Final rule; request for comments.
This final rule adds a provision to the existing requirements for fuel tank system fault tolerance evaluations that allows type certificate holders to use equivalent safety provisions for demonstrating compliance. The current regulations do not provide such provisions. This rulemaking will allow current certificate holders to use the same equivalent safety provisions already available to applicants for new or changed type design approvals.

Amendment 25-102 and SRAF 88
Following the 1996 TWA 800 accident, which was caused by an explosion in the center wing fuel tank, the FAA promulgated rulemaking to establish several new transport airplane fuel tank safety requirements (66 FR 23086, May 7, 2001). The rulemaking which was effective June 6, 2001, included:
- Amendment 21-78 (SFAR 88) which requires type certificate (TC) and supplemental type certificate (STC) holders to conduct a revalidation of the fuel tank system designs on the existing fleet of transport category airplanes carrying 30 or more passengers or a payload of 7,500 lbs. or more; and to develop all design changes required to demonstrate they meet the new ignition prevention requirements and develop fuel tank maintenance and inspection instructions,
- Amendments 91-266, 121-282, 125-36, and 129-30, which require certain operators to incorporate FAA-approved fuel tank maintenance and inspection requirements into their maintenance or inspection programs, and
- Amendment 25-102, which includes ignition prevention design and maintenance requirements (§ 25.981(a) & (b) and paragraph H25.4 of appendix H), and fuel tank flammability requirements (§ 25.981(c)).Start Printed Page 57491
Discussion of SFAR 88 and This Amendment
SFAR 88 requires that holders of type certificates and supplemental type certificates review the designs of fuel tank systems of large transport category airplanes, and develop design changes and maintenance and inspection programs based on the findings of those reviews. The reviews are conducted using the identical ignition prevention requirements that were adopted for new or amended type designs in § 25.981. Reports documenting compliance are required to be submitted to the FAA by December 6, 2002.
During initial implementation of the rule, the FAA learned that mandating all the design changes required to meet the new safety assessment requirements of Amendment 25-102 for in-service airplanes, as required by SFAR 88, may not be needed to achieve the safety level intended by the rule. For example, the SFAR requires that design changes be developed to comply with the new design standard, § 25.981, which in turn requires that all possible ignition sources be eliminated from fuel systems. In the final rule preamble, we said that these design changes would be mandated by airworthiness directive (AD); however, ADs are issued only when we find an unsafe condition. This means that in some cases the SFAR would require development of design changes to address problems that are not serious enough (e.g., because of very low probabilities of occurrence) to warrant issuance of an AD. This result would be consistent with existing FAA policy that noncompliance with certification requirements is not by itself sufficient to establish an unsafe condition. The existing rule results in an unnecessary and inappropriate burden on industry to develop design changes that would never be required to be implemented. The cost of developing these changes would, therefore, not result in an improvement in safety and may divert resources needed to develop design changes that will be mandated via AD.
This new amendment will allow certificate holders to propose other means of demonstrating equivalent safety. For example, in the preamble to Amendment 25-102, the FAA discussed a change in philosophy regarding fuel tank safety. Data from past accidents indicated reduced fuel tank flammability, in combination with prevention of ignition sources, would provide the needed level of safety. Section 25.981(c) requires that fuel tank flammability be minimized.
The flammability level required by § 25.981(c) was based on the report of a 1998 industry advisory group that determined the flammability exposure of an unheated aluminum wing tank would provide an acceptable level of safety for all transport airplane fuel tanks. At the time of the rulemaking, however, the FAA did not have data to support rulemaking to require reduced fuel tank flammability on in-service airplanes. Since the rulemaking, FAA research into nitrogen inerting systems has shown that the practicality of incorporating nitrogen inerting systems into in-service airplanes has significantly improved. Type certificate holders may therefore wish to propose use of reduced fuel tank flammability to mitigate the need to make other more costly changes or implement expensive maintenance actions to prevent certain fuel tank ignition sources. This rulemaking will allow the FAA to consider these proposals that may well provide a better long-term solution to the fuel tank safety issues than that of ignition source prevention alone, as is currently require by SFAR 88.
The SFAR applies to two groups: current TC holders and applicants whose TC applications were pending on June 6, 2001, the SFAR's effective date. (All subsequent applicants are subject to the new part 25 standard.) [Note: In this discussion, STC holders are included in the term TC holders.] For TC applicants, the problem described above can be resolved under existing regulations. Specifically, § 21.21(b)(1) provides that the FAA can issue a TC if we find that standards “not complied with are compensated for by factors that provide an equivalent level of safety.” For example, an applicant for a TC whose application was submitted prior to June 6, 2001 (for which the flammability requirements of § 25.981(c) would not normally apply), may propose incorporation of a fuel tank nitrogen inerting system to provide an equivalent level of safety to certain portions of the fuel tank ignition source prevention requirements of Amendment 25-102 to § 25.981.
Since § 21.21 only applies to the issuance of TCs, this “equivalent safety” provision does not apply to current TC holders. Because this type of provision is needed for existing TCs at least as much as for pending applications, an immediately adopted “spot amendment” to the SFAR is necessary. This amendment adds a new provision to the SFAR that allows the FAA to approve a TC holder's required submission based on a finding that it provides an equivalent level of safety to full compliance with the SFAR. It would therefore provide a “level playing field” between pending applicants and current holders of TCs.
In originally adopting the SFAR, we anticipated neither the need for this provision, nor the difference in treatment between TC applicants and holders. Given the impending compliance deadline later this year, it would not be practicable to complete this rulemaking following notice and comment procedures in sufficient time to provide a meaningful alternative to TC holders. Good cause therefore exists for issuing this amendment without following those procedures.
Since this rule would simply make available to all persons subject to the SFAR an alternative that is currently available only to some, it is not “significant” for purposes of Executive Order 12866, DOT Regulatory Policies and Procedures, or the Regulatory Flexibility Act, and it does not require preparation of a regulatory evaluation.
Paperwork Reduction Act
There are no new requirements for information collection associated with this amendment.
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 determined that there are no ICAO Standards and Recommended Practices that correspond to these regulations.
Good Cause for Immediate Adoption
Sections 553(b)(3)(B) and 553(d)(3) of the Administrative Procedures Act (APA) (5 U.S.C. Sections 553(b)(3)(B) and 553(d)(3)) authorize agencies to dispense with certain notice procedures for rules when they find “good cause” to do so. Under section 553(b)(3)(B), the requirements of notice and opportunity for comment do not apply when the agency for good cause finds that those procedures are “impracticable, unnecessary, or contrary to the public interest.” Section 553(d)(3) allows an agency, upon finding good cause, to make a rule effective immediately, thereby avoiding the 30-day delayed effective date requirement in section 553.
The FAA finds that notice and public comments on this final rule are impracticable, unnecessary, and contrary to the public interest. For certificate holders to have sufficient time to take advantage of the alternative compliance methods allowed by this Start Printed Page 57492rule before the compliance deadline of December 6, 2002, this rule must adopted immediately. Notice and comment procedures would delay its adoption to the point where the rule would be of little value to them, thereby defeating the purpose of this rule. Therefore, notice and comment procedures are impracticable. Furthermore, as explained previously, this rule simply makes available to current certificate holders an alternative that is already provided to current certificate applicants by 14 CFR 21.21(b)(1).
Economic Evaluation, Regulatory Flexibility Determination, Trade Impact Assessment, and Unfunded Mandates Assessment
Changes to Federal regulations must undergo several economic analyses. First, Executive Order 12866 directs each Federal agency to 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. section 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, use them as the basis of U.S. standards. Fourth, the Unfunded Mandates Reform Act of 1995 (Pub. L. 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 $100 million or more annually (adjusted for inflation).
In conducting these analyses, the FAA has determined this rule (1) has benefits which justify its costs; (2) is not a “significant regulatory action” as defined in section 3(f) of Executive Order 12866 and is not “significant” as defined in DOT's Regulatory Policies and Procedures; (3) will not have a significant impact on a substantial number of small entities; (4) will have little effect on international trade; and (5) does not impose an unfunded mandate on State, local, or tribal governments, or on the private sector.
For regulations with an expected minimal impact, the above-specified analyses are not required. The Department of Transportation Order DOT 2100.5 prescribes policies and procedures for simplification, analysis, and review of regulations. If it is determined that the expected impact is so minimal that the proposal does not warrant a full evaluation, a statement to that effect and the basis for it is included in the proposed regulation. The FAA has determined that there are no costs associated with this final rule and the current level of safety is maintained. Instead, this rule change relieves holders of existing TCs from a cost that would have been inadvertently imposed on them in the adoption of the 2001 SFAR. This change effectuates the original intent of the 2001 SFAR.
Regulatory Flexibility Act
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 businesses, 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 RFA. If, however, 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 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.
This action will relieve unnecessary costs to holders of existing TCs. The FAA therefore expects this rule to impose no cost on small entities. Consequently, the FAA certifies that the rule will not have a significant economic impact on a substantial number of small entities.
Trade Impact Assessment
The Trade Agreement Act of 1979 prohibits Federal agencies from engaging in any standards or 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 rulemaking and has determined that it will reduce costs on holders of existing TCs and will have a minimal effect on international trade
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 as $100 million or more expenditure (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.”
This final rule does not contain such a mandate; therefore, the requirements of Title II of the Unfunded Mandates Reform Act of 1995 do not apply.
Executive Order 13132, Federalism
The FAA has analyzed this final rule under the principles and criteria of Executive Order 13132, Federalism. We determined that this action will not have a substantial direct effect on the States, or the relationship between the national Government and the States, or on the distribution of power and responsibilities among the various levels of government. We therefore determined that this final rule does not have federalism implications.
Executive Order 12866 (58 FR 51735, Oct. 4, 1993) requires each agency to write regulations that are simple and easy to understand. We invite your comments on how to make these regulations easier to understand, including answers to questions such as the following:
- Are the requirements in the regulation clearly stated?
- Does the regulation contain technical language or jargon that interferes with their clarity?
- Would the regulation be easier to understand if it was divided into more (but shorter) sections?
- Is the description in the premable helpful in understanding the regulation?Start Printed Page 57493

FAA Order 1050.1D defines FAA actions that may be categorically excluded from preparation of a National Environmental Policy Act (NEPA) environmental impact statement. In accordance with FAA Order 1050.1D, appendix 4, paragraph 4(j), this rulemaking action qualifies for a categorical exclusion.
The energy impact of the final rule has been assessed in accordance with the Energy Policy and Conservation Act (EPCA), Pub. L. 94-163, as amended (42 U.S.C. 6362), and FAA Order 1053.1. It has been determined that the final rule is not a major regulatory action under provisions of the EPCA.Start List of Subjects
