SUPPLEMENTARY INFORMATION: E:\FR\FM\15JYR1.SGM 15JYR1 41674 Federal Register / Vol. 76, No. 136 / Friday, July 15, 2011 / Rules and Regulations Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an airworthiness directive (AD) that would apply to the specified products. That NPRM published in the Federal Register on December 1, 2010 (75 FR 74663). That NPRM proposed to require a general visual inspection to determine the routing of the wire bundles in the number two and number three engine pylons near the leading edge, and related investigative and corrective actions if necessary. For certain airplanes, that NPRM also proposed to require certain concurrent actions. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the proposal and the FAA’s response to each comment. Request To Change Wording of Precipitating Event Boeing requested a change to the wording describing the precipitating event specified in the Summary and Discussion sections and paragraph (e) of the NPRM to clarify the location of the fuel leak. Boeing clarified that, for the record, the fuel leaked from the main fuel feed tube and drained through the drain line. We agree that changing the language to specify the location of the leak makes the description more accurate. Therefore, we have changed the wording appropriately in the Summary section and paragraph (e) of this AD. However, the subject text does not appear in the Discussion section in the final rule. Request To Include Service Bulletin Reference in the ‘‘FAA’s Determination and Requirements of this Proposed AD’’ Paragraph of the NPRM Boeing requested that we change the last sentence of the ‘‘FAA’s Determination and Requirements of this Proposed AD’’ paragraph in the NPRM to cite the specific service bulletin number, revision level, and date to differentiate between previous and new service information. We agree that the requested change might clarify the information. However, because that section is not restated in the final rule, we cannot make the requested change to this AD. Request To Remove Cost of Concurrent Actions Boeing requested that we remove the cost of the concurrent inspection and bracket installation from the Costs of Compliance section of the NPRM. Boeing stated that the cost for the concurrent inspection and bracket installation was previously stated in AD 92–27–13, Amendment 39–8448 (58 FR 5920, January 25, 1993), and is not necessary in this proposed AD. We disagree that it is unnecessary to include the cost of the concurrent actions in this AD. We acknowledge that these costs have already been stated in an existing AD; however, we have provided costs for required actions in this AD, including concurrent actions, regardless of whether operators might already have done them. No change has been made to the AD in this regard. Request To Include On-Condition Costs Boeing stated that we should include the costs of inspecting the fuel feed tube and the alternating current motor driven hydraulic pump wire bundle, repairs, replacing the fuel tube, and changing the routing of the wire bundle to above the support bracket. We agree with the request to include the costs of these actions specified above. We have added an ‘‘On-condition costs’’ table to reflect these costs. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting the AD with the changes described previously— and minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM. We also determined that these changes will not significantly increase the economic burden on any operator or increase the scope of the AD. Costs of Compliance We estimate that this AD affects 15 airplanes of U.S. registry. We estimate the following costs to comply with this AD: TABLE—ESTIMATED COSTS Action Average labor rate per hour Work hours Inspection of wire routing ..................................... Concurrent Inspection and Bracket Installation ... We estimate the following costs to do any necessary inspections or repairs that would be required based on the results 1 9 Cost per product Parts $85 $85 $0 $0 of the required inspection.

However, we have been advised that the concurrent inspection and bracket installation have already E:\FR\FM\15JYR1.SGM 15JYR1 Federal Register / Vol. 76, No. 136 / Friday, July 15, 2011 / Rules and Regulations been done on some affected airplanes. Therefore, the future economic cost impact of this rule on U.S. operators is expected to be less than the cost impact figure indicated above. Effective Date (a) This AD is effective August 19, 2011. Bulletin 747–24A2168, Revision 3, dated July 29, 1993. Do all applicable related investigative and corrective actions before further flight. Doing the actions required by paragraph (c) of AD 92–27–13, Amendment 39–8448, is an acceptable method of compliance for the installation required by this paragraph. Note 1: For the purposes of this AD, a detailed inspection is: ‘‘An intensive examination of a specific item, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at an intensity deemed appropriate. Inspection aids such as mirror, magnifying lenses, etc., may be necessary. Surface cleaning and elaborate procedures may be required.’’ Affected ADs (b) AD 92–27–13, Amendment 39–8448, affects this AD. Credit for Actions Accomplished in Accordance With Previous Service Information Applicability (c) This AD applies to The Boeing Company Model 747–400 and –400D series airplanes, certificated in any category; as specified in Boeing Service Bulletin 747– 29A2114, Revision 1, dated July 15, 2010. (i) Actions accomplished before the effective date of this AD, in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin 747–29A2114, dated October 1, 2009, are considered acceptable for compliance with the corresponding actions specified in paragraph (g) of this AD. (j) Actions accomplished before the effective date of this AD, in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin 747–24A2168, Revision 1, dated December 5, 1991; or Revision 2, dated September 24, 1992; are considered acceptable for compliance with the corresponding actions specified in paragraph (h) of this AD. PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. 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. § 39.13 Regulatory Findings Unsafe Condition (e) This AD was prompted by a report of a fuel leak from the main fuel feed tube at the number two engine pylon. The Federal Aviation Administration is issuing this AD to detect and correct chafing of the main fuel feed tube and the alternating current motordriven hydraulic pump wire bundle, which could lead to arcing from the exposed wire to the fuel feed tube, and could result in a fire or explosion. 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), (3) Will not affect intrastate aviation in Alaska, and (4) 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. mstockstill on DSK4VPTVN1PROD with RULES List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

I. Background On July 21, 2010, President Obama signed into law the Dodd-Frank Act.1 As amended by the Dodd-Frank Act,2 the Commodity Exchange Act (‘‘CEA’’) provides that a person for which there is a Federal regulatory agency,3 including a broker-dealer registered under section 15(b) (except pursuant to paragraph (11) thereof) or 15C of the Exchange Act,4 shall not enter into, or offer to enter into, a transaction described in section 2(c)(2)(B)(i)(I) of the CEA with a person who is not an ‘‘eligible contract participant’’ 5 except 1 Public Law 111–203, 124 Stat. 1376. Law 111–203, § 742(c)(2) (to be codified at 7 U.S.C. 2(c)(2)(E)). 3 7 U.S.C. 2(c)(2)(E)(i), as amended by § 742(c) of the Dodd-Frank Act, defines a ‘‘Federal regulatory agency’’ to mean the Commodity Futures Trading Commission (‘‘CFTC’’), the Securities and Exchange Commission, an appropriate Federal banking agency, the National Credit Union Association, and the Farm Credit Administration. 4 7 U.S.C. 2(c)(2)(B)(i)(II). 5 ‘‘Eligible contract participant’’ (‘‘ECP’’) is defined in CEA section 1a(18), as re-designated and amended by section 721 of the Dodd-Frank Act. See Public Law 111–203, § 721 (amending CEA section 1a). The CEA’s definition of ECP generally is comprised of regulated persons; entities that meet a specified total asset test (e.g., a corporation, partnership, proprietorship, organization, trust, or other entity with total assets exceeding $10 million) or an alternative monetary test coupled with a nonmonetary component (e.g., an entity with a net worth in excess of $1 million and engaging in business-related hedging; or certain employee benefit plans, the investment decisions of which are made by one of four enumerated types of regulated 2 Public E:\FR\FM\15JYR1.SGM 15JYR1

Airworthiness Directives; The Boeing Company Model 747-400 and -
400D Series Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above. This AD requires a general visual inspection to 
determine the routing of the wire bundles in the number two and number 
three engine pylons near the leading edge, and related investigative 
and corrective actions if necessary. For certain airplanes, this AD 
also requires certain concurrent actions. This AD was prompted by a 
report of a fuel leak from the main fuel feed tube at the number two 
engine pylon. We are issuing this AD to detect and correct chafing of 
the main fuel feed tube and the alternating current motor-driven 
hydraulic pump wire bundle, which could lead to arcing from the exposed 
wire to the fuel feed tube, and could result in a fire or explosion.

DATES: This AD is effective August 19, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of August 19, 
2011.

SUPPLEMENTARY INFORMATION:

[[Page 41674]]

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an airworthiness directive (AD) that would apply to 
the specified products. That NPRM published in the Federal Register on 
December 1, 2010 (75 FR 74663). That NPRM proposed to require a general 
visual inspection to determine the routing of the wire bundles in the 
number two and number three engine pylons near the leading edge, and 
related investigative and corrective actions if necessary. For certain 
airplanes, that NPRM also proposed to require certain concurrent 
actions.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the proposal 
and the FAA's response to each comment.

Request To Change Wording of Precipitating Event

    Boeing requested a change to the wording describing the 
precipitating event specified in the Summary and Discussion sections 
and paragraph (e) of the NPRM to clarify the location of the fuel leak. 
Boeing clarified that, for the record, the fuel leaked from the main 
fuel feed tube and drained through the drain line.
    We agree that changing the language to specify the location of the 
leak makes the description more accurate. Therefore, we have changed 
the wording appropriately in the Summary section and paragraph (e) of 
this AD. However, the subject text does not appear in the Discussion 
section in the final rule.

Request To Include Service Bulletin Reference in the ``FAA's 
Determination and Requirements of this Proposed AD'' Paragraph of the 
NPRM

    Boeing requested that we change the last sentence of the ``FAA's 
Determination and Requirements of this Proposed AD'' paragraph in the 
NPRM to cite the specific service bulletin number, revision level, and 
date to differentiate between previous and new service information.
    We agree that the requested change might clarify the information. 
However, because that section is not restated in the final rule, we 
cannot make the requested change to this AD.

Request To Remove Cost of Concurrent Actions

    Boeing requested that we remove the cost of the concurrent 
inspection and bracket installation from the Costs of Compliance 
section of the NPRM. Boeing stated that the cost for the concurrent 
inspection and bracket installation was previously stated in AD 92-27-
13, Amendment 39-8448 (58 FR 5920, January 25, 1993), and is not 
necessary in this proposed AD.
    We disagree that it is unnecessary to include the cost of the 
concurrent actions in this AD. We acknowledge that these costs have 
already been stated in an existing AD; however, we have provided costs 
for required actions in this AD, including concurrent actions, 
regardless of whether operators might already have done them. No change 
has been made to the AD in this regard.

Request To Include On-Condition Costs

    Boeing stated that we should include the costs of inspecting the 
fuel feed tube and the alternating current motor driven hydraulic pump 
wire bundle, repairs, replacing the fuel tube, and changing the routing 
of the wire bundle to above the support bracket.
    We agree with the request to include the costs of these actions 
specified above. We have added an ``On-condition costs'' table to 
reflect these costs.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
the AD with the changes described previously--and minor editorial 
changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    We also determined that these changes will not significantly 
increase the economic burden on any operator or increase the scope of 
the AD.

Costs of Compliance

    We estimate that this AD affects 15 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                                 Table--Estimated Costs

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

    We estimate the following costs to do any necessary inspections or 
repairs that would be required based on the results of the required 
inspection. We have no way of determining the number of aircraft that 
might need these inspections or repairs:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
                                                                   Average labor                     Cost per

----------------------------------------------------------------------------------------------------------------
Inspection of wire bundle and fuel feed tube....               3             $85              $0            $255
Repair of wire bundle, repair or replacement of                7             $85             $26            $621
 fuel feed tube, and wire bundle routing change.
----------------------------------------------------------------------------------------------------------------

    The cost estimate figures discussed above are based on assumptions 
that no operator has yet accomplished any of the actions required by 
this AD, and that no operator would accomplish those actions in the 
future if this AD were not adopted. However, we have been advised that 
the concurrent inspection and bracket installation have already

[[Page 41675]]

been done on some affected airplanes. Therefore, the future economic 
cost impact of this rule on U.S. operators is expected to be less than 
the cost impact figure indicated above.

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

    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),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) 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.
