(e) Unsafe Condition
This AD was prompted by reports of two
landing incidents where the alpha limiter
engaged in the landing flare in unstable air
while on the approach and caused high rate
of descent landings and damage to the
airplane. The FAA is issuing this AD to
address inappropriate alpha limiter
engagement during the landing flare, which
can limit pilot pitch authority during a
critical phase of flight near the ground, and
result in a high rate of descent landing with
possible consequent loss of control of the
airplane.
(f) Compliance
Comply with this AD within the
compliance times specified, unless already
done.
DEPARTMENT OF TRANSPORTATION
(1) The Manager, Atlanta ACO Branch,
FAA, has the authority to approve AMOCs

Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
The FAA proposes to adopt a
new airworthiness directive (AD) for all
The Boeing Company Model 747–100,
747–100B, 747–100B SUD, 747–200B,
747–200C, 747–200F, 747–300, 747–
400, 747–400D, 747–400F, 747SR, and
747SP series airplanes. This proposed
AD was prompted by reports that high
temperature composite trim air diffuser
ducts (TADD) showed composite
degradation and signs of hot air leakage.
This proposed AD would require a onetime low frequency eddy current (LFEC)
inspection of certain center tank upper
skin panels on the right and left side for
any structural damage due to heat
exposure, and repair if necessary. The
FAA is proposing this AD to address the
unsafe condition on these products.
DATES: The FAA must receive comments
on this proposed AD by October 24,
2022.
ADDRESSES: You may send comments,
using the procedures found in 14 CFR
11.43 and 11.45, by any of the following
methods:

2022–00204–T’’ at the beginning of your hot air leakage from damaged TADDs
could result in undetected damage to
adjacent airframe structure. This
condition, if not addressed, could lead
to heat damage to the wing center
section and adjacent structure and
adversely affect the structural integrity
of the airplane, resulting in the inability
of the structure to carry limit load and
the possible loss of continued safe flight
and landing.
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 747–57A2370
RB, dated March 2, 2022. This service
information specifies procedures for a
one-time LFEC inspection for any
structural damage due to heat exposure
of the center tank upper skin panels on
the right and left side between station
(STA) 1100–1120, 1140–1160, and
1180–1200 bays outboard of left buttock
line (LBL) 98 and right buttock line
(RBL) 98 seat tracks, and repair.
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 regulations.gov by
searching for and locating Docket No.
FAA–2022–1059.
Costs of Compliance
The FAA estimates that this AD, if
adopted as proposed, would affect 104
airplanes of U.S. registry. The FAA
estimates the following costs to comply
with this proposed AD:

Federal Register / Vol. 87, No. 173 / Thursday, September 8, 2022 / Proposed Rules
The FAA has received no definitive
data on which to base the cost estimates
for the on-condition repairs specified in
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.
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.

Background
The FAA has received a report of multiple failures of the high
temperature composite material TADDs, which showed composite
degradation and signs of hot air leakage. Sustained hot air leakage
from damaged TADDs could result in undetected damage to adjacent
airframe structure. This condition, if not addressed, could lead to
heat damage to the wing center section and adjacent structure and
adversely affect the structural integrity of the airplane, resulting in
the inability of the structure to carry limit load and the possible
loss of continued safe flight and landing.
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 747-57A2370 RB,

The FAA has received no definitive data on which to base the cost
estimates for the on-condition repairs specified in 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.
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.
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-2022-1059; Project Identifier AD-
2022-00204-T.
(a) Comments Due Date
The FAA must receive comments on this airworthiness directive
(AD) by October 24, 2022.
(b) Affected ADs
None.
(c) Applicability
This AD applies to all The Boeing Company Model 747-100, 747-
100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747-400,
747-400D, 747-400F, 747SR, and 747SP series airplanes, certificated
in any category.
(d) Subject
Air Transport Association (ATA) of America Code 57, Wings.
(e) Unsafe Condition
This AD was prompted by reports that high temperature composite
trim air diffuser ducts (TADD) showed composite degradation and
signs of hot air leakage. The FAA is issuing this AD to address
sustained hot air leakage from damaged TADDs that could result in
undetected damage to adjacent airframe structure. This condition, if
not addressed, could lead to heat damage to the wing center section
and adjacent structure and adversely affect the structural integrity
of the airplane, resulting in the inability of the structure to
carry limit load and the possible loss of continued safe flight and
landing.
(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 747-57A2370 RB, dated March 2, 2022, do
all applicable actions identified in, and in accordance with, the
Accomplishment Instructions of Boeing Alert Requirements Bulletin
747-57A2370 RB, dated March 2, 2022.
Note 1 to paragraph (g): Guidance for accomplishing the actions
required by this AD can be found in Boeing Alert Service Bulletin
747-57A2370, dated March 2, 2022, which is referred to in Boeing
Alert Requirements Bulletin 747-57A2370 RB, dated March 2, 2022.
(h) Exceptions to Service Information Specifications
(1) Where the Compliance Time column of the table in the
``Compliance'' paragraph of Boeing Alert Requirements Bulletin 747-
57A2370 RB, dated March 2, 2022, uses the phrase ``the original
issue date of Requirements Bulletin 747-57A2370 RB,'' this AD
requires using ``the effective date of this AD.''
(2) Where Boeing Alert Requirements Bulletin 747-57A2370 RB,
dated March 2, 2022, specifies contacting Boeing for repair
instructions: This AD requires doing the repair before further
flight using a method approved in accordance with the procedures
specified in paragraph (i) of this AD.
(i) 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
identified in paragraph (j)(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 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.
