[Docket No. FAA-2021-0871; Project Identifier MCAI-2020-01581-A;
Amendment 39-21874; AD 2021-26-15]
Airworthiness Directives; Vulcanair S.p.A. Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
SUMMARY: The FAA is adopting a new airworthiness directive (AD)
certain km, Vulcanair S.p.A. Model P.68C, P.68C-TC, P.68 ``OBSERVER,''
P.68 OBSERVER 2, P.68R, and P.68TC OBSERVER airplanes. This AD was
prompted by 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 a damaged stabilator trim control cable. This
AD requires inspecting the stabilator trim control cables and replacing
if necessary. This AD also requires reporting the results of each
inspection to Vulcanair S.p.A. The FAA is issuing this AD to address
the unsafe condition on these products.
DATES: This AD is effective February 15, 2022.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of February 15,

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to certain serial-numbered
Vulcanair S.p.A. Model P.68C, P.68C-TC, P.68 ``OBSERVER,'' P.68
OBSERVER 2, P.68R, and P.68TC OBSERVER airplanes. The NPRM published in
the Federal Register on October 8, 2021 (86 FR 56229). The NPRM was
prompted by MCAI originated by the European Union Aviation Safety
Agency (EASA), which is the Technical Agent for the Member States of
the European Union. EASA issued EASA AD 2020-0262, dated November 30,
2020 (referred to after this as ``the MCAI''), to correct an unsafe
condition on certain serial-numbered Vulcanair S.p.A. Model 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
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
This [EASA] AD is considered to be an interim action and further
[EASA] AD action may follow.

Discussion of Final Airworthiness Directive
The FAA received no comments on the NPRM or on the determination of
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
referenced above. The FAA 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. P.68 Variants 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.
The FAA considers this AD an interim action. The inspection reports
required by this 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
Costs of Compliance
The FAA estimates that this AD affects 127 airplanes of U.S.
The FAA estimates the following costs to comply with this AD:
||Cost per airplane
||Cost on U.S. operators
||0.50 work-hour x $85 per hour
= $42.50 per inspection cycle
||$42.50 per inspection cycle
||1 work-hour x $85 per hour =
$85 per reporting cycle
||$85 per inspection cycle
||$10,795 per inspection
The FAA estimates the following costs
to do any replacements that
would be required based on the results of the inspection. The FAA has
no way of determining the number of airplanes that might need this
||2 work-hours x $85 per hour =
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,

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.
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
(1) Is not a ``significant regulatory action'' under Executive
(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.
