SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain The Boeing Company Model 787–8 airplanes. The NPRM published in the Federal Register on July 30, 2015 (80 FR 45460) (‘‘the NPRM’’). The NPRM was prompted by a report of fuel leaking onto the hot exhaust portion of an engine as a result of an unintended leak path from the leading edge through the pylon. The NPRM proposed to require installing new seal dams in the inboard and outboard corners of the aft pylon frame on the left and right engines, including an inspection for damage of the outboard blade seal and applicable corrective actions. We are issuing this AD to prevent fuel leaking from an unintended drain path from the leading edge through either the left or right pylon and onto the hot engine parts or brakes, which could lead to a major ground fire. mstockstill on DSK4VPTVN1PROD with RULES Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM and the FAA’s response to each comment. United Airlines concurred with the content of the NPRM. Request To Add Revised Service Information Boeing and All Nippon Airways (ANA) asked that we reference Boeing Alert Service Bulletin B787–81205– SB540004–00, Issue 002, dated VerDate Sep<11>2014 16:41 Mar 28, 2016 Jkt 238001 December 3, 2015, for accomplishing the actions in the NPRM. ANA stated that there are several errors in the referenced service information. Boeing stated that a revision would be issued to incorporate minor clarifications, and to update the effectivity. We agree to reference Boeing Alert Service Bulletin B787–81205– SB540004–00, Issue 002, dated December 3, 2015, in this AD. Since we published the NPRM, Boeing issued Alert Service Bulletin B787–81205– SB540004–00, Issue 002, dated December 3, 2015. That revision removes three airplanes from the effectivity, and clarifies certain instructions as a result of feedback reported by operators after incorporation of Boeing Alert Service Bulletin B787–81205–SB540004–00, Issue 001, dated October 24, 2014. Boeing Alert Service Bulletin B787– 81205–SB540004–00, Issue 001, dated October 24, 2014, was specified as the appropriate source of service information for accomplishing the actions in the NPRM. We have changed paragraphs (c) and (g) of this AD to specify Boeing Alert Service Bulletin B787–81205– SB540004–00, Issue 002, dated December 3, 2015. We have also added a new paragraph (h) of this AD to give credit for actions done before the effective date of this AD using Boeing Alert Service Bulletin B787–81205– SB540004–00, Issue 001, dated October 24, 2014; and redesignated subsequent paragraphs accordingly. Request To Reduce the Compliance Time The Air Line Pilots Association (ALPA) International asked that we reduce the compliance time specified in the proposed AD (the proposed compliance time is within 60 months after the effective date of this AD). ALPA stated that the severity of a fuel leak from the leading edge through the pylon and onto the hot exhaust part of the engines warrants a shorter compliance time to correct this problem. We do not agree with the commenter’s request to reduce the compliance time. In developing an appropriate compliance time, we considered the safety implications and normal maintenance schedules for timely installation of inboard and outboard seal dams. In consideration of all of these factors, we determined that the compliance time, as proposed, PO 00000 Frm 00010 Fmt 4700 Sfmt 4700 represents an appropriate interval in which the inboard and outboard seal dams can be installed in a timely manner within the fleet, while still maintaining an adequate level of safety. Most ADs, including this one, permit operators to accomplish the requirements of an AD at a time earlier than the specified compliance time; therefore, an operator may choose to install the inboard and outboard seal dams before the 60-month compliance time specified in paragraph (g) of this AD. If additional data are presented that would justify a shorter compliance time, we may consider further rulemaking on this issue. We have not changed this AD in this regard. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this 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 increase the economic burden on any operator or increase the scope of this AD. Related Service Information Under 1 CFR Part 51 We reviewed Boeing Alert Service Bulletin B787–81205–SB540004–00, Issue 002, dated December 3, 2015. This service information describes procedures for installing new seal dams in the inboard and outboard corners of the aft pylon frame on the left and right engines, doing a general visual inspection to detect damage of the outboard blade seal, and doing corrective actions. 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 affects 17 airplanes of U.S. registry. We estimate the following costs to comply with this AD: E:\FR\FM\29MRR1.SGM 29MRR1 Federal Register / Vol. 81, No. 60 / Tuesday, March 29, 2016 / Rules and Regulations 17371 ESTIMATED COSTS Action Labor cost Parts cost Cost per product Installation of seal dams ... Up to 22 work-hours × $85 per hour = $1,870. Up to $14,611 ................... Up to $16,481 ................... 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. 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. mstockstill on DSK4VPTVN1PROD with RULES 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.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Airbus Model A330– 200 and –300 series airplanes; and all Model A340–200, –300, –500, and –600 PO 00000 Frm 00012 Fmt 4700 Sfmt 4700 series airplanes. The NPRM published in the Federal Register on November 27, 2015 (80 FR 74042) (‘‘the NPRM’’). The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2015–0028R1, dated May 29, 2015, dated (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Airbus Model A330–200 and –300 series airplanes; and all Model A340–200, –300, –500, and –600 series airplanes. The MCAI states: Several cases have been reported in which the potable water service panel access door was lost during flight, causing damage to the trimmable horizontal stabilizer. The results of subsequent investigations showed that these events were due to failure of the latching mechanism of the potable water service panel access door. This condition, if not corrected, could lead to further cases of in-flight loss of the potable water service panel access door, possibly resulting in injury to persons on ground and/ or damage to the aeroplane [(e.g., damage to the trimmable horizontal stabilizer)]. To address this condition, Airbus developed a modification and published Service Bulletin (SB) A330–52–3086, SB A340–52–4094 and SB A340–52–5019, to provide instructions for in-service accomplishment of that modification. Consequently, EASA issued [an] AD * * * to require modification of the potable water service panel access door 164AR for A330/ A340–200/-300 aeroplanes or 154BR for A340–500/-600 aeroplanes, which includes installation of reinforced hinge screws and more robust latches. Since that [EASA] AD was issued, it was determined that aeroplanes that have embodied Airbus Mod 201938 (Improvement of latching mechanism of potable water service panel) are also not affected by the requirements of this [EASA] AD. For the reason described above, this [EASA] AD is revised to exclude post-mod 201938 aeroplanes from the Applicability. 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–2015– 5815. 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: E:\FR\FM\29MRR1.SGM 29MRR1

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
The Boeing Company Model 787-8 airplanes. This AD was prompted by a 
report of fuel leaking onto the hot exhaust portion of an engine as a 
result of an unintended leak path from the leading edge through the 
pylon. This AD requires installing new seal dams in the inboard and 
outboard corners of the aft pylon frame on the left and right engines, 
including an inspection for damage of the outboard blade seal and 
applicable corrective actions. We are issuing this AD to prevent fuel 
leaking from an unintended drain path from the leading edge through 
either the left or right pylon and onto the hot engine parts or brakes, 
which could lead to a major ground fire.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain The Boeing Company 
Model 787-8 airplanes. The NPRM published in the Federal Register on 
July 30, 2015 (80 FR 45460) (``the NPRM''). The NPRM was prompted by a 
report of fuel leaking onto the hot exhaust portion of an engine as a 
result of an unintended leak path from the leading edge through the 
pylon. The NPRM proposed to require installing new seal dams in the 
inboard and outboard corners of the aft pylon frame on the left and 
right engines, including an inspection for damage of the outboard blade 
seal and applicable corrective actions. We are issuing this AD to 
prevent fuel leaking from an unintended drain path from the leading 
edge through either the left or right pylon and onto the hot engine 
parts or brakes, which could lead to a major ground fire.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM and 
the FAA's response to each comment. United Airlines concurred with the 
content of the NPRM.

Request To Add Revised Service Information

    Boeing and All Nippon Airways (ANA) asked that we reference Boeing 
Alert Service Bulletin B787-81205-SB540004-00, Issue 002, dated 
December 3, 2015, for accomplishing the actions in the NPRM. ANA stated 
that there are several errors in the referenced service information. 
Boeing stated that a revision would be issued to incorporate minor 
clarifications, and to update the effectivity.
    We agree to reference Boeing Alert Service Bulletin B787-81205-
SB540004-00, Issue 002, dated December 3, 2015, in this AD. Since we 
published the NPRM, Boeing issued Alert Service Bulletin B787-81205-
SB540004-00, Issue 002, dated December 3, 2015. That revision removes 
three airplanes from the effectivity, and clarifies certain 
instructions as a result of feedback reported by operators after 
incorporation of Boeing Alert Service Bulletin B787-81205-SB540004-00, 
Issue 001, dated October 24, 2014. Boeing Alert Service Bulletin B787-
81205-SB540004-00, Issue 001, dated October 24, 2014, was specified as 
the appropriate source of service information for accomplishing the 
actions in the NPRM.
    We have changed paragraphs (c) and (g) of this AD to specify Boeing 
Alert Service Bulletin B787-81205-SB540004-00, Issue 002, dated 
December 3, 2015. We have also added a new paragraph (h) of this AD to 
give credit for actions done before the effective date of this AD using 
Boeing Alert Service Bulletin B787-81205-SB540004-00, Issue 001, dated 
October 24, 2014; and redesignated subsequent paragraphs accordingly.

Request To Reduce the Compliance Time

    The Air Line Pilots Association (ALPA) International asked that we 
reduce the compliance time specified in the proposed AD (the proposed 
compliance time is within 60 months after the effective date of this 
AD). ALPA stated that the severity of a fuel leak from the leading edge 
through the pylon and onto the hot exhaust part of the engines warrants 
a shorter compliance time to correct this problem.
    We do not agree with the commenter's request to reduce the 
compliance time. In developing an appropriate compliance time, we 
considered the safety implications and normal maintenance schedules for 
timely installation of inboard and outboard seal dams. In consideration 
of all of these factors, we determined that the compliance time, as 
proposed, represents an appropriate interval in which the inboard and 
outboard seal dams can be installed in a timely manner within the 
fleet, while still maintaining an adequate level of safety. Most ADs, 
including this one, permit operators to accomplish the requirements of 
an AD at a time earlier than the specified compliance time; therefore, 
an operator may choose to install the inboard and outboard seal dams 
before the 60-month compliance time specified in paragraph (g) of this 
AD. If additional data are presented that would justify a shorter 
compliance time, we may consider further rulemaking on this issue. We 
have not changed this AD in this regard.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this 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 increase the 
economic burden on any operator or increase the scope of this AD.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Alert Service Bulletin B787-81205-SB540004-00, 
Issue 002, dated December 3, 2015. This service information describes 
procedures for installing new seal dams in the inboard and outboard 
corners of the aft pylon frame on the left and right engines, doing a 
general visual inspection to detect damage of the outboard blade seal, 
and doing corrective actions. 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 affects 17 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

[[Page 17371]]



                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                 Cost on U.S.
             Action                   Labor cost          Parts cost       Cost per product        operators
----------------------------------------------------------------------------------------------------------------
Installation of seal dams.......  Up to 22 work-      Up to $14,611.....  Up to $16,481.....  Up to $280,177.
                                   hours x $85 per
                                   hour = $1,870.
----------------------------------------------------------------------------------------------------------------

    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.
    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.
