Airworthiness Directives; Mooney International Corporation Airplanes, 13502-13505 [2021-04591]

Download as PDF khammond on DSKJM1Z7X2PROD with PROPOSALS 13502 Federal Register / Vol. 86, No. 44 / Tuesday, March 9, 2021 / Proposed Rules subject to a two-quarter grace period if they do not meet any of the eligibility criteria and may remain under the CBLR framework, provided that their leverage ratio is above seven percent during the grace period. Beginning in 2021, the CBLR requirement will be 8.5 percent or greater and the minimum requirement during the grace period will be 7.5 percent.30 Beginning in 2022, the CBLR requirement will return to nine percent and the minimum requirement during the grace period will return to eight percent. In the preamble to the 2019 Supplemental Rule, the Board explained that it might consider a capital standard analog to the CBLR framework developed by the other banking agencies—referred to in this ANPR as CCULR. The CCULR approach would be based on the principles of the CBLR framework and, for complex credit unions that meet specified qualifying criteria and have opted into the approach, would provide relief from the requirement to calculate a risk-based capital ratio, as implemented by the 2015 Final Rule. In exchange, the qualifying complex credit union would be required to maintain a higher net worth ratio than is otherwise required for the well-capitalized classification. This is a similar trade-off to the one made by qualifying community banking organizations under the CBLR. As noted above, the 2015 Final Rule is scheduled to take effect on January 1, 2022. Accordingly, a CCULR approach would be parallel to the 2015 Final Rule and would not take effect until January 1, 2022. Qualifying complex credit unions would not be able to opt into the proposed CCULR approach prior to this effective date. In designing the CCULR, the Board would seek to further the goal of the FCUA’s PCA requirements by requiring that complex credit unions continue to hold capital commensurate with their risks, while minimizing the burden associated with complying with the NCUA’s risk-based capital requirement. The Board welcomes comments on a possible adoption of the CCULR and, in particular, seeks input on the following issues: Question 5: The Board invites comments on the merits of incorporating the CCULR in its capital adequacy regulations. Should the NCUA capital framework be amended to adopt an ‘‘off-ramp’’ such as the CCULR to the risk-based capital requirements of the 2015 Final Rule? Question 6: The Board invites comment on the criteria for CCULR 30 See, 85 FR 22930 (Apr. 23, 2020). VerDate Sep<11>2014 16:42 Mar 08, 2021 Jkt 253001 eligibility. Should the Board adopt the same qualifying criteria as established by the other banking agencies for the CBLR? In recommending qualifying criteria regarding a credit union’s risk profile, please provide information on how the qualifying criteria should be considered in conjunction with the calibration of the CCULR level under question 7, below. Question 7: What assets and liabilities on a FICU’s Call Report should the Board consider in determining the net worth threshold? How should each of these items be weighted? Question 8: What are the advantages and disadvantages of using the net worth ratio as the measure of capital adequacy under the CCULR? Should the Board consider alternative measures for the CCULR? For example, instead of the existing net worth definition, the CCULR could use the risk-based capital ratio numerator from the 2015 Final Rule, similar to the ‘‘Tier 1 Capital’’ measure used for banking institutions. Question 9: Should all complex credit unions be eligible for the CCULR, or should the Board limit eligibility to a subset of these credit unions? For example, the Board could consider limiting eligibility to the CCULR approach to only complex credit unions with less than $10 billion in total assets. Question 10: The Board invites comment on the procedures a qualifying complex credit union would use to opt into or out of the CCULR approach. What are commenters’ views on the frequency with which a qualifying complex credit union may opt into or out of the CCULR approach? What are the operational or other challenges associated with switching between frameworks? Question 11: The Board invites comment on the treatment for a complex credit union that no longer meets the definition of a qualifying complex credit union after opting into the CCULR approach. Should the Board consider requiring complex credit unions that no longer meet the qualifying criteria to begin to calculate their assets immediately according to the risk-based capital ratio? Should the Board provide a grace period for these credit unions to come back into compliance with the CCULR and, if so, how long of a grace period is appropriate? What other alternatives should the Board consider with respect to a complex credit union that no longer meets the definition of a qualifying complex credit union and why? Is notification that a credit union will not meet the qualifying criteria necessary? PO 00000 Frm 00009 Fmt 4702 Sfmt 4702 VI. Timeline As discussed above, the 2015 Final Rule will be effective January 1, 2022. The Board expects that any final rule developed in response to this ANPR would be issued before the effective date of the 2015 Final Rule. Accordingly, the Board expects that any notice of proposed rulemaking issued in response to this ANPR would be issued by midyear of 2021. Once comments are received, the Board will evaluate the comments and direct NCUA staff to move forward in drafting any proposed rule to meet this timeline. VII. Conclusion The Board is committed to tailoring its capital requirements to the unique features of credit unions. The two approaches outlined in this ANPR are designed to accomplish this goal without reducing the effectiveness of the Board’s capital standards. The RBLR approach would replace the 2015 Final Rule risk-based capital requirements using relevant risk attribute thresholds that would require additional capital buffers. The CCULR would enable eligible complex FICUs to opt-into a framework to meet all regulatory capital requirements. The Board invites comments on these two options, as well as on any other recommendations that might similarly accomplish the goals outlined in this ANPR. All comments will be considered in the development of a future proposed rule. By the National Credit Union Administration Board, this 14th day of January, 2021.

SUPPLEMENTARY INFORMATION: VerDate Sep<11>2014 16:42 Mar 08, 2021 Jkt 253001 Comments Invited The FAA invites you to send any written relevant data, views, or arguments about this proposal. Send your comments to an address listed under ADDRESSES. Include ‘‘Docket No. FAA–2020–0991; Project Identifier AD– 2020–00539–A’’ 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 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 Jacob Fitch, Aviation Safety Engineer, Fort Worth ACO Branch, FAA, 10101 Hillwood Pkwy., Fort Worth, TX 76177. Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background The FAA received a report that two Mooney Model M20V airplanes had short circuit arcing of the alternator main power cable in the engine compartment. Mooney determined the alternator main power cable was incorrectly positioned with slack in the cable and allowed contact between the alternator main power cable and PO 00000 Frm 00010 Fmt 4702 Sfmt 4702 13503 turbocharger right-hand (RH) exhaust crossover tube. In one instance, this contact caused arcing of the alternator main power cable and created a hole in the RH exhaust crossover tube, which may result in a fire hazard. A damaged crossover tube may also decrease effectiveness of the turbochargers and cause complete loss of engine power at higher altitudes (above 9,000 ft. above sea level). This condition, if not addressed, could result in an inflight fire and loss of engine thrust control, which may lead to reduced control of the airplane. Related Service Information Under 1 CFR Part 51 The FAA reviewed Mooney International Corporation Service Bulletin M20–340C, dated February 14, 2020 (SB M20–340C). The service information specifies inspecting the alternator main power cable and the exhaust crossover tube for damage and replacing damaged parts as necessary. The service information also contains procedures for modifying the alternator main power cable routing by installing an additional alternator cable clamp, part number MS21919WCJ6. 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 The FAA is issuing this NPRM after determining the unsafe condition described previously is likely to exist or develop in other products of the same type design. Proposed AD Requirements in 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 Service Information.’’ Differences Between This Proposed AD and the Service Information SB M20–340C specifies sending a compliance card to Mooney upon completing the actions in the service information. This proposed AD would not require that action. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 18 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: E:\FR\FM\09MRP1.SGM 09MRP1 13504 Federal Register / Vol. 86, No. 44 / Tuesday, March 9, 2021 / Proposed Rules ESTIMATED COSTS Cost per product Labor cost Inspect the cable and exhaust crossover tube for damage. Install additional cable clamp .......................... .5 work-hour × $85 per hour = $42.50 ........... $0 $42.50 $765 .5 work-hour × $85 per hour = $42.50 ........... 10 52.50 945 The FAA estimates the following costs to do any necessary repairs/ replacements that would be required Parts cost Cost on U.S. operators Action based on the results of the proposed inspection. The agency has no way of determining the number of aircraft that might need these repairs/replacements: ON-CONDITION COSTS Action Labor cost Replace alternator main power cable .......................... Replace exhaust crossover tube .................................. 8 work-hours × $85 per hour = $680 ........................... 8 work-hours × $85.00 per hour = $680 ...................... The FAA has included all known costs in its cost estimate. According to the manufacturer, however, some of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected operators. 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 proposing 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. khammond on DSKJM1Z7X2PROD 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: VerDate Sep<11>2014 16:42 Mar 08, 2021 Jkt 253001 (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 1.

ACTION: Proposed rule; withdrawal. AGENCY: The FAA is withdrawing a notice of proposed rulemaking (NPRM) that proposed to adopt a new airworthiness directive (AD) that would have applied to certain Bell Helicopter Textron Canada Model 206A, 206B, and 206B3 helicopters. The NPRM was prompted by the need for corresponding operating limitations prohibiting flight, including hover, with the litter doorpost removed when certain litter kits are installed. The NPRM would have required revising the Operating Limitations, Section 1, of the existing Rotorcraft Flight Manual (RFM) for your khammond on DSKJM1Z7X2PROD with PROPOSALS SUMMARY: VerDate Sep<11>2014 16:42 Mar 08, 2021 Jkt 253001 helicopter to add an operating limitation when a litter kit is installed to prohibit flight with the doorpost removed to prevent loss of structural integrity of the fuselage. Since issuance of the NPRM, the FAA has determined that an unsafe condition no longer exists. Accordingly, the NPRM is withdrawn.

SUPPLEMENTARY INFORMATION: Discussion The FAA has issued an NPRM that proposed to amend 14 CFR part 39 by adding an AD that would apply to the specified products. The NPRM was published in the Federal Register on May 13, 2011 (76 FR 27958). The NPRM was prompted by the need for corresponding operating limitations prohibiting flight, including hover, with the litter doorpost removed when certain litter kits are installed. The NPRM proposed to require revising the existing RFM for your helicopter by inserting into the Operating Limitations, Section 1, of the existing RFM for your helicopter the following statement: ‘‘Flight, including hover, with litter doorpost removed is prohibited.’’ This revision would have been made by pen and ink changes, inserting a copy of this AD into the existing RFM for your helicopter, or inserting a copy of the RFM Supplement (RFMS) dealing with Litter Kits into the existing RFM for your helicopter as follows: For Model 206A helicopters— inserting RFMS BHT–206A–FMS–8, dated December 30, 2009, into RFM BHT–206A–FM–1, dated July 2, 2009; PO 00000 Frm 00012 Fmt 4702 Sfmt 4702 13505 for Model 206B helicopters—inserting RFMS BHT–206B–FMS–8, dated December 30, 2009, into RFM BHT– 206B–FM–1, dated July 2, 2009; and for Model 206B3 helicopters—inserting RFMS BHT–206B3–FMS–2, dated December 30, 2009, into RFM BHT– 206B3–FM–1, dated March 24, 2010. The proposed actions were intended to add an operating limitation when a litter kit is installed to prohibit flight with the doorpost removed to prevent loss of structural integrity of the fuselage. Actions Since the NPRM Was Issued Since issuance of the NPRM, reevaluation of current fleet safety data indicates that there is not an unsafe condition and AD action is no longer necessary. There are no recent records of safety issues related to the unsafe condition previously described. Therefore, the FAA has determined that AD action is not required. Withdrawal of the NPRM constitutes only such action and does not preclude the agency from issuing future rulemaking on this issue, nor does it commit the agency to any course of action in the future. The FAA’s Aircraft Certification Service has also changed its organizational structure. The new structure replaces product directorates with functional divisions. We have revised some of the office titles and nomenclature throughout this proposed AD to reflect the new organizational changes. Additional information about the new structure can be found in the Notice published on July 25, 2017 (82 FR 34564). Lastly, the identification of ‘‘Directorate Identifier 2010–SW–021– AD’’ has been changed to ‘‘Project Identifier AD 2020–01464–R.’’ Comments The FAA gave the public the opportunity to comment on the NPRM. The FAA received no comments on the NPRM or on the determination of the cost to the public. FAA’s Conclusions Upon further consideration, the FAA has determined that the NPRM is unnecessary. Accordingly, the NPRM is withdrawn. Regulatory Findings Since this action only withdraws an NPRM, it is neither a proposed nor a final rule. This action therefore is not covered under Executive Order 12866, the Regulatory Flexibility Act, or DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979).

confidential under the FOIA, and they will not be placed in the public 
docket of this NPRM. Submissions containing CBI should be sent to Jacob 
Fitch, Aviation Safety Engineer, Fort Worth ACO Branch, FAA, 10101 
Hillwood Pkwy., Fort Worth, TX 76177. Any commentary that the FAA 
receives which is not specifically designated as CBI will be placed in 
the public docket for this rulemaking.

Background

    The FAA received a report that two Mooney Model M20V airplanes had 
short circuit arcing of the alternator main power cable in the engine 
compartment. Mooney determined the alternator main power cable was 
incorrectly positioned with slack in the cable and allowed contact 
between the alternator main power cable and turbocharger right-hand 
(RH) exhaust crossover tube. In one instance, this contact caused 
arcing of the alternator main power cable and created a hole in the RH 
exhaust crossover tube, which may result in a fire hazard. A damaged 
crossover tube may also decrease effectiveness of the turbochargers and 
cause complete loss of engine power at higher altitudes (above 9,000 
ft. above sea level). This condition, if not addressed, could result in 
an inflight fire and loss of engine thrust control, which may lead to 
reduced control of the airplane.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Mooney International Corporation Service Bulletin 
M20-340C, dated February 14, 2020 (SB M20-340C). The service 
information specifies inspecting the alternator main power cable and 
the exhaust crossover tube for damage and replacing damaged parts as 
necessary. The service information also contains procedures for 
modifying the alternator main power cable routing by installing an 
additional alternator cable clamp, part number MS21919WCJ6.
    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

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

Proposed AD Requirements in 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 Service 
Information.''

Differences Between This Proposed AD and the Service Information

    SB M20-340C specifies sending a compliance card to Mooney upon 
completing the actions in the service information. This proposed AD 
would not require that action.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 18 airplanes of U.S. registry.
    The FAA estimates the following costs to comply with this proposed 
AD:

    The FAA estimates the following costs to do any necessary repairs/
replacements that would be required based on the results of the 
proposed inspection. The agency has no way of determining the number of 
aircraft that might need these repairs/replacements:

    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, some of the costs of this 
proposed AD may be covered under warranty, thereby reducing the cost 
impact on affected operators.

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 proposing 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) 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.
