Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for all The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This proposed AD was prompted by a report indicating that foreign object debris (FOD) could have been introduced during rework of certain engine fire shutoff switches (EFSS). This proposed AD would require determining the serial number of the left and right EFSS and replacing affected parts. This proposed AD would also limit the installation of affected parts under certain conditions. The FAA is proposing this AD to address the unsafe condition on these products.

receives that 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 FOD could have been
introduced in the left or right EFSS having certain serial numbers
during rework at a sub-tier supplier. The affected EFSS are part of the
engine fire control panel part number (P/N) 412600-003, with left EFSS
P/N 417000-104 and right EFSS P/N 417000-105. FOD in an EFSS, if not
addressed, could result in a latent failure and loss of intended
functions, including the inability to pull the engine fire handle and
uncommanded activation of the engine fuel shutoff function. The
inability to pull the engine fire handle when an engine fire is
detected could lead to an uncontrolled engine fire and subsequent wing
failure, and uncommanded activation of the fuel shutoff function for an
engine, which if combined with in-flight shutdown of the remaining
engine, could lead to total loss of engine thrust. Boeing and the parts
supplier have notified operators who received affected EFSS parts and
asked operators to return the parts for inspection and rework to
address the unsafe condition. Any affected EFSS that has undergone this
inspection and rework has been marked with ``Inspection Record SB
[[Page 40748]]
D533-1X-003,'' and is acceptable for installation on an airplane.
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 B787-81205-
SB260010-00 RB, Issue 001, dated May 2, 2022. This service information
specifies procedures for determining the serial number of the left EFSS
having P/N 417000-104 and the right EFSS having P/N 417000-105, and
replacing any EFSS having an affected serial number with an EFSS that
does not have an affected serial number, or with an EFSS that has an
affected serial number but is marked with ``Inspection Record SB D533-
1X-003.''
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 as discussed under
``Differences Between this Proposed AD and the Service Information''
and except for any differences identified as exceptions in the
regulatory text of this proposed AD. This proposed AD would also limit
the installation of affected parts under certain conditions. For
information on the procedures and compliance times, see this service
information at <a href="https://www.regulations.gov">https://www.regulations.gov</a> by searching for and
locating Docket No. FAA-2022-0799.
Other Relevant Rulemaking
The FAA issued AD 2021-02-06, Amendment 39-21389 (86 FR 10790,
February 23, 2021) (AD 2021-02-06) to address a latent failure of the
engine fire handle. AD 2021-02-06 requires, among other actions,
replacing engine fire control panel part number (P/N) 412600-001 with
P/N 412600-003, or modifying P/N 412600-001 and re-identifying it as P/
N 412600-003. Engine fire control panel part number P/N 412600-003
includes left EFSS P/N 417000-104 and right EFSS P/N 417000-105, which
are the EFSS this proposed AD would require inspecting and replacing if
necessary. AD 2021-02-06 has a compliance time of within 15 months
after March 30, 2021, for operators to install or modify the engine
fire control panel, including the right and left EFSS.
Differences Between This Proposed AD and the Service Information
The effectivity of Boeing Alert Requirements Bulletin B787-81205-
SB260010-00 RB, Issue 001, dated May 2, 2022, is limited to Model 787
airplanes having certain line numbers. However, the applicability of
this proposed AD includes all Boeing Model 787 airplanes. Because the
affected EFSS are rotable parts, the FAA has determined that these
parts could later be installed on airplanes that were initially
delivered with acceptable EFSS, thereby subjecting those airplanes to
the unsafe condition. The FAA has confirmed that the Accomplishment
Instructions in Boeing Alert Requirements Bulletin B787-81205-SB260010-
00 RB, Issue 001, dated May 2, 2022, are applicable to the expanded
group of airplanes.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 132 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
----------------------------------------------------------------------------------------------------------------
Determination of EFSS serial number... 1 work-hour x $85 per $0 $85 $11,220
hour = $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
----------------------------------------------------------------------------------------------------------------
Action Labor cost Parts cost Cost per product
----------------------------------------------------------------------------------------------------------------
Replacement of EFSS..................... 2 work-hours x $85 per $9,685 $9,855
hour = $170. (for one EFSS).
----------------------------------------------------------------------------------------------------------------
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.
[[Page 40749]]
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.
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 adding the following new airworthiness
directive:
The Boeing Company: Docket No. FAA-2022-0799; Project Identifier AD-
2022-00611-T.
(a) Comments Due Date
The FAA must receive comments on this airworthiness directive
(AD) by August 22, 2022.
(b) Affected ADs
None.
(c) Applicability
This AD applies to all The Boeing Company Model 787-8, 787-9,
and 787-10 airplanes, certificated in any category.
(d) Subject
Air Transport Association (ATA) of America Code 26, Fire
protection.
(e) Unsafe Condition
This AD was prompted by a report indicating that foreign object
debris (FOD) could have been introduced during rework of certain
engine fire shutoff switches (EFSS). The FAA is issuing this AD to
address FOD in an EFSS, which if not addressed, could result in a
latent failure and loss of intended functions, including the
inability to pull the engine fire handle and uncommanded activation
of the engine fuel shutoff function. The inability to pull the
engine fire handle when an engine fire is detected could lead to an
uncontrolled engine fire and subsequent wing failure and uncommanded
activation of the fuel shutoff function for an engine, which if
combined with in-flight shutdown of the remaining engine, could lead
to total loss of engine thrust.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Required Actions
For airplanes with an original airworthiness certificate or
original export certificate of airworthiness issued on or before the
effective date of this AD: Except as specified by paragraph (h) of
this AD, at the applicable time specified in the ``Compliance''
paragraph of Boeing Alert Requirements Bulletin B787-81205-SB260010-
00 RB, Issue 001, dated May 2, 2022, do all applicable actions
identified in, and in accordance with, the Accomplishment
Instructions of Boeing Alert Requirements Bulletin B787-81205-
SB260010-00 RB, Issue 001, dated May 2, 2022.
Note 1 to paragraph (g): Guidance for accomplishing the actions
required by this AD can be found in Boeing Alert Service Bulletin
B787-81205-SB260010-00, Issue 001, dated May 2, 2022, which is
referred to in Boeing Alert Requirements Bulletin B787-81205-
SB260010-00 RB, Issue 001, dated May 2, 2022.
(h) Exceptions to Service Information Specifications
Where the Compliance Time column of the table in the
``Compliance'' paragraph of Boeing Alert Requirements Bulletin B787-
81205-SB260010-00 RB, Issue 001, dated May 2, 2022, uses the phrase
``the Issue 001 date of Requirements Bulletin B787-81205-SB260010-00
RB,'' this AD requires using ``the effective date of this AD.''
(i) Parts Installation Limitation
For airplanes with an original airworthiness certificate or
original export certificate of airworthiness issued after the
effective date of this AD: As of the effective date of this AD, no
person may install a left EFSS P/N 417000-104 or a right EFSS P/N
417000-105, having a serial number specified in Boeing Alert
Requirements Bulletin B787-81205-SB260010-00 RB, Issue 001, dated
May 2, 2022, unless that EFSS is marked with ``Inspection Record SB
D533-1X-003.''
