Airworthiness Directives; Leonardo S.p.a. (Type Certificate 
Previously Held by Agusta S.p.A.) Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Leonardo S.p.a. (type certificate previously held by Agusta 
S.p.A.) Model A109A and A109A II helicopters. This AD was prompted by a 
report of internal corrosion on a main rotor (M/R) blade. This AD 
requires repetitively inspecting affected M/R blades and accomplishing 
film analysis and repair in accordance with certain approved methods. 
The FAA is issuing this AD to address the unsafe condition on these 
products.

DATES: This AD is effective February 22, 2022.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of February 22, 
2022.

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 Leonardo S.p.a. (type 
certificate previously held by Agusta S.p.A.) Model A109A and A109A II 
helicopters with an M/R blade part number (P/N) 109-0103-01-115 
installed. The NPRM published in the Federal Register on October 29, 
2021 (86 FR 59890). In the NPRM, the FAA proposed to require 
repetitively radiographic inspecting each affected M/R blade and 
accomplishing film analysis and repair in accordance with certain 
approved methods. The NPRM was prompted by EASA AD 2020-0065, dated 
March 20, 2020 (EASA AD 2020-0065), issued by EASA, which is the 
Technical Agent for the Member States of the European Union, to correct 
an unsafe condition for all Leonardo S.p.A., Agusta S.p.A., Costruzioni 
Aeronautiche Giovanni Agusta Model A109A and A109AII helicopters. EASA 
advises of a report of internal corrosion on an M/R blade. Leonardo 
Helicopters advises that the corrosion was on the spar near the inertia 
weights between STA1250 and STA1630. Leonardo Helicopters further 
advises that the issue is related to design and production processes of 
the M/R blades. This condition, if not addressed, could result in 
failure of an M/R blade and subsequent loss of control of the 
helicopter.
    Accordingly, EASA AD 2020-0065 requires inspecting M/R blades P/N 
109-0103-01-115 and depending on the results, corrective action. EASA 
AD 2020-0065 also prohibits installation of an affected M/R blade 
unless it passed the required inspection within 24 months prior to 
installation on a helicopter.

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. Except for minor editorial changes, 
this AD is adopted as proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Leonardo Helicopters Alert Service Bulletin No. 
109-155, dated March 13, 2020 (ASB 109-155), for Leonardo S.p.a. Model 
A109A and A109AII helicopters. This service information specifies 
procedures for X-ray inspecting M/R blades P/N 109-0103-01-115 and 
sending the films to Leonardo Helicopters S.p.a. for analysis. 
Depending on the outcome, ASB 109-155 specifies procedures for re-
identifying the M/R blades.
    This material 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.

Interim Action

    The FAA considers this AD an interim action. The design approval 
holder is currently developing a modification that will address the 
unsafe condition identified in this AD. Once this modification is 
developed, approved, and available, the FAA might consider additional 
rulemaking.

Differences Between This AD and the EASA AD

    The compliance time in EASA AD 2020-0065 is time-in-service of the 
airframe, whereas the compliance time in this AD is time-in-service of 
the affected M/R blade as installed on the airframe. EASA AD 2020-0065 
requires sending developed films to Leonardo Helicopters S.p.a. for 
analysis and contacting Leonardo for approved corrective action(s) 
instructions, whereas this AD requires film analysis and repair of an 
affected blade in accordance with a method approved by

[[Page 2529]]

the Manager, General Aviation & Rotorcraft Section, International 
Validation Branch, FAA; or EASA; or Leonardo S.p.a Helicopters' EASA 
Design Organization Approval (DOA). If approved by the DOA, the 
approval must include the DOA-authorized signature.

Costs of Compliance

    The FAA estimates that this AD affects 28 helicopters of U.S. 
registry. Labor rates are estimated at $85 per work-hour. Based on 
these numbers, the FAA estimates the following costs to comply with 
this AD.
    Inspecting the M/R blades takes about 10 work-hours for an 
estimated cost of $850 per helicopter and $23,800 for the U.S. fleet, 
per inspection cycle. Sending the film for analysis, which is 
considered a reporting requirement in this AD, takes about 1 work-hour 
for an estimated cost of $85 per helicopter and $2,380 for the U.S. 
fleet, per inspection cycle.
    The FAA has no way of determining the costs pertaining to the film 
analysis or any necessary repairs.

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 take 
approximately 1 hour per response, including the time for reviewing 
instructions, searching existing data sources, gathering and 
maintaining the data needed, and 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

    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.
