We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 777-200, -200LR, -300, and -300ER series airplanes. This proposed AD was prompted by reports of corrosion in the aft fuselage. This proposed AD would require a one-time review of the operator's maintenance procedures, repetitive detailed internal and external inspections for corrosion or cracking, and applicable on- condition actions. This proposed AD would also include an optional terminating action for the inspections. We are proposing this AD to address the unsafe condition on these products.

in the aft fuselage. This proposed AD would require a one-time review 
of the operator's maintenance procedures, repetitive detailed internal 
and external inspections for corrosion or cracking, and applicable on-
condition actions. This proposed AD would also include an optional 
terminating action for the inspections. We are proposing this AD to 
address the unsafe condition on these products.

Discussion

    We have received reports indicating extensive corrosion was found 
in the lower left side of the aft fuselage, between station 1790 and 
station 2033.5, from stringer S-34L to stringer S-49R. On several 
airplanes, additional corrosion was found after initial repairs were 
made to adjacent areas. This corrosion was caused by a failure to fully 
clean and neutralize spills or leaks of acidic or corrosive contents 
from the vacuum waste system. Vacuum waste system residue on the 
structure or in insulation blankets becomes reactivated with moisture 
that develops during flight, causing additional corrosion. Untreated 
spills can allow the breakdown of protective finishes and accelerate 
the corrosion reaction rate. This condition, if not corrected, could 
cause fatigue cracks, which could result in rapid decompression and 
loss of structural integrity.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Alert Service Bulletin 777-53A0083, dated April 
20, 2017. The service information describes procedures for a one-time 
review of the operator's maintenance procedures, repetitive detailed 
internal and external inspections for corrosion or cracking, cleaning 
and neutralization of the internal inspection area (an optional 
terminating action), and applicable on-condition actions. 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 require accomplishment of the actions 
identified as ``RC'' (required for compliance) in the Accomplishment 
Instructions of Boeing Alert Service Bulletin 777-53A0083, dated April 
20, 2017, described previously, except for any differences identified 
as exceptions in the regulatory text of this proposed AD.
    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-2017-0630.

Costs of Compliance

    We estimate that this proposed AD affects 161 airplanes of U.S. 
registry. The cost to review an operator's maintenance program varies 
depending on the operator's recordkeeping system and fleet size. We 
estimate the following costs to comply with the remaining actions of 
this proposed AD:

                                                                     Estimated Costs

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

    Except as required by paragraph (h) of this AD: At the 
applicable times specified in paragraph 1.E., ``Compliance,'' of 
Boeing Alert Service Bulletin 777-53A0083, dated April 20, 2017, do 
all applicable actions identified as ``RC'' (required for 
compliance) in, and in accordance with, the Accomplishment 
Instructions of Boeing Alert Service Bulletin 777-53A0083, dated 
April 20, 2017.

(h) Exceptions to Service Information Specifications

    (1) Where Boeing Alert Service Bulletin 777-53A0083, dated April 
20, 2017, uses the phrase ``after the original issue date of this 
service bulletin,'' for purposes of determining compliance with the 
requirements of this AD, the phrase ``after the effective date of 
this AD'' must be used.
    (2) Where Boeing Alert Service Bulletin 777-53A0083, dated April 
20, 2017, specifies contacting Boeing, and specifies that action as 
RC: This AD requires using a method approved in accordance with the 
procedures specified in paragraph (j) of this AD.

(i) Optional Terminating Action for Repetitive Inspections

    Accomplishment of ``PART 5: CLEANING AND NEUTRALIZATION,'' as 
specified in the Accomplishment Instructions of Boeing Alert Service 
Bulletin 777-53A0083, dated April 20, 2017, terminates the 
repetitive inspections required by paragraph (g) of this AD.

(j) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Seattle Aircraft Certification Office (ACO), 
FAA, has the authority to approve AMOCs for this AD, if requested 
using the procedures found in 14 CFR 39.19. In accordance with 14 
CFR 39.19, send your request to your principal inspector or local 
Flight Standards District Office, as appropriate. If sending 
information directly to the manager of the ACO, send it to the 
attention of the person identified in paragraph (k)(1) of this AD. 
Information may be emailed to: [email protected].
    (2) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the local flight standards district office/certificate holding 
district office.
    (3) An AMOC that provides an acceptable level of safety may be 
used for any repair, modification, or alteration required by this AD 
if it is approved by the Boeing Commercial Airplanes Organization 
Designation Authorization (ODA) that has been authorized by the 
Manager, Seattle ACO, to make those findings. To be approved, the 
repair method, modification deviation, or alteration deviation must 
meet the certification basis of the airplane, and the approval must 
specifically refer to this AD.
    (4) Except as required by paragraph (h)(2) of this AD: For 
service information that contains steps that are labeled as RC, the 
provisions of paragraphs (j)(4)(i) and (j)(4)(ii) of this AD apply.
    (i) The steps labeled as RC, including substeps under an RC step 
and any figures identified in an RC step, must be done to comply 
with the AD. If a step or substep is

[[Page 32510]]

labeled ``RC Exempt,'' then the RC requirement is removed from that 
step or substep. An AMOC is required for any deviations to RC steps, 
including substeps and identified figures.
    (ii) Steps not labeled as RC may be deviated from using accepted 
methods in accordance with the operator's maintenance or inspection 
program without obtaining approval of an AMOC, provided the RC 
steps, including substeps and identified figures, can still be done 
as specified, and the airplane can be put back in an airworthy 
condition.
