Airworthiness Directives; Airbus Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: 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.

DATES: The FAA must receive comments on this proposed AD by March 28, 
2022.

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.
