Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Final rule. AGENCY: The FAA is adopting a new airworthiness directive (AD) for certain Pilatus Aircraft Ltd. (Pilatus) Model PC– 24 airplanes. This 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 movement of the aft fuel pipe within the coupling, which can cause damage to the O-rings and lead to a fuel leak, fuel fire or explosion, and consequent loss of control of the airplane. This AD requires replacing and prohibits installing affected parts. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective December 14, 2020. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of December 14, 2020. ADDRESSES: For service information identified in this final rule, contact Pilatus Aircraft Ltd., Customer Support General Aviation, CH–6371 Stans, Switzerland, telephone: +41 848 24 7 365, techsupport.ch@pilatusaircraft.com, https://www.pilatusaircraft.com. You may view this service information at the FAA, Airworthiness SUMMARY: PO 00000 Frm 00022 Fmt 4700 Sfmt 4700 Discussion The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to Pilatus Model PC–24 airplanes with a certain part-numbered flexible saddle clamp installed between frame 34 and 36. The NPRM published in the Federal Register on July 30, 2020 (85 FR 45810). The NPRM proposed to require actions to correct the unsafe condition on the specified products and was prompted by MCAI originated by the European Union Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union. EASA issued AD No. 2019–0240, dated September 25, 2019 (referred to after this as ‘‘the MCAI’’), which states: An occurrence was reported where, during maintenance, when system pressure was applied to a motive-flow fuel pipe, the aft fuel pipe was found to move to the end stop within the coupling. When system pressure was released, the aft fuel pipe returned to its point of origin. This movement can cause damage to the O-rings. This condition, if not corrected, could lead to a fuel leak and consequently a fuel contamination of the rear fuselage, which, in combination with an ignition source in this E:\FR\FM\09NOR1.SGM 09NOR1 Federal Register / Vol. 85, No. 217 / Monday, November 9, 2020 / Rules and Regulations area, could possibly result in a fuel fire or fuel vapour explosion and consequent loss of the aeroplane. To address this potential unsafe condition, Pilatus issued the [service bulletin] SB to provide modification instructions. For the reason described above, this [EASA] AD requires replacement of affected parts with serviceable parts, as defined in this AD, and prohibits (re-) installation of affected parts. You may examine the MCAI on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA–2020–0719. Comments The FAA gave the public the opportunity to participate in developing this final rule. The FAA received no comments on the NPRM or on the determination of the cost to the public. Conclusion The FAA reviewed the relevant data and determined that air safety and the public interest require adopting this final rule as proposed. khammond on DSKJM1Z7X2PROD with RULES Related Service Information Under 1 CFR Part 51 The FAA reviewed Pilatus PC–24 Service Bulletin No. 28–002, dated May 3, 2019. The service information contains procedures for replacing the two flexible saddle clamps on the lefthand (LH) motive-flow fuel pipe and the two flexible saddle clamps on the righthand (RH) motive-flow fuel pipe with fixed saddle clamps. This service information also contains procedures for replacing the four O-rings on the LH and RH motive-flow fuel pipes. 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 16 products of U.S. registry. The FAA also estimates that it will take about 7 work-hours per product to comply with the requirements of this AD. The average labor rate is $85 per work-hour. Required parts will cost about $5,000 per product. Based on these figures, the FAA estimates the cost of the AD on U.S. operators will be $89,520 or $5,595 per product. According to the manufacturer, all or 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. VerDate Sep<11>2014 15:57 Nov 06, 2020 Jkt 253001 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Pilatus Aircraft Ltd. (Pilatus) Model PC-24 airplanes. This 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 movement of the aft fuel pipe within the 
coupling, which can cause damage to the O-rings and lead to a fuel 
leak, fuel fire or explosion, and consequent loss of control of the 
airplane. This AD requires replacing and prohibits installing affected 
parts. The FAA is issuing this AD to address the unsafe condition on 
these products.

DATES: This AD is effective December 14, 2020.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of December 14, 
2020.

SUPPLEMENTARY INFORMATION:

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to Pilatus Model PC-24 
airplanes with a certain part-numbered flexible saddle clamp installed 
between frame 34 and 36. The NPRM published in the Federal Register on 
July 30, 2020 (85 FR 45810). The NPRM proposed to require actions to 
correct the unsafe condition on the specified products and was prompted 
by MCAI originated by the European Union Aviation Safety Agency (EASA), 
which is the Technical Agent for the Member States of the European 
Union. EASA issued AD No. 2019-0240, dated September 25, 2019 (referred 
to after this as ``the MCAI''), which states:

    An occurrence was reported where, during maintenance, when 
system pressure was applied to a motive-flow fuel pipe, the aft fuel 
pipe was found to move to the end stop within the coupling. When 
system pressure was released, the aft fuel pipe returned to its 
point of origin. This movement can cause damage to the O-rings.
    This condition, if not corrected, could lead to a fuel leak and 
consequently a fuel contamination of the rear fuselage, which, in 
combination with an ignition source in this

[[Page 71245]]

area, could possibly result in a fuel fire or fuel vapour explosion 
and consequent loss of the aeroplane.
    To address this potential unsafe condition, Pilatus issued the 
[service bulletin] SB to provide modification instructions.
    For the reason described above, this [EASA] AD requires 
replacement of affected parts with serviceable parts, as defined in 
this AD, and prohibits (re-) installation of affected parts.

    You may examine the MCAI on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2020-
0719.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The FAA received no comments on the NPRM or 
on the determination of the cost to the public.

Conclusion

    The FAA reviewed the relevant data and determined that air safety 
and the public interest require adopting this final rule as proposed.

the two flexible saddle clamps on the left-hand (LH) motive-flow fuel 
pipe and the two flexible saddle clamps on the right-hand (RH) motive-
flow fuel pipe with fixed saddle clamps. This service information also 
contains procedures for replacing the four O-rings on the LH and RH 
motive-flow fuel pipes. 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 16 products of U.S. 
registry. The FAA also estimates that it will take about 7 work-hours 
per product to comply with the requirements of this AD. The average 
labor rate is $85 per work-hour. Required parts will cost about $5,000 
per product.
    Based on these figures, the FAA estimates the cost of the AD on 
U.S. operators will be $89,520 or $5,595 per product.
    According to the manufacturer, all or 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

    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.

Adoption of 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:

2020-22-17 Pilatus Aircraft Ltd.: Amendment 39-21313; Docket No. 
FAA-2020-0719; Project Identifier 2019-CE-041-AD.

(a) Effective Date

    This airworthiness directive (AD) is effective December 14, 
2020.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Pilatus Aircraft Ltd. Model PC-24 airplanes, 
all serial numbers, certificated in any category, with a flexible 
saddle clamp part number (P/N) 946.33.22.004 installed between frame 
34 and 36.

(d) Subject

    Joint Aircraft System Component (JASC) Code 2800: Fuel.

(e) Reason

    This AD was prompted by an occurrence of movement of the aft 
fuel pipe within the coupling when system pressure was applied. This 
movement can cause damage to the O-rings, which could lead to a fuel 
leak and fuel contamination of the rear fuselage. The FAA is issuing 
this AD to prevent a fuel fire or fuel vapor explosion with 
consequent loss of airplane control.

(f) Actions and Compliance

    Unless already done, do the following actions in accordance with 
the applicable compliance times:
    (1) Within 3 months after the effective date of this AD, replace 
each flexible saddle clamp with a fixed saddle clamp with P/N 
946.33.21.933, align the left-hand (LH) and right-hand (RH) motive-
flow fuel pipes, and test the LH and RH motive-flow fuel pipe for 
leaks in accordance with the Accomplishment Instructions, sections 
3.B and 3.C, of Pilatus PC-24 Service Bulletin No. 28-002, dated May 
3, 2019.
    (2) As of the effective date of this AD, do not install a 
flexible saddle clamp with P/N 946.33.22.004 between frame 34 and 36 
on any airplane.

(g) Alternative Methods of Compliance (AMOCs)

    The Manager, International Validation Branch, FAA, has the 
authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19. Send information to Doug Rudolph,
