Download as PDF 64130 Federal Register / Vol. 72, No. 220 / Thursday, November 15, 2007 / Rules and Regulations external auditor generally disclaims an opinion when significant limitations prevent him from performing all the tests necessary to complete the audit and render an opinion. Auditing Standard No. 5 also requires the external auditor to modify his or her opinion on the effectiveness of internal control over financial reporting if the auditor determines that management’s assessment is not fairly stated. rfrederick on PROD1PC67 with RULES II. Funding Corporation External Auditor’s Attestation of Internal Control Over Financial Reporting The FCA is amending § 630.5(d)(2) to conform with applicable industry standards for auditor attestations on internal control over financial reporting. The requirement in § 630.5(d)(2) for the external auditor of the Funding Corporation to review, attest, and report on management’s assessment of internal control over financial reporting is no longer consistent with industry standards. Industry standards now require attestation reports to opine on the effectiveness of internal control over financial reporting. The amendment in this rulemaking will conform with these new standards. The provision of § 630.5(d)(2), as amended by this direct final rulemaking, requires the external auditor of the Funding Corporation to include in the attestation report, an opinion on the effectiveness of internal control over financial reporting. The revised requirement reduces confusion, clarifies reporting, and more effectively communicates the external auditor’s responsibility in relation to management’s process and necessarily conveys whether management’s assessment is fairly stated. III. Direct Final Rule We are amending § 630.5(d)(2) by a direct final rulemaking. The Administrative Conference of the United States recommends direct final rulemaking for Federal agencies to enact noncontroversial regulations on an expedited basis, without the usual notice and comment period.5 This process enables us to reduce the time and resources we need to develop, review, and publish a final rule while still affording the public an adequate opportunity to comment or object to the rule. In a direct final rulemaking, we notify the public that the rule will become final on a specified future date unless we receive significant adverse comment 5 Recommendation 95–4, referencing the Administrative Procedure Act ‘‘good cause’’ exemption at 5 U.S.C. 553(b)(B), (adopted June 15, 1995). VerDate Aug<31>2005 15:27 Nov 14, 2007 Jkt 214001 during the comment period. A significant adverse comment is one where the commenter explains why the rule would be inappropriate (including challenges to its underlying premise or approach), ineffective, or unacceptable without a change. In general, a significant adverse comment would raise an issue serious enough to warrant a substantive response from the agency in a notice-and-comment proceeding. We believe that a direct final rulemaking is the appropriate method for amending § 630.5(d)(2) to conform to new industry standards. We do not anticipate there will be significant adverse comments. We received no objectionable comments to the December 2006 rulemaking that added the requirement for an external auditor attestation, which conformed with SEC requirements at the time. Further, we stated at that time our intent to remain consistent with industry standards in this area, and commenters agreed. If, however, we receive a significant adverse comment during the comment period, we will publish a notice of withdrawal of the relevant provisions of this rule that will also indicate how further rulemaking will proceed. If we receive no significant adverse comment, we will publish notice of the effective date of the rule following the required Congressional waiting period under section 5.17(c)(1) of the Farm Credit Act of 1971, as amended. IV. Regulatory Flexibility Act Pursuant to section 605(b) of the Regulatory Flexibility Act (5 U.S.C. 601 et seq.), FCA hereby certifies that the direct final rule will not have a significant economic impact on a substantial number of small entities. Each of the banks in the Farm Credit System, considered together with its affiliated associations, has assets and annual income in excess of the amounts that would qualify them as small entities. Therefore, Farm Credit System institutions are not ‘‘small entities’’ as defined in the Regulatory Flexibility Act.

ACTION: Final rule. AGENCY: SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 747–400, 747–400D, 747– 400F, 757–200, 767–200, 767–300, and 767–300F series airplanes. This AD requires inspecting to determine the date code of the time delay relay for the cargo fire suppression system, and E:\FR\FM\15NOR1.SGM 15NOR1 Federal Register / Vol. 72, No. 220 / Thursday, November 15, 2007 / Rules and Regulations replacing the relay if necessary. This AD results from a report indicating that failure of a time delay relay on an ELMS (electrical load management system) panel led to testing of other time delay relays at Boeing and at the supplier. Similar relays are used in the cargo fire suppression system. The time delay relay controls when the secondary fire bottles discharge. We are issuing this AD to ensure there is sufficient fire suppressant to control a cargo fire if the airplane is more than the relay delay time from a suitable airport, which could result in an uncontrollable fire in the cargo compartment.

SUPPLEMENTARY INFORMATION: rfrederick on PROD1PC67 with RULES Discussion The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to certain Boeing Model 747–400, 747–400D, 747–400F, 757–200, 767– 200, 767–300, and 767–300F series airplanes. That NPRM was published in the Federal Register on July 3, 2007 (72 FR 36378). That NPRM proposed to require inspecting to determine the date code of the time delay relay for the cargo fire suppression system, and replacing the relay if necessary. VerDate Aug<31>2005 15:27 Nov 14, 2007 Jkt 214001 Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comments received. Request To Revise Applicability ABX Air states that it removed the affected relay from its Boeing Model 767–200 airplanes in accordance with Boeing Service Bulletin 767–26–0016, and therefore cannot perform the proposed requirements. ABX requests that we state in the AD that the proposed requirements apply only to airplanes with the time delay relay installed. We agree that the AD does not apply to airplanes that do not have the time delay relay installed. However, we disagree with the request to change the AD to specify that it does not apply to airplanes with the relay removed. Paragraph (g) of the AD requires an inspection of specific relays and notes the part numbers. If that part number is not installed on the airplane, the airplane is not subject to the replacement requirements of paragraph (h) of the AD. We have not changed the AD in this regard. Request To Revise Summary Boeing requests that we revise the Summary section of the NPRM to clarify which bottles are discharged by the time delay relay. Specifically Boeing requests that we add the word ‘‘secondary’’ as shown in the following sentence: ‘‘The time delay relay controls when the secondary fire bottles discharge.’’ We agree that the addition of the word ‘‘secondary’’ clarifies the sentence. We have changed the Summary section of the AD as requested. We have also added the sentence to paragraph (d) of the AD for clarity. Request To Clarify Discussion Section Boeing requests that we clarify the second paragraph of the Discussion section of the NPRM because that paragraph states that the listed airplanes have two halon bottles. Boeing states that some of the systems have more than two halon bottles. We agree that Boeing’s clarification improves the paragraph. However, since that section of the preamble does not reappear in the final rule, no change to the final rule is necessary. Explanation of Editorial Changes As requested by Boeing, we have added an ‘‘in’’ before the words ‘‘Table 1’’ in paragraph (c) of this AD, and we have added the word ‘‘an’’ before the words ‘‘uncontrollable fire’’ in paragraph (d) of this AD. PO 00000 Frm 00013 Fmt 4700 Sfmt 4700 64131 Conclusion We have carefully reviewed the available data, including the comments received, and determined that air safety and the public interest require adopting the AD with the changes described previously. We have determined that these changes will neither increase the economic burden on any operator nor increase the scope of the AD. Costs of Compliance There are about 1,871 airplanes of the affected design in the worldwide fleet. This AD affects about 702 airplanes of U.S. registry. The inspection takes about 1 work hour per airplane, at an average labor rate of $80 per work hour. Based on these figures, the estimated cost of the AD for U.S. operators is $56,160, or $80 per airplane. Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. Subtitle I, Section 106, describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the Agency’s authority. We are issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701, ‘‘General requirements.’’ Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. Regulatory Findings We have determined that this AD will not have federalism implications under Executive Order 13132. This AD will 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. For the reasons discussed above, I certify that this AD: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866; (2) Is not a ‘‘significant rule’’ under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and (3) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

SUPPLEMENTARY INFORMATION: 

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that would apply to certain Boeing Model 
747-400, 747-400D, 747-400F, 757-200, 767-200, 767-300, and 767-300F 
series airplanes. That NPRM was published in the Federal Register on 
July 3, 2007 (72 FR 36378). That NPRM proposed to require inspecting to 
determine the date code of the time delay relay for the cargo fire 
suppression system, and replacing the relay if necessary.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comments received.

Request To Revise Applicability

    ABX Air states that it removed the affected relay from its Boeing 
Model 767-200 airplanes in accordance with Boeing Service Bulletin 767-
26-0016, and therefore cannot perform the proposed requirements. ABX 
requests that we state in the AD that the proposed requirements apply 
only to airplanes with the time delay relay installed.
    We agree that the AD does not apply to airplanes that do not have 
the time delay relay installed. However, we disagree with the request 
to change the AD to specify that it does not apply to airplanes with 
the relay removed. Paragraph (g) of the AD requires an inspection of 
specific relays and notes the part numbers. If that part number is not 
installed on the airplane, the airplane is not subject to the 
replacement requirements of paragraph (h) of the AD. We have not 
changed the AD in this regard.

Request To Revise Summary

    Boeing requests that we revise the Summary section of the NPRM to 
clarify which bottles are discharged by the time delay relay. 
Specifically Boeing requests that we add the word ``secondary'' as 
shown in the following sentence: ``The time delay relay controls when 
the secondary fire bottles discharge.''
    We agree that the addition of the word ``secondary'' clarifies the 
sentence. We have changed the Summary section of the AD as requested. 
We have also added the sentence to paragraph (d) of the AD for clarity.

Request To Clarify Discussion Section

    Boeing requests that we clarify the second paragraph of the 
Discussion section of the NPRM because that paragraph states that the 
listed airplanes have two halon bottles. Boeing states that some of the 
systems have more than two halon bottles.
    We agree that Boeing's clarification improves the paragraph. 
However, since that section of the preamble does not reappear in the 
final rule, no change to the final rule is necessary.

Explanation of Editorial Changes

    As requested by Boeing, we have added an ``in'' before the words 
``Table 1'' in paragraph (c) of this AD, and we have added the word 
``an'' before the words ``uncontrollable fire'' in paragraph (d) of 
this AD.

Conclusion

    We have carefully reviewed the available data, including the 
comments received, and determined that air safety and the public 
interest require adopting the AD with the changes described previously. 
We have determined that these changes will neither increase the 
economic burden on any operator nor increase the scope of the AD.

Costs of Compliance

    There are about 1,871 airplanes of the affected design in the 
worldwide fleet. This AD affects about 702 airplanes of U.S. registry. 
The inspection takes about 1 work hour per airplane, at an average 
labor rate of $80 per work hour. Based on these figures, the estimated 
cost of the AD for U.S. operators is $56,160, or $80 per airplane.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, Section 106, describes the 
authority of the FAA Administrator. Subtitle VII, Aviation Programs, 
describes in more detail the scope of the Agency's authority.
    We are issuing this rulemaking under the authority described in 
Subtitle VII, Part A, Subpart III, Section 44701, ``General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    We have determined that this AD will not have federalism 
implications under Executive Order 13132. This AD will 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.
    For the reasons discussed above, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866;
    (2) Is not a ``significant rule'' under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979); and
    (3) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket. See the ADDRESSES 
section for a location to examine the regulatory evaluation.

Unsafe Condition

    (d) This AD results from a report indicating that failure of a 
time delay relay on a Boeing Model 777 ELMS (electrical load 
management system) panel led to testing of other time delay relays 
at Boeing and at the supplier. Similar relays are used in the cargo 
fire suppression system. The time delay relay controls when the 
secondary fire bottles discharge. We are issuing this AD to ensure 
there is sufficient fire suppressant to control a cargo fire if the 
airplane is more than the relay delay time from a suitable airport, 
which could result in an uncontrollable fire in the cargo 
compartment.

Compliance

    (e) You are responsible for having the actions required by this 
AD performed within the compliance times specified, unless the 
actions have already been done.

Service Bulletin Reference

    (f) The term ``service bulletin,'' as used in this AD, means the 
Accomplishment Instructions of the following service bulletins, as 
applicable:
    (1) For Model 747-400, 747-400D, and 747-400F series airplanes:

Special Attention Service Bulletin 767-26-0131, dated July 24, 2006.

Inspection

    (g) Within 24 months after the effective date of this AD: Do a 
general visual inspection of the part number (P/N) TDH6103-1204, -
1804, and -6003 time delay relay, as applicable, in the main 
equipment center to determine if the relay was manufactured during a 
certain date range, in accordance with the applicable service 
bulletin.

Replacement

    (h) Within 30 days after finding a relay manufactured during the 
date range specified in the service bulletin, as required by 
paragraph (g) of this AD: Replace the relay with a relay that was 
not manufactured during the specified date range, or with a relay 
that has been tested by the supplier and found to be unaffected by 
thermal expansion, in accordance with the applicable service 
bulletin.

Parts Installation

    (i) As of the effective date of this AD, no person may install a 
time delay relay, P/N TDH6103-1204, -1804, or -6003, on any airplane 
if the relay has a date code between 0000 and 0343 and does not have 
an additional date code with the letter ``T.''

Alternative Methods of Compliance (AMOCs)

    (j)(1) The Manager, Seattle Aircraft Certification Office, FAA, 
has the authority to approve AMOCs for this AD, if requested in 
accordance with the procedures found in 14 CFR 39.19.
