Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain Piaggio Aero Industries S.p.A. (Piaggio) Model P-180 airplanes. This proposed 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 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 proposed AD would 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 proposing this AD to address the unsafe condition on these products.

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for certain Piaggio Aero Industries S.p.A. (Piaggio) Model P-180
airplanes. This proposed 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 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 proposed AD would 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 proposing this AD to address the unsafe
condition on these products.

Background
The European Union Aviation Safety Agency (EASA), which is the
Technical Agent for the Member States of the European Union, has 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 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 <a href="https://www.regulations.gov">https://www.regulations.gov</a> by searching for and locating Docket No. FAA-2022-
0599.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Piaggio SB No. 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 No. 80-0405, Revision 0, Errata
Corrige No. 1, dated March 24, 2021, which addresses discrepancies
identified in Piaggio SB No. 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.
FAA's Determination
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 and
service information referenced above. The FAA is issuing this NPRM
after determining the unsafe condition described previously is likely
to exist or develop on other products of the same type design.
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified
in the service information already described.
Differences Between This Proposed AD and the MCAI or Service
Information
The MCAI allows credit for the fuselage inner skin inspection if
previously done using Piaggio Aerospace Temporary Revision No. 332 to
Chapter 53-00-00 of Piaggio P.180
[[Page 36417]]
Avanti II Maintenance Manual, and this proposed AD would 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 airplane maintenance manual 3,600 flight
hour or 5-year inspection was accomplished. This proposed AD has a 12-
month compliance time for all airplanes because the 3,600 flight hour
and 5-year maintenance manual inspections are not required for U.S.
operators by FAA regulation.
The service information specifies contacting Piaggio for certain
repair instructions, while this proposed AD would require repair using
a method approved by the FAA or EASA.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 14 airplanes of U.S. registry.
The FAA estimates the following costs to comply with this proposed
AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Action Labor cost Parts cost Cost per airplane Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Inspections.................. Up to 150 work- $2,360 Up to $15,110.......... Up to $211,540.
hours x $85 per
hour = $12,750.
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary actions
that may be required based on the results of the proposed inspections.
The FAA has no way of estimating the number of airplanes that might
need these actions:
On-Condition Costs
----------------------------------------------------------------------------------------------------------------
Action Labor cost Parts cost Cost per airplane
----------------------------------------------------------------------------------------------------------------
Repair........................... Up to 80 work-hours $1,220...................... Up to $8,020.
x $85 per hour =
$6,800.
Replace skin panel............... Up to 250 work- Up to $12,200............... Up to $33,450.
hours x $85 per
hour = $21,250.
Reporting Results................ 1 work-hour x $85 Not Applicable.............. $1,190.
per hour = $85.
----------------------------------------------------------------------------------------------------------------
Paperwork Reduction Act
A federal agency may not conduct or sponsor, and a person is not
required to respond to, nor shall a person be subject to a penalty for
failure to comply with a collection of information subject to the
requirements of the Paperwork Reduction Act unless that collection of
information displays a currently valid OMB Control Number. The OMB
Control Number for this information collection is 2120-0056. Public
reporting for this collection of information is estimated to be
approximately 1 hour per response, including the time for reviewing
instructions, searching existing data sources, gathering and
maintaining the data needed, completing and reviewing the collection of
information. All responses to this collection of information are
mandatory. Send comments regarding this burden estimate or any other
aspect of this collection of information, including suggestions for
reducing this burden, to: Information Collection Clearance Officer,
Federal Aviation Administration, 10101 Hillwood Parkway, Fort Worth, TX
76177-1524.
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
The FAA determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 proposed
regulation:
(1) Is not be a ``significant regulatory action'' under Executive
Order 12866,
(2) Would not affect intrastate aviation in Alaska, and
(3) Would 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.
