RIN 2120–AA64 Examining the AD Docket DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 Airworthiness Directives; MHI RJ Aviation ULC (Type Certificate Previously Held by Bombardier, Inc.) Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: The FAA proposes to adopt a new airworthiness directive (AD) for certain MHI RJ Aviation ULC Model CL–600–2B19 (Regional Jet Series 100 & 440) airplanes. This proposed AD was prompted by evidence that a revised structural life limit of some components of the nose landing gear (NLG) and/or main landing gear (MLG) was not implemented during repair. This proposed AD would require verifying that the affected components are installed on the airplane, revising the structural life limits in the structural deviation inspection requirements (SDIR) airplane document, and replacing affected components 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 November 19, 2020. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: • Federal eRulemaking Portal: Go to https://www.regulations.gov.

Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian AD CF–2020–09, dated April 7, 2020 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain MHI RJ Aviation ULC Model CL–600–2B19 (Regional Jet Series 100 & 440) airplanes. You may examine the MCAI in the AD docket on the internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2020– 0691. This proposed AD was prompted by evidence that some components of the NLG and/or MLG were repaired using Bombardier Repair Engineering Orders (REOs) that resulted in a specific airworthiness limitation (SAL). In certain cases, the related SDIRs were not attached to the REO when the parts were repaired and provided to the operator. Consequently, the SDIR was not incorporated into the SDIR airplane document and the revised life limit of the repaired NLG and/or MLG components, as indicated in the SDIR, was not implemented. Those parts, repaired by REO that resulted in an SDIR, have a structural life limit that is lower than the life limit published in the Maintenance Requirements Manual (MRM). The FAA is proposing this AD to address structural life limits that are lower than the life limit published in the MRM, Part 2. This condition, if not corrected, could lead to the collapse of the affected NLG and/or MLG, possibly resulting in airplane damage and injury to the occupants. See the MCAI for additional background information.

FAA’s Determination This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, the FAA has been notified of the unsafe condition described in the MCAI and service E:\FR\FM\05OCP1.SGM 05OCP1 62628 Federal Register / Vol. 85, No. 193 / Monday, October 5, 2020 / Proposed Rules information referenced above. The FAA is proposing this AD because the FAA evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop on other products of the same type design. Proposed Requirements of this NPRM This proposed AD would require accomplishing the actions specified in the service information described previously, except as discussed under ‘‘Differences Between this Proposed AD and the MCAI or Service Information.’’ Costs of Compliance The FAA estimates that this proposed AD affects 456 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Up to 143 work-hours × $85 per hour = Up to $12,155. Up to $103,114 ............................. Up to $115,269 ............................. Authority for This Rulemaking The Proposed Amendment 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. Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: jbell on DSKJLSW7X2PROD with PROPOSALS 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) 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.

(d) Subject Air Transport Association (ATA) of America Code 32, Landing gear. (e) Reason This AD was prompted by evidence that a revised structural life limit of some components of the nose landing gear (NLG) and/or main landing gear (MLG) was not implemented during repair. The FAA is issuing this AD to address structural life limits that are lower than the life limits published in the Maintenance Requirements Manual (MRM), Part 2. This condition, if not corrected, could lead to the collapse of the affected NLG and/or MLG, possibly resulting in airplane damage and injury to the occupants.

RIN 2120-AA64


Airworthiness Directives; MHI RJ Aviation ULC (Type Certificate 
Previously Held by Bombardier, Inc.) Airplanes

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 MHI RJ Aviation ULC Model CL-600-2B19 (Regional Jet Series 
100 & 440) airplanes. This proposed AD was prompted by evidence that a 
revised structural life limit of some components of the nose landing 
gear (NLG) and/or main landing gear (MLG) was not implemented during 
repair. This proposed AD would require verifying that the affected 
components are installed on the airplane, revising the structural life 
limits in the structural deviation inspection requirements (SDIR) 
airplane document, and replacing affected components 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 November 
19, 2020.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

and may amend this NPRM 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 FAA will also post a report summarizing each substantive 
verbal contact received 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 the 
person identified in the FOR FURTHER INFORMATION CONTACT section. Any 
commentary that the FAA receives which is not specifically designated 
as CBI will be placed in the public docket for this rulemaking.

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2020-09, dated April 7, 
2020 (referred to after this as the Mandatory Continuing Airworthiness 
Information, or ``the MCAI''), to correct an unsafe condition for 
certain MHI RJ Aviation ULC Model CL-600-2B19 (Regional Jet Series 100 
& 440) airplanes. You may examine the MCAI in the AD docket on the 
internet at https://www.regulations.gov by searching for and locating 
Docket No. FAA-2020-0691.
    This proposed AD was prompted by evidence that some components of 
the NLG and/or MLG were repaired using Bombardier Repair Engineering 
Orders (REOs) that resulted in a specific airworthiness limitation 
(SAL). In certain cases, the related SDIRs were not attached to the REO 
when the parts were repaired and provided to the operator. 
Consequently, the SDIR was not incorporated into the SDIR airplane 
document and the revised life limit of the repaired NLG and/or MLG 
components, as indicated in the SDIR, was not implemented. Those parts, 
repaired by REO that resulted in an SDIR, have a structural life limit 
that is lower than the life limit published in the Maintenance 
Requirements Manual (MRM). The FAA is proposing this AD to address 
structural life limits that are lower than the life limit published in 
the MRM, Part 2. This condition, if not corrected, could lead to the 
collapse of the affected NLG and/or MLG, possibly resulting in airplane 
damage and injury to the occupants. See the MCAI for additional 
background information.

    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.

FAA's Determination

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, the FAA 
has been notified of the unsafe condition described in the MCAI and 
service

[[Page 62628]]

information referenced above. The FAA is proposing this AD because the 
FAA evaluated all the relevant information and determined the unsafe 
condition described previously is likely to exist or develop on other 
products of the same type design.

Proposed Requirements of this NPRM

    This proposed AD would require accomplishing the actions specified 
in the service information described previously, except as discussed 
under ``Differences Between this Proposed AD and the MCAI or Service 
Information.''

Costs of Compliance

    The FAA estimates that this proposed AD affects 456 airplanes of 
U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
              Labor cost                      Parts cost            Cost per product      Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 143 work-hours x $85 per hour =  Up to $103,114.........  Up to $115,269.........  Up to $52,562,664.
 Up to $12,155.
----------------------------------------------------------------------------------------------------------------

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) 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.

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 (AD):

MHI RJ Aviation ULC (Type Certificate Previously Held by Bombardier, 
Inc.): Docket No. FAA-2020-0691; Product Identifier 2020-NM-064-AD.

(a) Comments Due Date

    The FAA must receive comments by November 19, 2020.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to MHI RJ Aviation ULC (type certificate 
previously held by Bombardier, Inc.) Model CL-600-2B19 (Regional Jet 
Series 100 & 440) airplanes, certificated in any category, serial 
numbers 7003 through 8999 inclusive.

(d) Subject

    Air Transport Association (ATA) of America Code 32, Landing 
gear.

(e) Reason

    This AD was prompted by evidence that a revised structural life 
limit of some components of the nose landing gear (NLG) and/or main 
landing gear (MLG) was not implemented during repair. The FAA is 
issuing this AD to address structural life limits that are lower 
than the life limits published in the Maintenance Requirements 
Manual (MRM), Part 2. This condition, if not corrected, could lead 
to the collapse of the affected NLG and/or MLG, possibly resulting 
in airplane damage and injury to the occupants.

(f) Compliance

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

(g) Verification of Airplane or Technical Records

    Within 6 months from the effective date of this AD: Verify the 
airplane or technical records to determine if an NLG or MLG 
component listed in Table 1 or Table 2 of Bombardier Service 
Bulletin 601R-32-112, dated November 11, 2019, is installed on the 
airplane. If this verification determines that an affected component 
listed in Table 1 or Table 2 of Bombardier Service Bulletin 601R-32-
112, dated November 11, 2019, is installed on the airplane, perform 
the actions specified in paragraph (h) or (i) of this AD, as 
applicable.

(h) Incorporation of the SDIR Life Limit Into the SDIR Airplane 
Document

    If the total flight cycles of the component is less than the 
revised SDIR life limit specified in the applicable REO identified 
in paragraphs (h)(1) through (58) of this AD minus 2,000 flight 
cycles: Within 12 months after completing the actions specified in 
paragraph (g) of this AD, incorporate the revised life limit of the 
affected component into the existing SDIR airplane document as 
specified in the applicable REO identified in paragraphs (h)(1) 
through (58) of this AD.
