Abstract
The FAA proposes to supersede Airworthiness Directive (AD) 2020-22-01 which applies to all Airbus Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 helicopters. AD 2020-22-01 requires inspecting the affected parts and associated frame bores for discrepancies, applicable corrective actions, and reporting certain information if necessary. Since the FAA issued AD 2020-22-01, a significant number of reports were received of finding corrosion on the affected parts. This proposed AD would retain the requirements of AD 2020-22-01, add recurring inspections, and update the applicable service information. The FAA is proposing this AD to address the unsafe condition on these products.

Background
The FAA issued AD 2020-22-01, Amendment 39-21297 (85 FR 69126,
November 2, 2020), (AD 2020-22-01), for all Airbus Helicopters Model
AS332C, AS332C1, AS332L, and AS332L1 helicopters. AD 2020-22-01
requires, within certain compliance times specified in the
manufacturers service information, inspecting the attachment fittings
and attachment screws of the main gearbox (MGB) suspension bars and
their frame bores for discrepancies and corrective actions in
accordance with the actions specified in the service information. AD
2020-22-01 also requires sending certain information to the
manufacturer. AD 2020-22-01 resulted from reports of corrosion on
attachment screws and fittings fastening the MGB suspension bars to the
fuselage. The FAA issued AD 2020-22-01 to address corrosion on
attachment fittings and attachment screws for the MGB suspension bars.
AD 2020-22-01 was prompted by EASA AD 2019-0295, dated December 5,
2019 (EASA AD 2019-0295), issued by EASA, which is the Technical Agent
for the Member States of the European Union, to correct an unsafe
condition for all Airbus Helicopters Model AS 332 C, AS 332 C1, AS 332
L, and AS 332 L1 helicopters, all manufacturer serial numbers. EASA
advised that there were reports of corrosion on attachment screws and
fittings fastening the rear MGB suspension bars, right and left hand
sides, to the fuselage, and the attachment screws and fitting fastening
the front MGB suspension bar to the fuselage. EASA advised that
subsequent investigation determined that during maintenance visits of
an identified batch of helicopters between September 2012 and April
2019, application of compound sealant on MGB suspension bar attachment
screws may not have been accomplished using the approved maintenance
data. This condition, if not addressed, could lead to structural
failure of the MGB attachment screws, resulting in detachment of MGB
suspension bars from the fuselage and subsequent loss of control of the
helicopter.
Accordingly, EASA AD 2019-0295 required a one-time inspection of
the affected parts, and depending on findings, accomplishment of
applicable corrective actions. The compliance times varied depending on
helicopter configuration.
Actions Since AD 2020-22-01 Was Issued
Since the FAA issued AD 2020-22-01, EASA issued EASA AD 2021-0222,
dated October 6, 2021 (EASA AD 2021-0222), which supersedes EASA AD
2019-0295. EASA advises a significant number of reports were received
about corrosion being detected on the affected parts. EASA also advises
Airbus Helicopters issued updated service information, which includes
instructions for repetitive inspections. Accordingly, EASA AD 2021-0222
retains the requirements of EASA AD 2019-0295 and adds repetitive
inspections and updated service information. Additionally, Airbus
Helicopters advised of a typo in the applicable service information in
the reference to G.2 of one of the work cards. Accordingly, the FAA has
identified this typo in the exceptions in the regulatory text of this
proposed AD.
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 products of the same type design.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Airbus Helicopters Alert Service Bulletin (ASB)
No. AS332-53.02.05, Revision 2, and ASB No. AS332-53.02.07, Revision 1,
both dated August 19, 2021, which specify procedures for inspecting the
attachment fittings and attachment screws of the MGB suspension bars
and their frame bores for discrepancies and corrective actions. This
inspection includes inspecting the attachment fittings for corrosion
and inspecting the attachment screws for corrosion and evidence of
sealing compound. The corrective actions include replacing or
[[Page 7772]]
repairing corroded parts and replacing screws that have sealing
compound on them. These documents are distinct since they apply to
different helicopter models in different configurations.
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.
Other Related Service Information
The FAA also reviewed Airbus Helicopters ASB No. AS332-53.02.05,
Revision 0, dated April 18, 2019; Airbus Helicopters ASB No. AS332-
53.02.05, Revision 1, dated March 2, 2020; and Airbus Helicopters ASB
No. AS332-53.02.07, Revision 0, dated October 21, 2019, which also
specify procedures for inspecting the attachment fittings and
attachment screws of the MGB suspension bars and their frame bores for
discrepancies and corrective actions.
Proposed AD Requirements
This proposed AD would retain all requirements of AD 2020-22-01.
This proposed AD would add repetitive inspections and update the
applicable service information. This proposed AD would require
accomplishing the actions specified in the service information
described previously.
Costs of Compliance
The FAA estimates that this AD would affect 10 helicopters of U.S.
Registry. Labor rates are estimated at $85 per work-hour. Based on
these numbers, the FAA estimates that operators may incur the following
costs in order to comply with this proposed AD.
Inspecting each attachment screw and fitting of the rear MGB
suspension bars; each attachment screw and fitting of the front MGB
suspension bar; and the frame bores would take about 16 work-hours, for
an estimated cost of $1,360 per helicopter and $13,600 for the U.S.
fleet per inspection cycle.
The FAA estimates the following costs to do any necessary on-
condition corrective actions that would be required based on the
results of the inspection. The agency has no way of determining the
number of helicopters that might need these on-condition replacements:
If required, replacing an affected screw, nut, split pin, concave
washer, convex washer, or peel shim would take a minimal amount of time
with a minimal cost.
If required, replacing an affected MGB attachment fitting would
take about 8 work-hours and parts would cost about $7,000 for an
estimated cost of $7,680 per replacement.
If required, reporting any discrepancies to Airbus Helicopters
would take about 1 work-hour for an estimated cost of $85 per
helicopter.
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, 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
The FAA has 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 that the 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.
