Under the Freedom of Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public disclosure. If your comments responsive to this NPRM contain commercial or financial information that is customarily treated as private, that you actually treat as private, and that is relevant or responsive to this NPRM, it is important that you clearly designate the submitted comments as CBI. Please mark each page of your submission containing CBI as ‘‘PROPIN.’’ The FAA will treat such marked submissions as confidential under the FOIA, and they will not be placed in the public docket of this NPRM. Submissions containing CBI should be sent to Jeffrey Palmer, Aerospace Engineer, Systems and Equipment Section, FAA, Los Angeles ACO Branch, 3960 Paramount Boulevard, Lakewood, CA 90712–4137; phone: 562–627–5351; fax: 562–627– 5210; email: jeffrey.w.palmer@faa.gov. Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background The FAA has received a report indicating that an operator of a 747–8 airplane reported an in-flight event in which the captain’s primary flight display (PFD) and navigation display (ND) flickered after an involuntary autopilot disconnect, followed by the blanking of the main EICAS display unit. EICAS information was displayed on the lower EICAS display unit for the remainder of the flight. Multiple EICAS messages and unusual checklists appeared intermittently. The crew observed a master caution light and beeper as these messages appeared and disappeared. The over speed/stall red dots were displayed all along the captain’s speed tape; however, there was no over speed aural alert or stick shaker. The flightcrew declared PAN– PAN (urgent situation) due to unusual flight instrument and EICAS behavior E:\FR\FM\15NOP1.SGM 15NOP1 62961 Federal Register / Vol. 86, No. 217 / Monday, November 15, 2021 / Proposed Rules and the airplane landed safely. The root cause of this incident was found to be a hardware problem in the EIU, specifically the input/output (I/O) chip on the affected Aeronautical Radio, Incorporated (ARINC), I/O card. Handbrushed application of the conformal coating led to an excess of the conformal coating migrating underneath the I/O chip. This resulted in an interconnect problem between the I/O chip and the ARINC I/O card. This condition, if not addressed, could result in reduced ability of the flightcrew to maintain continued safe flight and landing of the aircraft. FAA’s Determination The FAA is issuing this NPRM after determining that the unsafe condition described previously is likely to exist or develop on other products of the same type design. Proposed AD Requirements in This NPRM Related Service Information Under 1 CFR Part 51 This proposed AD would require accomplishing the actions specified in the service information already described, except for any differences identified as exceptions in the regulatory text of this proposed AD. For information on the procedures and compliance times, see this service information at https:// www.regulations.gov by searching for and locating Docket No. FAA–2021– 0957. The FAA reviewed Boeing Alert Requirements Bulletin 747–31A2565 RB, Revision 1, dated September 14, 2021. This service information specifies procedures for doing an inspection or a review of the maintenance and delivery records of the left, center, and right EIUs for any affected serial number, and replacing each affected EIU. 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 ADDRESSES. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 8 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost Inspection ................................ 1 work-hour × $85 per hour = $85 ......................................... The FAA estimates the following costs to do any necessary replacements that would be required based on the Cost per product Parts cost results of the proposed inspection. The agency has no way of determining the $0 Cost on U.S. operators $85 $680 number of aircraft that might need these replacements: khammond on DSKJM1Z7X2PROD with PROPOSALS ON-CONDITION COSTS Action Labor cost Parts cost Replacement ............................ Up to 3 work-hours × $85 per hour = Up to $255 .................... Up to $9,600 ............. Cost per product Up to $9,855. Authority for This Rulemaking Regulatory Findings The Proposed Amendment 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. The FAA 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 this proposed regulation: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, (2) Would not affect intrastate aviation in Alaska, and (3) Would not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: VerDate Sep<11>2014 17:19 Nov 12, 2021 Jkt 256001 List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain The Boeing Company Model 747-8F and 747-8 series airplanes. 
This proposed AD was prompted by a report of unusual flight instrument 
and engine indication and crew alerting system (EICAS) behavior. This 
proposed AD would require inspecting the left, center, and right

    The FAA invites you to send any written relevant data, views, or 
arguments about this proposal. Send your comments to an address listed 
under ADDRESSES. Include ``Docket No. FAA-2021-0957; Project Identifier 
AD-2021-00469-T'' at the beginning of your comments. The most helpful 
comments reference a specific portion of the proposal, explain the 
reason for any recommended change, and include supporting data. The FAA 
will consider all comments received by the closing date and may amend 
this proposal because of those comments.
    Except for Confidential Business Information (CBI) as described in 
the following paragraph, and other information as described in 14 CFR 
11.35, the FAA will post all comments received, without change, to 
https://www.regulations.gov, including any personal information you 
provide. The agency will also post a report summarizing each 
substantive verbal contact received about this NPRM.

Confidential Business Information

    CBI is commercial or financial information that is both customarily 
and actually treated as private by its owner. Under the Freedom of 
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public 
disclosure. If your comments responsive to this NPRM contain commercial 
or financial information that is customarily treated as private, that 
you actually treat as private, and that is relevant or responsive to 
this NPRM, it is important that you clearly designate the submitted 
comments as CBI. Please mark each page of your submission containing 
CBI as ``PROPIN.'' The FAA will treat such marked submissions as 
confidential under the FOIA, and they will not be placed in the public 
docket of this NPRM. Submissions containing CBI should be sent to 
Jeffrey Palmer, Aerospace Engineer, Systems and Equipment Section, FAA, 
Los Angeles ACO Branch, 3960 Paramount Boulevard, Lakewood, CA 90712-
4137; phone: 562-627-5351; fax: 562-627-5210; email: 
[email protected]. Any commentary that the FAA receives which is 
not specifically designated as CBI will be placed in the public docket 
for this rulemaking.

Background

    The FAA has received a report indicating that an operator of a 747-
8 airplane reported an in-flight event in which the captain's primary 
flight display (PFD) and navigation display (ND) flickered after an 
involuntary autopilot disconnect, followed by the blanking of the main 
EICAS display unit. EICAS information was displayed on the lower EICAS 
display unit for the remainder of the flight. Multiple EICAS messages 
and unusual checklists appeared intermittently. The crew observed a 
master caution light and beeper as these messages appeared and 
disappeared. The over speed/stall red dots were displayed all along the 
captain's speed tape; however, there was no over speed aural alert or 
stick shaker. The flightcrew declared PAN-PAN (urgent situation) due to 
unusual flight instrument and EICAS behavior

[[Page 62961]]

and the airplane landed safely. The root cause of this incident was 
found to be a hardware problem in the EIU, specifically the input/
output (I/O) chip on the affected Aeronautical Radio, Incorporated 
(ARINC), I/O card. Hand-brushed application of the conformal coating 
led to an excess of the conformal coating migrating underneath the I/O 
chip. This resulted in an interconnect problem between the I/O chip and 
the ARINC I/O card. This condition, if not addressed, could result in 
reduced ability of the flightcrew to maintain continued safe flight and 
landing of the aircraft.

FAA's Determination

    The FAA is issuing this NPRM after determining that the unsafe 
condition described previously is likely to exist or develop on other 
products of the same type design.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Boeing Alert Requirements Bulletin 747-31A2565 RB, 
Revision 1, dated September 14, 2021. This service information 
specifies procedures for doing an inspection or a review of the 
maintenance and delivery records of the left, center, and right EIUs 
for any affected serial number, and replacing each affected EIU.
    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 ADDRESSES.

Proposed AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified 
in the service information already described, except for any 
differences identified as exceptions in the regulatory text of this 
proposed AD. For information on the procedures and compliance times, 
see this service information at https://www.regulations.gov by 
searching for and locating Docket No. FAA-2021-0957.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 8 airplanes of U.S. registry. The FAA estimates the following 
costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
               Action                         Labor cost            Parts cost        product        operators

Inspection.........................  1 work-hour x $85 per hour               $0             $85            $680
                                      = $85.
----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary 
replacements that would be required based on the results of the 
proposed inspection. The agency has no way of determining the number of 
aircraft that might need these replacements:

                                               On-Condition Costs

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 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 this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

September 14, 2021.

(d) Subject

    Air Transport Association (ATA) of America Code 31, Instruments.

(e) Unsafe Condition

    This AD was prompted by a report of unusual flight instrument 
and engine indication and crew alerting system (EICAS) behavior. The 
FAA is issuing this AD to address the possible display of incorrect 
information in the integrated display system (IDS). This condition, 
if not addressed, could result in reduced ability of the flightcrew 
to maintain continued safe flight and landing of the aircraft.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Required Actions

    Except as specified by paragraph (h) of this AD: At the 
applicable times specified in the ``Compliance'' paragraph of Boeing 
Alert Requirements Bulletin 747-31A2565 RB, Revision 1, dated 
September 14, 2021, do all applicable actions identified in, and in 
accordance with, the Accomplishment Instructions of Boeing Alert 
Requirements Bulletin 747-31A2565 RB, Revision 1, dated September 
14, 2021.
    Note 1 to paragraph (g): Guidance for accomplishing the actions 
required by this AD can be found in Boeing Alert Service Bulletin 
747-31A2565, Revision 1, dated September 14, 2021, which is referred 
to in Boeing Alert Requirements Bulletin 747-31A2565 RB, Revision 1, 
dated September 14, 2021.

(h) Exception to Service Information Specifications

    Where Boeing Alert Requirements Bulletin 747-31A2565 RB, 
Revision 1, dated September 14, 2021, uses the phrase ``the Original 
Issue date of Requirements Bulletin 747-31A2565 RB,'' this AD 
requires using ``the effective date of this AD.''

(i) 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 Alert Requirements Bulletin 
747-31A2565 RB, dated April 27, 2021.

(j) 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

    (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.
