Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2017-15-
01, which applied to certain The Boeing Company Model 777 airplanes. AD 
2017-15-01 required replacing the existing mode control panel (MCP) 
with a new MCP having a different part number. This AD retains the 
requirements of AD 2017-15-01, expands the applicability to include 
certain other airplanes, and adds a new requirement for certain 
airplanes to identify and replace the affected parts. This AD was 
prompted by a determination that the affected parts may be installed on 
airplanes outside of the original applicability of AD 2017-15-01. The 
FAA is issuing this AD to address the unsafe condition on these 
products.

DATES: This AD is effective April 21, 2020.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of August 25, 
2017 (82 FR 33782, July 21, 2017).

SUPPLEMENTARY INFORMATION: 

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2017-15-01, Amendment 39-18961 (82 FR 
33782, July 21, 2017) (``AD 2017-15-01''). AD 2017-15-01 applied to 
certain The Boeing Company Model 777 airplanes. The NPRM published in 
the Federal Register on December 13, 2019 (84 FR 68060). The NPRM was 
prompted by a determination that the affected parts may be installed on 
airplanes outside of the original applicability of AD 2017-15-01. The 
NPRM proposed to retain the requirements of AD 2017-15-01, expand the 
applicability to include those other airplanes, and add a new 
requirement for certain airplanes to identify and replace the affected 
parts. The FAA is issuing this AD to address uncommanded changes to the 
MCP selected altitude; such uncommanded changes could result in 
incorrect spatial separation between airplanes, midair collision, or 
controlled flight into terrain.

Comments

    The FAA gave the public the opportunity to participate in 
developing this AD. The FAA has considered the comments received. The 
Air Line Pilots Association, International (ALPA) and Boeing indicated 
their support for the NPRM. United Airlines and FedEx had no objection 
to the NPRM.

Conclusion

    The FAA reviewed the relevant data, considered the comments 
received, and determined that air safety and the public interest 
require adopting this AD as proposed, except for minor editorial 
changes. The FAA has determined that these minor changes:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    This AD requires Boeing Special Attention Service Bulletin 777-22-
0034, dated March 3, 2016, which the Director of the Federal Register 
approved for incorporation by reference as of August 25, 2017 (82 FR 
33782, July 21, 2017). 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 231 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                                                     Estimated Costs

* Since the FAA has received no definitive data regarding the cost of a new MCP, the FAA has provided costs for the upgrade (modified part) only.

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

    The FAA has determined that 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.

unless already done.

(g) New Definitions

    (1) For the purposes of this AD, an affected part is an MCP 
having part number S241W001-201, S241W001-202, S241W001-251, 
S241W001-252, or S241W001-261.
    (2) For the purposes of this AD, later-approved parts are only 
those parts that are approved as a replacement for the applicable 
part identified in Boeing Special Attention Service Bulletin 777-22-
0034, dated March 3, 2016; and are approved as part of the type 
design by the FAA or The Boeing Company Organization Designation 
Authorization (ODA) after March 3, 2016 (the publication date of 
Boeing Special Attention Service Bulletin 777-22-0034, dated March 
3, 2016).

(h) Retained Replacement of MCP With Revised Compliance Language

    This paragraph restates the requirements of AD 2017-15-01, with 
revised compliance language. For airplanes identified in Boeing 
Special Attention Service Bulletin 777-22-0034, dated March 3, 2016, 
within 60 months after August 25, 2017, (the effective date of AD 
2017-15-01): Do the actions specified in paragraph (h)(1) or (2) of 
this AD.
    (1) Replace the existing MCP part with an MCP having part number 
S241W001-262, in accordance with the Accomplishment Instructions of

(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 local Flight Standards District 
Office, as appropriate. If sending information directly to the 
manager of the certification office, send it to the attention of the 
person identified in paragraph (l) 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 Company 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 previously for AD 2017-15-01 are approved as 
AMOCs for the corresponding provisions 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.
