ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 777–200, –200LR, –300ER, and 777F series airplanes. This AD was prompted by a report of a jettison fuel pump that was shut off by the automatic shutoff system during the center tank fuel scavenge process on a short-range flight and a subsequent failure analysis of the fuel scavenge system. This AD requires making wiring changes, modifying certain power panels, installing electrical load management system 2 (ELMS2) software, and accomplishing a functional test. We are issuing this AD to prevent extended dry running of the jettison fuel pumps, which can be a potential ignition source inside the main fuel tanks, and consequent fuel tank fire or explosion in the event that the jettison pump overheats or has an electrical fault. DATES: This AD is effective May 19, 2015. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of May 19, 2015.

The following presents the comments received on the NPRM and the FAA’s response to each comment. give credit for actions performed before the effective date of this AD using Boeing Special Attention Service Bulletin 777–28–0083, dated September 8, 2014, and have redesignated subsequent paragraphs accordingly. Concurrence With NPRM (79 FR 73252, December 10, 2014) FedEx stated that it concurs with the proposed requirements specified in NPRM (79 FR 73252, December 10, 2014). Request To Revise the Unsafe Condition Examining the AD Docket Request To Revise Costs of Compliance Section The Boeing Company (Boeing) requested that we revise the Costs of Compliance section of the NPRM (79 FR 73252, December 10, 2014). Boeing explained that the number of airplanes used in the cost estimate calculations is incorrect. For Groups 1 through 4 airplanes identified in Boeing Special Attention Service Bulletin 777–28– 0083, dated September 8, 2014, for which hardware and software changes are required, the number of affected U.S. registered airplanes is 9, instead of 7. For Group 5 airplanes, for which an ELMS2 software update is required, the number of affected U.S. registered airplanes is 2, not 4. We agree with the commenter. We have changed the number of airplanes in the ‘‘Costs of Compliance’’ section of this AD accordingly. We have also used information in Boeing Special Attention Service Bulletin 777–28–0083, Revision 1, dated March 6, 2015, to calculate the estimated costs.

SUPPLEMENTARY INFORMATION: asabaliauskas on DSK5VPTVN1PROD with RULES 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 777–200, –200LR, –300ER, and 777F series airplanes. The NPRM published in the Federal Register on December 10, 2014 (79 FR 73252). The NPRM was prompted by a report of a jettison fuel pump that was shut off by the automatic shutoff system during the center tank fuel scavenge process on a short-range flight. The NPRM proposed to require making wiring changes, modifying certain power panels, installing ELMS2 software, and accomplishing a functional test. We are issuing this AD to prevent extended dry running of the jettison fuel pumps, which can be a potential ignition source inside the main fuel tanks, and consequent fuel tank fire or explosion in the event that the jettison pump overheats or has an electrical fault. VerDate Sep<11>2014 16:01 Apr 13, 2015 Jkt 235001 Requests To Include Revised Service Information Boeing, All Nippon Airways (ANA), and FedEx requested that we revise the NPRM (79 FR 73252, December 10, 2014) to refer to a new revision of Boeing Special Attention Service Bulletin 777–28–0083. Boeing, ANA, and FedEx stated that a revised service bulletin is expected to be sent to the FAA before the release of this AD and that referencing the revised service bulletin would eliminate the need for alternative methods of compliance (AMOC) approval of the revised service bulletin. We agree with the commenters. Boeing has issued Special Attention Service Bulletin 777–28–0083, Revision 1, dated March 6, 2015. This service bulletin was revised to correct wire length and part numbers in wire kits. We have changed this AD to reference Boeing Special Attention Service Bulletin 777–28–0083, Revision 1, dated March 6, 2015, throughout. We have also added paragraph (h) of this AD to PO 00000 Frm 00009 Fmt 4700 Sfmt 4700 Boeing requested that we revise the unsafe condition, as described in paragraph (e) of the NPRM (79 FR 73252, December 10, 2014). Boeing stated that the fuel jettison pumps that are the subject of this AD are not a potential fuel tank ignition source because the pumps in question have been qualified to run dry without causing adverse pump operating temperatures for 600 hours. The jettison pump design includes redundant safety features to prevent fuel tank ignition. Boeing also stated that, based on service history and given the number of flight hours accrued by Model 777 airplanes, a conservative analysis shows the chance of a jettison pump running dry and causing a fuel tank ignition is less than extremely improbable. We disagree to revise the unsafe condition as stated in the Summary and paragraph (e) of this AD. We acknowledge that the fuel jettison pumps in question are properly qualified, and there is no known failure condition that could result in an ignition source. However, based on service experience of various types of fuel pumps, the FAA and industry may be unable to anticipate all of the possible mechanical and electrical failure modes of the fuel pumps that could result in an ignition source. For example, fuel pump qualification tests do not evaluate dry running of a fuel pump with debris ingested. Therefore, we have determined that extended dry running of the fuel jettison pump is a potential ignition source. We have made no changes to 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 (79 FR 73252, December 10, 2014) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (79 FR 73252, December 10, 2014). We also determined that these changes will not increase the economic E:\FR\FM\14APR1.SGM 14APR1 19880 Federal Register / Vol. 80, No. 71 / Tuesday, April 14, 2015 / Rules and Regulations burden on any operator or increase the scope of this AD. Related Service Information Under 1 CFR Part 51 We reviewed Boeing Special Attention Bulletin 777–28–0083, Revision 1, dated March 6, 2015. The service information describes, among other actions, procedures for making wiring changes to the engine fuel feed system, modifying certain power panels, installing ELMS2 software, and accomplishing a functional test. Refer to this service information for information on the procedures and compliance times. This service information is reasonably available; see ADDRESSES for ways to access this service information. Costs of Compliance We estimate that this AD affects 11 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Cost per product Action Labor cost Parts cost Group 1 through Group 4 airplanes: Hardware and software changes (9 airplanes). Group 5 airplanes: ELMS2 software update (2 airplanes). Up to 40 work-hours × $85 per hour = $3,400. Up to $1,461 ....... $4,861 8 work-hours × $85 per hour = $680 ....... 0 .......................... 680 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. asabaliauskas on DSK5VPTVN1PROD with RULES 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, VerDate Sep<11>2014 16:01 Apr 13, 2015 Jkt 235001 (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. Cost on U.S. operators Up to $43,749. 1,360. Service Bulletin 777–28–0083, Revision 1, dated March 6, 2015. (d) Subject Air Transport Association (ATA) of America Code 28: Fuel.

Amendment 39-18135; AD 2015-07-07]
RIN 2120-AA64


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 777-200, -200LR, -300ER, and 777F series 
airplanes. This AD was prompted by a report of a jettison fuel pump 
that was shut off by the automatic shutoff system during the center 
tank fuel scavenge process on a short-range flight and a subsequent 
failure analysis of the fuel scavenge system. This AD requires making 
wiring changes, modifying certain power panels, installing electrical 
load management system 2 (ELMS2) software, and accomplishing a 
functional test. We are issuing this AD to prevent extended dry running 
of the jettison fuel pumps, which can be a potential ignition source 
inside the main fuel tanks, and consequent fuel tank fire or explosion 
in the event that the jettison pump overheats or has an electrical 
fault.

DATES: This AD is effective May 19, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of May 19, 
2015.

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 777-200, -200LR, -300ER, and 777F series airplanes. The NPRM 
published in the Federal Register on December 10, 2014 (79 FR 73252). 
The NPRM was prompted by a report of a jettison fuel pump that was shut 
off by the automatic shutoff system during the center tank fuel 
scavenge process on a short-range flight. The NPRM proposed to require 
making wiring changes, modifying certain power panels, installing ELMS2 
software, and accomplishing a functional test. We are issuing this AD 
to prevent extended dry running of the jettison fuel pumps, which can 
be a potential ignition source inside the main fuel tanks, and 
consequent fuel tank fire or explosion in the event that the jettison 
pump overheats or has an electrical fault.

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.

Concurrence With NPRM (79 FR 73252, December 10, 2014)

    FedEx stated that it concurs with the proposed requirements 
specified in NPRM (79 FR 73252, December 10, 2014).

Request To Revise Costs of Compliance Section

    The Boeing Company (Boeing) requested that we revise the Costs of 
Compliance section of the NPRM (79 FR 73252, December 10, 2014). Boeing 
explained that the number of airplanes used in the cost estimate 
calculations is incorrect. For Groups 1 through 4 airplanes identified 
in Boeing Special Attention Service Bulletin 777-28-0083, dated 
September 8, 2014, for which hardware and software changes are 
required, the number of affected U.S. registered airplanes is 9, 
instead of 7. For Group 5 airplanes, for which an ELMS2 software update 
is required, the number of affected U.S. registered airplanes is 2, not 
4.
    We agree with the commenter. We have changed the number of 
airplanes in the ``Costs of Compliance'' section of this AD 
accordingly. We have also used information in Boeing Special Attention 
Service Bulletin 777-28-0083, Revision 1, dated March 6, 2015, to 
calculate the estimated costs.

Requests To Include Revised Service Information

    Boeing, All Nippon Airways (ANA), and FedEx requested that we 
revise the NPRM (79 FR 73252, December 10, 2014) to refer to a new 
revision of Boeing Special Attention Service Bulletin 777-28-0083. 
Boeing, ANA, and FedEx stated that a revised service bulletin is 
expected to be sent to the FAA before the release of this AD and that 
referencing the revised service bulletin would eliminate the need for 
alternative methods of compliance (AMOC) approval of the revised 
service bulletin.
    We agree with the commenters. Boeing has issued Special Attention 
Service Bulletin 777-28-0083, Revision 1, dated March 6, 2015. This 
service bulletin was revised to correct wire length and part numbers in 
wire kits. We have changed this AD to reference Boeing Special 
Attention Service Bulletin 777-28-0083, Revision 1, dated March 6, 
2015, throughout. We have also added paragraph (h) of this AD to give 
credit for actions performed before the effective date of this AD using 
Boeing Special Attention Service Bulletin 777-28-0083, dated September 
8, 2014, and have redesignated subsequent paragraphs accordingly.

Request To Revise the Unsafe Condition

    Boeing requested that we revise the unsafe condition, as described 
in paragraph (e) of the NPRM (79 FR 73252, December 10, 2014). Boeing 
stated that the fuel jettison pumps that are the subject of this AD are 
not a potential fuel tank ignition source because the pumps in question 
have been qualified to run dry without causing adverse pump operating 
temperatures for 600 hours. The jettison pump design includes redundant 
safety features to prevent fuel tank ignition. Boeing also stated that, 
based on service history and given the number of flight hours accrued 
by Model 777 airplanes, a conservative analysis shows the chance of a 
jettison pump running dry and causing a fuel tank ignition is less than 
extremely improbable.
    We disagree to revise the unsafe condition as stated in the Summary 
and paragraph (e) of this AD. We acknowledge that the fuel jettison 
pumps in question are properly qualified, and there is no known failure 
condition that could result in an ignition source. However, based on 
service experience of various types of fuel pumps, the FAA and industry 
may be unable to anticipate all of the possible mechanical and 
electrical failure modes of the fuel pumps that could result in an 
ignition source. For example, fuel pump qualification tests do not 
evaluate dry running of a fuel pump with debris ingested. Therefore, we 
have determined that extended dry running of the fuel jettison pump is 
a potential ignition source. We have made no changes to 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 (79 FR 73252, December 10, 2014) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (79 FR 73252, December 10, 2014).
    We also determined that these changes will not increase the 
economic

[[Page 19880]]

burden on any operator or increase the scope of this AD.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Special Attention Bulletin 777-28-0083, Revision 
1, dated March 6, 2015. The service information describes, among other 
actions, procedures for making wiring changes to the engine fuel feed 
system, modifying certain power panels, installing ELMS2 software, and 
accomplishing a functional test. Refer to this service information for 
information on the procedures and compliance times. This service 
information is reasonably available; see ADDRESSES for ways to access 
this service information.

Costs of Compliance

    We estimate that this AD affects 11 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------

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

    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.
