Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2011-26-
03, which applies to certain The Boeing Company Model 777-200, -200LR, 
-300, and -300ER series airplanes. AD 2011-26-03 currently requires 
installing Teflon sleeving under the clamps of certain wire bundles 
routed along the fuel tank boundary structure, and cap sealing certain 
penetrating fasteners of the main and center fuel tanks. AD 2011-26-03 
resulted from fuel system reviews conducted by the manufacturer. Since 
we issued AD 2011-26-03, we have received a report indicating that 
additional airplanes are affected by the identified unsafe condition. 
This proposed AD would add airplanes to the applicability. This AD 
would also add, for certain airplanes, detailed inspections of certain 
wire bundle clamps, certain Teflon sleeves, and certain fasteners; 
corrective actions if necessary; and installation of Teflon sleeves 
under certain wire bundle clamps. We are proposing this AD to prevent 
electrical arcing on the fuel tank boundary structure or inside the 
fuel tanks, which could result in a fire or explosion.

DATES: We must receive comments on this proposed AD by September 6, 
2016.

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. Subsequently, SFAR 88 was amended by: Amendment 21-82 
(67 FR 57490, September 10, 2002; corrected at 67 FR 70809, November 
26, 2002) and Amendment 21-83 (67 FR 72830, December 9, 2002; corrected 
at 68 FR 37735, June 25, 2003, to change ``21-82'' to ``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, combination of 
failures, and unacceptable (failure) experience. For all three failure 
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 proposed AD 
are necessary to reduce the potential of ignition sources inside fuel 
tanks, which, in combination with flammable fuel vapors, could result 
in fuel tank explosions and consequent loss of the airplane.
    On December 5, 2011, we issued AD 2011-26-03, Amendment 39-16893 
(76 FR 78138, December 16, 2011) (``AD 2011-26-03''), for certain The 
Boeing Company Model 777-200, -200LR, -300, and -300ER series 
airplanes. AD 2011-26-03 requires installing Teflon sleeving under the 
clamps of certain wire bundles routed along the fuel tank boundary 
structure, and cap sealing certain penetrating fasteners of the main 
and center fuel tanks. AD 2011-26-03 resulted from fuel system reviews 
conducted by the manufacturer. We issued AD 2011-26-03 to prevent 
electrical arcing on the fuel tank boundary structure or inside the 
fuel tanks, which could result in a fire or explosion.

Actions Since AD 2011-26-03 Was Issued

    Since we issued AD 2011-26-03, we have received a report indicating 
that additional airplanes are affected by the identified unsafe 
condition.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Service Bulletin 777-57A0050, Revision 4, dated 
September 28, 2015. The service information describes procedures for 
installing Teflon sleeving under the clamps of certain wire bundles 
routed along the fuel tank boundary structure, and cap sealing certain 
penetrating fasteners of the main and center fuel tanks; as well as 
detailed inspections of certain wire bundle clamps, certain Teflon 
sleeves, and certain fasteners; corrective actions if necessary; and 
installation of Teflon sleeves under certain wire bundle clamps. 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.

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 the same type design.

Proposed AD Requirements

    This proposed AD would retain all of the requirements of AD 2011-
26-03. This proposed AD would also revise the applicability by adding 
Boeing Model 777-200LR and 777F series airplanes. This proposed AD 
would also require accomplishing the actions specified in the service 
information described previously, except as described in ``Differences 
Between this Proposed AD and the Service Information''. For information 
on the procedures and compliance times, see this service information at 
http://www.regulations.gov by searching for and locating Docket No. 
FAA-2016-8179.
    The phrase ``corrective actions'' is used in this proposed AD. 
``Corrective actions'' correct or address any condition found. 
Corrective actions in an AD could include, for example, repairs.

Differences Between This Proposed AD and the Service Information

    Boeing has issued Alternative Method of Compliance (AMOC) Notice 
777-57A0050 AMOC 02, dated February 15, 2016, to provide the correct 
group applicability for ``WORK PACKAGE 21: More Work: Rear Spar Wire 
Bundle Teflon sleeve Installation,'' Figure 3, and Figure 100 of Boeing 
Service Bulletin 777-57A0050, Revision 4, dated September 28, 2015. We 
have included these changes in paragraphs (k)(1), (k)(2), and (k)(3) of 
this AD.

Costs of Compliance

    We estimate that this proposed AD affects 182 airplanes of U.S. 
registry. We estimate the following costs to comply with this proposed 
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

    We have 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 that the 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.
