SUPPLEMENTARY INFORMATION: may examine the MCAI on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA–2019–0412. Discussion The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Piaggio Aero Industries S.p.A. Model P–180 airplanes. The NPRM published in the Federal Register on June 5, 2019 (84 FR 26025). The NPRM proposed to correct an unsafe condition for the specified products and was based on mandatory continuing airworthiness information (MCAI) originated by the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union. EASA issued AD No. 2017–0229, dated November 21, 2017 (referred to after this as ‘‘the MCAI’’), which states: Related Service Information Under 1 CFR Part 51 An occurrence was reported of finding insufficient sealing of a Steering Select/ Bypass Valve installed on the nose landing gear (NLG) Steering Manifold of a P.180 aeroplane. This condition, if not detected and corrected, could lead to uncommanded deflection of the NLG wheel, possibly resulting in reduced control of the aeroplane on the ground, with consequent damage to the aeroplane and injury to occupants. To address this potential unsafe condition, PAI issued Service Bulletin (SB) 80–0325 to provide inspection and rectification instructions. For the reason described above, this [EASA] AD requires a leak test of the NLG Steering Manifold and, depending on the finding(s), accomplishment of applicable corrective action(s). This [EASA] AD also requires amendment of the applicable Aircraft Flight Manual (AFM). The MCAI further notes that airplanes with NLG steering manifold part number 72608 installed are known to include manufacturing serial numbers 1001, 3001, 3003, 3004, 3006, 3007, and 3008, and also include airplanes that have incorporated Piaggio Aerospace Service Bulletin No. 80–0425, Revision 0, dated March 30, 2017, and Piaggio Aerospace Service Bulletin No. 80– 0454, Revision 0, March 6, 2017. You PO 00000 Frm 00014 Fmt 4700 Sfmt 4700 Comments The FAA gave the public the opportunity to participate in developing this final rule. No comments were received 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 FAA reviewed Piaggio Aerospace Service Bulletin No. 80–0325, Revision 0, dated August 10, 2017 (SB 80–0325), and Piaggio Aerospace P.180 AVANTI II/EVO Temporary Change No. 89, dated August 30, 2017 (Temporary Change 89), to the airplane flight manual (AFM). SB 80–0325 contains procedures for doing a NLG steering manifold leakage test. Temporary Change 89 contains emergency operating procedures for the pilot to follow if the NLG steering system fails. 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. Other Related Service Information The FAA reviewed Piaggio Aerospace Service Bulletin No. 80–0425, Revision 0, dated March 30, 2017 (SB 80–0425); Piaggio Aerospace Service Bulletin No. 80–0454, Revision 0, March 6, 2017 (SB 80–0454); and Temporary Change No. 89 Errata Corrige, dated December 20, 2017 (Temporary Change 89EC). SB 80– 0425 and SB 80–0454 both contain procedures for replacing the main landing gear and the NLG steering system on the applicable airplanes. Temporary Change 89EC revises the cover page of Temporary Change 89 to clarify the applicability of the change. Costs of Compliance The FAA estimates that this AD will affect 130 products of U.S. registry. The FAA also estimates that it will take about 2.5 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Based on these figures, the FAA estimates the cost of this AD on U.S. operators to be $27,625, or $212.50 per product. E:\FR\FM\29SER1.SGM 29SER1 Federal Register / Vol. 85, No. 189 / Tuesday, September 29, 2020 / Rules and Regulations If necessary, the FAA estimates that replacing a NLG steering manifold would take about 10 work-hours and require parts costing $50,058, for a cost of $50,908 per product. The FAA has no way of determining the number of products that may need these actions. ■ 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 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. List of Subjects in 14 CFR Part 39 jbell on DSKJLSW7X2PROD with RULES Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: VerDate Sep<11>2014 15:52 Sep 28, 2020 Jkt 250001 PART 39—AIRWORTHINESS DIRECTIVES 1.

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 certain GE GEnx–1B64/P2, –1B67/P2, –1B70/P2, –1B70C/P2, –1B70/75/P2, –1B74/75/P2, –1B76/P2, –1B76A/P2, and GEnx–2B67/P model turbofan engines. The NPRM published in the Federal Register on June 8, 2020 (85 FR 35021). The NPRM was prompted by the detection of meltrelated freckles in the billet, which may reduce the life limits of certain HPT rotor stage 2 disks and a certain stages 6–10 compressor rotor spool. The NPRM proposed to require the removal of certain HPT rotor stage 2 disk and the removal of a certain stages 6–10 compressor rotor spool before reaching their new life limits. The FAA is issuing this AD to address the unsafe condition on these products. Comments The FAA gave the public the opportunity to participate in developing this final rule. The following presents the comments received on the NPRM and the FAA’s response to each comment. Request to List Part and Serial Numbers GE requested that both the affected part and serial numbers be listed in the Applicability section of this AD instead of the affected engine serial numbers. The FAA agrees. The FAA recognizes that affected HPT rotor stage 2 disks could be moved from one engine to another engine. The intent of this AD is to mandate the removal of the affected PO 00000 Frm 00016 Fmt 4700 Sfmt 4700 parts from service, regardless of the engine on which they are installed. The FAA is revising the Applicability section of this AD as suggested by the commenter. This change does not expand the scope of this AD because the number of affected engines installed on airplanes of U.S. registry remains the same in this final rule compared to what was published in the NPRM. Support for the AD The Air Line Pilots Association, International; the Boeing Company; and United Airlines Engineering expressed support for the AD as written. Conclusion The FAA reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this final rule with the changes described previously and minor editorial changes. The FAA has determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM. The FAA also determined that these changes will not increase the economic burden on any operator or increase the scope of this final rule. Related Service Information The FAA reviewed GE GEnx–1B Service Bulletin (SB) 72–0473 R00, dated April 14, 2020; GE GEnx–1B SB 72–0474 R00, dated April 14, 2020; and GE GEnx–2B SB 72–0416 R00, dated April 14, 2020. GE GEnx–1B SB 72– 0473 R00 describes procedures for removing and replacing the HPT rotor stage 2 disks on GE GEnx–1B model engines. GE GEnx–1B SB 72–0474 R00 describes procedures for removing and replacing the stages 6–10 compressor rotor spool on GE GEnx–1B model engines. GE GEnx–2B SB 72–0416 R00 describes procedures for removing and replacing the HPT rotor stage 2 disks on GE GEnx–2B model engines. Costs of Compliance The FAA estimates that this AD affects two engines installed on airplanes of U.S. registry; one engine requires the HPT rotor stage 2 disk replacement and one engine requires the stages 6–10 compressor rotor spool replacement.

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 all Piaggio Aero 
Industries S.p.A. Model P-180 airplanes. The NPRM published in the 
Federal Register on June 5, 2019 (84 FR 26025). The NPRM proposed to 
correct an unsafe condition for the specified products and was based on 
mandatory continuing airworthiness information (MCAI) originated by the 
European Aviation Safety Agency (EASA), which is the Technical Agent 
for the Member States of the European Union. EASA issued AD No. 2017-
0229, dated November 21, 2017 (referred to after this as ``the MCAI''), 
which states:

    An occurrence was reported of finding insufficient sealing of a 
Steering Select/Bypass Valve installed on the nose landing gear 
(NLG) Steering Manifold of a P.180 aeroplane.
    This condition, if not detected and corrected, could lead to 
uncommanded deflection of the NLG wheel, possibly resulting in 
reduced control of the aeroplane on the ground, with consequent 
damage to the aeroplane and injury to occupants.
    To address this potential unsafe condition, PAI issued Service 
Bulletin (SB) 80-0325 to provide inspection and rectification 
instructions.
    For the reason described above, this [EASA] AD requires a leak 
test of the NLG Steering Manifold and, depending on the finding(s), 
accomplishment of applicable corrective action(s). This [EASA] AD 
also requires amendment of the applicable Aircraft Flight Manual 
(AFM).

    The MCAI further notes that airplanes with NLG steering manifold 
part number 72608 installed are known to include manufacturing serial 
numbers 1001, 3001, 3003, 3004, 3006, 3007, and 3008, and also include 
airplanes that have incorporated Piaggio Aerospace Service Bulletin No. 
80-0425, Revision 0, dated March 30, 2017, and Piaggio Aerospace 
Service Bulletin No. 80-0454, Revision 0, March 6, 2017. You may 
examine the MCAI on the internet at https://www.regulations.gov by 
searching for and locating Docket No. FAA-2019-0412.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. No comments were received 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.

    If necessary, the FAA estimates that replacing a NLG steering 
manifold would take about 10 work-hours and require parts costing 
$50,058, for a cost of $50,908 per product. The FAA has no way of 
determining the number of products that may need these actions.

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 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.

reference, Safety.

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 (AD):

2020-19-10 Piaggio Aero Industries S.p.A.: Amendment 39-21253; 
Docket No. FAA-2019-0412; Product Identifier 2018-CE-030-AD.

(a) Effective Date

    This AD is effective November 3, 2020.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Piaggio Aero Industries S.p.A. Model P-180 
airplanes, certificated in any category.

(d) Subject

    Air Transport Association of America (ATA) Code 32: Landing 
Gear.

(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 
sealing of a steering select/bypass valve installed in the nose 
landing gear (NLG) manifold. The FAA is issuing this AD to detect 
and correct insufficient sealing of the steering select/bypass valve 
in the NLG steering manifold, which could lead to un-commanded NLG 
wheel turns with consequent lateral runway departure.

(f) Actions and Compliance

    Unless already done, do the following actions in paragraphs 
(f)(1) through (3) of this AD.
    (1) For airplanes with NLG steering manifold part number (P/N) 
72608 installed: (i) Within 50 hours time-in service after the 
effective date of this AD, do a steering manifold pressure leakage 
test and, if there is steering actuator movement during the test, 
replace the NLG steering manifold and repeat the test by following 
the Accomplishment Instructions, procedure steps (1) through (24), 
in Piaggio Aerospace Service Bulletin No. 80-0325, Revision 0, dated 
August 10, 2017.
    (ii) If steering actuator movement occurs during procedure step 
(9) or procedure step (15) of the leakage test required in paragraph 
(f)(1)(i) of this AD, replacing the NLG steering manifold and 
repeating the steering manifold pressure leakage test is required 
before further flight.
    (2) For all airplanes, after the effective date of this AD, do 
not install NLG steering manifold P/N 72608 on any airplane unless 
it has been inspected as specified in paragraph (f)(1) of this AD 
and no steering actuator movement occurred.
    (3) For all airplanes, within 30 days after the effective date 
of this AD, revise the airplane flight manual (AFM) by replacing 
certain pages in the Emergency Procedures section of the AFM by 
following the Instructions in Piaggio Aerospace P.180 AVANTI II/EVO 
Temporary Change No. 89, dated August 30, 2017.
