SUPPLEMENTARY INFORMATION: 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 laterapproved parts is acceptable for the replacement that would be required by this proposed AD. Comments Invited The FAA invites you to send any written relevant data, views, or VerDate Sep<11>2014 16:11 Dec 12, 2019 Jkt 250001 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. 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 PO 00000 Frm 00002 Fmt 4702 Sfmt 4702 68061 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 laterapproved 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: E:\FR\FM\13DEP1.SGM 13DEP1 68062 Federal Register / Vol. 84, No. 240 / Friday, December 13, 2019 / Proposed Rules ESTIMATED COSTS Action Labor cost Parts cost Cost per product Cost on U.S. operators Replacement (retained actions from AD 2017-15-01). Inspection/records check (new proposed action) (up to 28 airplanes). 2 work-hours × $85 per hour = $170. 1 work-hour × $85 per hour = $85. Up to $5,800 * ............... Up to $5,970 * ............... Up to $1,379,070.* $0 .................................. $85 ................................ Up to $2,380. * 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. jbell on DSKJLSW7X2PROD with PROPOSALS 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 VerDate Sep<11>2014 16:11 Dec 12, 2019 Jkt 250001 (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 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by removing Airworthiness Directive (AD) 2017–15–01, Amendment 39–18961 (82 FR 33782, July 21, 2017), and adding the following new AD: ■ The Boeing Company: Docket No. FAA– 2019–0974; Product Identifier 2019– NM–155–AD. (a) Comments Due Date The FAA must receive comments on this AD action by January 27, 2020. (b) Affected ADs This AD replaces AD 2017–15–01, Amendment 39–18961 (82 FR 33782, July 21, 2017) (‘‘AD 2017–15–01’’). (c) Applicability This AD applies to all The Boeing Company Model 777–200, –200LR, –300, –300ER, and 777F series airplanes, certificated in any category. (d) Subject Air Transport Association (ATA) of America Code 22, Auto flight. (e) Unsafe Condition This AD was prompted by reports of uncommanded altitude display changes in the mode control panel (MCP) altitude window. The FAA is issuing this AD to address uncommanded changes to the MCP selected altitude; such uncommanded PO 00000 Frm 00003 Fmt 4702 Sfmt 4702 changes could result in incorrect spatial separation between airplanes, midair collision, or controlled flight into terrain. (f) Compliance Comply with this AD within the compliance times specified, 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, laterapproved 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.

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

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:

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.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by removing Airworthiness Directive (AD) 
2017-15-01, Amendment 39-18961 (82 FR 33782, July 21, 2017), and adding 
the following new AD:

The Boeing Company: Docket No. FAA-2019-0974; Product Identifier 
2019-NM-155-AD.

(a) Comments Due Date

    The FAA must receive comments on this AD action by January 27,

(e) Unsafe Condition

    This AD was prompted by reports of uncommanded altitude display 
changes in the mode control panel (MCP) altitude window. 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.

(f) Compliance

    Comply with this AD within the compliance times specified, 
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 
Boeing Special Attention Service Bulletin 777-22-0034, dated March 
3, 2016.
    (2) Install a later-approved part as defined in paragraph (g)(2) 
of this AD.

(i) New MCP Identification and Replacement

    For airplanes not identified in paragraph (h) of this AD with an 
original airworthiness certificate or original export certificate of 
airworthiness issued on or before the effective date of this AD, do 
the actions specified in paragraphs (i)(1) and (2) of this AD.
    (1) Within 60 months after the effective date of this AD, 
perform a general visual inspection of the MCP to determine the MCP 
part number. A review of airplane maintenance records is acceptable 
in lieu of this inspection if the part number of the MCP can be 
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.
