Discussion The FAA issued AD 2015–05–03, Amendment 39–18113 (80 FR 13758, March 17, 2015) (‘‘AD 2015–05–03’’), for certain MHI RJ Aviation ULC Model CL–600–2B19 (Regional Jet Series 100 & 440) airplanes. AD 2015–05–03 requires revising the maintenance or inspection program, as applicable, to incorporate new or revised maintenance requirements and airworthiness limitations, and incorporating structural repairs and modifications to preclude VerDate Sep<11>2014 17:18 Oct 13, 2020 Jkt 253001 WFD. AD 2015–05–03 resulted from reports of cracking on the skin panels and skin splice joints and angles at certain stringers at various locations between certain fuselage stations. The FAA issued AD 2015–05–03 to address WFD, which could adversely affect the structural integrity of the airplane. Actions Since AD 2015–05–03 Was Issued Since the FAA issued AD 2015–05– 03, the FAA has determined that new or more restrictive airworthiness limitations are necessary, as well as the corresponding structural repairs and modifications to preclude WFD. Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian AD CF–2014–07R1, dated July 13, 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– 0913. This proposed AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary, as well as the corresponding structural repairs and modifications to preclude WFD. The manufacturer discovered inconsistencies between the Engineering Structure Reports and Maintenance Tasks for the inspection of fuselage skin longitudinal splices along a certain stringer. The FAA is proposing this AD to address WFD, which could adversely affect the structural integrity of the airplane. See the MCAI for additional background information. Related Service Information Under 1 CFR Part 51 MHI RJ Aviation has issued Bombardier Temporary Revision 2B– 2280, dated June 12, 2020. This service information, among other actions, describes airworthiness limitation (AWL) task 53–41–207, which specifies airworthiness limitations and inspections for fuselage and longitudinal skin splices at stringer (STR) 6 and 20. This proposed AD would also require the following service information, which the Director of the Federal Register approved for incorporation by reference as of April 21, 2015 (80 FR 13758, March 17, 2015). • AWL Task 53–41–110, Longitudinal Str. 6 splice butt strap at Str. 6, FS409.0 to FS617.0, of Appendix B, PO 00000 Frm 00008 Fmt 4702 Sfmt 4702 Airworthiness Limitations, of Part 2, Airworthiness Requirements, Revision 9, dated June 10, 2013, of the Bombardier CL–600–2B19 Maintenance Requirements Manual, CSP A–053. • AWL Task 53–41–204, Frame splice angles at STR 6 and 20, of Appendix B, Airworthiness Limitations, of Part 2, Airworthiness Requirements, Revision 9, dated June 10, 2013, of the Bombardier CL–600–2B19 Maintenance Requirements Manual, CSP A–053. 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 the FAA’s bilateral agreement with the State of Design Authority, the FAA has been notified of the unsafe condition described in the MCAI and service 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 retain certain requirements of AD 2015–05–03. This proposed AD would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations and would require incorporating structural repairs and modifications to preclude WFD. This proposed AD would require revisions to certain operator maintenance documents to include new actions (e.g., inspections). Compliance with these actions is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by this proposed AD, the operator may not be able to accomplish the actions described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (n)(1) of this proposed AD. Costs of Compliance The FAA estimates that this proposed AD affects 431 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: The FAA estimates the total cost per operator for the retained actions from E:\FR\FM\14OCP1.SGM 14OCP1 Federal Register / Vol. 85, No. 199 / Wednesday, October 14, 2020 / Proposed Rules AD 2015–05–03 to be $7,650 (90 workhours × $85 per work-hour). The FAA has determined that revising the maintenance or inspection program takes an average of 90 work-hours per operator, although the agency recognizes that this number may vary from operator to operator. In the past, the agency has estimated that this action takes 1 work-hour per airplane. Since operators incorporate maintenance or inspection program changes for their affected fleet(s), the FAA has determined that a per-operator estimate is more accurate than a per-airplane estimate. Therefore, the agency estimates the average total cost per operator to be $7,650 (90 work-hours × $85 per work-hour). The FAA has received no definitive data that would enable us to provide cost estimates for the repairs and modifications specified in this proposed AD. jbell on DSKJLSW7X2PROD with PRO_RULES 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, VerDate Sep<11>2014 17:18 Oct 13, 2020 Jkt 253001 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.

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 has received reports of the airplane power lever linkage detaching from the TPE331 engine PPC shaft. In flight operations, detachment may result in fuel flow to the engine remaining constant regardless of the power lever movement by the pilot. The orientation of the engine on certain M7 Aerospace LLC airplanes increases the vulnerability of detachment. The PPC lever is an airplane part and its detachment from the TPE331 has been the subject of previous ADs on other airplane type designs. This condition, if not addressed, could result in uncommanded change to the engine power settings with consequent loss of control. Related Service Information Under 1 CFR Part 51 The FAA reviewed Honeywell International Inc. Service Bulletin TPE331–72–2190, dated December 21, 2011, which contains procedures for replacing or reworking the propeller pitch control assembly, incorporating a threaded hole in the splined end of the shouldered shaft, and reassembling the propeller pitch control assembly. 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.

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 supersede Airworthiness Directive (AD) 
2015-05-03, which applies to certain MHI RJ Aviation ULC Model CL-600-
2B19 (Regional Jet Series 100 & 440) airplanes. AD 2015-05-03 requires 
revising the maintenance or inspection program, as applicable, to 
incorporate new or revised maintenance requirements and airworthiness 
limitations, and incorporating structural repairs and modifications to 
preclude widespread fatigue damage (WFD). Since the FAA issued AD 2015-
05-03, the FAA has determined that new or more restrictive 
airworthiness limitations are necessary, as well as the corresponding 
structural repairs and modifications to preclude WFD. This proposed AD 
would require revising the existing maintenance or inspection program, 
as applicable, to incorporate new or more restrictive airworthiness 
limitations and would require incorporating structural repairs and 
modifications to preclude WFD. 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 
30, 2020.

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

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 
Andrea Jimenez, Aerospace Engineer, Airframe and Propulsion Section, 
FAA, New York ACO Branch, 1600 Stewart Avenue, Suite 410, Westbury, NY 
11590; phone: 516-228-7330; fax: 516-794-5531; email: [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 issued AD 2015-05-03, Amendment 39-18113 (80 FR 13758, 
March 17, 2015) (``AD 2015-05-03''), for certain MHI RJ Aviation ULC 
Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. AD 2015-
05-03 requires revising the maintenance or inspection program, as 
applicable, to incorporate new or revised maintenance requirements and 
airworthiness limitations, and incorporating structural repairs and 
modifications to preclude WFD. AD 2015-05-03 resulted from reports of 
cracking on the skin panels and skin splice joints and angles at 
certain stringers at various locations between certain fuselage 
stations. The FAA issued AD 2015-05-03 to address WFD, which could 
adversely affect the structural integrity of the airplane.

Actions Since AD 2015-05-03 Was Issued

    Since the FAA issued AD 2015-05-03, the FAA has determined that new 
or more restrictive airworthiness limitations are necessary, as well as 
the corresponding structural repairs and modifications to preclude WFD.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2014-07R1, dated July 
13, 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-2020-0913.
    This proposed AD was prompted by a determination that new or more 
restrictive airworthiness limitations are necessary, as well as the 
corresponding structural repairs and modifications to preclude WFD. The 
manufacturer discovered inconsistencies between the Engineering 
Structure Reports and Maintenance Tasks for the inspection of fuselage 
skin longitudinal splices along a certain stringer. The FAA is 
proposing this AD to address WFD, which could adversely affect the 
structural integrity of the airplane. See the MCAI for additional 
background information.

Related Service Information Under 1 CFR Part 51

    MHI RJ Aviation has issued Bombardier Temporary Revision 2B-2280, 
dated June 12, 2020. This service information, among other actions, 
describes airworthiness limitation (AWL) task 53-41-207, which 
specifies airworthiness limitations and inspections for fuselage and 
longitudinal skin splices at stringer (STR) 6 and 20.
    This proposed AD would also require the following service 
information, which the Director of the Federal Register approved for 
incorporation by reference as of April 21, 2015 (80 FR 13758, March 17, 
2015).
     AWL Task 53-41-110, Longitudinal Str. 6 splice butt strap 
at Str. 6, FS409.0 to FS617.0, of Appendix B, Airworthiness 
Limitations, of Part 2, Airworthiness Requirements, Revision 9, dated 
June 10, 2013, of the Bombardier CL-600-2B19 Maintenance Requirements 
Manual, CSP A-053.
     AWL Task 53-41-204, Frame splice angles at STR 6 and 20, 
of Appendix B, Airworthiness Limitations, of Part 2, Airworthiness 
Requirements, Revision 9, dated June 10, 2013, of the Bombardier CL-
600-2B19 Maintenance Requirements Manual, CSP A-053.
    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 the FAA's bilateral agreement with the State of Design Authority, 
the FAA has been notified of the unsafe condition described in the MCAI 
and service 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 retain certain requirements of AD 2015-05-
03. This proposed AD would require revising the existing maintenance or 
inspection program, as applicable, to incorporate new or more 
restrictive airworthiness limitations and would require incorporating 
structural repairs and modifications to preclude WFD.
    This proposed AD would require revisions to certain operator 
maintenance documents to include new actions (e.g., inspections). 
Compliance with these actions is required by 14 CFR 91.403(c). For 
airplanes that have been previously modified, altered, or repaired in 
the areas addressed by this proposed AD, the operator may not be able 
to accomplish the actions described in the revisions. In this 
situation, to comply with 14 CFR 91.403(c), the operator must request 
approval for an alternative method of compliance according to paragraph 
(n)(1) of this proposed AD.

Costs of Compliance

    The FAA estimates that this proposed AD affects 431 airplanes of 
U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:
    The FAA estimates the total cost per operator for the retained 
actions from

[[Page 64989]]

AD 2015-05-03 to be $7,650 (90 work-hours x $85 per work-hour).
    The FAA has determined that revising the maintenance or inspection 
program takes an average of 90 work-hours per operator, although the 
agency recognizes that this number may vary from operator to operator. 
In the past, the agency has estimated that this action takes 1 work-
hour per airplane. Since operators incorporate maintenance or 
inspection program changes for their affected fleet(s), the FAA has 
determined that a per-operator estimate is more accurate than a per-
airplane estimate. Therefore, the agency estimates the average total 
cost per operator to be $7,650 (90 work-hours x $85 per work-hour).
    The FAA has received no definitive data that would enable us to 
provide cost estimates for the repairs and modifications specified in 
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 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.
