Discussion The FAA was notified of a software error in the Rockwell Collins GPS– 4000S GPS, part number (P/N) 822– 2189–100, installed on airplanes. The software error can result in an unannunciated inaccurate GPS position in the region within approximately 1,000 miles (+/¥ 20 degrees) of 180 degrees west longitude. The software improperly applies the wide area augmentation system ionospheric delay corrections to the GPS signal from satellites located across the 180th meridian. Due to this anomaly, the position accuracy may be diminished such that the GPS–4000S P/N 822– 2189–100 will not support LPV approaches in the affected region. This condition, if not addressed, could result in a misleading glidepath on an affected LPV approach resulting in CFIT. Related Service Information The FAA reviewed Rockwell Collins Service Information Letter (SIL) GPS– 4X00( )–19–3, Revision No. 2, dated March 25, 2020. The service letter describes the unsafe condition and provides operating limitations for approaches to airports in the affected region until the software is upgraded. The FAA also reviewed Rockwell Collins Service Bulletin GPS–4X00( )– 34–510, Revision No. 1, dated March 6, 2020. The service bulletin specifies procedures for upgrading the GPS– 4000S software, which removes P/N 822–2189–100 and installs P/N 822– 2189–101. FAA’s Determination The FAA is issuing this AD because it 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. AD Requirements This proposed AD would require removing P/N 822–2189–100 GPS– 4000S Global Positioning System(s) from the airplane and installing P/N 822–2189–101 GPS–4000S Global Positioning System(s). Costs of Compliance The FAA estimates that this proposed AD would affect 3,500 airplanes of U.S. registry. The FAA estimates that 2,000 airplanes have two GPS–4000S units installed and 1,500 airplanes have one GPS–4000S unit installed. The FAA estimates the following costs to comply with this proposed AD: jbell on DSKJLSW7X2PROD with PROPOSALS ESTIMATED COSTS Cost on U.S. operators Labor cost Replace GPS–4000S (airplanes with 2 units installed). Replace GPS–4000S (airplanes with single unit installed). 7 work-hours × $85 per hour = $595 ............. $4,540.00 $5,135 $10,270,000 3.50 work-hours × $85 per hour = $297.50 ... 2,270 2,567.50 3,851,250 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. The FAA does not control warranty coverage for affected individuals. As a result, the FAA has included all costs in this 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, VerDate Sep<11>2014 16:26 Oct 28, 2020 Jkt 253001 Parts cost Cost per product Action 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 PO 00000 Frm 00016 Fmt 4702 Sfmt 4702 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 E:\FR\FM\29OCP1.SGM 29OCP1 Federal Register / Vol. 85, No. 210 / Thursday, October 29, 2020 / Proposed Rules 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) 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.

Airworthiness Directives; Rockwell Collins, Inc., Global 
Positioning Systems

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain Rockwell Collins, Inc. (Rockwell Collins), GPS-4000S Global 
Positioning Systems (GPS) installed on airplanes. This proposed AD was 
prompted by an un-annunciated GPS position error, which could cause a

arguments about this proposal. Send your comments to an address listed 
under the ADDRESSES section. Include ``Docket No. FAA-2020-0915; 
Project Identifier AD-2020-00661-Q'' at the beginning of your comments. 
The most helpful comments reference a specific portion of the proposal, 
explain the reason for any recommended change, and include supporting 
data. The FAA will consider all comments received by the closing date 
and may amend this proposal because of those comments.
    Except for Confidential Business Information (CBI) as described in 
the following paragraph, and other information as described in 14 CFR 
11.35, the FAA will post all comments received, without change, to 
https://www.regulations.gov, including any personal information you 
provide. The agency will also post a report summarizing each 
substantive verbal contact we receive about this NPRM.

Confidential Business Information

    CBI is commercial or financial information that is both customarily 
and actually treated as private by its owner. Under the Freedom of 
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public 
disclosure. If your comments responsive to this NPRM contain commercial 
or financial information that is customarily treated as private, that 
you actually treat as private, and that is relevant or responsive to 
this NPRM, it is important that you clearly designate the submitted 
comments as CBI. Please mark each page of your submission containing 
CBI as ``PROPIN.'' The FAA will treat such marked submissions as 
confidential under the FOIA, and they will not be placed in the public 
docket of this NPRM. Submissions containing CBI should be sent to Paul 
Rau, Aerospace Engineer, Wichita ACO Branch, FAA, 1801 Airport Road, 
Wichita, Kansas 67209; phone: 316-946-4149; fax: 316-946-4107; email: 
[email protected] or [email protected]. Any commentary that the FAA 
receives which is not specifically designated as CBI will be placed in 
the public docket for this rulemaking.

Discussion

    The FAA was notified of a software error in the Rockwell Collins 
GPS-4000S GPS, part number (P/N) 822-2189-100, installed on airplanes. 
The software error can result in an un-annunciated inaccurate GPS 
position in the region within approximately 1,000 miles (+/- 20 
degrees) of 180 degrees west longitude. The software improperly applies 
the wide area augmentation system ionospheric delay corrections to the 
GPS signal from satellites located across the 180th meridian. Due to 
this anomaly, the position accuracy may be diminished such that the 
GPS-4000S P/N 822-2189-100 will not support LPV approaches in the 
affected region. This condition, if not addressed, could result in a 
misleading glidepath on an affected LPV approach resulting in CFIT.

Related Service Information

    The FAA reviewed Rockwell Collins Service Information Letter (SIL) 
GPS-4X00( )-19-3, Revision No. 2, dated March 25, 2020. The service 
letter describes the unsafe condition and provides operating 
limitations for approaches to airports in the affected region until the 
software is upgraded.
    The FAA also reviewed Rockwell Collins Service Bulletin GPS-4X00( 
)-34-510, Revision No. 1, dated March 6, 2020. The service bulletin 
specifies procedures for upgrading the GPS-4000S software, which 
removes P/N 822-2189-100 and installs P/N 822-2189-101.

FAA's Determination

    The FAA is issuing this AD because it 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.

AD Requirements

    This proposed AD would require removing P/N 822-2189-100 GPS-4000S 
Global Positioning System(s) from the airplane and installing P/N 822-
2189-101 GPS-4000S Global Positioning System(s).

Costs of Compliance

    The FAA estimates that this proposed AD would affect 3,500 
airplanes of U.S. registry. The FAA estimates that 2,000 airplanes have 
two GPS-4000S units installed and 1,500 airplanes have one GPS-4000S 
unit installed.
    The FAA estimates the following costs to comply with this proposed 
AD:

    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. The FAA does not control warranty coverage for 
affected individuals. As a result, the FAA has included all costs in 
this 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.
    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

[[Page 68503]]

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) 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.

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

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive:

Rockwell Collins, Inc.: Docket No. FAA-2020-0915; Project Identifier 
AD-2020-00661-Q.

(a) Comments Due Date

    The FAA must receive comments by December 14, 2020.

(b) Affected ADs

    None.

(c) Applicability

    This airworthiness directive (AD) applies to Rockwell Collins, 
Inc. GPS-4000S Global Positioning System (GPS) part number (P/N) 
822-2189-100 installed on airplanes, certificated in any category.

(d) Subject

    Joint Aircraft System Component (JASC)/Air Transport Association 
(ATA) of America Code 3400, NAVIGATION SYSTEM.

(e) Unsafe Condition

    This AD was prompted by an un-annunciated GPS vertical error 
that could result in a hazardously misleading localizer performance 
vertical (LPV) glidepath. The FAA is issuing this AD to prevent a 
misleading GPS position on an LPV approach. The unsafe condition, if 
not addressed, result in a misleading GPS position on an LPV 
approach resulting in controlled flight into terrain.

(f) Compliance

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

(g) Actions

    (1) Within 24 months after the effective date of this AD, 
replace GPS-4000S GPS P/N 822-2189-100 with P/N 822-2189-101.
    (2) As of the effective date of this AD, do not install GPS-
4000S GPS P/N 822-2189-100 on any airplane.

 (h) 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 paragraph (i)(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.
