meeting.
`The FAA will prepare an agenda of
`speakers who will be available at the
`meeting. Every effort will be made to
`accommodate as many speakers as
`possible. The amount of time allocated
`to each speaker may be less than the
`amount of time requested.
`Background
`On February 22, 1995, the NTSB
`issued three recommendations to the
`FAA as a result of its investigation of
`accidents and incidents that, in the
`opinion of the NTSB, have
`demonstrated that more information
`about flight control parameters should
`be recorded by FDR's. A copy of the
`NTSB Safety Recommendation letter of
`February 22, 1995, has been placed in
`the FAA docket. Contrasting accident/
`incident data involving airplanes with
`5- and 128-parameter FDR's, the NTSB
`indicated that investigations were
`greatly aided by the availability of
`enhanced recorded information. The
`NTSB recommended that the FAA
`require operators to retrofit certain
`airplanes currently in operation with
`enhanced FDR's and require certain
`enhanced FDR's on newly-
`manufactured airplanes. The NTSB also
`issued recommendations to operators
`and manufacturers of aircraft operated
`under parts 121, 125, and 135. However,
`these recommendations will not be
`addressed at the public meeting. See
`attachment A of NTSB Safety
`Recommendation letter dated February
`22, 1995.
`The NTSB stated that among the
`additional flight control parameters that
`are needed are parameters that pertain
`to the flight control inputs and control
`surface positions. Acknowledging that
`
`the cost of increasing the recorded
`parameters on FDR's would necessitate
`a significant monetary investment, the
`NTSB stated that public safety
`outweighs the costs.
`With this notice, the FAA is soliciting
`comments on the following NTSB
`recommendatipns:
`Require that each Boeing 737 airplane
`operated under 14 CFR parts 121 or 125 be
`equipped, by December 31, 1995, with a
`flight data recorder system that records, as a
`minimum, the parameters required by
`'current regulations applicable to that
`airplane plus the following parameters
`(recorded at the sampling rates specified in
`"Proposed Minimum FDR Parameter
`Requirements for Airplanes in Service" [see
`Table 1 below]: lateral acceleration; flight
`control inputs for pitch, roll, and yaw; and
`primary flight control surface positions for
`pitch, roll, and yaw.
`Amend, by December 31, 1995, 14 CFR
`121.343, 125.225, and 135.152 to require that
`Boeing 727 airplanes, Lockheed L-1011
`airplanes, and all transport category airplanes
`operated under 14 CFR parts 121, 125, or 135
`whose type certificate applies to airplanes
`still in production, be equipped to record on
`a flight data recorder system, as a minimum,
`the parameters listed in "Proposed Minimum
`FDR Parameter Requirements for Airplanes
`in Service" plus any other parameters
`required by current regulations applicable to
`each individual airplane. Specify that the
`airplanes be so equipped by January 1, 1998,
`or by the later date when they meet Stage 3
`noise requirements but, regardless of Stage 3
`compliance status, no later than December
`31, 1999.
`Amend, by December.31, 1995, 14 CFR
`121.343, 125.225, and 135.152 to require that
`all airplanes operated under 14 CFR parts
`121, 125, or 135 (10 seats or larger), for which
`an original airworthiness certificate is
`received after December 31, 1996, record the
`parameters listed in "Proposed FDR
`Enhancements for Newly Manufactured
`Airplanes" [see Table 2 belowl on a flight
`data recorder having at least 25-hour
`recording capacity.
`The FAA requests that commenters be
`specific and provide as much factual
`detail in comments as possible. Cost
`information is also particularly
`requgsted.
`Because of the time frame
`recommended by the NTSB and the date
`of the public meeting, the FAA requests
`that commenters be timely in their
`response. All comments received will be
`available, both before and after the
`closing date for comments, in the Rules
`Docket.
`The FAA anticipates that comments
`provided in response to this notice will
`assist the agency in responding to the
`NTSB recommendations.
`Meeting Procedures
`The following procedures are
`established to facilitate the meeting:

`
`(1) There will be no admission fee or
`other charge to attend or to participate
`in the meeting. The opportunity to
`speak will be available to all persons
`who have requested in advance to
`present statements or who register on
`the day of the meeting subject to
`availability of space in the meeting
`room.
`(2) There will be morning, lunch, and
`afternoon breaks.
`(3) The meeting may adjourn early if
`scheduled speakers complete their
`statements in less time than is
`scheduled for the rheeting.
`(4) An individual, whether speaking
`in a personal or a.representative
`capacity on behalf of an organization,
`may be limited to a 10-minute
`statement. If possible; we will notify the
`speaker if additional time is available.
`(5) The FAA will try to a'ccommodate
`all speakers. If the available time does
`not permit this, speakers generally will
`be scheduled on a first-come-first-served
`basis. However, the FAA reserves the
`right to exclude some speakers if
`necessary to present a balance of
`viewpoints and issues.
`(6) Sign and oral interpretation may
`be made available at the meeting, as
`well as an assistive listening' device, if
`requested at least 10 calendar days
`before the meeting.
`(7) Representatives of the FAA will
`preside over the meeting. A panel of
`FAA personnel involved in this issue
`will be present.
`(8) The meetingwill be recorded by
`a court reporter. A transcript of-the
`meeting and any material accepted by
`the panel during the meeting will be
`included in the public docket. Any
`person who is interested in purchasing
`a copy of the transcript should contact
`the court reporter directly.
`(9) The FAA will review and consider
`all matbrial presented by participants at
`the meeting. Position papers or material
`presenting views or information related
`to the FDR's may be accepted at the
`discretion of the presiding officer and
`subsequently placed in the public
`docket. The FAA requests that persons
`participating in the meeting provide 10
`copies of all materials to be presented
`for distribution to the panel members;
`other copies may be provided to the
`audience at the discretion of the
`participant.
`(10) Statements made by members of
`the meeting panel are intended to
`facilitate discussion of the-issues or to
`clarify issues. Any statement made
`during the meeting by a member of the
`panel is not intended to be, and should
`not be construed as, a position of the
`FAA.
`
`(11) The meeting is designed to solicit
`public views and more complete
`information. Therefore, the meeting will
`be conducted in an informal and
`nonadversarial manner. No individual
`will be subject to cross-examination by
`any other participant; however, panel
`members may ask questions to clarify a
`statement and to ensure a complete and
`-accurate record.
`(12) Speakers are encouraged, before
`the meeting, to review the comments
`received in the docket, providing them
`an opportunity to express their view at
`the meeting on the comments in the
`docket, as well as present any additional
`comments.
