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 all Vulcanair S.p.A. Model P.68, P.68B, P.68C, P.68C-TC, P.68
"Observer," P.68TC "Observer," P.68 "Observer 2," and P.68R

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 2021-0267, dated November 24, 2021 (referred to after this as
"the MCAI"), to address an unsafe condition on Vulcanair S.p.A.
(Vulcanair) (formerly Partenavia Costruzioni Aeronautiche S.p.A.) Model
P.68 "Victor," P.68B "Victor," P.68R "Victor," P.68C, P.68C-TC,
P.68 "Observer," P.68 "Observer 2," and P.68TC "Observer"
airplanes, all serial numbers. The MCAI states:

Occurrences were reported of failures of the upper rudder hinge
on P.68 aeroplanes due to corrosion, which can occur if the
aeroplane is operated in an environment which may favour the
formation of corrosion.

This condition, if not detected and corrected, could interfere
with rudder movement and ultimately lead to failure, possibly
resulting in loss of control of the aeroplane.

To address this potential unsafe condition, Vulcanair issued the
SL [Vulcanair Aircraft Alert Service Letter No. 23, Revision 2,
dated September 29, 2021] and updated the applicable AMM [Aircraft
Maintenance Manual], as defined in this [EASA] AD, to provide
inspection instructions.

For the reason described above, this [EASA] AD requires
repetitive inspections of the upper and lower rudder hinges and,
depending on findings, accomplishment of applicable corrective
action(s).

You may examine the MCAI in the AD docket at https://www.regulations.gov
by searching for and locating Docket No. FAA-2022-0813.

Related Service Information Under 1 CFR Part 51


The FAA reviewed Vulcanair Aircraft Alert Service Letter No. 23,
Revision 2, dated September 29, 2021, which specifies procedures for
inspecting the upper and lower rudder hinges for corrosion, cracking,
and damage, and specifies contacting Vulcanair for instructions to
repair an affected rudder hinge. This service information also refers
to the applicable aircraft maintenance manuals for additional
inspection procedures.

The FAA also reviewed the following service information, which
specifies procedures for maintaining various structural parts. These
documents are distinct since they apply to different airplane models.

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, except as discussed under
"Differences Between this Proposed AD and the MCAI."

Differences Between This Proposed AD and the MCAI


The MCAI applies to Model P.68 "Victor," P.68B "Victor," and
P.68R "Victor" airplanes, which are identified on the FAA type
certificate as Model P.68, P.68B, and P.68R airplanes, respectively.
The MCAI requires contacting Vulcanair for approved repair
instructions, while this proposed AD does not.

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
Visual inspection of upper and lower rudder hinges. 2 work-hours x $85 per hour = $170. Not applicable $170 per inspection cycle $2,380 per inspection cycle.
Disassembly for dye inspection of the top rudder hinge (bracket). 7 work-hours x $85 per hour = $595. Not applicable $595 per inspection cycle $8,330 per inspection cycle.
Disassembly for dye inspection for the lower rudder hinge (control tube). 8 work-hours x $85 per hour = $680. Not applicable $680 per inspection cycle $9,520 per inspection cycle.
Dye inspection of upper and lower rudder hinges (post disassembly). 2 work-hours x $85 per hour = $170. Not applicable $170 per inspection cycle $2,380 per rinspection cycle.

The FAA estimates the following costs to do any necessary actions
that would be required based on the results of the proposed inspection.
The FAA has no way of determining the number of airplanes that might
need these actions.

On-Condition Costs

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.
