Submissions containing CBI should be sent to Doug Rudolph, Aerospace Engineer, FAA, General Aviation & Rotorcraft Section, International Validation Branch, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329– 4059; fax: (816) 329–4090; email: doug.rudolph@faa.gov. Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Discussion The European Union Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union Community, has issued EASA AD No. 2020–0158, dated July 16, 2020 (referred to after this as ‘‘the VerDate Sep<11>2014 16:42 Sep 16, 2020 Jkt 250001 MCAI’’), to address an unsafe condition on certain Pilatus Aircraft Ltd. (Pilatus) Model PC–24 airplanes. The MCAI states: During production, electrical harness installations on some PC–24 aeroplanes were found not to comply with the approved design. This condition, if not corrected, could lead to wire chafing and potential arcing, or to failure of wires having the incorrect length, possibly resulting in loss of system redundancy, or generation of smoke and smell, or loss of power plant fire protection function. To address this potential unsafe condition, Pilatus issued the [service bulletin] SB, providing instructions to improve the electrical harness installations in the nose bay, cockpit, fuselage, wing fairing and rear fuselage areas. For the reason described above, this [EASA] AD requires modification of the electrical harness installations. The incorrect length wires are too short in length and do not have appropriate slack, which could lead to wires being pulled loose from the terminals during flight or ground operation. Generation of smell refers to the smell from electrical arcing. You may obtain further information by examining the MCAI in the AD docket on the internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2020– 0818. Related Service Information Under 1 CFR Part 51 The FAA reviewed Pilatus PC–24 Service Bulletin No. 91–001, dated April 7, 2020. The service information specifies procedures necessary to improve the electrical harness installation in the nose bay, cockpit, avionics rack, fuselage, wing fairing, and rear fuselage. 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 and Requirements of the Proposed AD This product has been approved by the aviation authority of another country and is approved for operation in the United States. Pursuant to our bilateral agreement with this State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI and service information referenced above. The FAA is proposing this AD because the FAA evaluated all information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. PO 00000 Frm 00006 Fmt 4702 Sfmt 4702 58003 Costs of Compliance The FAA estimates that this proposed AD would affect ßNumber_of_Aircraft® products of U.S. registry. The FAA also estimates that it would take 20 workhours per product to comply with the requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost about ßInspect_Parts® per product. Based on these figures, the FAA estimates the cost of the proposed AD on U.S. operators would be ßFleet_ Cost®, or $1,775 per product. According to the manufacturer, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. The FAA does not control warranty coverage for affected individuals. As a result, the FAA has included all costs in this cost estimate. 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 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) 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 E:\FR\FM\17SEP1.SGM 17SEP1 58004 Federal Register / Vol. 85, No. 181 / Thursday, September 17, 2020 / Proposed Rules under the criteria of the Regulatory Flexibility Act.

Airworthiness Directives; Pilatus Aircraft Ltd.

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain Pilatus Aircraft Ltd. (Pilatus) Model PC-24 airplanes. This 
proposed AD results from mandatory continuing airworthiness information 
(MCAI) originated by an aviation authority of another country to 
identify and correct an unsafe condition on an aviation product. The 
MCAI identifies the unsafe condition as electrical harness 
installations on PC-24 airplanes that are not in compliance with the 
approved design. This unsafe condition could lead to wire chafing and 
potential arcing or failure of wires having the incorrect length, 
possibly resulting in loss of system redundancy, or generation of smoke 
and smell, or loss of power plant fire protection function. The FAA is 
proposing this AD to address the unsafe condition on these products.

DATES: The FAA must receive comments on this proposed AD by November 2, 
2020.

Discussion

    The European Union Aviation Safety Agency (EASA), which is the 
Technical Agent for the Member States of the European Union Community, 
has issued EASA AD No. 2020-0158, dated July 16, 2020 (referred to 
after this as ``the MCAI''), to address an unsafe condition on certain 
Pilatus Aircraft Ltd. (Pilatus) Model PC-24 airplanes. The MCAI states:

    During production, electrical harness installations on some PC-
24 aeroplanes were found not to comply with the approved design.
    This condition, if not corrected, could lead to wire chafing and 
potential arcing, or to failure of wires having the incorrect 
length, possibly resulting in loss of system redundancy, or 
generation of smoke and smell, or loss of power plant fire 
protection function.
    To address this potential unsafe condition, Pilatus issued the 
[service bulletin] SB, providing instructions to improve the 
electrical harness installations in the nose bay, cockpit, fuselage, 
wing fairing and rear fuselage areas.
    For the reason described above, this [EASA] AD requires 
modification of the electrical harness installations.

    The incorrect length wires are too short in length and do not have 
appropriate slack, which could lead to wires being pulled loose from 
the terminals during flight or ground operation. Generation of smell 
refers to the smell from electrical arcing.
    You may obtain further information by examining the MCAI in the AD 
docket on the internet at https://www.regulations.gov by searching for 
and locating Docket No. FAA-2020-0818.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Pilatus PC-24 Service Bulletin No. 91-001, dated 
April 7, 2020. The service information specifies procedures necessary 
to improve the electrical harness installation in the nose bay, 
cockpit, avionics rack, fuselage, wing fairing, and rear fuselage. 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 and Requirements of the Proposed AD

    This product has been approved by the aviation authority of another 
country and is approved for operation in the United States. Pursuant to 
our bilateral agreement with this State of Design Authority, it has 
notified the FAA of the unsafe condition described in the MCAI and 
service information referenced above. The FAA is proposing this AD 
because the FAA evaluated all information and determined the unsafe 
condition exists and is likely to exist or develop on other products of 
the same type design.

Costs of Compliance

    The FAA estimates that this proposed AD would affect 
[Lt]Number_of_Aircraft[Gt] products of U.S. registry. The FAA also 
estimates that it would take 20 work-hours per product to comply with 
the requirements of this proposed AD. The average labor rate is $85 per 
work-hour. Required parts would cost about [Lt]Inspect_Parts[Gt] per 
product.
    Based on these figures, the FAA estimates the cost of the proposed 
AD on U.S. operators would be [Lt]Fleet_Cost[Gt], or $1,775 per 
product.
    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. The FAA does not control warranty coverage for affected 
individuals. As a result, the FAA has included all costs in this cost 
estimate.

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

    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) 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
