The FAA estimates the following costs to do any necessary repairs/
replacements that would be required
Parts cost

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

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 FAAs 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 Agencys 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:

VerDate Sep<11>2014

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 39AIRWORTHINESS
DIRECTIVES
1. The authority citation for part 39
continues to read as follows:

Authority: 49 U.S.C. 106g, 40113, 44701.
39.13

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

Parts cost $1,000
2,500

Cost per product $1,680
3,180

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 M20340C, dated February 14, 2020.

b Affected ADs None.

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.

c Applicability This AD applies to Mooney International Corporation Model M20V airplanes, serial numbers 330001 through 330018, certificated in any category.

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
Mooney International Corporation: Docket No. FAA20200991; Project Identifier AD202000539A.
a Comments Due Date The FAA must receive comments on this airworthiness directive AD by April 23, 2021.
