Discussion The FAA has examined the underlying safety issues involved in fuel tank explosions on several large transport airplanes, including the adequacy of existing regulations, the service history of airplanes subject to those regulations, and existing maintenance practices for fuel tank systems. As a result of those findings, we issued a regulation titled ‘‘Transport Airplane Fuel Tank System Design Review, Flammability Reduction and Maintenance and Inspection Requirements’’ (66 FR 23086, May 7, 2001). In addition to new airworthiness standards for transport airplanes and new maintenance requirements, this rule included Special Federal Aviation Regulation No. 88 (‘‘SFAR 88,’’ Amendment 21–78, and subsequent Amendments 21–82 and 21–83). Among other actions, SFAR 88 requires certain type design (i.e., type certificate (TC) and supplemental type certificate (STC)) holders to substantiate that their fuel tank systems can prevent ignition sources in the fuel tanks. This PO 00000 Frm 00022 Fmt 4702 Sfmt 4702 requirement applies to type design holders for large turbine-powered transport airplanes and for subsequent modifications to those airplanes. It requires them to perform design reviews and to develop design changes and maintenance procedures if their designs do not meet the new fuel tank safety standards. As explained in the preamble to the rule, we intended to adopt airworthiness directives to mandate any changes found necessary to address unsafe conditions identified as a result of these reviews. In evaluating these design reviews, we have established four criteria intended to define the unsafe conditions associated with fuel tank systems that require corrective actions. The percentage of operating time during which fuel tanks are exposed to flammable conditions is one of these criteria. The other three criteria address the failure types under evaluation: Single failures, single failures in combination with a latent condition(s), and in-service failure experience. For all four criteria, the evaluations included consideration of previous actions taken that may mitigate the need for further action. We have determined that the actions identified in this AD are necessary to reduce the potential of 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. Results of a safety assessment revealed that there is a small risk of an ignition source in a fuel tank if a center override/jettison fuel pump or a main jettison fuel pump continues to run when there is no fuel at the pump inlet, or when the pumps are commanded to stop running (commanded off) and they remain on. When a pump runs after the fuel level goes below the pump inlet, there is a small risk that the pump can cause an ignition source in the fuel tank from an overheat condition, electrical arcs, or frictional sparks. This condition, if not corrected, could result in a fuel tank explosion and consequent loss of the airplane. Relevant Service Information We reviewed Boeing Service Bulletin 777–28A0047, Revision 5, dated September 20, 2010. That service information describes procedures for installing a new P301 panel on the left side of the airplane, installing a new P302 panel on the right side of the airplane, and changing the wiring; and performing certain bonding resistance measurements and reworking the airplane installation to verify that E:\FR\FM\30DEP1.SGM 30DEP1 82339 Federal Register / Vol. 75, No. 250 / Thursday, December 30, 2010 / Proposed Rules certain bonding requirements are met if necessary. Boeing Service Bulletin 777– 28A0047, Revision 5, dated September 20, 2010, specifies prior or concurrent accomplishment of the following service bulletins: • Boeing Service Bulletin 777– 28A0040, Revision 1, dated March 18, 2010, which describes procedures for installing new software in the ELMS electronics units in the P110, P210, and P310 power management panels. • Boeing Special Attention Service Bulletin 777–31–0097, Revision 3, dated February 22, 2007, which describes procedures for installing AIMS–2 software in the AIMS–2 hardware. • GE Aviation Service Bulletin 5000ELM–28–456, Revision 1, dated January 7, 2010, which describes procedures for changing the wiring of the ELMS P110 left power management panel. • GE Aviation Service Bulletin 6000ELM–28–457, Revision 1, dated January 7, 2010, which describes procedures for changing the wiring of the ELMS P210 right power management panel. FAA’s Determination We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of these same type designs. Proposed AD Requirements This proposed AD would require accomplishing the actions specified in the service information described previously, except as discussed under ‘‘Differences Between the Proposed AD and the Service Information.’’ Differences Between the Proposed AD and the Service Information Boeing Special Attention Service Bulletin 777–31–0097, Revision 3, dated February 22, 2007, specifies a compliance time of 60 months. This AD requires a 36-month compliance time to install the AIMS–2 software upgrade. This difference has been coordinated with the manufacturer.

and -300ER Series Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the 
products listed above. This proposed AD would require installing an 
auto shutoff feature for the center override/jettison fuel pumps, and 
installing power control circuitry for the center

also 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. This 
proposed AD was prompted by results from fuel system reviews conducted 
by the manufacturer. We are proposing this AD to prevent the potential 
of 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: We must receive comments on this proposed AD by February 14, 
2011.

Discussion

    The FAA has examined the underlying safety issues involved in fuel 
tank explosions on several large transport airplanes, including the 
adequacy of existing regulations, the service history of airplanes 
subject to those regulations, and existing maintenance practices for 
fuel tank systems. As a result of those findings, we issued a 
regulation titled ``Transport Airplane Fuel Tank System Design Review, 
Flammability Reduction and Maintenance and Inspection Requirements'' 
(66 FR 23086, May 7, 2001). In addition to new airworthiness standards 
for transport airplanes and new maintenance requirements, this rule 
included Special Federal Aviation Regulation No. 88 (``SFAR 88,'' 
Amendment 21-78, and subsequent Amendments 21-82 and 21-83).
    Among other actions, SFAR 88 requires certain type design (i.e., 
type certificate (TC) and supplemental type certificate (STC)) holders 
to substantiate that their fuel tank systems can prevent ignition 
sources in the fuel tanks. This requirement applies to type design 
holders for large turbine-powered transport airplanes and for 
subsequent modifications to those airplanes. It requires them to 
perform design reviews and to develop design changes and maintenance 
procedures if their designs do not meet the new fuel tank safety 
standards. As explained in the preamble to the rule, we intended to 
adopt airworthiness directives to mandate any changes found necessary 
to address unsafe conditions identified as a result of these reviews.
    In evaluating these design reviews, we have established four 
criteria intended to define the unsafe conditions associated with fuel 
tank systems that require corrective actions. The percentage of 
operating time during which fuel tanks are exposed to flammable 
conditions is one of these criteria. The other three criteria address 
the failure types under evaluation: Single failures, single failures in 
combination with a latent condition(s), and in-service failure 
experience. For all four criteria, the evaluations included 
consideration of previous actions taken that may mitigate the need for 
further action.
    We have determined that the actions identified in this AD are 
necessary to reduce the potential of 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.
    Results of a safety assessment revealed that there is a small risk 
of an ignition source in a fuel tank if a center override/jettison fuel 
pump or a main jettison fuel pump continues to run when there is no 
fuel at the pump inlet, or when the pumps are commanded to stop running 
(commanded off) and they remain on. When a pump runs after the fuel 
level goes below the pump inlet, there is a small risk that the pump 
can cause an ignition source in the fuel tank from an overheat 
condition, electrical arcs, or frictional sparks. This condition, if 
not corrected, could result in a fuel tank explosion and consequent 
loss of the airplane.

Relevant Service Information

    We reviewed Boeing Service Bulletin 777-28A0047, Revision 5, dated 
September 20, 2010. That service information describes procedures for 
installing a new P301 panel on the left side of the airplane, 
installing a new P302 panel on the right side of the airplane, and 
changing the wiring; and performing certain bonding resistance 
measurements and reworking the airplane installation to verify that

[[Page 82339]]

certain bonding requirements are met if necessary.
    Boeing Service Bulletin 777-28A0047, Revision 5, dated September 
20, 2010, specifies prior or concurrent accomplishment of the following 
service bulletins:
     Boeing Service Bulletin 777-28A0040, Revision 1, dated 
March 18, 2010, which describes procedures for installing new software 
in the ELMS electronics units in the P110, P210, and P310 power 
management panels.
     Boeing Special Attention Service Bulletin 777-31-0097, 
Revision 3, dated February 22, 2007, which describes procedures for 
installing AIMS-2 software in the AIMS-2 hardware.
     GE Aviation Service Bulletin 5000ELM-28-456, Revision 1, 
dated January 7, 2010, which describes procedures for changing the 
wiring of the ELMS P110 left power management panel.
     GE Aviation Service Bulletin 6000ELM-28-457, Revision 1, 
dated January 7, 2010, which describes procedures for changing the 
wiring of the ELMS P210 right power management panel.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of these same type 
designs.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in the service information described previously, except as discussed 
under ``Differences Between the Proposed AD and the Service 
Information.''

Differences Between the Proposed AD and the Service Information

    Boeing Special Attention Service Bulletin 777-31-0097, Revision 3, 
dated February 22, 2007, specifies a compliance time of 60 months. This 
AD requires a 36-month compliance time to install the AIMS-2 software 
upgrade. This difference has been coordinated with the manufacturer.

Costs of Compliance

    We estimate that this proposed AD will affect 2 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs

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

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under the 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.
