Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain Leonardo S.p.a. Model A109E helicopters. This proposed AD was prompted by reports of cracking in the center fuselage frame assembly in the intersection of the lateral pylon and floor spar at station (STA) 1815 on the left- and right-hand sides. This proposed AD would require repetitive inspections of the intersection of the lateral pylon and floor spar at STA 1815 for cracking and, depending on the findings, repair, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.

Background
EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2020-0256, dated November 17, 2020
(EASA AD 2020-0256), to correct an unsafe condition for Leonardo
S.p.A., formerly Finmeccanica S.p.A., AgustaWestland S.p.A., and Agusta
S.p.A., Model A109E helicopters, serial numbers 11001 through 11674
inclusive.
This proposed AD was prompted by reports of cracking in the center
fuselage frame assembly in the intersection of the lateral pylon and
floor spar at STA 1815 on the left- and right-hand sides. The FAA is
proposing this AD to address cracking in the center fuselage frame
assembly in the intersection of the lateral pylon and floor spar at STA
1815 on the left- and right-hand sides, which, if not addressed, could
affect the structural integrity of the helicopter. See EASA AD 2020-
0256 for additional background information.
Related Service Information Under 1 CFR Part 51
EASA AD 2020-0256 requires repetitive inspections of STA 1815 for
cracking, fluorescent liquid penetrant inspections of any cracking to
determine the extent of the cracking, and repair if necessary. For both
the left- and right-hand side repair, the actions include removing
equipment and furnishings to gain access to the work area; testing the
flight control system for correct travel of the flight controls;
performing an operational test of the cockpit and passenger doors
caution system; installing a new forward cap; installing a new angle,
butt strap, and web; installing new cotter pins; and re-installing the
removed equipment and furnishings when the repair is complete.
For the left-hand side repair, the actions also include replacing
the nut plates with new nut plates, and an operational test of the
collective control system and tail rotor control system. For the right-
hand side repair, the actions include an operational test of the cyclic
control system.
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.
FAA's Determination
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 is proposing this AD
after evaluating all known relevant information and determining that
the unsafe condition described previously is likely to exist or develop
on other helicopters of the same type design.
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified
in EASA AD 2020-0256, described previously, as incorporated by
reference, except for any differences identified as exceptions in the
regulatory text of this proposed AD and except as discussed under
``Differences Between this Proposed AD and the MCAI.''
Differences Between This Proposed AD and the MCAI
EASA AD 2020-0256 specifies to accomplish corrective actions if
``any crack is detected in an affected area'' during a required
inspection. Figure 1 of the service information referenced in EASA AD
2020-0256 depicts the affected area, but the FWD bulkhead is mislabeled
as AFT. This proposed AD includes an exception to clarify the correct
location of the FWD bulkhead depicted in Figure 1.
[[Page 47610]]
Explanation of Required Compliance Information
In the FAA's ongoing efforts to improve the efficiency of the AD
process, the FAA developed a process to use some civil aviation
authority (CAA) ADs as the primary source of information for compliance
with requirements for corresponding FAA ADs. The FAA has been
coordinating this process with manufacturers and CAAs. As a result, the
FAA proposes to incorporate EASA AD 2020-0256 by reference in the FAA
final rule. This proposed AD would, therefore, require compliance with
EASA AD 2020-0256 in its entirety through that incorporation, except
for any differences identified as exceptions in the regulatory text of
this proposed AD. Using common terms that are the same as the heading
of a particular section in EASA AD 2020-0256 does not mean that
operators need comply only with that section. For example, where the AD
requirement refers to ``all required actions and compliance times,''
compliance with this AD requirement is not limited to the section
titled ``Required Action(s) and Compliance Time(s)'' in EASA AD 2020-
0256. Service information referenced in EASA AD 2020-0256 for
compliance will be available at <a href="https://www.regulations.gov">https://www.regulations.gov</a> by
searching for and locating Docket No. FAA-2021-0697 after the FAA final
rule is published.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 70 helicopters of U.S. Registry. The FAA estimates the following
costs to comply with this proposed AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Action Labor cost Parts cost Cost per product operators
----------------------------------------------------------------------------------------------------------------
Inspection...................... 6 work-hours x $85 per $0 $510 per inspection $35,700 per
hour = $510 per cycle. inspection cycle.
inspection cycle.
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary repairs
that would be required based on the results of the proposed inspection.
The agency has no way of determining the number of helicopters that
might need these repairs:
On-Condition Costs
----------------------------------------------------------------------------------------------------------------
Action Labor cost Parts cost Cost per product
----------------------------------------------------------------------------------------------------------------
Repair left-hand side................ 120 work-hours x $85 $6,600................. $16,800
per hour = $10,200.
Repair right-hand side............... 120 work-hour x $85 per 5,200.................. 15,400
hour = $10,200.
----------------------------------------------------------------------------------------------------------------
The FAA has included all known costs in its cost estimate.
According to the manufacturer, however, some of the costs of this
proposed AD may be covered under warranty, thereby reducing the cost
impact on affected operators.
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.
