SUPPLEMENTARY INFORMATION: Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would Frm 00004 Fmt 4700 Sfmt 4700 Discussion of Final Airworthiness Directive Comments Examining the AD Docket PO 00000 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. 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.

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.

                                                 $680.
----------------------------------------------------------------------------------------------------------------

    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 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

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.

(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.
