Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2022-09-
18, which applied to all The Boeing Company Model 707, 717, and 727
airplanes; Model DC-8, DC-9, and DC-10 airplanes; Model MD-10 and MD-11
airplanes; Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), DC-
9-87 (MD-87), and MD-88 airplanes; and Model MD 90-30 airplanes. AD
2022-09-18 required revising the limitations and operating procedures
sections of the existing airplane flight manual (AFM) to incorporate
specific operating procedures for, depending on the airplane model,
instrument landing system (ILS) approaches, non-precision approaches,
ground spoiler deployment, and go-around and missed approaches, when in
the presence of interference from wireless broadband operations in the
3.7-3.98 GHz frequency band (5G C-Band) as identified by Notices to Air
Missions (NOTAMs). Since the FAA issued AD 2022-09-18, the FAA
determined that additional limitations are needed due to the continued
deployment of new 5G C-Band stations whose signals are expected to
cover most of the contiguous United States at transmission frequencies
between 3.7-3.98 GHz. This AD requires revising the limitations and
operating procedures

sections of the AFM to incorporate specific operating procedures for,
depending on the airplane model, ILS approaches, non-precision
approaches, ground spoiler deployment, and go-around and missed
approaches, due to the presence of 5G C-Band interference. The FAA is
issuing this AD to address the unsafe condition on these products.

DATES: This AD is effective June 21, 2023.

ADDRESSES: AD Docket: You may examine the AD docket at regulations.gov
under Docket No. FAA-2023-0923; or in person at Docket Operations
between 9 a.m. and 5 p.m., Monday through Friday, except Federal

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede AD 2022-09-18, Amendment 39-22038 (87 FR
31097, May 23, 2022) (AD 2022-09-18). AD 2022-09-18 applied to all The
Boeing Company (Boeing) Model 707, 717, and 727 airplanes; Model DC-8,
DC-9, and DC-10 airplanes; Model MD-10 and MD-11 airplanes; Model DC-9-
81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), DC-9-87 (MD-87), and MD-
88 airplanes; and Model MD 90-30 airplanes. The NPRM published in the
Federal Register on May 3, 2023 (88 FR 27749). The NPRM was prompted by
a determination that radio altimeters cannot be relied upon to perform
their intended function if they experience 5G C-Band interference, and
a determination that during approach, landings, and go-arounds, as a
result of this interference, certain airplane systems may not properly
function, resulting in increased flightcrew workload while on approach
with the flight director, autothrottle, or autopilot engaged.
    In the NPRM, the FAA proposed to retain the AFM revisions required
by AD 2022-09-18 until June 30, 2023. On or before June 30, 2023, the
FAA proposed to require replacing those AFM revisions with limitations
requiring the same procedures for, depending on the airplane model, ILS
approaches, non-precision approaches, ground spoiler deployment, and
go-around and missed approaches, at all airports for non-radio
altimeter tolerant airplanes. For radio altimeter tolerant airplanes,
the FAA proposed that the procedures would not be required at 5G C-Band
mitigated airports (5G CMAs) as identified in an FAA Domestic Notice.
The FAA proposed this AD to address 5G C-Band interference that could
result in increased flightcrew workload and could lead to reduced
ability of the flightcrew to maintain safe flight and landing of the
airplane.

Discussion of Final Airworthiness Directive

Comments

    The FAA provided the public with an opportunity to comment on the
proposed AD and received comments from three commenters. The following
presents the comments received on the NPRM and the FAA's response to
each comment.

Support for NPRM

    Boeing and the Air Line Pilots Association, International (ALPA),
supported the NPRM without change.
    The supportive comments from ALPA included additional viewpoints
without a suggestion specific to the AD or a request the FAA can act
on. These comments are outside the scope of this final rule.

Request To Extend Compliance Time

    Comment summary: American Airlines expressed concern regarding the
compliance time for the proposed actions and requested the FAA revise
the AD to provide a minimum of 30 days from the effective date of the
AD.
    FAA response: The FAA understands the commenter's concern and made
every effort to publish this AD as soon as possible. After refraining
from operating at their FCC-authorized levels for a year and a half,
wireless companies are now able to operate at higher levels, yet still
not at the levels authorized. Specifically, wireless companies expect
to operate their networks in urban areas with minimal restrictions due
to the completion of retrofits. Additionally, the FAA anticipates 19
additional telecommunication companies will begin transmitting in the
C-Band after June 30, 2023. Although the FAA continues to work with the
companies that intend to transmit in the 3.7-3.98-GHz band near 5G
CMAs, the FAA has no agreement with those companies to provide the FAA
with tower locations and other information necessary to support the
current NOTAM/AMOC process. Therefore, the FAA will not be able to
extend the June 30, 2023, date.

Conclusion

    The FAA reviewed the relevant data, considered any comments
received, and determined that air safety requires adopting this AD as
proposed. Accordingly, the FAA is issuing this AD to address the unsafe
condition on these products. This AD is adopted as proposed in the
NPRM.

Interim Action

    The FAA considers this AD to be an interim action. Once the
Technical Standard Order (TSO) standard for radio altimeters is
established, which will follow the existing international technical
consensus on the establishment of the minimum operational performance
standards (MOPS), the FAA anticipates that the MOPS will be
incorporated into the TSO. Once a new radio altimeter TSO is developed,
approved, and available, the FAA might consider additional rulemaking.

Effective Date

    Section 553(d) of the Administrative Procedure Act (APA) (5 U.S.C.
551 et seq.) requires publication of a rule not less than 30 days
before its effective date. However, section 553(d) authorizes agencies
to make rules effective in less than 30 days when the agency finds
``good cause.'' Radio altimeters cannot be relied upon to perform their
intended function if they experience interference from wireless
broadband operations in the 5G C-Band. This interference can cause
other airplane systems to not properly function, resulting in increased
flightcrew workload while on approach with the flight director,
autothrottle, or autopilot engaged. To address this unsafe condition,
the actions required by this AD must be accomplished before the
compliance date of June 30, 2023. The FAA based this date on the
changes to the 5G C-Band environment beginning on July 1, 2023. These
changes include increased wireless broadband deployment and
transmissions closer to the parameters authorized by the FCC. The
earlier operators learn of the requirements in this AD, the earlier
they can take action to ensure compliance. An effective date less than
30 days would ensure the AD is codified earlier, thereby increasing
awareness of its requirements. Therefore, the FAA finds that good cause
exists pursuant to 5 U.S.C. 553(d)

for making this amendment immediately effective.

Costs of Compliance

    The cost information below describes the costs to change the AFM.
Although this AD largely maintains the AFM limitations currently
required by AD 2022-09-18, the FAA acknowledges that this AD may also
impose costs on some aircraft operators from having to change their
conduct to comply with the amended AFM. However, the FAA lacks the data
necessary to quantify the costs associated with aircraft operators
changing their conduct.
    The FAA estimates that this AD affects 476 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                Cost per      Cost on U.S.
                Action                         Labor cost           Parts cost        product        operators
----------------------------------------------------------------------------------------------------------------
AFM revision (retained actions from AD  1 work-hour x $85 per                 $0             $85         $40,460
 2022-09-18).                            hour \1\ = $85.
New AFM revisions (new action)........  1 work-hour x $85 per                  0              85      \2\ 40,460
                                         hour = $85.
----------------------------------------------------------------------------------------------------------------
\1\ The labor rate of $85 per hour is the average wage rate for an aviation mechanic.
\2\ The estimated cost for this revision would not constitute a significant economic impact (even for small
  entities) because $85 is a minimal cost compared to the regular costs of maintaining and operating a 707, 717,
  727, DC-8, DC-9, DC-10, MD 10, MD-11, DC-9-81, DC-9-82, DC-9-83, DC-9-87, MD-88, or MD-90-30 transport
  category airplane.

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

    This AD will not have federalism implications under Executive Order
13132. This AD will 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 this AD:
    (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.

(e) Unsafe Condition

    This AD was prompted by a determination that radio altimeters
cannot be relied upon to perform their intended function if they
experience interference from wireless broadband operations in the
3.7-3.98 GHz frequency band (5G C-Band), and a determination that
during approach, landings, and go-arounds, as a result of this
interference, certain airplane systems may not properly function,
resulting in increased flightcrew workload while on approach with
the flight director, autothrottle, or autopilot engaged. The FAA is
issuing this AD to address 5G C-Band interference that could result
in increased flightcrew workload and could lead to reduced ability
of the flightcrew to maintain safe flight and landing of the
airplane.

(f) Compliance

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

(g) Definitions

    (1) For purposes of this AD, a ``5G C-Band mitigated airport''
(5G CMA) is an airport at

which the telecommunications companies have agreed to voluntarily
limit their 5G deployment at the request of the FAA, as identified
by an FAA Domestic Notice.
    (2) For purposes of this AD, a ``radio altimeter tolerant
airplane'' is one for which the radio altimeter, as installed,
demonstrates the tolerances specified in paragraphs (g)(2)(i) and
(ii) of this AD, using a method approved by the FAA.
    (i) Tolerance to radio altimeter interference, for the
fundamental emissions (3.7-3.98 GHz), at or above the power spectral
density (PSD) curve threshold specified in figure 1 to paragraph

	870.3700b Pre-natal Developmental Toxicity Study - Rabbit

Executive Summary: In a developmental toxicity study, New Zealand White
rabbits received V-53482 (94.8% purity) daily via gavage at doses of 0,
300, 1000, or 3000 mg/kg/day on gestational days (GDs) 7-19,
inclusively.  Group mean body weight gain (kg) during dosing (gestation
days 7-19) were as follows (0, 300, 1000 or 3000 mg/kg/day): 0.17, 0.18,
0.14 and 0.05 (p<0.05). Group mean food consumption (g/kg/day) during
dosing were as follows: 42.9, 42.1, 39.4 and 35.7 (p<0.05).  No other
parameters (maternal or developmental) were considered to have been
affected by test article administration.  Maternal LOAEL = 3000
mg/kg/day based on decreased body weight and food consumption mostly
during the dosing period Maternal NOAEL = 1000 mg/kg/day.  Developmental
LOAEL = not determined Developmental NOAEL = 3000 mg/kg/day  This study
is considered to be acceptable/guideline and meets the requirements to
fulfill 83-3 for a developmental toxicity study in rabbits.

A.3.3	Reproductive Toxicity

	870.3800 Reproduction and Fertility Effects - Rat

Executive Summary: In a two-generation reproduction study,
Sprague-Dawley rats were fed V-53482 (94.8% purity) in the diet at
dosage levels of 0, 50, 100, 200 or 300 ppm (during premating, at least
0, 3.2, 6.3, 12.7, and 18.9 mg/kg/day in males and 0, 3.8, 7.6, 15. 1,
and 22.7 mg/kg/day in females, respectively).  There were no definitive
clinical signs attributed to test article administration in males of
either generation. In F0 females only, there was an increase (p<0.01) in
the incidence of "red substance in vagina" only at 300 ppm (9/25 versus
0-1/27-30 for the other 4 groups).  The mortality in the F1 females was
as follows for 0, 50, 100, 200 or 300 ppm: 0, 1, 0, 0 and 5 (p<0.01).
Group mean body weight gains were less than control (p<0.05 or 0.01) in
F1 males and females during the first week of premating.  During
gestation, F0 and F1 females had lower body weight gain (p<0.01) during
the last 5 days and for the entire period of gestation(28-31% decrease
in gain).  There was a decrease in food consumption in 300 ppm females
of both generations: F0, 65-84% of control during lactation (p<0.05 or
0.01); F1, 92-95% of controls during gestation (p<0.05 or 0.01); and F1,
78-89% of control during lactation (p<0.05 or 0.01).  The incidence of
grossly observable yellow livers was increased in 300 ppm F1 females
that died (p<0.01, 3/30 versus 0/30 for controls). There was a decrease
(p<0.01) in absolute only testis and epididymides weights in 300 ppm F1
males (not F0). [Study authors excluded all rats with small organs from
the analysis.] No definitive histopathological changes were attributed
to test article administration.  There was the suggestion of
atrophied/hypoplastic/hypospermia of the testes and/or epididymides in
both generations of 300 ppm males (of 30 males examined in 0 and 300 ppm
groups, the treated group had no more than one finding more than the
control group).  Tissues from the 100 and 200 ppm (and most of the 50
ppm) groups were not evaluated.  In F1 300 ppm females that died, liver
lobular necrosis and bile stasis was observed (2-3/4 examined).
Systemic LOAEL = 300 ppm (mg/kg/day: males = 18.9, females = 22.7) based
on increased clinical signs (F0 females); increased mortality (Fl
females), gross and histopathology findings in the liver (Fl females);
decreased body weight/weight gain (F0 and Fl females during gestation,
Fl males during the early portion of premating); and decreased food
consumption (F0 and Fl females during lactation).  Systemic NOAEL = 200
ppm (mg/kg/day: males = 12.7, females = 15.1)  In both generations, the
following reproductive parameters were affected primarily at 300 ppm and
to a lesser extent at 200 ppm: females with liveborn (300 ppm, 16/21 for
Fl pups and 16/18 for F2 pups; control, 23/23 and 23/23); mean number of
live pups/litter on day one of lactation (300 ppm 7/9; control, 14/16);
mean pup weight on lactation day one (300 ppm, 5.7/5.6 g; 200 ppm,
6.1/6.1; control, 6.9/6.4).  Reproduction/Offspring LOAEL = 200 ppm
(mg/kg/day: males = 12.7, females = 15.1) based on decreased number of
females with liveborn and mean number of pups/litter on lactation day 1,
decreased pup body weight, testicular atrophy in F1 males and decreased
mating index.  Reproduction/Offspring NOAEL = 100 ppm (mg/kg/day: males
= 6.3, females = 7.6).  This study is classified acceptable/guideline
and meets the requirements of 83-4 for a two generation reproductive
toxicity study in rats.

A.3.4	Chronic Toxicity

	870.4100b Chronic Toxicity - Dog

A.3.5	Carcinogenicity

	870.4200a Carcinogenicity Study - rat

In a combined chronic/oncogenicity study (MRID 44295028), flumioxazin
(technical, 94.8% a.i., S-53482) was administered in the diet for up to
24 months to 74 Crj CD (SD) rats/sex/dose at levels of 0, 50, 500, and
1000 ppm (equivalent to 0, 1.8, 18.0, and 36.5 mg/kg/day in male rats
and 0, 2.2, 21.8, and 43.6 mg/kg/day in female rats).  At approximately
52 and 78 weeks 10-14 rats per group were terminated and all remaining
animals were terminated at approximately 104 weeks.  Survival rates,
clinical observations, clinical chemistry, ophthalmoscopic, urinalysis,
and gross pathologic parameters were unaffected by treatment with
S-53482.  Minor changes (2-15%) in hematological parameters (hemoglobin,
MCV, MCH, MCHC) in the midand high-dose females were consistent with a
chronic mild anemia.  The presence of circulating erythroblasts in
peripheral blood, reticulocytosis, decreased bone marrow
Myeloid/Erythroid ratio (949%, p<0.05) and splenic extramedullary
hematopoiesis (8/10 treated; 6/10 controls, p<0.05) are consistent with
a severe stress on erythropoiesis similar to what might be observed in
chronic iron deficiency.  However, the relatively moderate decreases in
hemoglobin and lack of progression to a more severe type of anemia such
as aplastic anemia or pancytopenia indicate successful compensatory
erythropoiesis.  Histopathological changes of the kidney indicative of
slight to mild chronic nephropathy was found at the final necropsy in
the 500 (18.0 mg/kg/day) and 1000 (36.5 mg/kg/dah) ppm male groups
(26-27/33 treated vs 13/31 controls, p<0.01).  The chronic LOAEL is 500
ppm (equivalent to 18.0 and 21.8 mg/kg/day in males and females,
respectively) based upon decreased hemoglobin, MCV, MCH and MCHC in
females and increased incidence of chronic nephropathy in males.  The
chronic NOAEL is 50 ppm (equivalent to 1.8 and 2.2 g/kg/day in males and
females, respectively).  Under the conditions of this study, there was
no evidence of carcinogenic potential.  Dosing was considered adequate
due to hematological and histopathological changes observed in the mid-
and high-dose animals.  This study is classified as acceptable (§83-5;
870.4300) and satisfies the guideline requirements for a combined
chronic toxicity study and a carcinogenicity study in rats.

	870.4200b Carcinogenicity (feeding) - Mouse

In a mouse oncogenicity study (MRID 44295018), flumioxazin technical,
94.8% a.i. (S-53482) was administered in the diet for 78 weeks to 51
CD-1 mice/sex/dose at levels of 0, 300, 3000 or 7000 ppm which is
equivalent to dietary levels of 0, 31.1, 314.9 or 754.1 mg/kg/day in
males and 0, 36.6, 346.4,or 859.1 mg/kg/day in females, respectively.
An additional 15 mice/sex/dose were used to provide samples for
hematological examination, pathology and histopathology.  These animals
were terminated at 53 weeks.  All remaining animals were sacrificed at
79 weeks of the study.  Survival rates, clinical observations, body
weights, feed consumption, organ weights, gross pathology and
hematological parameters were unaffected by treatment with S-53482.  No
clinical chemistry was performed.  There were statistically significant
increases in malignant lymphoma/leukemia in mid-dose males (6/15
treated; 1/14 controls, p<0.05) and increases in pulmonary adenoma in
mid-dose females (5/51 treated; 0/50 control, p<0.05), these tumor
incidences were comparable to historical controls and did not exhibit
dose-dependency.  The LOAEL was not observed.  The chronic NOAEL is >
7000 ppm which is equivalent to 754.1 and 859.1 mg/kg/day in male and
female mice, respectively.  Under the conditions of this study, there
was no evidence of carcinogenic potential.  Dosing was considered
adequate because the highest dose of 7000 ppm represented a "limit
dose".  This study is classified as acceptable (§83-2b; 870.4200) and
satisfies the guideline requirements for a carcinogenicity study in
mice.

	870.7485	Metabolism - Rat

EXECUTIVE SUMMARY: In a metabolism study, [phenyl-U-’4C)S-53482 was
administered to Sprague-Dawley rats (5/sex/dose) as a single oral dose
of 1 mg/kg or 100 mg/kg or as a single oral dose of 1 mg/kg following a
14-day pretreatment with unlabeled 5-53482 at 1 mg/kg/day. C.I. tract
absorption of S-53482 may amount to over 90% of the dose at 1 mg/kg and
to about 50% at 100 mg/kg.  Total recovery of radioactivity in feces and
urine, 7 days after dosing, accounted for 96.5- 100.7% of the dose in
all test groups.  Radioactivity excretion in urine was statistically
significantly elevated in females (38.8-42.8%, low dose; 22.9- 23.4%,
high dose) vs. males (28.1-30.8%, low dose; 12.8-13.0%, high dose).
Highest levels of residues were found in blood cells (35.9-48.8 ppb, low
dose and 2823-3040 ppb, high dose), which were much higher than the
plasma levels (0.5-0.7 ppb, low dose and 53-37 ppb, high dose).  TLC
analysis of feces and urine revealed up to 35 putative metabolites.  In
addition to untransformed parent compound, 7 metab, lites were
identified in urine and feces. Identified compounds amounted to
37.5-46.1% of the dose at the low dose treatments and to 70.7-71.5% of
the dose at the high dose.  The study is classified as CQre
Suptlem.ntar-y Data.  This study does not satisfy at present the
requirement, § 85-1 for metabolism study in rats.  However, this study
an be ungraded to Minimum if information (as detailed in p. 13 of the
DER) clarifying discrepancies between listed Rfs and apparent TLC
mobilities of standards, in addition to information on the type of TLC
used, is provided by the Registrant and is judged to be acceptable by
the Agency.

 In addition, the sum of material remaining in skin plus material
absorbed amounted to .2% of the dose at 10 hours and to 2.3% of the dose
at 24 hours.  At 1.0 mg/rat (0.02 mg/cm2), absorption ranged from 0.006%
of the dose at 0.5 hours to 0.47% at 24 hours.  In addition, the sum of
material remaining in skin plus material absorbed amounted to 1.4% of
the dose at 10 hours and to 2.4% of the dose at 24 hours.  The study is
classified as Core Minimum Data (Acceptable) and satisfies the
requirement (85-2) for a dermal absorption study in rats.

[Docket No. FAA-2013-0259-2245]

Agency Information Collection Activities: Requests for Comments;
Clearance of a Renewed Approval of Information Collection: FAA Aircraft
Noise Complaint and Inquiry System (Noise Portal)

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice and request for comments.

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

SUMMARY: In accordance with the Paperwork Reduction Act of 1995, FAA
invites public comments about our intention to request the Office of
Management and Budget (OMB) approval to renew an information
collection. The FAA Regional Administrators' Offices and the FAA Noise
Ombudsman will use the information voluntarily reported, on the
occasion of a complaint, by the public in the FAA Noise Portal to
prepare responses to their noise complaints or inquiries. The required
FAA Noise Portal fields represent the minimum amount of information the
FAA needs to address the public's noise complaint or question and
includes: name, email, address or cross street and a description of the
noise complaint or inquiry. It is important to know the person's name
and email address to respond and track the complaint. The FAA will not
respond to the same complaint from the same person more than once. The
address or cross street is needed for the FAA to determine potential
sources of the aircraft noise issues as most people complain about
aircraft in the vicinity of their residence. The description is used to
provide additional details for the FAA to better address the complaint
or question.

DATES: Written comments should be submitted by April 9, 2021.

ADDRESSES: Please send written comments:
    By Electronic Docket: www.regulations.gov (Enter docket number into
search field).
    By mail: Idurre L. Isasa-Cowan, Federal Aviation Administration,
AEE, 800 Independence Avenue SW, Suite 900W, Washington, DC 20591.

FOR FURTHER INFORMATION CONTACT: Idurre L. Isasa-Cowan, Email<EMAIL_ADDRESS>Phone:<PHONE_NUMBER>.

SUPPLEMENTARY INFORMATION:
    Public Comments Invited: You are asked to comment on any aspect of
this information collection, including (a) Whether the proposed
collection of information is necessary for FAA's performance; (b) the
accuracy of the estimated burden; (c) ways for FAA to enhance the
quality, utility and clarity of the information collection; and (d)
ways that the burden could be minimized without reducing the quality of
the collected information. The agency will summarize and/or include
your comments in the request for OMB's clearance of this information
collection.
    OMB Control Number: 2120-0773.
    Title: FAA Aircraft Noise Complaint and Inquiry System (Noise
Portal).
    Form Numbers: None.
    Type of Review: Renewal of an information collection.
    Background: Although the FAA already receives aircraft noise
complaints and inquiries from the public, the FAA's voluntary
collection of the information from the public invokes the PRA process.
The FAA must receive approval from the Office of Management and Budget
(OMB) to collect the information in the Noise Portal. The FAA will
summarize the public comments from the 60-day

comment period (March 1, 2021 to April 30, 2021), and address these in
a 30-day Federal Register notice inviting further comments. OMB has 60-
days from the date of the 30-day notice to approve the FAA's voluntary
collection of information in the Noise Portal. We expect the entire
process will be completed by July 2021.
    Respondents: The public.
    Frequency: As needed.
    Estimated Average Burden per Response: 15 minutes.
    Estimated Total Annual Burden: 11,250 hours.

    Issued in Washington, DC, on February 3, 2021.
