SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2012–05–03, Amendment 39–16975 (77 FR 16143, March 20, 2012) (‘‘AD 2012–05–03’’). AD 2012–05–03 applied to certain The Boeing Company Model 747–100, 747– 100B, 747–100B SUD, 747–200B, 747– 200C, 747–200F, 747–300, 747–400, 747–400D, 747–400F, 747SR, and 747SP series airplanes. The NPRM published in the Federal Register on April 11, 2017 (82 FR 17403). The NPRM was prompted by a design review following a ground fire incident and reports of flammable fluid leaks from the wing leading edge area onto the engine exhaust area. The NPRM proposed to continue to require modifying the fluid drain path in the leading edge area of the wing. The NPRM also proposed to require additional work to seal those drainage holes in the wing access panels. We are issuing this AD to prevent flammable fluid from leaking onto the engine exhaust nozzle, which could result in a fire. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public. 41327 Conclusion We reviewed the relevant data and determined that air safety and the public interest require adopting this AD as proposed, except for 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. Related Service Information Under 1 CFR Part 51 We reviewed Boeing Special Attention Service Bulletin 747–57– 2332, Revision 2, dated February 22, 2016. This service information divides the affected airplanes into 10 groups. For all groups, this service information describes procedures for modifying the fluid drain path in the leading edge area of the wing. The modification consists of changing fluid dam assemblies at wing outboard leading edge station (OLES) 1250, and installing seal assemblies at OLES 1185. Additionally, this service information specifies changing the lower leading edge wing panels through repairs and installation of parts. For Groups 1 through 6 airplanes, this service information also specifies installing fluid dam assemblies at wing OLES 770. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. Costs of Compliance We estimate that this AD will affect 258 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Labor cost Fluid drainage modification (Groups 1–6) (143 airplanes) (actions retained from AD 2012–05–03). Fluid drainage modification (Groups 7–10) (115 airplanes) (actions retained from AD 2012–05–03). Drainage hole repair (258 airplanes) (new action) ................. nlaroche on DSKBBV9HB2PROD with RULES Action 95 work-hours × $85 per hour = $8,075. 90 work-hours × $85 per hour = $7,650. 2 work-hours × $85 per hour = $170. According to the manufacturer, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we VerDate Sep<11>2014 15:11 Aug 30, 2017 Jkt 241001 have included all costs in our cost estimate. Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue PO 00000 Frm 00007 Fmt 4700 Sfmt 4700 Cost per product Parts cost Cost on U.S. operators $33,609 $41,684 $5,960,812 29,304 36,954 4,249,710 9 179 46,182 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. E:\FR\FM\31AUR1.SGM 31AUR1 41328 Federal Register / Vol. 82, No. 168 / Thursday, August 31, 2017 / Rules and Regulations 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. This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes to the Director of the System Oversight Division. 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), (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. nlaroche on DSKBBV9HB2PROD with RULES List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

SUPPLEMENTARY INFORMATION: Discussion Airworthiness Directives; Dassault Aviation Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 7X airplanes. This AD was prompted by a discovery of noncompliant rivets in the flight deck upper skin. This AD requires replacement of noncompliant rivets. We are issuing this AD to address the unsafe condition on these products. DATES: This AD is effective October 5, 2017. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of October 5, 2017. ADDRESSES: For service information identified in this final rule, contact nlaroche on DSKBBV9HB2PROD with RULES SUMMARY: VerDate Sep<11>2014 15:11 Aug 30, 2017 Jkt 241001 We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Dassault Aviation Model FALCON 7X airplanes. The NPRM published in the Federal Register on May 31, 2017 (82 FR 24910) (‘‘the NPRM’’). The NPRM was prompted by a discovery of noncompliant rivets in the flight deck upper skin. The NPRM proposed to require replacement of noncompliant rivets. We are issuing this AD to prevent interference between the rivet shank and the flight deck mounted overhead panel when the flight deck upper skin deforms due to impact (e.g., bird strike). This condition, if not corrected, could affect the functioning of essential flight control systems, and result in reduced control of the airplane. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European PO 00000 Frm 00009 Fmt 4700 Sfmt 4700 41329 Union, has issued EASA Airworthiness Directive 2016–0124, dated June 22, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Dassault Aviation Model FALCON 7X airplanes. The MCAI states: During an internal review of the manufacturing files, it was found that 20 rivets installed on the cockpit [(flight deck)] upper skin are not compliant with the original type design. Those 20 MGPL type rivets have a shank longer than necessary and, in case of a bird strike under maximum energy impact, the cockpit upper skin deformation would lead to interference between the rivet shank and the cockpit mounted overhead panel. This condition, if not corrected, could affect the functioning of essential flight control systems, possibly resulting in reduced control of the aeroplane. To address this potential unsafe condition, Dassault Aviation published Service Bulletin (SB) F7X–176, providing instructions for replacement of the [noncompliant] rivets. For the reasons described above, this [EASA] AD requires removal of affected rivets and replacement with serviceable [solid-type] rivets compliant with original type design. You may examine the MCAI in the AD docket on the Internet at http:// www.regulations.gov by searching for and locating Docket No. FAA–2017– 0502. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public. Conclusion We reviewed the relevant data and determined that air safety and the public interest require adopting this AD as proposed except for 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. Related Service Information Under 1 CFR Part 51 Dassault Aviation has issued Service Bulletin 7X–176, dated February 3, 2016. This service information describes procedures for modifying the airplane by replacing certain blind rivets installed on the flight deck skin panel with solid-type rivets. This service information is reasonably available because the interested parties have access to it through their normal course E:\FR\FM\31AUR1.SGM 31AUR1

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2012-05-03, Amendment 39-16975 (77 FR 16143, 
March 20, 2012) (``AD 2012-05-03''). AD 2012-05-03 applied to certain 
The Boeing Company Model 747-100, 747-100B, 747-100B SUD, 747-200B, 
747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 
747SP series airplanes. The NPRM published in the Federal Register on 
April 11, 2017 (82 FR 17403). The NPRM was prompted by a design review 
following a ground fire incident and reports of flammable fluid leaks 
from the wing leading edge area onto the engine exhaust area. The NPRM 
proposed to continue to require modifying the fluid drain path in the 
leading edge area of the wing. The NPRM also proposed to require 
additional work to seal those drainage holes in the wing access panels. 
We are issuing this AD to prevent flammable fluid from leaking onto the 
engine exhaust nozzle, which could result in a fire.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this AD as proposed, except for 
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.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Special Attention Service Bulletin 747-57-2332, 
Revision 2, dated February 22, 2016. This service information divides 
the affected airplanes into 10 groups.
    For all groups, this service information describes procedures for 
modifying the fluid drain path in the leading edge area of the wing. 
The modification consists of changing fluid dam assemblies at wing 
outboard leading edge station (OLES) 1250, and installing seal 
assemblies at OLES 1185. Additionally, this service information 
specifies changing the lower leading edge wing panels through repairs 
and installation of parts.
    For Groups 1 through 6 airplanes, this service information also 
specifies installing fluid dam assemblies at wing OLES 770.
    This service information is reasonably available because the 
interested parties have access to it through their normal course of 
business or by the means identified in the ADDRESSES section.

Costs of Compliance

    We estimate that this AD will affect 258 airplanes of U.S. 
registry. We estimate the following costs to comply with this AD:

                                                 Estimated costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
                Action                         Labor cost           Parts cost        product        operators
----------------------------------------------------------------------------------------------------------------
Fluid drainage modification (Groups 1-  95 work-hours x $85 per          $33,609         $41,684      $5,960,812
 6) (143 airplanes) (actions retained    hour = $8,075.
 from AD 2012-05-03).
Fluid drainage modification (Groups 7-  90 work-hours x $85 per           29,304          36,954       4,249,710
 10) (115 airplanes) (actions retained   hour = $7,650.
 from AD 2012-05-03).
Drainage hole repair (258 airplanes)    2 work-hours x $85 per                 9             179          46,182
 (new action).                           hour = $170.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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.

[[Page 41328]]

    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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes to 
the Director of the System Oversight Division.

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),
    (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.
