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. Models P.68C, P.68C-TC, P.68 ``OBSERVER,'' 
P.68 OBSERVER 2, P.68R, and P.68TC OBSERVER airplanes. This proposed 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 describes 
the unsafe condition as a damaged stabilator trim control cable. This 
proposed AD would require inspecting the stabilator trim control cables 
and replacing if necessary. This proposed AD would also require 
reporting the results of each inspection to Vulcanair S.p.A. The FAA is 
proposing this AD to address the unsafe condition on these products.

DATES: The FAA must receive comments on this proposed AD by November 
22, 2021.

closing date and may amend the 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 
https://www.regulations.gov, including any personal information you 
provide. The agency will also post a report summarizing each 
substantive verbal contact received about this proposed AD.

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 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

[[Page 56230]]

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. 
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 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:

    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:

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.
