Abstract
The FAA is adopting a new airworthiness directive (AD) for certain Vulcanair S.p.A. Model V1.0 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 corrosion on the lower fuselage truss. This AD requires a detailed visual inspection of the right-hand (RH) and left-hand (LH) lower rear attachments of the fuselage truss for corrosion, a tactile inspection of the lower rear attachments for missing sealant, and a general visual inspection of the lower fuselage truss welded pipes for corrosion and the related rivets for missing stems and, depending on findings, additional inspections and actions (including a tap test) and applicable corrective actions. 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 Vulcanair
S.p.A. Model V1.0 airplanes. The NPRM published in the Federal Register
on June 27, 2023 (88 FR 41510). The NPRM was prompted by AD 2022-0155,
dated August 1, 2022 (referred to after this as the MCAI), issued by
the European Union Aviation Safety Agency (EASA), which is the
Technical Agent for the Member States of the European Union. The MCAI
states that there have been reports of corrosion on the lower fuselage
truss on two Vulcanair Model V1.0 airplanes. Missing sealant or missing
rivet stems were determined to be the root cause of corrosion by
allowing water ingress into the lower fuselage truss. In both reported
cases, corrosion was externally visible, having penetrated the
thickness of the pipes. However, corrosion could be present inside the
pipes and remain undetected without proper inspection. This condition,
if not detected and corrected, could result in loss of control of the
airplane.
In the NPRM, the FAA proposed to require a detailed visual
inspection of the RH and LH lower rear attachments of the fuselage
truss for corrosion, a tactile inspection of the lower rear attachments
for missing sealant, and a general visual inspection of the lower
fuselage truss welded pipes for corrosion and the related rivets for
missing stems and, depending on findings, additional inspections and
actions (including a tap test) and applicable corrective actions. The
FAA is issuing this AD to address the unsafe condition on these
products. The unsafe condition, if not addressed, could result in loss
of control of the airplane.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2023-1218.
Discussion of Final Airworthiness Directive
Comments
The FAA received no comments on the NPRM or on the determination of
the costs.
Conclusion
These products have been approved by the aviation authority of
another country and are 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 Vulcanair S.p.A. Service Bulletin No. VA-22,
Revision 0, dated June 15, 2022 (Vulcanair SB VA-22). This service
information specifies procedures for inspections of the lower fuselage
truss for corrosion, missing sealant, and missing rivet stems; and, in
case of findings, additional inspections and actions to detect
corrosion, including a tap test and raising the airplane nose. This
service information specifies to contact Vulcanair for corrective
actions.
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 ADDRESSES.
Differences Between This AD and the MCAI
Although Vulcanair SB VA-22, which is referenced in the MCAI,
specifies that ``in case of doubts, raise the aircraft nose and audibly
detect the presence of corrosion residues inside the fuselage truss,''
this AD does not require that action.
Paragraph (1) of the MCAI states to ``accomplish a general visual
and tactile inspection of the right-hand (RH) and left-hand (LH) lower
rear attachments of the fuselage truss'' in accordance with the
instructions of Part A of Vulcanair SB VA-22. However, step 14, Part A,
of Vulcanair SB VA-22 specifies to do a detailed visual inspection. In
email communication between EASA and the FAA, EASA clarified that this
should be a detailed visual inspection performed in accordance with the
procedures specified in Vulcanair SB VA-22; therefore, this AD requires
a detailed visual inspection of the RH and LH lower rear attachments of
the fuselage truss for corrosion.
The MCAI requires contacting the manufacturer for approved
corrective action instructions if any corrosion is found on the lower
fuselage truss. This AD requires contacting either the Manager,
International Validation Branch, FAA; or EASA; or Vulcanair's EASA
Design Organization Approval (DOA). If approved by the DOA, the
approval must include the DOA-authorized signature.
Costs of Compliance
The FAA estimates that this AD affects 17 airplanes of U.S.
registry.
The FAA estimates the following costs to comply with this AD:
[[Page 65124]]

The FAA estimates the following costs to do any necessary actions
that would be required based on the results of the required
inspections.

----------------------------------------------------------------------------------------------------------------
The corrective action instructions that may be needed as a result
of these inspections could vary significantly from airplane to
airplane. The FAA has no data to determine the costs to accomplish
those corrective actions or the number of airplanes that might need
these corrective 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.
