AD 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. This AD requires 

inspecting the alternator main power 

cable and the exhaust crossover tube for 

damage, replacing damaged parts as 

necessary, and installing an additional 

alternator cable clamp. The FAA is 

issuing this AD to address the unsafe 

condition on these products. 

DATES: This AD is effective July 7, 2021. 

The Director of the Federal Register

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain serial-numbered 

Mooney Model M20V airplanes. The 

NPRM published in the Federal 

Register on March 9, 2021 (86 FR 13502; 

corrected March 17, 2021, 86 FR 14554). 

The NPRM was prompted by reports of 

short circuit and 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). In the NPRM, the FAA 

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 (P/N) 

MS21919WCJ6. 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. The FAA is issuing this AD 

to address the unsafe condition on these 

products. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received no comments on 

the NPRM or on the determination of 

the costs. 

Conclusion 

The FAA reviewed the relevant data 

and determined that air safety requires 

adopting this AD as proposed. 

Accordingly, the FAA is issuing this AD 

to address the unsafe condition on these 

products. This AD is adopted as 

proposed in the NPRM. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Mooney 

International Corporation Service 

Bulletin M20–340C, dated February 14, 

2020. 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, P/N MS21919WCJ6.

Federal Register / Vol. 86, No. 104 / Wednesday, June 2, 2021 / Rules and Regulations 29487 

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 ADDRESSES. 

Costs of Compliance 

The FAA estimates that this AD 

affects 18 airplanes of U.S. registry. 

The FAA estimates the following 

costs to comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Inspect the cable and exhaust crossover tube 

for damage.

.5 work-hour × $85 per hour = $42.50 ........... $0 $42.50 $765 

Install additional cable clamp .......................... .5 work-hour × $85 per hour = $42.50 ........... 10 52.50 945 

The FAA estimates the following 

costs to do any necessary replacements 

that would be required based on the 

results of the inspection. The agency has 

no way of determining the number of 

airplanes that might need these 

replacements: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Replace alternator main power cable .......................... 8 work-hours × $85 per hour = $680 ........................... $1,000 $1,680 

Replace exhaust crossover tube .................................. 8 work-hours × $85 per hour = $680 ........................... 2,500 3,180 

The FAA has included all known 

costs in its cost estimate. According to 

the manufacturer, however, some of the 

costs of this 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 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 

This AD will not have federalism 

implications under Executive Order 

13132. This AD will 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 that this AD: 

(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.

SUPPLEMENTARY INFORMATION:

Authority for This Rulemaking 

The FAA’s authority to issue rules 

regarding aviation safety is found in 

Title 49 of the United States Code. 

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. This rulemaking is 

promulgated under the authority 

described in Subtitle VII, Part A, 

Subpart I, Section 40103. Under that 

section, the FAA is charged with 

prescribing regulations to assign the use 

of the airspace necessary to ensure the 

safety of aircraft and the efficient use of 

airspace. This regulation is within the 

scope of that authority as it improves 

the efficiency of the NAS by lessening 

the dependency on ground-based 

navigation aids. 

History 

The FAA published a notice of 

proposed rulemaking for Docket No. 

FAA–2021–0062 in the Federal Register 

(86 FR 12866; March 5, 2021) amending 

low altitude RNAV route T–207 by 

removing the Cecil, FL, VOR from the 

route description. Interested parties 

were invited to participate in this 

rulemaking effort by submitting written 

comments on the proposal. No 

comments were received. 

United States Area Navigation routes 

are published in paragraph 6011 of FAA 

Order 7400.11E, dated July 21, 2020, 

and effective September 15, 2020, which 

is incorporated by reference in 14 CFR 

71.1. The RNAV route listed in the 

document will be subsequently 

published in the Order. 

Availability and Summary of 

Documents for Incorporation by 

Reference 

This document amends FAA Order 

7400.11E, Airspace Designations and 

Reporting Points, dated July 21, 2020, 

and effective September 15, 2020. FAA 

Order 7400.11E is publicly available as 

listed in the ADDRESSES section of this 

document. FAA Order 7400.11E lists 

Class A, B, C, D, and E airspace areas, 

air traffic service routes, and reporting 

points. 

The Rule 

This action amends 14 CFR part 71 by 

amending low altitude RNAV route 

T–207 by removing the Cecil, FL (VQQ), 

VOR from the route description. This 

action is necessary due to the planned 

decommissioning of the Cecil VOR. The 

Cecil VOR is located along a straight 

segment of T–207 between the CARRA, 

FL, Fix, and the MONIA, FL, Fix. The 

VOR is not a required component for 

navigating on T–207. Removal of the 

Cecil VOR does not affect the alignment 

of, or navigation along, T–207.
