Submissions containing CBI should be sent to Paul Rau, Aviation Safety Engineer, Wichita ACO Branch, FAA, 1801 Airport Road, Wichita, KS 67209. Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background In 2017, the FAA received seven reports of false RAs involving aircraft equipped with Garmin GMN–00962 GTS processor configured for traffic collision avoidance system II (TCAS II) (configuration marketed as GTS–8000 units). The Garmin GMN–00962 GTS processor units are marketed by Garmin as the GTS 825, GTS 855 or GTS 8000, with the marketing name representing the traffic system configuration. A false RA occurs when there is no risk of collision or loss of separation of the airplanes. The FAA review of available air traffic data identified additional false RA incidents occurring at rates as frequent as once every 420 flight hours in congested airspace. These false RAs result from the GTS Processor software potentially calculating incorrect range rates. This results in traffic advisories or RAs being generated when targets are greater than 10 nautical miles (NM) away. A TCAS event involving three or more airplanes can result in mid-air collision by increasing the risk that the TCAS, in resolving the false RA with the initial airplane, will create an actual loss of separation with a third airplane. This condition, if not addressed, could result in an RA being generated when no risk of loss of separation or risk of collision exists between the airplanes involved, which can lead to a mid-air collision with a third airplane. The affected GTS processor units were installed on the airplanes listed below during production; however, the affected units may have been installed on other airplane models as a supplemental type certificate. Although the names found in parenthesis may not be listed on the type certificate, the manufacturer may use those names as marketing names for the airplanes. • Textron Aviation Inc.

E:\FR\FM\14DEP1.SGM 14DEP1 80697 Federal Register / Vol. 85, No. 240 / Monday, December 14, 2020 / Proposed Rules FAA’s Determination The FAA is issuing this NPRM after determining the unsafe condition described previously is likely to exist or develop in other products of these same type design. Related Service Information The FAA reviewed Garmin Service Bulletin No. 2065, Revision A, dated May 7, 2020; and Garmin Service Bulletin No. 1948, Revision B, dated March 26, 2020. These service bulletins contain procedures for uploading the software update to the GMN–00962 GTS Processor units (GTS 825, GTS 855, GTS 8000). Proposed AD Requirements in This NPRM This proposed AD would require updating the GTS processor unit software within 12 months. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 700 appliances installed on airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost Parts cost Cost per product Cost on U.S. operators Update GTS processor software .................... 4 work-hours × $85 per hour = $340 ............. $0 $340 $238,000 Authority for This Rulemaking List of Subjects in 14 CFR Part 39 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 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. VerDate Sep<11>2014 20:48 Dec 11, 2020 Jkt 253001 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 (f) Required Action and Compliance 1. The authority citation for Part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2.

(c) Applicability This AD applies to Garmin International GMN–00962 GTS processor units, part number 011–02571–0( ), with software version 3.13 or earlier, except software version 3.12.1. These units are marketed as the GTS 825, GTS 855, or GTS 8000. (d) Subject Joint Aircraft System Component (JASC) Code 3445, AIR COLLISION AVOIDANCE SYSTEM (TCAS). (e) Unsafe Condition This AD was prompted by the GTS processor unit issuing false resolution advisories (RAs) when no risk of collision or PO 00000 Frm 00031 Fmt 4702 Sfmt 4702 loss of separation exists between the airplanes involved. A traffic collision avoidance system (TCAS) event involving three or more airplanes can result in mid-air collision by increasing the risk that the TCAS, in resolving the false RA between the initial airplane, will create an actual loss of separation with a third airplane. The FAA is issuing this AD to prevent these false RAs, which can lead to a mid-air collision with a third airplane. Within 12 months after the effective date of this AD, update the GTS processor software to a version that is not 3.13 or earlier. (g) Alternative Methods of Compliance (AMOCs) (1) The Manager, Wichita 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 local Flight Standards District Office, as appropriate.

TTY/TDD callers may dial toll free 1–877–889– 5627 for further information. SUPPLEMENTARY INFORMATION: I. Background of This Rulemaking The Longshore and Harbor Workers’ Compensation Act (LHWCA or Act), 33 U.S.C. 901–50, establishes a comprehensive federal workers’ compensation system for an employee’s disability or death arising in the course of covered maritime employment. Metro. Stevedore Co. v. Rambo, 515 U.S. 291, 294 (1995). The Act’s provisions have been extended to (1) contractors working on military bases or U.S. government contracts outside the United States (Defense Base Act, 42 U.S.C. 1651–54); (2) employees of nonappropriated fund instrumentalities (Nonappropriated Fund Instrumentalities Act, 5 U.S.C. 8171– 73); (3) employees engaged in operations that extract natural resources from the outer continental shelf (Outer Continental Shelf Lands Act, 43 U.S.C. 1333(b)); and (4) private employees in the District of Columbia injured prior to July 26, 1982 (District of Columbia Workers’ Compensation Act of May 17, 1928, Public Law 70–419 (formerly codified at 36 D.C. Code 501 et seq. (1973) (repealed 1979)). Consequently, the Act and its extensions cover a broad range of claims for injuries that occur throughout the United States and around the world. OWCP’s sound administration of these programs involves periodic reexamination of the procedures used for claims processing and related issues. OWCP has identified three areas where improvements can be made. The first is expanding electronic filing and requiring private parties to transmit all PO 00000 Frm 00032 Fmt 4702 Sfmt 4702 documents and information to OWCP electronically, except when the individual does not have a computer, lacks access to the internet, or lacks the ability to utilize the internet. Receiving documents and information in electronic form speeds claims administration and simplifies recordkeeping requirements. The second is streamlining settlement procedures. This too should speed the settlement-approval process and lessen the parties’ burdens to submit multiple documents to have a settlement considered. Finally, OWCP is updating its existing penalty regulations and filling a gap by proposing a procedural scheme for employers to challenge penalties assessed against them. These rules will better apprise employers of their obligations and give them a clear path to exercise their rights to challenge any penalty imposed by OWCP. On April 28, 2020, OWCP hosted a public outreach webinar to solicit stakeholders’ views on how OWCP could improve its processes in the three areas covered in this rulemaking. See E.O. 13563, sec. 2(c) (January 18, 2011) (requiring public consultation prior to issuing a proposed regulation). OWCP has considered the feedback received during that session in developing the proposed rules. This rule is not an Executive Order 13771 regulatory action because it is not significant under Executive Order 12866. II. Direct Final Rulemaking In addition to this Notice of Proposed Rulemaking (NPRM), OWCP is concurrently publishing a companion direct final rule (DFR) elsewhere in this issue of the Federal Register. In direct final rulemaking, an agency publishes a DFR in the Federal Register with a statement that the rule will go into effect unless the agency receives significant adverse comment within a specified period. The agency concurrently publishes an identical proposed rule. If the agency receives no significant adverse comment in response to the DFR, the rule goes into effect. If the agency receives significant adverse comment, the agency withdraws the DFR and treats such comment as submissions on the proposed rule. An agency typically uses direct final rulemaking when it anticipates the rule will be non-controversial. By simultaneously publishing this NPRM with a DFR, notice-and-comment rulemaking will be expedited if OWCP receives significant adverse comment and withdraws the DFR. The proposed and direct final rules are substantively identical, and their respective comment E:\FR\FM\14DEP1.SGM 14DEP1

docket of this NPRM. Submissions containing CBI should be sent to Paul 
Rau, Aviation Safety Engineer, Wichita ACO Branch, FAA, 1801 Airport 
Road, Wichita, KS 67209. Any commentary that the FAA receives which is 
not specifically designated as CBI will be placed in the public docket 
for this rulemaking.

Background

    In 2017, the FAA received seven reports of false RAs involving 
aircraft equipped with Garmin GMN-00962 GTS processor configured for 
traffic collision avoidance system II (TCAS II) (configuration marketed 
as GTS-8000 units). The Garmin GMN-00962 GTS processor units are 
marketed by Garmin as the GTS 825, GTS 855 or GTS 8000, with the 
marketing name representing the traffic system configuration.
    A false RA occurs when there is no risk of collision or loss of 
separation of the airplanes. The FAA review of available air traffic 
data identified additional false RA incidents occurring at rates as 
frequent as once every 420 flight hours in congested airspace. These 
false RAs result from the GTS Processor software potentially 
calculating incorrect range rates. This results in traffic advisories 
or RAs being generated when targets are greater than 10 nautical miles 
(NM) away. A TCAS event involving three or more airplanes can result in 
mid-air collision by increasing the risk that the TCAS, in resolving 
the false RA with the initial airplane, will create an actual loss of 
separation with a third airplane.
    This condition, if not addressed, could result in an RA being 
generated when no risk of loss of separation or risk of collision 
exists between the airplanes involved, which can lead to a mid-air 
collision with a third airplane.
    The affected GTS processor units were installed on the airplanes 
listed below during production; however, the affected units may have 
been installed on other airplane models as a supplemental type 
certificate. Although the names found in parenthesis may not be listed 
on the type certificate, the manufacturer may use those names as 
marketing names for the airplanes.
     Textron Aviation Inc. (type certificate previously held by 
Cessna Aircraft Company) Model 525 (Cessna Citation M2), Model 525B 
(Cessna Citation CJ3+), Model Model 680 Sovereign, Model 680A Latitude, 
and Model 700 (Cessna Citation Longitude);

(Phenom 300); and
     Learjet Inc. Model 45 (Learjet 70) and Model 45 (Learjet 
75).

FAA's Determination

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

Related Service Information

    The FAA reviewed Garmin Service Bulletin No. 2065, Revision A, 
dated May 7, 2020; and Garmin Service Bulletin No. 1948, Revision B, 
dated March 26, 2020. These service bulletins contain procedures for 
uploading the software update to the GMN-00962 GTS Processor units (GTS 
825, GTS 855, GTS 8000).

Proposed AD Requirements in This NPRM

    This proposed AD would require updating the GTS processor unit 
software within 12 months.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 700 appliances installed on airplanes of U.S. registry.
    The FAA estimates the following costs to comply with 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 has 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:

Garmin International: Docket No. FAA-2020-0991; Project Identifier 
AD-2020-00478-Q.

(a) Comments Due Date

    The FAA must receive comments on this airworthiness directive 
(AD) by January 28, 2021.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Garmin International GMN-00962 GTS processor 
units, part number 011-02571-0( ), with software version 3.13 or 
earlier, except software version 3.12.1. These units are marketed as 
the GTS 825, GTS 855, or GTS 8000.

(d) Subject

    Joint Aircraft System Component (JASC) Code 3445, AIR COLLISION 
AVOIDANCE SYSTEM (TCAS).

(e) Unsafe Condition

    This AD was prompted by the GTS processor unit issuing false 
resolution advisories (RAs) when no risk of collision or loss of 
separation exists between the airplanes involved. A traffic 
collision avoidance system (TCAS) event involving three or more 
airplanes can result in mid-air collision by increasing the risk 
that the TCAS, in resolving the false RA between the initial 
airplane, will create an actual loss of separation with a third 
airplane. The FAA is issuing this AD to prevent these false RAs, 
which can lead to a mid-air collision with a third airplane.

(f) Required Action and Compliance

    Within 12 months after the effective date of this AD, update the 
GTS processor software to a version that is not 3.13 or earlier.

(g) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Wichita 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 local Flight Standards District 
Office, as appropriate. If sending information directly to the 
manager of the certification office, send it to the attention of the 
person identified in Related Information.
    (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.
