    Within 90 hours time-in-service after the effective date of this AD or
    before the next autorotation training flight, whichever occurs first:

(1) For each collective,  remove the protective boot  along the collective
    and measure the clearance  between the edge of the collective tab hook
    (a) and the edge of the low pitch locking pin (b) as shown in Figure 1
    of  Airbus Helicopters  Alert Service Bulletin  ASB  No. EC130-67A019,
    Revision 0, dated February 23, 2016 (ASB EC130-67A019).  If the clear-
    ance is less than 5 mm (0.196 in), before further flight:

(i) Adjust  the  clearance  by  following the Accomplishment Instructions,
    paragraph 3.B.3., of ASB EC130-67A019.

(ii) Test the collective for proper engagement  of  the  low pitch locking
     pin by following  the Accomplishment Instructions,  paragraph 3.B.4.,
     of ASB EC130-67A019.

(2) Re-install the protective boot  on the collective,  ensuring  that  no
    boot folds have entered the space between  the collective tab hook and
    the low pitch locking pin,  by  following  the Accomplishment Instruc-
    tions, paragraph 3.B.5., of ASB EC130-67A019.

(h) SPECIAL FLIGHT PERMITS

    Special flight permits are prohibited.

(i) ALTERNATIVE METHODS OF COMPLIANCE (AMOCS)

(1) The Manager, International Validation Branch,  FAA,  has the authority
    to approve AMOCs for this AD, if requested using the procedures  found
    in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to
    your principal inspector or local Flight Standards District Office, as
    appropriate. If  sending information  directly to  the manager  of the
    International  Validation  Branch, send  it  to the  attention  of the
    person identified in paragraph (j)(1)  of this AD. Information may  be
    emailed to: 9-AVS-AIR730-AMOC@faa.gov.

(2) Before using any approved AMOC,  notify your appropriate principal in-
    spector, or lacking  a principal inspector,  the manager of  the local
    flight standards district office/certificate holding district office.

SUPPLEMENTARY INFORMATION:

Background

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to Airbus Helicopters
Model EC130B4 and Model EC130T2 helicopters. The NPRM published in the
Federal Register on July 7, 2021 (86 FR 35695). In the NPRM, the FAA
proposed to require, within 90 hours time-in-service (TIS) after the
effective date of the AD, or before the next autorotation training
flight, whichever occurs first, removing the protective boot along the
collective and measuring the clearance between the collective tab hook
(hook) and low pitch locking pin (pin). If the clearance is less than 5
mm (0.196 in), adjusting the clearance between the hook and the pin to
prevent interference was proposed. The NPRM then proposed to require
re-installing the protective boot in accordance with the manufacturer's
service information. The NPRM was prompted by EASA AD 2017-0062, dated
April 11, 2017 (EASA AD 2017-0062), issued by EASA, which is the
Technical Agent for the Member States of the European Union, to correct
an unsafe condition for Airbus Helicopters Model EC130B4 and EC130T2
helicopters. EASA states that during an autorotation test conducted
during an acceptance flight, the pilot felt a jamming sensation when
pushing the collective to the low pitch position, and he subsequently
was able to free the collective by pulling on it. According to EASA, an
analysis determined that the hook and the pin were extremely close, and
that a fold in the control lever boot may have become caught between
the two components. EASA states that this condition, if not detected
and corrected, could result in an untimely locking of the collective
and subsequent reduced control of the helicopter.
Accordingly, EASA AD 2017-0062 requires inspecting and adjusting,
if necessary, the clearance between the hook and the pin while in the
low pitch position.

Discussion of Final Airworthiness Directive

Comments

The FAA received no comments on the NPRM or on the determination of
the costs.

Conclusion

These helicopters have been approved by EASA and are approved for
operation in the United States. Pursuant to the FAA's bilateral
agreement with the European Union, EASA has notified the FAA about the
unsafe condition described in its AD. The FAA reviewed the relevant
data and determined that air safety requires adopting this AD as
proposed. Accordingly, the FAA is issuing this AD to address the unsafe
condition on these helicopters.

Related Service Information Under 1 CFR Part 51

The FAA reviewed Airbus Helicopters Alert Service Bulletin ASB No.
EC130-67A019, Revision 0, dated February 23, 2016, which specifies
inspecting and adjusting the clearance between the hook and pin.
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.

Differences Between This AD and the EASA AD

The EASA AD requires compliance within 165 hours TIS or 3 months,
whichever occurs first. Since the unsafe condition occurred at a
collective position commanded during an autorotation, this AD requires
compliance within 90 hours TIS after
the effective date of this AD or before the next autorotation training
flight, whichever occurs first. Based on the average fleet usage, 90
hours TIS corresponds with the 3-month compliance requirement of the
EASA AD.

Costs of Compliance

The FAA estimates that this AD affects 214 helicopters of U.S.
Registry. At an average labor rate of $85 per work-hour, the FAA
estimates that operators may incur the following costs in order to
comply with this AD. Removing the protective boot will require about 2
work-hours for a cost of $170 per helicopter and a cost of $36,380 for
the U.S. fleet. Determining the clearance between the hook and pin will
require about 0.5 work-hour, for a cost of $43 per helicopter and a
cost of $9,202 for the U.S. fleet. If required, adjusting the clearance
will take about 2 work-hours for a cost of $170 per helicopter. Re-
installing the protective boot will require about 2 work-hours, for a
cost of $170 per helicopter and a cost of $36,380 for the U.S. fleet.

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 helicopters identified in this rulemaking action.

Regulatory Findings

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 this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(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.
