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 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 Gregory Johnson, Aviation Safety
Engineer, FAA, General Aviation & Rotorcraft Section, International
Validation Section, 901 Locust, Room 301, Kansas City, MO 64106-2641.

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 2020-0262, dated November 30, 2020 (referred to after this as
``the MCAI''), to address an unsafe condition on certain serial-
numbered Vulcanair S.p.A. Models P.68R, P.68C, P.68C-TC, P.68
``OBSERVER,'' P.68 ``OBSERVER 2,'' and P.68TC ``OBSERVER'' airplanes.
The MCAI states:

Two occurrences have been reported of finding a damaged
stabilator trim control cable connected to the stabilator trim
actuator assembly, mounted on fuselage frame No.16. The related
technical investigation concluded that the cause of the damage is a
design issue.
This condition, if not detected and corrected, could lead to
failure of an affect [sic] part, preventing trim surface control
(remaining in the last position), possibly resulting in reduced
control of the aeroplane.
To address this potential unsafe condition, and pending a design
improvement, Vulcanair published the [service bulletin] SB, to
provide inspection instructions for detecting damage.
For the reasons described above, this [EASA] AD requires
repetitive inspections of the affected parts, and, depending on
findings, replacement.
This [EASA] AD is considered to be an interim action and further
[EASA] AD action may follow.

You may examine the MCAI in the AD docket at https://www.regulations.gov
by searching for and locating Docket No. FAA-2021-0871.

Related Service Information Under 1 CFR Part 51

The FAA reviewed Vulcanair S.p.A. P.68 Variants Mandatory Service
Bulletin No. 263, dated October 20, 2020. The service information
contains procedures for repetitively inspecting each stabilator trim
control cable part number 5.6067-1, 5.6161-1, 5.6171-1, 5.6231-2, or
5.6231-4 for broken wires and replacing the cable if necessary. 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

This proposed AD would require accomplishing the actions specified
in the service information already described. This proposed AD would
also require reporting inspection results to the manufacturer.

Interim Action

The FAA considers this proposed AD an interim action. The
inspection reports that would be required by this proposed AD will
enable the manufacturer to obtain better insight into the nature,
cause, and extent of the damage, and eventually to develop final action
to address the unsafe condition. Once final action has been identified,
the FAA might consider further rulemaking.

Costs of Compliance

The FAA estimates that this AD, if adopted as proposed, would
affect 127 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 product
Cost on U.S. operators
Inspection 0.50 work-hour x $85 per hour = $42.50 per inspection cycle $0 $42.50 per inspection cycle $5,397.50 per inspection cycle
Report 1 work-hour x $85 per hour = $85 per reporting cycle 0 $85 per inspection cycle $10,795 per inspection cycle

The FAA estimates the following costs to do any replacements 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
this replacement:

On-Condition Costs

Action
Labor cost
Parts cost
Cost per product
Replacement 2 work-hours x $85 per hour = $170
$340
$510

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 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.
