14 CFR Part 39
[Docket No. FAA-2019-0974; Product Identifier 2019-NM-155-AD]
RIN 2120-AA64
Airworthiness Directives; The Boeing Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD)
2017-15-01, which applies to certain The Boeing Company Model 777
airplanes. AD 2017-15-01 requires replacing the existing mode control
panel (MCP) with a new MCP having a different part number. Since we
issued AD 2017-15-01, the FAA has determined that the affected parts
may be installed on airplanes outside of the original applicability of
AD 2017-15-01. This proposed AD would 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 proposing this AD to
[[Page 68061]]
address the unsafe condition on these products.

Discussion
The FAA issued AD 2017-15-01, Amendment 39-18961 (82 FR 33782, July
21, 2017) (``AD 2017-15-01''), for certain The Boeing Company Model 777
airplanes. AD 2017-15-01 requires replacing the existing MCP with a new
MCP having a different part number. AD 2017-15-01 resulted from reports
of uncommanded altitude display changes in the MCP altitude window. The
FAA issued AD 2017-15-01 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.
Actions Since AD 2017-15-01 Was Issued
Since AD 2017-15-01 was issued, it has been determined that the
affected parts may be installed as rotable spares on airplanes outside
of the applicability of AD 2017-15-01, thereby subjecting those
airplanes to the unsafe condition. Therefore, the applicability in this
proposed AD has been expanded to include all The Boeing Company Model
777 airplanes. In addition, the FAA has determined that the
installation of later-approved parts is acceptable for the replacement
that would be required by this proposed AD.
Related Service Information Under 1 CFR Part 51
This proposed AD would require 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.
FAA's Determination
The FAA is 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 2017-
15-01, and would expand the applicability to include all The Boeing
Company Model 777 airplanes. This proposed AD would also require an
inspection or records check to identify the part number of the affected
parts, and for airplanes with affected parts, accomplishing the actions
specified in the service information described previously, except as
discussed under ``Differences Between this Proposed AD and the Service
Information.'' For information on the procedures, see this service
information at https://www.regulations.gov by searching for and
locating Docket No. FAA-2019-0974.
Differences Between This Proposed AD and the Service Information
The effectivity of Boeing Special Attention Service Bulletin 777-
22-0034, dated March 3, 2016, is limited to certain The Boeing Company
Model 777 airplanes. However, the applicability of this proposed AD
includes all The Boeing Company Model 777 airplanes. Because the
affected parts are rotable parts, the FAA has determined that these
parts could later be installed on airplanes that were initially
delivered with acceptable parts, thereby subjecting those airplanes to
the unsafe condition. This difference has been coordinated with Boeing.
Boeing Special Attention Service Bulletin 777-22-0034, dated March
3, 2016, limits the replacement part to an MCP having part number
S241W001-262. This proposed AD would allow the installation of later-
approved parts for the replacement, provided those later-approved parts
meet certain conditions.
Costs of Compliance
The FAA estimates that this proposed AD affects 231 airplanes of
U.S. registry. The FAA estimates the following costs to comply with
this proposed AD:
[[Page 68062]]

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.
This proposed AD is issued in accordance with authority delegated
by the Executive Director, Aircraft Certification Service, as
authorized by FAA Order 8000.51C. In accordance with that order,
issuance of ADs is normally a function of the Compliance and
Airworthiness Division, but during this transition period, the
Executive Director has delegated the authority to issue ADs applicable
to transport category airplanes and associated appliances to the
Director of the System Oversight Division.
Regulatory Findings
The FAA has 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) 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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.

conclusively determined from that review.
(2) If the MCP is an affected part, within 60 months after the
effective date of this AD:
[[Page 68063]]
Do the actions specified in paragraph (i)(2)(i) or (ii) of this AD.
(i) Replace the existing MCP with an MCP having part number
S241W001-262, in accordance with the Accomplishment Instructions of
Boeing Special Attention Service Bulletin 777-22-0034, dated March
3, 2016.
(ii) Install a later-approved part as defined in paragraph
(g)(2) of this AD.
(j) Parts Installation Prohibition
As of the effective date of this AD, no person may install an
MCP having part number S241W001-201, S241W001-202, S241W001-251,
S241W001-252, or S241W001-261, on any airplane.
(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)(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 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.
