    Order No. 607 (64 FR 51222, September 22, 1999) requires Commission
decisional employees, who make or receive a prohibited or exempt off-
the-record communication relevant to the merits of a contested
proceeding, to deliver to the Secretary of the Commission, a copy of
the communication, if written, or a summary of the substance of any
oral communication.
    Prohibited communications are included in a public, non-decisional
file associated with, but not a part of, the decisional record of the
proceeding. Unless the Commission determines that the prohibited
communication and any responses thereto should become a part of the
decisional record, the prohibited off-the-record communication will not
be considered by the Commission in reaching its decision. Parties to a
proceeding may seek the opportunity to respond to any facts or
contentions made in a prohibited off-the-record communication, and may
request that the Commission place the prohibited communication and
responses thereto in the decisional record. The Commission will grant
such a request only when it determines that fairness so requires. Any
person identified below as having made a prohibited off-the-record
communication shall serve the document on all parties listed on the
official service list for the applicable proceeding in accordance with

Notice of Request To Release Airport Property for Land Disposal

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of request to rule on release of airport property for
land disposal at the Ottumwa Regional Airport (OTM), Ottumwa, Iowa.

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

SUMMARY: The FAA proposes to rule and invites public comment on the
release of land at the Ottumwa Regional Airport (OTM), Ottumwa, Iowa.

DATES: Comments must be received on or before February 22, 2022.

ADDRESSES: Comments on this application may be mailed or delivered to
the FAA at the following address: Amy J. Walter, Airports Land
Specialist, Federal Aviation Administration, Airports Division, ACE-
620G, 901 Locust, Room 364, Kansas City, MO 64106.
    In addition, one copy of any comments submitted to the FAA must be
mailed or delivered to: Zach Simonson, Community Development Director,
City of Ottumwa, 105 East Third Street, Ottumwa, Iowa 52501, (641) 683-
0694.

FOR FURTHER INFORMATION CONTACT: Amy J. Walter, Airports Land
Specialist, Federal Aviation Administration, Airports Division, ACE-
620G, 901 Locust, Room 364, Kansas City, MO 64106,<PHONE_NUMBER>,
[email protected]. The request to release property may be reviewed, by
appointment, in person at this same location.

SUPPLEMENTARY INFORMATION: The FAA invites public comment on the
request to release two tracts of land: Parcel 64 is 4.51 acres and
parcel 67 is 2.06 acres

of airport property at the Ottumwa Regional Airport (OTM) under the
provisions of 49 U.S.C. 47107(h)(2). Representatives of the Sponsor
requested a release from the FAA to sell two tracts of land, 4.51 acres
and 2.06 acres respectively. Both parcels will be developed for light
industrial use. The FAA determined the request to release property at
the Ottumwa Regional Airport (OTM) submitted by the Sponsor meets the
procedural requirements of the Federal Aviation Administration and the
release of the property does not and will not impact future aviation
needs at the airport. The FAA may approve the request, in whole or in
part, no sooner than thirty days after the publication of this notice.
    The following is a brief overview of the request:
    The Ottumwa Regional Airport (OTM) is proposing the release of two
airport parcels containing 4.51 acres and 2.06 acres. The release of
land is necessary to comply with Federal Aviation Administration Grant
Assurances that do not allow federally acquired airport property to be
used for non-aviation purposes. The sale of the subject property will
result in the land at the Ottumwa Regional Airport (OTM) being changed
from aeronautical to non-aeronautical use and release the lands from
the conditions of the Airport Improvement Program Grant Agreement Grant
Assurances in order to dispose of the land. In accordance with 49
U.S.C. 47107(c)(2)(B)(i) and (iii), the airport will receive fair
market value for the property, which will be subsequently reinvested in
another eligible airport improvement project for general aviation use.
    Any person may inspect, by appointment, the request in person at
the FAA office listed above under FOR FURTHER INFORMATION CONTACT. In
addition, any person may, upon appointment and request, inspect the
application, notice and other documents determined by the FAA to be
related to the application in person at the Ottumwa City Hall.

    Issued in Kansas City, MO, on January 18, 2022.

Director, FAA Central Region, Airports Division.

Consensus Standards, Light-Sport Aircraft

AGENCY: Federal Aviation Administration, DOT.

ACTION: Notice of availability; request for comments.

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

SUMMARY: This notice announces the availability of four revised
consensus standards to previously accepted consensus standards relating
to the provisions of the Sport Pilot and Light-Sport Aircraft rule
issued July 16, 2004, and effective September 1, 2004. ASTM
International Committee F37 on Light Sport Aircraft developed the
revised standards with Federal Aviation Administration (FAA)
participation. By this notice, the FAA finds the revised standards
acceptable for certification of

the specified aircraft under the provisions of the Sport Pilot and
Light-Sport Aircraft rule.

DATES: Comments must be received on or before December 14, 2009.

ADDRESSES: Comments may be mailed to: Federal Aviation Administration,
Small Airplane Directorate, Programs and Procedures Branch, ACE-114,
Attention: Terry Chasteen, Room 301, 901 Locust, Kansas City, Missouri
64106. Comments may also be e-mailed to: 9-ACE-AVR-LSA-
<EMAIL_ADDRESS>All comments must be marked: Consensus Standards
Comments, and must specify the standard being addressed by ASTM
designation and title.

FOR FURTHER INFORMATION CONTACT: Terry Chasteen, Light-Sport Aircraft
Program Manager, Programs and Procedures Branch (ACE-114), Small
Airplane Directorate, Aircraft Certification Service, Federal Aviation
Administration, 901 Locust, Room 301, Kansas City, Missouri 64106;
telephone<PHONE_NUMBER>; e-mail<EMAIL_ADDRESS>
SUPPLEMENTARY INFORMATION: This notice announces the availability of
four revised consensus standards to previously accepted consensus
standards relating to the provisions of the Sport Pilot and Light-Sport
Aircraft rule. ASTM International Committee F37 on Light Sport Aircraft
developed the new and revised standards. The FAA expects a suitable
consensus standard to be reviewed at least every two years. The two-
year review cycle will result in a standard revision or reapproval. A
standard is issued under a fixed designation (i.e., F2244); the number
immediately following the designation indicates the year of original
adoption or, in the case of revision, the year of last revision. A
number in parentheses indicates the year of last reapproval. A
reapproval indicates a two-year review cycle completed with no
technical changes. A superscript epsilon ([egr]) indicates an editorial
change since the last revision or reapproval. A notice of availability
(NOA) will only be issued for new or revised standards. Reapproved
standards issued with no technical changes or standards issued with
editorial changes only (i.e., superscript epsilon ([egr])) are
considered accepted by the FAA without need for a NOA.
    Comments Invited: Interested persons are invited to submit such
written data, views, or arguments, as they may desire. Communications
should identify the consensus standard number and be submitted to the
address specified above. All communications received on or before the
closing date for comments will be forwarded to ASTM International
Committee F37 for consideration. The standard may be changed in light
of the comments received. The FAA will address all comments received
during the recurring review of the consensus standard and will
participate in the consensus standard revision process.
    Background: Under the provisions of the Sport Pilot and Light-Sport
Aircraft rule, and revised Office of Management and Budget (OMB)
Circular A-119, ``Federal Participation in the Development and Use of
Voluntary Consensus Standards and in Conformity Assessment
Activities'', dated February 10, 1998, industry and the FAA have been
working with ASTM International to develop consensus standards for
light-sport aircraft. These consensus standards satisfy the FAA's goal
for airworthiness certification and a verifiable minimum safety level
for light-sport aircraft. Instead of developing airworthiness standards
through the rulemaking process, the FAA participates as a member of
Committee F37 in developing these standards. The use of the consensus
standard process assures government and industry discussion and
agreement on appropriate standards for the required level of safety.

Comments on Previous Notices of Availability

    In the Notice of Availability (NOA) issued on July 28, 2008, and
published in the Federal Register on July 28, 2008, the FAA asked for
public comments on the new and revised consensus standards accepted by
that NOA. The comment period closed on September 26, 2008. No public
comments were received regarding the standards accepted by this NOA.

Consensus Standards in This Notice of Availability

    The FAA has reviewed the standards presented in this NOA for
compliance with the regulatory requirements of the rule. Any light-
sport aircraft issued a special light-sport airworthiness certificate,
which has been designed, manufactured, operated and maintained, in
accordance with this and previously accepted ASTM consensus standards
provides the public with the appropriate level of safety established
under the regulations. Manufacturers who choose to produce these
aircraft and certificate these aircraft under 14 CFR part 21,
Sec. Sec.  21.190 or 21.191 are subject to the applicable consensus
standard requirements. The FAA maintains a listing of all accepted
standards on the FAA Web site.

The Revised Consensus Standard and Effective Period of Use

    The following previously accepted consensus standards have been
revised, and this NOA is accepting the later revision. Either the
previous revision or the later revision may be used for the initial
certification of special light-sport aircraft until April 1, 2010. This
overlapping period of time will allow aircraft that have started the
initial certification process using the previous revision level to
complete that process. After April 1, 2010, manufacturers must use the
later revision and must identify the later revision in the Statement of
Compliance for initial certification of special light-sport aircraft
unless the FAA publishes a specific notification otherwise. The
following Consensus Standard may not be used after April 1, 2010:
    ASTM Designation F2240-05, titled: Standard Specification for
Manufacturer Quality Assurance Program for Powered Parachute Aircraft.
    ASTM Designation F2244-05, titled: Standard Specification for
Design and Performance for Powered Parachute Aircraft.
    ASTM Designation F 2245-07a, titled: Standard Specification for
Design and Performance of a Light Sport Airplane.
    ASTM Designation F 2316-06, titled: Standard Specification for
Airframe Emergency Parachutes for Light Sport Aircraft.

The Consensus Standards

    The FAA finds the following revised consensus standards acceptable
for certification of the specified aircraft under the provisions of the
Sport Pilot and Light-Sport Aircraft rule. The consensus standards
listed below may be used unless the FAA publishes a specific
notification otherwise.
    a. ASTM Designation F2240-08, titled: Standard Specification for
Manufacturer Quality Assurance Program for Powered Parachute Aircraft.
    b. ASTM Designation F2244-08, titled: Standard Specification for
Design and Performance for Powered Parachute Aircraft.
    c. ASTM Designation F 2245-09, titled: Standard Specification for
Design and Performance of a Light Sport Airplane.

comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive about this proposed AD.

Discussion

    We were notified of broken or cracked welds in the connecting weld
of the muffler body to muffler cuff on certain Aerospace Welding
Minneapolis, Inc. (AWI) mufflers, part numbers (P/Ns) A1754001-23 and
A1754001-25 that were installed on Textron Aviation Inc. (type
certificate previously held by Cessna Aircraft Company) Models 172,
172R, 172S, and 177 airplanes. There have been 54 occurrences
identified by maintenance and 2 occurrences identified by the carbon
monoxide (CO) gas monitor warning system. This condition, if not
corrected, could lead to CO exhaust fumes entering the cockpit heating
system and result in inhibiting the pilot's ability to maintain control
of the airplane.

Related Service Information Under 1 CFR Part 51

    We reviewed AWI Cessna 172 (Lycoming) Muffler Removal and
Installation, Revision 01, January 17, 2017. The service information
describes procedures for removing and replacing the affected mufflers.
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.

Other Related Service Information

    We reviewed AWI Mandatory Service Bulletin No. 16063001, dated June
30, 2015. The service bulletin describes how to identify the
installation of an affected muffler.

FAA's Determination

    We are 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 require inspecting the muffler for leaking
to identify cracks and replacement of the muffler with an FAA-approved
part.

Differences Between This Proposed AD and the Service Information

    The AWI service bulletin requires replacement of the muffler before
further flight. This proposed AD would require an inspection of the
muffler for leaking to identify cracks within 5 hours time-in-service
(TIS) after the effective date of the AD with replacement of leaking
mufflers before further flight. This proposed AD would allow 100 hours
TIS or at the next annual inspection for replacement of non-leaking
mufflers. The service bulletin also requires returning the affected
mufflers back to AWI, and this proposed AD does not require return of
the muffler. The actions of the proposed AD would take precedence over
the service information.

Costs of Compliance

    We estimate that this proposed AD affects 171 mufflers installed on
airplanes of U.S. registry.
    We estimate 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 of muffler..........  1 work-hour x $85 per    Not applicable........             $85         $14,535
                                  hour = $85.
Replacement of the muffler.....  4 work-hours x $85 per   $350..................             690         117,990
                                  hour = $340.
----------------------------------------------------------------------------------------------------------------

    The proposed AD would affect 171 mufflers with parts manufacturer
approval; however, only 9 mufflers remain in service.
    According to the manufacturer, some of the costs of this proposed
AD may be covered under warranty, thereby reducing the cost impact on
affected individuals. We do not control warranty coverage for affected
individuals. As a result, we have included all costs in our cost
estimate.

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.
    We are 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

    We 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) Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) 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.

(d) Subject

    Joint Aircraft System Component (JASC)/Air Transport Association
(ATA) of America Code 7820, Exhaust Noise Suppressor.

(e) Unsafe Condition

    This AD was prompted by occurrences of cracks or broken welds in
the connecting weld of the muffler body to muffler cuff that may
allow carbon monoxide (CO) exhaust fumes into the cockpit heating
system. We are issuing this AD to prevent cracks in the connecting
weld of the muffler body to muffler cuff that may allow CO fumes to
enter the cockpit heating system and possibly inhibit the pilot's
ability to maintain control of the airplane.

(f) Compliance

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

(g) Inspection of the Muffler

    Within 5 hours time-in-service after the effective date of this
AD, inspect the affected muffler following the instructions listed
in paragraphs (g)(1) through (3).
    (1) Using a vacuum cleaner with the hose attached to the blowing
side of the vacuum (with the filter installed), attach the vacuum to
the airplane tailpipe and seal securely.
    (2) The vacuum will pressurize the system sufficiently for a
soap solution to be brushed or applied from a spray bottle to the
surface of the exhaust system.
    (3) Inspect for evidence of breaches (leakage) in the system
from cracks.
    (4) In lieu of doing this inspection and at the same within 5
hours after the effective date of this AD compliance time, you may
replace the affected muffler with an FAA-approved part that is not a
muffler listed in figure 1 of paragraph (c) of this AD.
    (i) This replacement must be done following AWI Cessna 172
(Lycoming) Muffler Removal and Installation, Revision 01, January
17, 2017.
    (ii) If replacement is done instead of the inspection, then
paragraph (h)(3) of this AD is the only additional requirement of
this AD.

(h) Replacement of the Muffler

    (1) If evidence of breaches (leakage) is found during the
inspection required in paragraph (g) of this AD, before further
flight, replace the affected muffler with an FAA-approved part
following AWI Cessna 172 (Lycoming) Muffler Removal and
Installation, Revision 01, January 17, 2017.
    (2) If no evidence of breaches (leakage) is found during the
inspection required in paragraph (g) of this AD, within the next 100
hours TIS after the effective date of this AD or at the next annual
inspection after the effective date of this AD, whichever occurs
later, replace the affected muffler with an FAA-approved part that
is not a muffler listed in figure 1 of paragraph (c) of this AD
following AWI Cessna 172 (Lycoming) Muffler Removal and
Installation, Revision 01, January 17, 2017.
    (3) After the effective date of this AD, do not install on any
airplane an affected muffler listed in figure 1 of paragraph (c) of
this AD.

 (i) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Chicago Aircraft Certification Office, 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 ACO, send it to the attention of the
person identified in paragraph (j)(1) of this AD.
    (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.
