Airworthiness Directives; The Boeing Company Model 777-200, -300,
and -300ER 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 installing an auto shutoff
feature for the center override/jettison fuel pumps, and installing
power control circuitry for the center override/jettison and main
jettison fuel pumps. This AD also requires installing new software in
the electrical load management system (ELMS) electronics units in
certain power management panels; installing airplane information
management system 2 (AIMS-2) software in the AIMS-2 hardware; and
making certain wiring changes. This AD was prompted by results from
fuel system reviews conducted by the manufacturer. We are issuing this
AD to prevent potential ignition sources inside fuel tanks, which, in
combination with flammable fuel vapors, could result in a fuel tank
explosion and consequent loss of the airplane.
DATES: This AD is effective May 26, 2011.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of May 26, 2011.

SUPPLEMENTARY INFORMATION:
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 30, 2010 (75 FR 82337). That NPRM proposed to require
installing an auto shutoff feature for the center override/jettison
fuel pumps, and installing power control circuitry for the center
override/jettison and main jettison fuel pumps. That NPRM also proposed
to require installing new software in the electrical load management
system (ELMS) electronics units in certain power management panels;
installing airplane information management system 2 (AIMS-2) software
in the AIMS-2 hardware; and making certain wiring changes.
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. Boeing supports the NPRM.
Request To Delay Issuance of AD To Specify Spring Washers Instead of
Conical Springs
Japan Airlines (JAL) requested that we delay issuance of the AD
until GE Aviation Service Bulletins 5000ELM-28-456 and 6000ELM-28-457,
both Revision 1, both dated January 7, 2010, are revised to correct
Figure 8. JAL stated that Figure 8 shows conical springs rather than
spring washers in the diagram. JAL stated that without this change,
operators will be required to request an alternate method of compliance
(AMOC).
We disagree with delaying issuance of this AD. However, we agree
that clarification is needed in regard to the use of spring washers.
Certain airplanes may use spring washers in lieu of conical springs in
their relay assembly. Both the conical springs and spring washers are
retained from the existing relay assembly to be used with the new
relay. Either one of them is considered acceptable for use. New
paragraph (m) has been added to the AD to identify the use of spring
washers as an acceptable method of compliance if they are part of the
existing relay assembly.
Request To Delay Issuance of AD To Specify Label Installation
JAL requested that we delay the issuance of this AD until GE
Aviation publishes new revisions to their service information
(referenced in the NPRM) to add another procedure to install labels or
separate the labels from the conversion kit. JAL explained that when it
receives the labels as part of the conversion kit, the remaining shelf
life of the labels is not adequate to allow the labels to be installed
on the airplanes. JAL is concerned that, unless the service information
is revised, these issues could delay incorporation of this AD or result
in multiple AMOC requests.
We disagree with the request to delay this AD until GE Aviation
issues revised service information. However, we agree with JAL's
concerns about the shelf life of the labels possibly affecting
operators' ability to comply with this AD within the required
compliance times. This AD requires all actions, including labeling, in
the Accomplishment Instructions of GE Aviation Service Bulletins
5000ELM-28-456 and 6000ELM-28-457, both Revision 1, both dated January
7, 2010, to be accomplished. We have added paragraph (n) to this AD to
provide an optional method of labeling.
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. We have determined that
these 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 the AD.
Costs of Compliance
We estimate that this AD affects 2 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:

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.
