Aviation Data Modernization

AGENCY: Office of the Secretary, Department of Transportation.

ACTION: Notice of withdrawal of proposed rulemaking.

-----------------------------------------------------------------------

SUMMARY: The Department of Transportation (the Department) is 
withdrawing a Notice of Proposed Rulemaking (NPRM) issued on February 
17, 2005 (70 FR 8140 et seq.) that proposed revisions to the rules 
governing the nature, scope, source of and means for collecting and 
processing aviation traffic data.
    We are withdrawing this NPRM because, after review of all comments, 
we have determined that the approach we proposed to solve the 
identified problems does not adequately address a number of aspects, 
including measures that could both enhance the utility, integrity and 
accuracy of the data and reduce the cost of reporting. This action is 
being taken to allow for later revision and refinement of a proposed 
methodology for aviation data modernization.

DATES: June 1, 2011.

FOR FURTHER INFORMATION CONTACT: Richard Pittaway, Office of Aviation 
Analysis, 1200 New Jersey Ave., SE., Room W86-461, Washington, DC 
20590, (202) 366-8856.

SUPPLEMENTARY INFORMATION: 

Background

    On July 15, 1998, the Department published an Advance Notice of 
Proposed Rulemaking (ANPRM) (63 FR 28128) requesting comment on a 
variety of issues related to aviation economic data collection. The 
ANPRM noted that the Origin-Destination Survey of Airline Passenger 
Traffic (O&D Survey) and Form 41, Schedule T-100--U.S. Air Carrier 
Traffic and Capacity Data by Nonstop Segment and On-flight Market and 
Form 41, and Schedule T-100(f)--Foreign Air Carrier Traffic and 
Capacity Data by Nonstop Segment and On-flight Market (the last two are 
known collectively as the T-100/T-100(f))O&D Survey and the T-100/T-
100(f)) may not provide sufficiently reliable data in some 
circumstances to ensure that the Department can meet its obligation to 
disseminate information that enables the transportation system to adapt 
to the present and future needs of the American public. At that time, 
we stated our concern that the aviation data systems should be reviewed 
and modernized in order to meet our statutory responsibilities.
    Also, because of difficulties private industry would have in 
assembling these data, the need for scheduled air traffic information 
cannot be satisfied other than through governmental means. However, 
while there are no other sources of comprehensive traffic data 
available in the aviation industry, a significant market exists in 
supplying services to supplement the Department's information offerings 
using the service provider's own statistical insight and experience. 
The public, academics, manufacturers, airports, air carriers, local, 
state and various branches of the Federal government all remain 
dependent on the reliability of this commercially enhanced data.
    Approximately 50 comments were filed in response to the ANPRM by 
airlines, airports, trade associations, unions, and private citizens 
who use this data. Commenters confirmed that these data are not only 
critical to the work of both private and public aviation stakeholders 
(including the reporting airlines themselves), but that there are 
universal concerns about the capability and accuracy of the existing 
data collection to satisfy the changing needs of the industry and its 
stakeholders. The respondents overwhelmingly agreed

[[Page 31512]]

that the O&D Survey and the T100 segment data were essential. 
Commenters repeatedly mentioned that the current data elements 
collected were insufficient to meet the data needs of the public and 
the aviation industry now and in the future. There was near universal 
agreement that the data suffer from lack of quality and lack of 
consistency. Deficiencies in the O&D Survey and in the T-100/T-100(f) 
further reduce the ability of the data to meet the needs of the 
aviation community.
    On February 17, 2005, OST published a notice of proposed rulemaking 
(NPRM) (70 FR 8140 et seq.) as part of the Department's effort to 
revise the requirements for aviation data to modernize the way we 
collect, process, and disseminate aviation data. The NPRM reflected 
analysis of the O&D Survey and T-100/T-100(f) data, and it documented 
the use of that data by the government, the airline industry, 
consumers, and other stakeholders. We proposed revisions to the rules 
governing the nature, scope, source of and means for collecting and 
processing this aviation traffic data.
    At the time the notice was published, we noted that the Department 
has a statutory responsibility to collect and disseminate information 
about aviation transportation in the U.S. The Department must, at 
minimum, collect information on the origin and destination of 
passengers and information on the number of passengers traveling by air 
between any two points in air transportation, 49 U.S.C. sec. 329(b). 
Additionally, the Department is charged with maintaining a sound 
regulatory system that is responsive to the needs of the public, and 
must disseminate information to make it easier to adapt the air 
transportation system to the present and future needs of the commerce 
of the United States (49 U.S.C. 40101(a) (7)).
    We also acknowledged the Department's responsibility to maximize 
the quality, objectivity, utility, and integrity of influential 
statistical information it disseminates. Although the O&D Survey 
collected quarterly and the T-100/T-100(f) collected monthly are the 
means by which the Department disseminates aviation traffic 
information, the NPRM identified various technical deficiencies and 
limitations in the data.
    In the 2005 NPRM, we also proposed a plan to create the O&D Survey 
using a fundamentally different collection methodology and considered 
commensurate changes in the collection of the T-100/T-100(f). In 
addition to seeking comments on the change of methodology, we sought 
input into other key topics such as information about what kind of data 
should be withheld from release for reasons of competitive sensitivity.

Discussion of Comments

    In response to the 2005 NPRM, the Department received substantive 
comments from ten organizations or groups, and limited comments from 
twelve additional groups or organizations. Most of the commenters were 
airlines or aviation trade associations, but some of the other users of 
the data also provided comments. While there was opposition to certain 
aspects of the Department's proposed methodology for collecting data, 
no comments filed in response to the NPRM disputed the Department's 
authority to gather aviation information, the Department's review of 
the data's current deficiencies, the Department's assessment of the 
data's limitations, or the Department's assertion that the current 
traffic statistics had outlived the economic model for which it was 
designed. We, therefore, conclude that there is support for obtaining 
and disseminating accurate aviation traffic data by aligning it with 
modern airline business practices, but that the methodology we proposed 
may not have been the best solution to repair the deficiencies in the 
system.
    The Department's proposal for collecting aviation traffic data 
continued to rely on the airline passenger revenue accounting system as 
the principal source of data. However, we proposed changing the carrier 
designated to report the data, increasing the scope and volume of data 
collected, and reducing the number of reporting exemptions. The NPRM 
also sought comments on several specific issues to achieve greater 
uniformity in statistical reporting in light of the industry's 
divergent business models. We believed that changing the carrier 
responsible for reporting a ticket to the ticket issuing carrier would 
be a significant simplification in the airline's process of reporting 
and would, therefore, result in a reduction of reporting costs. While 
there was considerable support for these changes, the comments 
indicated that some believed that the burdens of reporting the data 
would still be disproportionately high.
    We proposed a specific set of data elements that we anticipated 
would be necessary in the new methodology to define one-way trips, and 
asked for comment on how to construct the one-way trips. However, no 
one-way trip methodology appeared in the record, leading a number of 
commenters to claim that the Department had not sufficiently 
articulated a rationale for collecting the newly proposed data 
elements.
    Similarly, the Department proposed that the public supply guidance 
regarding how the Department should safeguard competitively sensitive 
information, but no such safeguards were suggested in the comments. 
With no specific proposals for safeguards in the record, a number of 
commenters asserted that the Department had not made sufficient plans 
to safeguard competitively sensitive information.
    In addition, the Department pointed to evidence that the current 
ticket sample methodology produces a sample that could be impacted by 
decisions at travel agencies to assign ticket numbers at their own 
convenience for their own reasons. We have no authority to regulate 
such activities of travel agents, and so the Department proposed to 
either change the method of creating the sample or to do away with 
sampling and collect a census of data. Despite evidence presented in 
the NPRM that the current 10% sampling system produces a biased sample 
of inconsistent size and inadequate scope, and the Department's 
calculation indicating that to ensure reasonable accuracy the target 
sample size should be a minimum of 24.34% of the total enplaned 
passengers, several airlines commented that a 20% sample with no change 
in collection methodology would be easier to implement and therefore 
preferable to the Department's proposal.
    Although many stakeholders provided comments on the manner in which 
data could be collected, it is the airlines who must supply the data 
and are, therefore, in the best position to effectively comment on the 
difficulty of producing the data. Some airlines questioned certain 
aspects of the rulemaking's data collection proposal, characterizing 
the changes as potentially expensive and cumbersome. No airline, 
however, suggested an alternative, statistically defensible proposal 
for collection of data that would be less expensive and less cumbersome 
while simultaneously producing the desired improvements in the utility 
of the data.

Reason for Withdrawal

    The stated purposes of this rulemaking were to (1) Reduce the long-
term reporting burden on the Participating Carriers, (2) make the O&D 
Survey more relevant and useful, (3) reduce the time it takes to 
disseminate the information and (4) achieve 95% statistical correlation 
between the O&D Survey and the T-100/T-100(f).

[[Page 31513]]

    In light of the responses to the NPRM, we have determined that it 
will be in the public interest to significantly modify our proposal to 
modernize aviation data products. We have also determined that an 
additional request for public comment based on the current proposal 
would not provide us with the information we need in order to 
accomplish our purpose.
    We have engaged a contractor with expertise in the industry to 
identify necessary and useful system features, and to address how data 
collection can be aligned with modern airline information technology so 
as to minimize the data-reporting burden on air carriers. Further, the 
contractor will assist the Department in assessing alternatives to the 
Department's proposal as stated in the NPRM that will help all 
stakeholders realize a better value for the investment in the data 
modernization effort.
    Although this rulemaking is being withdrawn, the Department 
anticipates the issuance at a later date of a new NPRM and will 
continue to involve the public in its effort to increase efficiency, 
effectiveness, integrity, quality, and utility of the aviation traffic 
information available, in a way that is also sensitive to the 
information collection costs that would be imposed on the carriers.
