(Type Certificate Previously Held by Piaggio Aero Industries S.p.A.) Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Final rule. AGENCY: SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain Piaggio Aviation S.p.A. (type certificate previously held by Piaggio Aero Industries S.p.A.) (Piaggio) Model P–180 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 identifies the unsafe condition as corrosion in the bottom fuselage area of the cabin compartment due to inner and outer sides of fuselage skin panels of certain airplanes treated with the less effective primer. This AD requires repetitively inspecting the fuselage skin panels, visually inspecting the entire fuselage inner side skin if necessary, and taking any necessary corrective actions. The FAA is issuing this AD to address the unsafe condition on these products. This AD is effective December 23, 2022. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of December 23, 2022. ADDRESSES: AD Docket: You may examine the AD docket at regulations.gov under Docket No. FAA–2022–0599; or in person at Docket Operations between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

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 Piaggio Model P–180 airplanes. The NPRM published in the Federal Register on June 17, 2022 (87 FR 36415). The NPRM 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 EASA AD 2021–0104, dated April 15, 2021 (referred to after this as ‘‘the MCAI’’), to address the unsafe condition on certain serial-numbered Piaggio Model P.180 airplanes. The MCAI states: Occurrences were reported where, during routine inspections, diffused corrosion was detected on the fuselage inner side skin in the area of the passenger cabin. Evidence indicates that the presence of undetected (infiltrated or condensed) water, trapped in between the inner surface of fuselage skin panels and the thermo-acoustic insulation panels, could have started a galvanic corrosion phenomenon, mainly in the bottom fuselage area of the cabin compartment. Fuselage skin panels of certain aeroplanes, delivered from 2009 to 2013, were treated with the first type of ‘‘chromate-free’’ primer, chemically not as effective against corrosion when compared to those containing chrome. The phenomenon has been observed on aeroplanes subjected to prolonged inactivity and not stored in a hangar, or those operating in an environment with high humidity and/ or frequent heavy precipitation, combined with a possible deterioration of window sealing due to normal aging, wear and tear. This condition, if not corrected, could affect the structural integrity of the fuselage. To address this potential unsafe condition, Piaggio published the [Piaggio Service Bulletin (SB) 80–0405, Revision 0, dated March 15, 2021] SB to provide inspection instructions. For the reason described above, this [EASA] AD requires repetitive inspections of E:\FR\FM\18NOR1.SGM 18NOR1 Federal Register / Vol. 87, No. 222 / Friday, November 18, 2022 / Rules and Regulations each affected area and, if necessary, an additional visual inspection of the entire fuselage inner side skin and, depending on findings, accomplishment of applicable repair. This [EASA] AD also requires reporting the inspection results to Piaggio. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2022–0599. In the NPRM, the FAA proposed to require repetitively inspecting the fuselage skin panels, visually inspecting the entire fuselage inner side skin if necessary, and taking any necessary corrective actions. The FAA is issuing this AD to prevent degradation of the structural integrity of the fuselage. The unsafe condition, if not addressed, could lead to loss of control of the airplane. Discussion of Final Airworthiness Directive Comments The FAA received a comment from one individual commenter. The following presents the comment received on the NPRM and the FAA’s response to the comment. khammond on DSKJM1Z7X2PROD with RULES Request Not To Require Repetitive 26Month Inspection An individual commenter requested the FAA not require a 26-month repetitive inspection as proposed in the NPRM. The commenter stated that all U.S. operators follow the Piaggio P.180 Avanti II Maintenance Manual (MM) inspection program in which these areas are already being inspected every 5 years and 3,600 flight hours. The commenter also asserted that there could be patch repairs for previously inspected and repaired areas, and that, if patch repairs are found with no corrosion in previously inspected areas, no further action should be required. Therefore, the commenter believes implementing the 26-month repetitive inspection is excessive. The FAA partially agrees. The FAA does not agree that all U.S.-registered airplanes are required to comply with Chapter 5 of the MM, which is where the inspections referenced by the commenter are located. Owners and operators must only comply with the Airworthiness Limitations section of the MM (located in Chapter 4 of this MM), as well as 14 CFR part 43, unless the airplane is operated under 14 CFR part 135 and its operating specifications require it. In addition, if the fuselage panels affected by this AD are replaced as part of the corrective actions required by paragraph (g)(1) of this AD, the repetitive inspections in paragraph (g)(2)(ii) of this AD are not required. Corrosion found outside of the affected fuselage areas of this AD should be repaired; however, these repairs are not mandated by this AD. Only the fuselage areas defined in the referenced service bulletin are affected by this AD. If corrosion is found as a result of the inspections required by this AD, this would show that the primer coating is inadequate to protect the material from corrosion; therefore, the repetitive inspections in this AD are necessary. The EASA, as the state of design, determined that a repetitive inspection interval of not to exceed 660 hours timein-service (TIS) or 26 months, whichever occurs first, is appropriate. The FAA has no data to dispute this specified criteria concerning the timein-service or calendar-month inspection interval determination. The FAA does agree that if repairs were previously accomplished on the areas required to be inspected by this AD and no corrosion was found during the inspections required by paragraph (g)(1) of this AD, the repetitive inspections in paragraph (g)(2)(ii) of this AD are not required. The FAA has not changed this final rule as a result of this comment. 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, considered the comment received, and determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on this product. Except for updating this AD to reflect that the type certificate holder changed from Piaggio Aero Industries S.p.A. to Piaggio Aviation S.p.A and changing the term ‘‘fuselage wing skin panel’’ used in paragraph (g)(1) of the NPRM to ‘‘fuselage skin panel,’’ this AD is adopted as proposed in the NPRM. None of the changes increase the economic burden on any operator. Related Service Information Under 1 CFR Part 51 The FAA reviewed Piaggio SB 80– 0405, Revision 0, dated March 15, 2021. This service information specifies procedures for inspecting the fuselage skin panels and inspecting the full inner fuselage skin. It also specifies repairing or replacing any parts where corrosion is found. The FAA also reviewed Piaggio SB 80–0405, Revision 0, Errata Corrige No. 1, dated March 24, 2021, which addresses discrepancies identified in Piaggio SB 80–0405, Revision 0, dated March 15, 2021. 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. Differences Between This AD and the MCAI, Service Information, or NPRM The MCAI allows credit for the fuselage inner skin inspection if previously done using Piaggio Aviation S.p.A. Temporary Revision No. 332 to Chapter 53–00–00 of Piaggio P.180 Avanti II MM, and this AD does not. The FAA will consider requests for an alternative method of compliance for this under paragraph (h) of this AD. The MCAI specifies compliance times of 8 months and 12 months depending on when the P.180 Avanti II MM 3,600flight-hour or 5-year inspection was accomplished. This AD has a 12-month compliance time for all airplanes because the 3,600-flight-hour and 5-year MM inspections are not required for all U.S. operators by FAA regulation. The service information specifies contacting Piaggio for certain repair instructions, while this AD requires repair using a method approved by the FAA or EASA. Costs of Compliance The FAA estimates that this AD affects 14 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: ESTIMATED COSTS Action Inspections ............................. VerDate Sep<11>2014 15:59 Nov 17, 2022 Labor cost Parts cost Up to 150 work-hours × $85 per hour = $12,750.

Authority for This Rulemaking khammond on DSKJM1Z7X2PROD with RULES Cost per airplane Action 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.

SUPPLEMENTARY INFORMATION: SUMMARY: The FAA is adopting a new airworthiness directive (AD) for Bell Textron Canada Limited (type certificate previously held by Bell Helicopter Textron Canada Limited) Model 206L, 206L–1, 206L–3, and 206L–4 helicopters with a certain part-numbered main rotor (M/R) blade installed under Supplemental Type Certificate (STC) SR02684LA. This AD was prompted by delamination of M/R blades. This AD requires a repetitive inspection for delamination, and depending on the results, removing the M/R blade from service and reporting certain information. The FAA is issuing this AD to address the unsafe condition on these products. Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to Bell Textron Canada Limited Model 206L, 206L–1, 206L–3, and 206L–4 helicopters with a certain partnumbered M/R blade installed under STC SR02684LA. The NPRM published in the Federal Register on March 24, 2022 (87 FR 16652). The NPRM was prompted by testing by Van Horn Aviation, LLC (Van Horn), which revealed the potential for delamination in M/R blade part number (P/N) 20633000–101. Delaminations were then confirmed by inspection of inservice M/R blades. Testing by Van Horn confirmed that the 90° plies fail in spanwise tension (normal to the fiber [FR Doc. 2022–25029 Filed 11–17–22; 8:45 am] BILLING CODE 4910–13–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2022–0286; Project Identifier AD–2021–01081–R; Amendment 39–22223; AD 2022–22–08] RIN 2120–AA64 Airworthiness Directives; Bell Textron Canada Limited (Type Certificate Previously Held by Bell Helicopter Textron Canada Limited) Helicopters Federal Aviation Administration (FAA), DOT.

Airworthiness Directives; Piaggio Aviation S.p.A. (Type 
Certificate Previously Held by Piaggio Aero Industries S.p.A.) 
Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Piaggio Aviation S.p.A. (type certificate previously held by 
Piaggio Aero Industries S.p.A.) (Piaggio) Model P-180 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 identifies the unsafe condition as corrosion in the bottom 
fuselage area of the cabin compartment due to inner and outer sides of 
fuselage skin panels of certain airplanes treated with the less 
effective primer. This AD requires repetitively inspecting the fuselage 
skin panels, visually inspecting the entire fuselage inner side skin if 
necessary, and taking any necessary corrective actions. The FAA is 
issuing this AD to address the unsafe condition on these products.

DATES: This AD is effective December 23, 2022.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of December 23, 
2022.

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 
Piaggio Model P-180 airplanes. The NPRM published in the Federal 
Register on June 17, 2022 (87 FR 36415). The NPRM 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 EASA AD 2021-0104, dated April 15, 2021 (referred to after 
this as ``the MCAI''), to address the unsafe condition on certain 
serial-numbered Piaggio Model P.180 airplanes. The MCAI states:

    Occurrences were reported where, during routine inspections, 
diffused corrosion was detected on the fuselage inner side skin in 
the area of the passenger cabin. Evidence indicates that the 
presence of undetected (infiltrated or condensed) water, trapped in 
between the inner surface of fuselage skin panels and the thermo-
acoustic insulation panels, could have started a galvanic corrosion 
phenomenon, mainly in the bottom fuselage area of the cabin 
compartment. Fuselage skin panels of certain aeroplanes, delivered 
from 2009 to 2013, were treated with the first type of ``chromate-
free'' primer, chemically not as effective against corrosion when 
compared to those containing chrome. The phenomenon has been 
observed on aeroplanes subjected to prolonged inactivity and not 
stored in a hangar, or those operating in an environment with high 
humidity and/or frequent heavy precipitation, combined with a 
possible deterioration of window sealing due to normal aging, wear 
and tear.
    This condition, if not corrected, could affect the structural 
integrity of the fuselage.
    To address this potential unsafe condition, Piaggio published 
the [Piaggio Service Bulletin (SB) 80-0405, Revision 0, dated March 
15, 2021] SB to provide inspection instructions.
    For the reason described above, this [EASA] AD requires 
repetitive inspections of

[[Page 69159]]

each affected area and, if necessary, an additional visual 
inspection of the entire fuselage inner side skin and, depending on 
findings, accomplishment of applicable repair. This [EASA] AD also 
requires reporting the inspection results to Piaggio.

    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2022-0599.
    In the NPRM, the FAA proposed to require repetitively inspecting 
the fuselage skin panels, visually inspecting the entire fuselage inner 
side skin if necessary, and taking any necessary corrective actions. 
The FAA is issuing this AD to prevent degradation of the structural 
integrity of the fuselage. The unsafe condition, if not addressed, 
could lead to loss of control of the airplane.

Discussion of Final Airworthiness Directive

Comments

    The FAA received a comment from one individual commenter. The 
following presents the comment received on the NPRM and the FAA's 
response to the comment.

Request Not To Require Repetitive 26-Month Inspection

    An individual commenter requested the FAA not require a 26-month 
repetitive inspection as proposed in the NPRM. The commenter stated 
that all U.S. operators follow the Piaggio P.180 Avanti II Maintenance 
Manual (MM) inspection program in which these areas are already being 
inspected every 5 years and 3,600 flight hours. The commenter also 
asserted that there could be patch repairs for previously inspected and 
repaired areas, and that, if patch repairs are found with no corrosion 
in previously inspected areas, no further action should be required. 
Therefore, the commenter believes implementing the 26-month repetitive 
inspection is excessive.
    The FAA partially agrees. The FAA does not agree that all U.S.-
registered airplanes are required to comply with Chapter 5 of the MM, 
which is where the inspections referenced by the commenter are located. 
Owners and operators must only comply with the Airworthiness 
Limitations section of the MM (located in Chapter 4 of this MM), as 
well as 14 CFR part 43, unless the airplane is operated under 14 CFR 
part 135 and its operating specifications require it. In addition, if 
the fuselage panels affected by this AD are replaced as part of the 
corrective actions required by paragraph (g)(1) of this AD, the 
repetitive inspections in paragraph (g)(2)(ii) of this AD are not 
required. Corrosion found outside of the affected fuselage areas of 
this AD should be repaired; however, these repairs are not mandated by 
this AD. Only the fuselage areas defined in the referenced service 
bulletin are affected by this AD. If corrosion is found as a result of 
the inspections required by this AD, this would show that the primer 
coating is inadequate to protect the material from corrosion; 
therefore, the repetitive inspections in this AD are necessary. The 
EASA, as the state of design, determined that a repetitive inspection 
interval of not to exceed 660 hours time-in-service (TIS) or 26 months, 
whichever occurs first, is appropriate. The FAA has no data to dispute 
this specified criteria concerning the time-in-service or calendar-
month inspection interval determination. The FAA does agree that if 
repairs were previously accomplished on the areas required to be 
inspected by this AD and no corrosion was found during the inspections 
required by paragraph (g)(1) of this AD, the repetitive inspections in 
paragraph (g)(2)(ii) of this AD are not required. The FAA has not 
changed this final rule as a result of this comment.

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, considered the 
comment received, and determined that air safety requires adopting this 
AD as proposed. Accordingly, the FAA is issuing this AD to address the 
unsafe condition on this product. Except for updating this AD to 
reflect that the type certificate holder changed from Piaggio Aero 
Industries S.p.A. to Piaggio Aviation S.p.A and changing the term 
``fuselage wing skin panel'' used in paragraph (g)(1) of the NPRM to 
``fuselage skin panel,'' this AD is adopted as proposed in the NPRM. 
None of the changes increase the economic burden on any operator.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Piaggio SB 80-0405, Revision 0, dated March 15, 
2021. This service information specifies procedures for inspecting the 
fuselage skin panels and inspecting the full inner fuselage skin. It 
also specifies repairing or replacing any parts where corrosion is 
found.
    The FAA also reviewed Piaggio SB 80-0405, Revision 0, Errata 
Corrige No. 1, dated March 24, 2021, which addresses discrepancies 
identified in Piaggio SB 80-0405, Revision 0, dated March 15, 2021.
    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.

Differences Between This AD and the MCAI, Service Information, or NPRM

    The MCAI allows credit for the fuselage inner skin inspection if 
previously done using Piaggio Aviation S.p.A. Temporary Revision No. 
332 to Chapter 53-00-00 of Piaggio P.180 Avanti II MM, and this AD does 
not. The FAA will consider requests for an alternative method of 
compliance for this under paragraph (h) of this AD.
    The MCAI specifies compliance times of 8 months and 12 months 
depending on when the P.180 Avanti II MM 3,600-flight-hour or 5-year 
inspection was accomplished. This AD has a 12-month compliance time for 
all airplanes because the 3,600-flight-hour and 5-year MM inspections 
are not required for all U.S. operators by FAA regulation.
    The service information specifies contacting Piaggio for certain 
repair instructions, while this AD requires repair using a method 
approved by the FAA or EASA.

Costs of Compliance

    The FAA estimates that this AD affects 14 airplanes of U.S. 
registry.
    The FAA estimates the following costs to comply with this AD:

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.
