Service Difficulty Reports

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The Federal Aviation Administration is proposing to withdraw a 
final rule published on September 15, 2000 that would have amended the 
reporting requirements for certificate holders concerning failures, 
malfunctions, and defects of aircraft, aircraft engines, systems, and 
components. The effective date of this final rule has been delayed 
several times and is now January 31, 2006. We are proposing to withdraw 
this rule to allow the FAA time to re-examine the service difficulty 
report (SDR) program based on comments received and other developments 
since the final rule was published. We are also proposing several 
amendments that improve the existing SDR program because they did not 
receive significant comment when proposed in the final rule.

DATES: Send your comments on or before October 14, 2005.

Statutory Authority

    Title 49, 44701 of the United States Code, authorizes the 
Administrator of the Federal Aviation Administration to prescribe 
regulations for practices the Administrator finds necessary for safety 
in air commerce [49 U.S.C. 44701(a)(5)]. Pursuant to that statutory 
authority, the Administrator has prescribed regulations for certificate 
holders on the reporting of failures, malfunctions, and defects of 
aircraft, aircraft engines, systems, and components (commonly called 
Service Difficulty Reports). These regulations are found at 14 CFR 
121.703, 121.704, 121.705, 125.409, 125.410, 135.415, and 135.416. This 
action proposes amendments to those regulations.

Background

    On September 15, 2000, the FAA published a final rule (65 FR 56191) 
entitled, ``Service Difficulty Reports,'' Amendment Numbers 121-279, 
125-35, 135-77, and 145-22. That final rule, applicable to air carriers 
and certificated domestic and foreign repair station operators, amended 
the requirements for reporting failures, malfunctions, and defects of 
aircraft, aircraft engines, systems, and components. In the final rule, 
the FAA also sought comments on the impact of paperwork and other 
information collection burdens imposed on the public. The comment 
period closed on November 14, 2000, and the effective date was 
scheduled for January 16, 2001.
    The FAA received extensive written comments raising concerns with 
many of the provisions of the new SDR requirements. In response, the 
FAA held a public meeting about the final rule on December 11, 2000. 
Participants at that public meeting also raised significant issues 
concerning the implementation of the final rule.
    As a result of the concerns raised at the public meeting and during 
the comment period, the FAA delayed the effective date of the final 
rule to July 16, 2001. This effective date was subsequently delayed 
four more times (66 FR 21626, April 30, 2001/66 FR 58912, November 23, 
2001/67 FR 78970,

[[Page 54455]]

December 27, 2002/68 FR 75116, December 30, 2003). The current 
effective date is January 31, 2006. The purpose of these delays was to 
provide us more time to consider industry's concerns and to revise the 
final rule where necessary.
    Since the publication of the final rule, the FAA amended the SDR 
requirements for repair stations (66 FR 41117, August 6, 2001). Among 
other things, this amendment addressed one of the causes of potential 
duplicate reporting, as a part 145 certificate holder no longer has an 
independent reporting provision when performing work for a part 121, 
125, or 135 certificate holder.
    The FAA has also made improvements to the computer software and 
hardware that monitors SDRs. These changes are designed to facilitate 
searches of the SDR database and result in more useful results.

The Proposal To Withdraw the Final Rule

    The intent of the final rule was to improve the existing SDR 
program without having a significant adverse impact on industry. The 
new SDR requirements were designed to correct deficiencies in the SDR 
program and improve the quality of the data in the SDR database. 
However, based on the comments received and information gathered at the 
public meeting and during the comment period, we now realize the final 
rule may not meet these goals. The concerns raised by industry also 
highlighted the need to resolve problems with the existing SDR program 
before increasing the amount and type of data recorded.
    The topic that received the most comments was the FAA's economic 
analysis for the final rule. The commenters are uniform in their 
contention that the new reporting requirements will greatly increase 
the costs of the SDR program. The FAA received cost estimates from 
industry which considerably exceed our own estimates based, in part, on 
the wide disparity between the industry's and the FAA's evaluation of 
the number of SDRs resulting from the rulemaking.
    While not completely agreeing with the industry's estimate of the 
increase in the number of reports or the significant increase in costs, 
we have determined that some of the assumptions we used to predict the 
number of additional reports could have led industry to overestimate 
the costs of compliance with this rulemaking. We have reevaluated the 
final rule in light of the data provided in the comments and have 
determined that the costs of this rulemaking may be higher than 
projected. In addition, we acknowledge that populating data collection 
systems with inappropriate data could have a negative impact on the 
FAA's ability to identify and collect meaningful safety data on the 
operation of aircraft.
    Since the public meeting, we have considered ways to fix the final 
rule to maintain its original intent while addressing the concerns 
raised by industry. During this time period, the Commercial Airplane 
Certification Process Study (CPS) also issued its findings about the 
SDR program. The CPS was chartered by the FAA's Associate Administrator 
for Regulation and Certification in January 2001 to conduct a 
comprehensive review of the processes and procedures associated with 
aircraft certification, operations and maintenance. The CPS identified 
certain underlying deficiencies in the SDR program that should be 
corrected so data collected may provide the maximum safety benefit. A 
copy of the CPS report has been placed in the docket for this 
rulemaking.
    Based on the comments received and the CPS findings, the FAA has 
determined there is a need to enhance the SDR program so it meets the 
needs of the FAA and industry more efficiently and effectively. Rather 
than continuing to delay the effective date of the final rule while we 
address this issue, we believe it is prudent to withdraw the final 
rule. This approach will prevent uncertainty about the final rule's 
status and allows us time to thoroughly evaluate and improve the 
existing SDR program. The effect of a withdrawal will be the retention 
of the regulation currently in effect.

The Proposal for Amending the Current Rule

    The FAA is also proposing to make several minor changes to the 
existing SDR program. Most of these changes were already incorporated 
in the final rule we are now proposing to withdraw; we are proposing to 
proceed with these changes because they did not receive significant 
comment and will improve the SDR program.

Sections 121.703, 125.409, and 135.415

    The FAA is proposing to rename the titles of Sec. Sec.  121.703, 
125.409, and 135.415 to ``Service Difficulty Reports.'' The existing 
titles reflect the fact that these reports have been called various 
names over the years by different parties, resulting in some confusion. 
This proposed change would reflect the most common industry term for 
SDRs and result in the eventual use of only one consistently used term 
when referring to them.

Sections 121.703(d), 125.409(b), and 135.415(d)

    The FAA is proposing three changes to improve the process of 
submitting SDRs to the FAA under these sections:
    (1) Replacing the terms ``send,'' ``mailed,'' or ``delivered'' with 
the term ``submit.'' This change would allow for the use of other 
means, such as electronic transmission, to submit SDRs to the FAA.
    (2) Increasing the time for submitting an SDR from 72 hours to 96 
hours after an event occurs that requires an SDR. The increased 
reporting time gives certificate holders additional time to prepare the 
SDR and should reduce the number of supplemental SDRs that need to be 
filed. A reduction of supplemental SDRs should reduce the 
administrative burden on both the FAA and industry.
    (3) Changing the location to which the certificate holder must send 
SDRs. The current rule requires SDRs to be sent directly to the 
Certificate Holding District Office (CHDO). There, the SDRs are 
reviewed by the assigned Principal Maintenance Inspector (PMI) and then 
forwarded to the FAA offices in Oklahoma City, Oklahoma, where all SDRs 
are entered into the SDR database. The proposal would require the 
certificate holder to send SDRs directly to our Oklahoma City offices. 
The PMI would be instructed by internal agency procedures to review the 
individual SDR for their assigned certificate holder through an 
internal FAA computer system that would access the SDR database. This 
proposal would remove the intermediate step of processing SDRs through 
the PMI, but not relieve the PMI of the responsibility for reviewing 
them. The proposed change would also facilitate electronic reporting by 
eliminating the necessity of delivering a copy to the PMI. The 
certificate holder would retain the option of submitting paper SDRs 
should it so choose, although the FAA strongly encourages electronic 
reporting.
    Finally, for only Sec.  135.415, the FAA is proposing to remove the 
provision for aircraft operated where mail is not collected. This was 
an old provision that was rarely used by the industry. Mail service is 
available now in most locations and various alternatives to the U.S. 
Mail exist.

Section 121.703(e)

    The proposal would require certificate holders to submit SDRs in a 
form or format acceptable to the Administrator. Many operators have 
voluntarily adopted reporting formats compatible with the FAA's 
electronic systems to simplify their reporting under the

[[Page 54456]]

current rule. Electronic submission of SDRs through the FAA Web site is 
an acceptable format. This provision is intended to assure that, 
regardless of the method and format chosen for use, the information we 
receive is readable. However, when using electronic technology, the 
electronic language used must be one the FAA is capable of reading.

Paperwork Reduction Act

    The Paperwork Reduction Act of 1995 (44 U.S.C. 3507(d)) requires 
that the FAA consider the impact of paperwork and other information 
collection burdens imposed on the public. Information collection 
requirements associated with this NPRM have been approved previously by 
the Office of Management and Budget (OMB) under the provisions of the 
Paperwork Reduction Act of 1995 (44 U.S.C. 3507(d)) and have been 
assigned OMB Control Number 2120-0663. The proposals in this NPRM do 
not impose new information collection requirements on certificate 
holders.

International Compatibility

    In keeping with U.S. obligations under the Convention on 
International Civil Aviation, it is FAA policy to comply with 
International Civil Aviation Organization (ICAO) Standards and 
Recommended Practices to the maximum extent practicable. The FAA has 
determined that there are no ICAO Standards and Recommended Practices 
that correspond to these proposed regulations.

Regulatory Evaluation Summary

    Changes to Federal regulations must undergo several economic 
analyses. First, Executive Order 12866 directs that each Federal agency 
shall propose or adopt a regulation only upon a reasoned determination 
that the benefits of the intended regulation justify its costs. Second, 
the Regulatory Flexibility Act of 1980 requires agencies to analyze the 
economic impact of regulatory changes on small entities. Third, the 
Trade Agreements Act (19 U.S.C. 2531-2533) prohibits agencies from 
setting standards that create unnecessary obstacles to the foreign 
commerce of the United States. In developing U.S. standards, this Trade 
Act requires agencies to consider international standards and, where 
appropriate, to be the basis of U.S. standards. Fourth, the Unfunded 
Mandates Reform Act of 1995 (Public Law 104-4) requires agencies to 
prepare a written assessment of the costs, benefits, and other effects 
of proposed or final rules that include a Federal mandate likely to 
result in the expenditure by State, local, or tribal governments, in 
the aggregate, or by the private sector, of $120.7 million or more 
annually (adjusted for inflation.)
    In conducting these analyses, FAA has determined this proposed 
rule: (1) Has benefits that justify its costs, is not a ``significant 
regulatory action'' as defined in section 3(f) of Executive Order 
12866, and is not ``significant'' as defined in Department of 
Transportation Regulatory Policies and Procedures; (2) would not have a 
``significant economic impact on a substantial number of small 
entities;'' (3) would reduce barriers to international trade; and (4) 
would not impose an unfunded mandate on state, local, or tribal 
governments, or on the private sector. These analyses, available in the 
docket for this rulemaking, are summarized below.

Purpose of This Rulemaking

    This proposed rulemaking would withdraw a delayed final rule on 
Service Difficulty Reports (SDR), but retain several relieving items 
from that delayed final rule. The FAA is proposing to withdraw the 
delayed final rule because, after receipt of public comments on that 
action, the FAA has determined that its cost impact is greater than 
originally projected.

Total Costs and Benefits of This Rulemaking

Costs

    This proposed rule imposes minimal new costs on industry, and 
results in cost-savings ranging from $16.13 million ($11.33 million, 
discounted) to $38.96 million ($27.36 million, discounted). This 
results in a net cost savings to industry ranging from $15.98 million 
($11.23 million, discounted) to $38.97 million ($27.37 million, 
discounted). The impact to the FAA are additional costs of $145,200 
($102,000, discounted) and savings of $9,300 ($6,500, discounted). The 
FAA has determined this rule to be cost beneficial.

Benefits

    Currently, a significant effort is underway to improve the quality 
of aviation safety data identification and collection. This rulemaking 
is a component of this effort and proposes changes to improve the 
existing SDR program. These changes include:
    <bullet> Extending the reporting time to submit SDRs from 72 hours 
to 96 hours,
    <bullet> Requiring certificate holders to submit SDRs directly to a 
centralized collection point, thus allow the reports to be entered into 
the SDR database quicker and reduce the administrative workload of the 
certificate-holding district office (CHDO), and
    <bullet> Allowing electronic submission of SDR reports.

Regulatory Flexibility Determination

    The Regulatory Flexibility Act of 1980 (RFA) establishes ``as a 
principle of regulatory issuance that agencies shall endeavor, 
consistent with the objective of the rule and of applicable statutes, 
to fit regulatory and informational requirements to the scale of the 
business, organizations, and governmental jurisdictions subject to 
regulation.'' To achieve that principle, the RFA requires agencies to 
solicit and consider flexible regulatory proposals and to explain the 
rationale for their actions. The RFA covers a wide-range of small 
entities, including small businesses, not-for-profit organizations and 
small governmental jurisdictions.
    Agencies must perform a review to determine whether a proposed or 
final rule will have a significant economic impact on a substantial 
number of small entities. If the agency determines that it will, the 
agency must prepare a regulatory flexibility analysis as described in 
the Act.
    However, if an agency determines that a proposed or final rule is 
not expected to have a significant economic impact on a substantial 
number of small entities, section 605(b) of the 1980 RFA provides that 
the head of the agency may so certify and a regulatory flexibility 
analysis is not required. The certification must include a statement 
providing the factual basis for this determination, and the reasoning 
should be clear.
    For this rule, the small entity group is considered to be part 121, 
125, and 135 certificate holders (North American Industry 
Classification System [NAICS] 481111). For this analysis, the FAA 
considers each part 125 and 135 certificate holder to be a small 
entity, and some of the part 121 and 121/135 certificate holders are 
also small entities.
    These regulations result in cost savings for all certificate 
holders of between $16.13 million ($11.33 million, discounted) to 
$38.96 million ($27.36 million, discounted) over the next ten years or, 
on average, between $1.61 million to $3.90 million per year. Assuming 
that the cost savings is spread among the types of certificate holders 
in proportion to the number of SDRs each type generated from January 1, 
2002 through August 31, 2004, the average part 121 certificate holder 
would save between $13,010 and $31,424 a year, the average part 121/135 
certificate holder would save between $3,511 and $8,479

[[Page 54457]]

a year, the average part 125 certificate holder would save between $16 
and $39 a year, and the average part 135 certificate holder would save 
between $68 and $165 a year. Thus, the economic impact is minimal. 
Therefore, we certify that this action would not have a significant 
economic impact on a substantial number of small entities.

International Trade Impact Assessment

    The Trade Agreement Act of 1979 prohibits Federal agencies from 
establishing any standards or engaging in related activities that 
create unnecessary obstacles to the foreign commerce of the United 
States. Legitimate domestic objectives, such as safety, are not 
considered unnecessary obstacles. The statute also requires 
consideration of international standards and, where appropriate, that 
they be the basis for U.S. standards. The FAA has assessed the 
potential effect of this NPRM and has determined that it would have 
only a domestic impact and therefore no affect on any trade-sensitive 
activity.

Unfunded Mandates Assessment

    The Unfunded Mandates Reform Act of 1995 (the Act) is intended, 
among other things, to curb the practice of imposing unfunded Federal 
mandates on State, local, and tribal governments. Title II of the Act 
requires each Federal agency to prepare a written statement assessing 
the effects of any Federal mandate in a proposed or final agency rule 
that may result in an expenditure of $100 million or more (adjusted 
annually for inflation) in any one year by State, local, and tribal 
governments, in the aggregate, or by the private sector; such a mandate 
is deemed to be a ``significant regulatory action.'' The FAA currently 
uses an inflation-adjusted value of $120.7 million in lieu of $100 
million.
    This proposed rule does not contain such a mandate. The 
requirements of Title II do not apply.

Executive Order 13132, Federalism

    The FAA has analyzed this proposed rule under the principles and 
criteria of Executive Order 13132, Federalism. We determined that this 
action would not have a substantial direct effect on the States, on the 
relationship between the national Government and the States, or on the 
distribution of power and responsibilities among the various levels of 
government, and therefore would not have federalism implications.

Environmental Analysis

    FAA Order 1050.1E identifies FAA actions that are categorically 
excluded from preparation of an environmental assessment or 
environmental impact statement under the National Environmental Policy 
Act in the absence of extraordinary circumstances. The FAA has 
determined this proposed rulemaking action qualifies for the 
categorical exclusion and involves no extraordinary circumstances.

Regulations That Significantly Affect Energy Supply, Distribution, or 
Use

    The FAA has analyzed this NPRM under Executive Order 13211, Actions 
Concerning Regulations that Significantly Affect Energy Supply, 
Distribution, or Use (May 18, 2001). We have determined that it is not 
a ``significant energy action'' under the executive order because it is 
not a ``significant regulatory action'' under Executive Order 12866, 
and it is not likely to have a significant adverse effect on the 
supply, distribution, or use of energy.

International Compatibility

    In keeping with U.S. obligations under the Convention on 
International Civil Aviation, it is FAA policy to comply with 
International Civil Aviation Organization (ICAO) Standards and 
Recommended Practices to the maximum extent practicable. The FAA has 
determined that there are no ICAO Standards and Recommended Practices 
that correspond to these proposed regulations.
