Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2019-01-
08, which applied to certain The Boeing Company Model 777-200, -200LR, 
-300, and -300ER series airplanes. AD 2019-01-08 required modifications 
for galley mounted attendant seat fittings. This AD was prompted by a 
report that showed a non-compliance exists on some in-service galley 
attendant seat fitting installations, and a determination that 
additional airplanes are subject to the unsafe condition. This AD 
requires modifications for galley mounted attendant seat fittings. The 
FAA is

DATES: This AD is effective January 19, 2022.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of January 19, 
2022.

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2019-01-08, Amendment 39-19547 (84 FR 4318, 
February 15, 2019) (AD 2019-01-08). AD 2019-01-08 applied to certain 
The Boeing Company Model 777-200, -200LR, -300, and -300ER series 
airplanes. The NPRM published in the Federal Register on June 25, 2021 
(86 FR 33574). The NPRM was prompted by a report that showed a non-
compliance exists on some in-service galley attendant seat fitting 
installations, and a determination that additional airplanes are 
subject to the unsafe condition. In the NPRM, the FAA proposed to 
continue to require modifications for galley mounted attendant seat 
fittings and expand the applicability to include additional airplanes. 
The FAA is issuing this AD to address non-compliant flight attendant 
seats, which could fail in a high-G crash and result in potential 
injury to flight attendants and consequent inability of the flight 
attendants to assist with passenger evacuation in a timely manner.

Discussion of Final Airworthiness Directive

Comments

    The FAA received comments from Boeing and United Airlines, who 
supported the NPRM without change.

Conclusion

    The FAA reviewed the relevant data, considered any comments 
received, and determined that air safety requires adopting this AD as 
proposed. Except for minor editorial changes, this AD is adopted as 
proposed in the NPRM. None of the changes will increase the economic 
burden on any operator.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Boeing Special Attention Service Bulletin 777-25-
0649, Revision 2, dated October 8, 2020. This service information 
specifies procedures for modifying galley mounted attendant seat 
fittings. 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.

Costs of Compliance

    The FAA estimates that this AD affects 50 airplanes of U.S. 
registry. The FAA estimates 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.
    The FAA is 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) Will not affect intrastate aviation in Alaska, and
    (3) 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.

effective date of this AD.''

(i) No Reporting Requirement

    Although the service information referenced in Boeing Special 
Attention Service Bulletin 777-25-0649, Revision 2, dated October 8, 
2020, specifies to submit certain information to the manufacturer, 
this AD does not include that requirement.

(j) Credit for Previous Actions

    This paragraph provides credit for the actions specified in 
paragraph (g) of this AD, if those actions were performed before the 
effective date of this AD using Boeing Special Attention Service 
Bulletin 777-25-0649, Revision 1, dated October 6, 2017 (which is 
incorporated by reference in AD 2019-01-08).

(k) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Seattle ACO Branch, 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 responsible Flight Standards Office, 
as appropriate. If sending information directly to the manager of 
the certification office, send it to the attention of the person 
identified in Related Information. 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 responsible Flight Standards 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 Company Organization Designation 
Authorization (ODA) that has been authorized by the Manager, Seattle 
ACO Branch, FAA, 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) AMOCs approved for AD 2019-01-08 are approved as AMOCs for 
the corresponding provisions of Boeing Special Attention Service 
Bulletin 777-25-0649, Revision 2, dated October 8, 2020, that are 
required by paragraph (g) of this AD.
    (5) For service information that contains steps that are labeled 
as Required for Compliance (RC), the provisions of paragraphs 
(k)(5)(i) and (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 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.
