Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: The FAA proposes to adopt a new airworthiness directive (AD) for certain Vulcanair S.p.A. Model V1.0 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 on the lower fuselage truss. This proposed AD would require 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 proposing this AD to address the unsafe condition on these products. SUMMARY: The FAA must receive comments on this NPRM by August 11, 2023.

The most helpful comments reference a specific portion of the proposal, explain the reason for any recommended change, and include supporting data. The FAA will consider all comments received by the closing date and may amend this proposal because of those comments. Except for Confidential Business Information (CBI) as described in the following paragraph, and other information as described in 14 CFR 11.35, the FAA will post all comments received, without change, to regulations.gov, including any personal information you provide. The agency will also post a report summarizing each substantive verbal contact received about this NPRM. Confidential Business Information CBI is commercial or financial information that is both customarily and actually treated as private by its owner. Under the Freedom of Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public disclosure. If your VerDate Sep<11>2014 17:46 Jun 26, 2023 Jkt 259001 comments responsive to this NPRM contain commercial or financial information that is customarily treated as private, that you actually treat as private, and that is relevant or responsive to this NPRM, it is important that you clearly designate the submitted comments as CBI. Please mark each page of your submission containing CBI as ‘‘PROPIN.’’ The FAA will treat such marked submissions as confidential under the FOIA, and they will not be placed in the public docket of this NPRM. Submissions containing CBI should be sent to John DeLuca, Aviation Safety Engineer, FAA, 1600 Stewart Avenue, Suite 410, Westbury, NY 11590. Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. 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 2022–0155, dated August 1, 2022 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition on certain serial-numbered Vulcanair S.p.A. Model V1.0 airplanes. The MCAI was prompted by 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. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2023–1218. Related Service Information Under 1 CFR Part 51 The FAA reviewed Vulcanair Aircraft V1 series Service Bulletin VA–22, rev. 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 PO 00000 Frm 00002 Fmt 4702 Sfmt 4702 41511 course of business or by the means identified in ADDRESSES. FAA’s Determination 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 and service information described 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 MCAI, except as discussed under ‘‘Differences Between this Proposed AD and the MCAI.’’ Differences Between This Proposed AD and the MCAI Although Vulcanair SB VA–22 specifies that ‘‘in case of doubts, raise the aircraft nose and audibly detect the presence of corrosion residues inside the fuselage truss,’’ this proposed AD would 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 proposed AD would require 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 proposed AD would require 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, if adopted as proposed, would affect 17 airplanes of U.S. registry. E:\FR\FM\27JNP1.SGM 27JNP1 41512 Federal Register / Vol. 88, No. 122 / Tuesday, June 27, 2023 / Proposed Rules The FAA estimates the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost Parts cost Cost per product Cost on U.S. operators Detailed visual inspection and tactile inspection of the RH and LH lower rear attachments, and a general visual inspection of the pipes. 8 work-hours × $85 per hour = $680 $0 $680 $11,560 Parts cost Cost per product The FAA estimates the following costs to do any necessary actions that would be required based on the results of the proposed inspections. ON-CONDITION COSTS Action Labor cost Remove sealant and detailed inspection of inner face of longitudinal tubes connected to lower rear attachments. Detailed visual inspection and tap test of the lower fuselage truss pipes. Installation of plug P/N 5034–011 on RH and LH lower rear attachments. 4 work-hours × $85 per hour = $340 .......... $0 $340 4 work-hours × $85 per hour = $340 .......... 0 340 0.50 work-hour × $85 per hour = $42.50 ... 130 172.50 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 would need these corrective actions. ddrumheller on DSK120RN23PROD with PROPOSALS1 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. 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 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. (a) Comments Due Date The FAA must receive comments on this airworthiness directive (AD) by August 11, 2023.

Airworthiness Directives; Vulcanair S.p.A. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain Vulcanair S.p.A. Model V1.0 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 on the lower fuselage truss. This 
proposed AD would require 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 proposing this AD to address the unsafe condition on these 
products.

specifically designated as CBI will be placed in the public docket for 
this rulemaking.

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 2022-0155, dated August 1, 2022 (referred to after this as 
``the MCAI''), to correct an unsafe condition on certain serial-
numbered Vulcanair S.p.A. Model V1.0 airplanes.
    The MCAI was prompted by 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.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2023-1218.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Vulcanair Aircraft V1 series Service Bulletin VA-
22, rev. 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.

FAA's Determination

    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 and service information described 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 MCAI, except as discussed under ``Differences Between this 
Proposed AD and the MCAI.''

Differences Between This Proposed AD and the MCAI

    Although Vulcanair SB VA-22 specifies that ``in case of doubts, 
raise the aircraft nose and audibly detect the presence of corrosion 
residues inside the fuselage truss,'' this proposed AD would 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 proposed AD 
would require 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 proposed AD would require 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, if adopted as proposed, would 
affect 17 airplanes of U.S. registry.

[[Page 41512]]

    The FAA estimates the following costs to comply with this proposed 
AD:

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

    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 would 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

    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 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.
