Federal Register Volume 81, Issue 105 (June 1, 2016)

We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 777 airplanes. This AD was prompted by reports of unreliable performance of the fuel scavenge system. This AD requires changing the main fuel tank water scavenge system, center fuel tank fuel scavenge system, and certain electrical panels; doing related investigative actions; doing corrective actions if necessary; and, for certain airplanes, changing the fuel scavenge system to give redundant control of the center override/jettison fuel pumps and main jettison fuel pumps. We are issuing this AD to prevent fuel exhaustion and subsequent power loss of all engines due to loss of capability to scavenge fuel in the center fuel tank.

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
The Boeing Company Model 777 airplanes. This AD was prompted by reports 
of unreliable performance of the fuel scavenge system. This AD requires 
changing the main fuel tank water scavenge system, center fuel tank 
fuel scavenge system, and certain electrical panels; doing related 
investigative actions; doing corrective actions if necessary; and, for 
certain airplanes, changing the fuel scavenge system to give redundant 
control of the center override/jettison fuel pumps and main jettison 
fuel pumps. We are issuing this AD to prevent fuel exhaustion and 
subsequent power loss of all engines due to loss of capability to 
scavenge fuel in the center fuel tank.

DATES: This AD is effective July 6, 2016.

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 airplanes. The NPRM published in the Federal Register on May 
14, 2015 (80 FR 27601) (``the NPRM''). The NPRM was prompted by reports 
of unreliable performance of the fuel scavenge system. The NPRM 
proposed to require changing the main fuel tank water scavenge system, 
center fuel tank fuel scavenge system, and certain electrical panels; 
related investigative actions; and doing corrective actions if 
necessary; and, for certain airplanes, changing the fuel scavenge 
system to give redundant control of the center override/jettison fuel 
pumps and main jettison fuel pumps. We are issuing this AD to prevent 
fuel exhaustion and subsequent power loss of all engines due to loss of 
capability to scavenge fuel in the center fuel tank.

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.

Request To Withdraw the NPRM

    Lufthansa Cargo AG stated that the unsafe condition addressed in 
the NPRM is not a safety concern and that mandating Boeing Special 
Attention Service Bulletin 777-28-0078, dated September 4, 2014, is not 
justified. Lufthansa Cargo AG stated that the main fuel tanks must be 
fully loaded with fuel when a mission flight requires fuel in the 
center tank. Lufthansa Cargo AG explained that if the fuel scavenge 
system fails to scavenge the remaining fuel in the center tank, the 
fuel in the main tanks is still available, and therefore there is no 
safety concern.
    We infer that the commenter requests we withdraw the NPRM. We do 
not agree with the commenter's request. The failure of fuel scavenging 
means that up to 2,700 pounds of fuel that is required by mission 
planning would not be available if needed. The actions required by this 
AD are necessary in order to prevent fuel exhaustion and subsequent 
power loss of all engines due to loss of capability to scavenge fuel in 
the center fuel tank. We have not changed this AD in this regard.

Requests To Remove Modification Requirement

    Boeing, Aerologic GmbH, and British Airways (BAC) requested that we 
remove the modification required by paragraph (g) of the proposed AD, 
but instead mandate installation of airplane information management 
system (AIMS) 2 software V14 or later to address the unsafe condition. 
Aerologic GmbH and BAC stated that the unsafe condition can be 
mitigated by incorporation of AIMS 2 software Vl4 or later, which 
provides an engine indicating and crew alerting system (EICAS) advisory 
message to alert the flightcrew of the status of the scavenge system 
and the possibility of unusable trapped fuel. Boeing stated that the 
trapped fuel quantity is well below reserve fuel requirements and that 
the flightcrew can take appropriate actions to avoid a fuel exhaustion 
condition.
    We do not agree with the commenters' request. We worked with Boeing 
extensively on this issue in order to define a reliable automated 
solution, appropriate to address the severity of this safety issue. 
While Boeing may disagree, we have determined that relying solely on 
AIMS 2 software V14 or later is not sufficient to address the 
identified unsafe condition under all flight conditions. The approach 
in Boeing Special Attention Service Bulletin 777-28-0078, Revision 1, 
dated April 27, 2015, yields a higher confidence of fully mitigating 
the safety issue since a robust automated software solution (i.e., 
installing electrical load management system 2 (ELMS 2) software) 
removes the potential for human error to undermine the safety 
mitigation. We have not changed this AD in this regard.

Request To Delay AD Issuance

    Boeing requested that we delay issuance of the final rule until the 
modified scavenge system is certified on Model 777 airplanes equipped 
with an auxiliary fuel tank. Boeing stated that this will allow this 
final rule to require the accomplishment of Boeing Service Bulletin 
777-28-0078 on all applicable airplanes and avoid the need for multiple 
ADs on the same subject.
    We infer the commenter is requesting that we delay issuance of the 
final rule until a revision of Boeing Service Bulletin 777-28-0078 is 
available for

[[Page 34869]]

reference in the final rule. We do not agree with the commenter's 
request. We do not have a definitive date when the modified scavenge 
system will be certified on Model 777 airplanes equipped with an 
auxiliary fuel tank and the related service bulletin revision will be 
available. To delay this action would be inappropriate, since we have 
determined that an unsafe condition exists. We have also determined 
that it is not warranted to delay this final rule in order to avoid 
issuance of multiple ADs on the same subject. We have not changed this 
AD in this regard.

Requests To Incorporate New Service Information and Provide Credit

    Boeing, All Nippon Airways (ANA), Delta Airlines (DAL), Emirates 
Airline, FedEx Express, and United Airlines (UAL) requested that we 
revise the NPRM to incorporate Boeing Special Attention Service 
Bulletin 777-28-0078, Revision 1, dated April 27, 2015. Boeing 
requested that we provide credit for prior actions done using Boeing 
Special Attention Service Bulletin 777-28-0078, dated September 4, 
2014.
    We agree with the commenters' requests. Boeing Special Attention 
Service Bulletin 777-28-0078, Revision 1, dated April 27, 2015, 
provides revised instructions and top-kits to accomplish the 
modification. No new work is required by this revision. We have revised 
paragraphs (c), (g), (h)(1), (h)(2), and (i) of this AD to refer to 
Boeing Special Attention Service Bulletin 777-28-0078, Revision 1, 
dated April 27, 2015. We have added new paragraph (j)(2) of this AD to 
provide credit for actions required by paragraph (g) of this AD, if 
those actions were performed before the effective date of this final 
rule using Boeing Special Attention Service Bulletin 777-28-0078, dated 
September 4, 2014. We have redesignated paragraph (j) of the proposed 
AD as paragraph (j)(1) in this AD.

Request To Revise Compliance Time

    Boeing requested that we remove the wording ``prior to'' in 
paragraph (h)(2) of the proposed AD, which would require actions to be 
done concurrently with the actions specified in paragraph (g) of the 
proposed AD.
    We agree with the commenter's request. Boeing Special Attention 
Service Bulletin 777-28-0078, Revision 1, dated April 27, 2015, 
specifies concurrent, not prior, accomplishment of the service 
information specified in paragraph (h) of this AD. We have revised 
paragraph (h) of this AD accordingly, which does not expand the 
requirements of this AD.

Requests To Incorporate Boeing Information Notice (IN) for New Service 
Bulletin, for Part Substitution, and for Error Resolution

    ANA, DAL, Emirates Airline, FedEx, and UAL requested that we 
include in the NPRM the information specified in Boeing IN 777-28-0078 
IN 02. FedEx also requested that we include in the NPRM the information 
specified in Boeing IN 777-28-0078 IN 03. ANA and Emirates Airline 
requested that a new Boeing Service Bulletin (Revision 2 of Boeing 
Service Bulletin 777-28-0078) be mandated if possible.
    The commenters stated that Boeing IN 777-28-0078 IN 02 clarifies 
the instructions in Boeing Special Attention Service Bulletin 777-28-
0078, and also indicates that Boeing Special Attention Service Bulletin 
777-28-0078 will be revised to incorporate those clarifications.
    ANA requested that a cable assembly with a different lock wire 
length (part number BACC13AT3K()) be allowed for use in place of part 
number BACCI3AT3Kl2 for the actions specified in paragraph (g) of the 
proposed AD. ANA also identified an error in Boeing Special Attention 
Service Bulletin 777-28-0078, dated September 4, 2014, regarding the 
position of the connector D11007P.
    We do not agree with the commenters' requests. We have determined 
that Boeing Special Attention Service Bulletin 777-28-0078, Revision 1, 
dated April 27, 2015, is adequate to correct the identified unsafe 
condition, and the errors will not affect compliance with this AD. The 
information notices (IN) are issued to provide clarity and are not 
required to accomplish the required actions. We are working with Boeing 
to include the IN information and part number substitution and other 
corrections in Revision 2 of Boeing Service Bulletin 777-28-0078. Under 
the provisions of paragraph (k) of this AD, once Revision 2 of Boeing 
Service Bulletin 777-28-0078 is issued, we will consider requests to 
approve it as an alternative method of compliance (AMOC) with this AD. 
In addition, AMOCs for part number substitutions can also be requested 
through the provisions of paragraph (k) of this AD. We have not changed 
this AD in this regard.

Request To Address an Integer Overflow Error

    An anonymous commenter stated that Model 777 airplanes have an 
integer overflow error when being operated over a certain number of 
days. The commenter stated that we should require the computer to be 
reset before any of the overflow errors happen during flight.
    We do not agree with the commenter's request. This issue does not 
appear related to the identified unsafe condition that is the subject 
of this final rule. However, we will investigate this situation to make 
sure that the issue stated by the commenter does not exist or is 
addressed in a proper manner. We have not changed this final rule 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:
     [Agr]re 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.

    We have received no definitive data that will enable us to provide 
cost estimates for the on-condition actions specified in this AD.
    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.
