Airworthiness Directives; Airbus Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for all Airbus Helicopters (Airbus) Model AS350B, AS350B1, AS350B2, 
AS350B3, AS350BA, AS350D, AS355E, AS355F, AS355F1, AS355F2, AS355N, 
AS355NP, EC130B4, and EC130T2 helicopters. This proposed AD was 
prompted by a manufacturer assessment that determined additional 
actions are necessary to improve particle detection for main gearboxes 
(MGBs) with certain planet gear bearings installed. This proposed AD 
would require repetitively inspecting the MGB bevel wheel for the 
presence of particles, repetitively inspecting the MGB magnetic plug 
for particles, and prohibit installing an affected MGB unless certain 
requirements are met. These actions are specified in a European Union 
Aviation Safety Agency (EASA) AD, which is proposed for incorporation 
by reference. The FAA is proposing this AD to address the unsafe 
condition on these products.

DATES: The FAA must receive comments on this NPRM by December 20, 2024.

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2023-0044, dated February 28, 2023, 
(EASA AD 2023-0044) to correct an unsafe condition on Airbus Model AS 
350 B, AS 350 D, AS 350 B1, AS 350 B2, AS 350 BA, AS 350 BB, AS 350 B3, 
EC 130 B4, EC 130 T2, AS 355 E, AS 355 F, AS 355 F1, AS 355 F2, AS355 
N, and AS355 NP helicopters. EASA advises that after a fleet design 
review for detection of particles in the MGB, it was determined that 
additional maintenance actions are necessary to improve detection of 
particles in the MGB. The FAA is proposing this AD to detect and 
correct the presence of particles in the MGB, which if not addressed, 
could result in reduced or loss of control of the helicopter.
    You may examine EASA AD 2023-0044 in the AD docket at 
regulations.gov under Docket No. FAA-2024-2419.

Material Incorporated by Reference Under 1 CFR Part 51

    EASA AD 2023-0044 requires repetitive borescope visual inspections 
of the bevel wheel of the affected MGB for particles, collecting and 
analyzing any found particles, and depending on the results, further 
actions, accomplishing corrective action in accordance with the ASB 
defined within, or contacting AH [Airbus Helicopters] for further 
corrective action. EASA AD 2023-0044 also requires accomplishing a 
borescope visual inspection of the bevel wheel of the affected MGB for 
particles following the detection of any particles at the MGB magnetic 
plug during accomplishment of certain maintenance tasks and depending 
on the results, taking corrective action. Lastly, EASA AD 2023-0044 
prohibits installing an affected MGB on any helicopter unless it is a 
serviceable part as defined within and certain requirements are met.
    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.

Other Related Material

    The FAA reviewed Airbus Alert Service Bulletin No. AS350-05.01.04, 
No. AS355-05.00.87, and No. EC130-05A040, each Revision 0, and each 
dated January 25, 2023. This material specifies procedures for 
borescope inspecting the MGB bevel wheel for particles and, depending 
on the results, replacing a damaged epicyclic module or bevel reduction 
module with an airworthy part, and collecting the particles using a 
vacuum pump and analyzing the particles.

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 these same type designs.

Proposed AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified 
in EASA AD 2023-0044, described previously, as incorporated by 
reference, except for any differences identified as exceptions in the

[[Page 87823]]

regulatory text of this proposed AD and except as discussed under 
``Differences Between this Proposed AD and EASA AD 2023-0044.''
    This proposed AD would require certain actions within compliance 
times specified in certain material referenced for compliance in EASA 
AD 2023-0044, particularly for corrective actions for scales, flakes, 
or splinters. Depending on the measurements of the scales, flakes, or 
splinters, corrective actions include close monitoring, metallurgical 
analysis within 50 hours time-in-serivce, or removing each affected 
module and additional actions when certain criteria are exceeded.

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 2023-0044 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
EASA AD 2023-0044 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 2023-0044 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 2023-
0044. Material referenced in EASA AD 2023-0044 for compliance will be 
available at www.regulations.gov by searching for and locating Docket 
No. FAA-2024-2419 after the FAA final rule is published.

Differences Between This Proposed AD and EASA AD 2023-0044

    EASA AD 2023-0044 applies to Model AS350BB helicopters, whereas 
this proposed AD would not because that model is not FAA-type 
certificated.
    Where Note 1 in the material referenced in EASA AD 2023-0044 
specifies the option of 1 mechanical technician and 1 crew member, for 
this proposed AD, the pilot is only permitted to turn the tail rotor 
(b) because the other actions specified in the note must be 
accomplished by persons authorized under 14 CFR 43.3. Therefore, for 
the purposes of this proposed AD, the owner/operator (pilot) may turn 
the tail rotor (b) and must enter compliance with the applicable 
paragraph of this proposed AD in the helicopter maintenance records in 
accordance with 14 CFR 43.9(a) and 91.417(a)(2)(v). The pilot may 
perform this action because it only involves turning the tail rotor 
(b). This action can be performed equally well by a pilot or a 
mechanic. This action is an exception to the FAA's standard maintenance 
regulations.
    This proposed AD would not require complying with paragraph (2) of 
EASA AD 2023-0044. Instead, this proposed AD would require repetitively 
inspecting the MGB magnetic plug for particles and, if there is any 
particle, accomplishing a borescope visual inspection, as specified in 
paragraphs (h)(6)(i) and (ii) of this proposed AD.
    Where the material referenced in EASA AD 2023-0044 specifies 
contacting Airbus Helicopters for a certain action, this proposed AD 
would require accomplishing action in accordance with a method approved 
the FAA, EASA, or Airbus Helicopters' EASA Design Organization 
Approval.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 522 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 proposed AD.
    A repetitive visual borescope inspection of the MGB bevel wheel 
would take 1 work-hour for an estimated cost of $85 per helicopter and 
$44,370 for the U.S. fleet, per inspection cycle.
    If necessary, collecting and performing a metallurgical analysis of 
the detected particles would take 6 work-hours for an estimated cost of 
$510 per helicopter, per analysis.
    Repetitively inspecting the magnetic plugs of the MGB would take 1 
work-hour for an estimated cost of $85 per helicopter and $44,370 for 
the U.S. fleet, per inspection cycle.
    If required, close monitoring would take 2 work-hours for an 
estimated cost of $170 per helicopter, per close monitoring cycle.
    Accomplishing a visual borescope inspection of the MGB bevel wheel 
as a result of an MGB magnetic plug inspection would take 1 work-hour 
for an estimated cost of $85 per helicopter.
    If necessary, replacing an epicyclic module would take 56 work-
hours and parts would cost $50,524 (overhauled) for an estimated cost 
of $55,284 per module.
    If necessary, replacing a bevel reduction module would take 56 
work-hours and parts would cost $18,500 (overhaled) for an estimated 
cost of $23,260 per module.
    Certain corrective action could vary significantly from helicopter 
to helicopter. The FAA has no data to determine the costs to accomplish 
the corrective action.

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.

AD requires using the effective date of this AD.
    (4) Where Note 1 in the material referenced in paragraph (1) of 
EASA AD 2023-0044 specifies the option of 1 mechanical technician 
and 1 crew member, for this AD, the pilot is only permitted to turn 
the tail rotor (b). The owner/operator (pilot) holding at least a 
private pilot certificate may turn the tail rotor (b) and must enter 
compliance with paragraph (g) of this AD in the helicopter 
maintenance records in accordance with 14 CFR 43.9(a) and 
91.417(a)(2)(v). The record must be maintained as required by 14 CFR 
91.417, 121.380, or 135.43. All other actions specified in Note 1 in 
the material referenced in paragraph (1) of EASA AD 2023-0044 must 
be accomplished by persons authorized under 14 CFR 43.3.
    (5) Where Note 2 in the material referenced in paragraph (1) of 
EASA AD 2023-0044 specifies contacting Airbus Helicopters for 
further instructions if the bottom of the radius (a6) of the bevel 
wheel (a3) or head screws (a4) (see Figure 2) are not clearly 
visible, this AD requires, before further flight, accomplishing 
action in accordance with a method approved by the FAA, EASA, or 
Airbus Helicopters' EASA Design Organization Approval (DOA). If 
approved by the DOA, the approval must include the DOA-authorized 
signature.
    (6) Instead of complying with paragraph (2) of EASA AD 2023-
0044, comply with the actions required by paragraphs (h)(6)(i) and 
(ii) of this AD.
    (i) After the effective date of this AD, and within the
