Abstract
The FAA is adopting a new airworthiness directive (AD) for certain Pilatus Aircraft Ltd. (Pilatus) Model PC-24 airplanes. 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. This AD requires 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.

the unsafe condition as insufficient performance of the fuel drain
system that could lead to fire and damage of the airplane. This AD
requires 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.

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 <a href="https://www.regulations.gov">https://www.regulations.gov</a> 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:

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:

FAA-2021-0218; Project Identifier MCAI-2020-01519-A.
(a) Effective Date
This airworthiness directive (AD) is effective February 25,
2022.

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.
