SUPPLEMENTARY INFORMATION: 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–2021–0223; 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 the NPRM. Confidential Business Information CBI is commercial or financial information that is both customarily and PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 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 the 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 the 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 published an NPRM (86 FR 13502, March 9, 2021) that would apply to certain serial-numbered Mooney Model M20V airplanes. The NPRM proposed to require inspecting the alternator main power cable and the exhaust crossover tube and modifying the alternator main power cable routing by installing an additional alternator cable clamp, part number MS21919WCJ6. The NPRM was prompted by reports of short circuit and arcing of the alternator main power cable in the engine compartment. This condition, if unaddressed, could result in a fire hazard, loss of engine thrust control, and reduced control of the airplane. Need for the Correction As published, the docket number referenced throughout the NPRM is incorrect. The NPRM incorrectly references ‘‘Docket No. FAA–2020– 0991’’ instead of ‘‘Docket No. FAA– 2021–0223.’’ Although no other part of the preamble or regulatory information has been corrected, for clarity, the FAA is publishing the entire proposed rule in the Federal Register. The comment due date of the NPRM remains April 23, 2021. 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 E:\FR\FM\17MRP1.SGM 17MRP1 14555 Federal Register / Vol. 86, No. 50 / Wednesday, March 17, 2021 / Proposed Rules 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: 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. jbell on DSKJLSW7X2PROD with PROPOSALS 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 VerDate Sep<11>2014 17:42 Mar 16, 2021 Jkt 253001 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. Parts cost $1,000 2,500 Cost per product $1,680 3,180 Correction 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. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Corrected] 2. The FAA amends § 39.13 by adding the following new airworthiness directive: ■ Mooney International Corporation: Docket No. FAA–2021–0223; Project Identifier AD–2020–00539–A.

SUPPLEMENTARY INFORMATION:

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-2021-0223; 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 the 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 
the 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 the 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 published an NPRM (86 FR 13502, March 9, 2021) that would 
apply to certain serial-numbered Mooney Model M20V airplanes. The NPRM 
proposed to require inspecting the alternator main power cable and the 
exhaust crossover tube and modifying the alternator main power cable 
routing by installing an additional alternator cable clamp, part number 
MS21919WCJ6. The NPRM was prompted by reports of short circuit and 
arcing of the alternator main power cable in the engine compartment. 
This condition, if unaddressed, could result in a fire hazard, loss of 
engine thrust control, and reduced control of the airplane.

Need for the Correction

    As published, the docket number referenced throughout the NPRM is 
incorrect. The NPRM incorrectly references ``Docket No. FAA-2020-0991'' 
instead of ``Docket No. FAA-2021-0223.''
    Although no other part of the preamble or regulatory information 
has been corrected, for clarity, the FAA is publishing the entire 
proposed rule in the Federal Register.
    The comment due date of the NPRM remains April 23, 2021.

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

[[Page 14555]]

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 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.

Correction

    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  [Corrected]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive:

Mooney International Corporation: Docket No. FAA-2021-0223; Project 
Identifier AD-2020-00539-A.

(a) Comments Due Date

    The FAA must receive comments on this airworthiness directive 
(AD) by April 23, 2021.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Mooney International Corporation Model M20V 
airplanes, serial

[[Page 14556]]

numbers 33-0001 through 33-0018, certificated in any category.

 (d) Subject

    Joint Aircraft System Component Code 2400, Electrical Power 
System.

(e) Unsafe Condition

    This AD was prompted by reports of short circuit and arcing of 
the alternator main power cable in the engine compartment. The FAA 
is issuing this AD to prevent arcing of the alternator main power 
cable in the engine compartment. 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.

(f) Compliance

    Comply with this AD before further flight after the effective 
date of this AD, unless already done.

(g) Required Actions

    (1) Inspect the alternator main power cable and the exhaust 
crossover tube for burn marks, chafing, holes, and cracks, and 
replace any cable and crossover tube that has a burn mark, chafing, 
a hole, or a crack.
    (2) Install an additional alternator cable clamp part number 
MS21919WCJ6 and ensure correct routing of the alternator main power 
cable by following steps 1.5. through 1.9. of the Instructions in 
Mooney International Corporation Service Bulletin M20-340C, dated 
February 14, 2020.

(h) Special Flight Permit

    A special flight permit may be issued with the following 
limitations:
    (1) Flights must not carry passengers;
    (2) Operation in daytime visual meteorological conditions only;
    (3) Straight and level flight must be maintained;
    (4) Operation in areas of known turbulence prohibited; and
    (5) Altitude limited to 9,000 ft. above sea level.

(i) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Fort Worth 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.
