Federal Register Abstract
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.

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
--------------------------------------------------------------------------------------------------------------------------------------------------------
Action Labor cost Parts cost Cost per product Cost on U.S. operators
--------------------------------------------------------------------------------------------------------------------------------------------------------
Replacement......................... 2 work-hours x $85 per Up to $5,800 *............. Up to $5,970 *............. Up to $1,379,070 *.

Inspection/records check (new 1 work-hour x $85 per $0......................... $85........................ Up to $2,380.
proposed action) (up to 28 hour = $85.
airplanes).
--------------------------------------------------------------------------------------------------------------------------------------------------------
* 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.

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.
