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 Pilatus Model PC–24 airplanes. The NPRM published in the Federal Register on October 8, 2021 (86 FR 56227). The NPRM was based on MCAI from the European Union Aviation Safety Agency E:\FR\FM\21JAR1.SGM 21JAR1 Federal Register / Vol. 87, No. 14 / Friday, January 21, 2022 / Rules and Regulations (EASA), which is the Technical Agent for the Member States of the European Union. EASA issued AD 2020–0252, dated November 12, 2020 (referred to after this as ‘‘the MCAI’’) to address the unsafe condition on these products. The MCAI states: An occurrence was reported where an insufficient performance of the fuel drain system was detected on certain PC–24 aeroplanes. This condition, if not corrected, could lead, in case of a fuel leak, to contamination of the inboard rear fuselage, creating a fuel vapour which, in combination with an ignition source, could possibly result in a fire and consequent damage to the aeroplane. To address this potential unsafe condition, Pilatus Aircraft issued the [service bulletin] SB providing instructions to modify the fuel drain pipe routing and to install a drain mast. For the reason described above, this [EASA] AD requires modification of the fuel drain system. In the NPRM, the FAA proposed to require modifying the fuel drain pipe routing and installing a drain mast. The FAA is issuing this AD to address the unsafe condition on these products. You may examine the MCAI in the AD docket at https:// www.regulations.gov by searching for and locating Docket No. FAA–2021– 0218. Comments The FAA received no comments on the NPRM or on the determination of the costs. jspears on DSK121TN23PROD with RULES1 Conclusion This product has been approved by the aviation authority of another country and is approved for operation in the United States. Pursuant to the FAA’s bilateral agreement with this State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI referenced above. 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 Pilatus PC–24 Service Bulletin No. 28–003, Revision 1, dated January 23, 2020. This service information specifies procedures for modifying the fuel drain pipe routing and installing a drain mast. 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. VerDate Sep<11>2014 16:23 Jan 20, 2022 Jkt 256001 3189 Costs of Compliance List of Subjects in 14 CFR Part 39 The FAA estimates that this AD will affect 36 airplanes of U.S. registry. The FAA also estimates that it would take about 12 work-hours per airplane to do the modification and installation of this AD. The average labor rate is $85 per work-hour. Required parts would cost about $1,950 per airplane. Based on these figures, the FAA estimates the cost of this AD on U.S. operators would be $106,920 or $2,970 per airplane. 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. Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. 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 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:

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 
Pilatus Model PC-24 airplanes. The NPRM published in the Federal 
Register on October 8, 2021 (86 FR 56227). The NPRM was based on MCAI 
from the European Union Aviation Safety Agency

[[Page 3189]]

(EASA), which is the Technical Agent for the Member States of the 
European Union. EASA issued AD 2020-0252, dated November 12, 2020 
(referred to after this as ``the MCAI'') to address the unsafe 
condition on these products. The MCAI states:

    An occurrence was reported where an insufficient performance of 
the fuel drain system was detected on certain PC-24 aeroplanes.
    This condition, if not corrected, could lead, in case of a fuel 
leak, to contamination of the inboard rear fuselage, creating a fuel 
vapour which, in combination with an ignition source, could possibly 
result in a fire and consequent damage to the aeroplane.
    To address this potential unsafe condition, Pilatus Aircraft 
issued the [service bulletin] SB providing instructions to modify 
the fuel drain pipe routing and to install a drain mast.
    For the reason described above, this [EASA] AD requires 
modification of the fuel drain system.

    In the NPRM, the FAA proposed to require modifying the fuel drain 
pipe routing and installing a drain mast. The FAA is issuing this AD to 
address the unsafe condition on these products.
    You may examine the MCAI in the AD docket at https://www.regulations.gov by searching for and locating Docket No. FAA-2021-
0218.

Comments

    The FAA received no comments on the NPRM or on the determination of 
the costs.

Conclusion

    This product has been approved by the aviation authority of another 
country and is approved for operation in the United States. Pursuant to 
the FAA's bilateral agreement with this State of Design Authority, it 
has notified the FAA of the unsafe condition described in the MCAI 
referenced above. 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 Pilatus PC-24 Service Bulletin No. 28-003, 
Revision 1, dated January 23, 2020. This service information specifies 
procedures for modifying the fuel drain pipe routing and installing a 
drain mast.
    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.

Costs of Compliance

    The FAA estimates that this AD will affect 36 airplanes of U.S. 
registry. The FAA also estimates that it would take about 12 work-hours 
per airplane to do the modification and installation of this AD. The 
average labor rate is $85 per work-hour. Required parts would cost 
about $1,950 per airplane.
    Based on these figures, the FAA estimates the cost of this AD on 
U.S. operators would be $106,920 or $2,970 per airplane.
    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 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.

The Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 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  [Amended]

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

2021-26-21 Pilatus Aircraft Ltd.: Amendment 39-21880; Docket No. 
FAA-2021-0218; Project Identifier MCAI-2020-01519-A.

(a) Effective Date

    This airworthiness directive (AD) is effective February 25, 
2022.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Pilatus Aircraft Ltd. Model PC-24 airplanes, 
serial numbers 101 through 184, certificated in any category.

(d) Subject

    Joint Aircraft System Component (JASC) Code 2830, Fuel Dump 
System.

(e) Reason

    This AD was prompted by 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 describes the unsafe condition as insufficient 
performance of the fuel drain system that could lead to fire and 
damage of the airplane. The FAA is issuing this AD to prevent fuel 
contamination of the inboard rear fuselage. If not addressed, this 
unsafe condition, in combination with an ignition source, could 
result in fire and loss of control of the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Required Actions

    Within 5 months after the effective date of this AD, modify the 
fuel drain pipe routing and install the drain mast by following 
paragraphs A. and B. of the Accomplishment Instructions in Pilatus 
PC-24 Service Bulletin No. 28-003, Revision 1, dated January 23, 
2020.
