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 recommendations:

    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 below] 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 requested.
    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: [[Page 13863]] 
    (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 meeting.
    (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 accommodate 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 meeting will 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 material 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.
