The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Airbus Helicopters Model SA330J helicopters. The NPRM published in the Federal Register on December 4, 2020 (85 FR 78277). The NPRM was prompted by a report of failure of a second stage planet gear of the MGB on a Model EC225 helicopter. Following a review of design similarities, it was determined that such an event might also occur on Model SA330J helicopters. The NPRM proposed to require replacement of the MGB particle detector assembly with an improved, elongated MGB particle detector assembly, as specified in an EASA AD. The FAA is issuing this AD to address failure of a second stage planet gear of the MGB, which could lead to loss of control of the helicopter. See the MCAI for additional background information.

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.

SUPPLEMENTARY INFORMATION: Discussion The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to Leonardo Model A109S helicopters, serial number (S/N) 22702, 22703, 22705, and 22706 and AW109SP helicopters with S/N up to 22386 inclusive, except S/N 22375 and S/N 22376. The NPRM published in the Federal Register on December 21, 2020 (85 FR 82972). The NPRM proposed to require, before further flight, for certain serial-numbered helicopters, installing a placard and revising the existing RFM for your helicopter. The NPRM also proposed to require within 5 hours time-in-service (TIS), for certain model helicopters, inspecting the installation of the terminal lugs, shimming the installation of the baggage fairing assembly (fwd up), and installing a silicon rubber protection over the blind rivets of the hinge in accordance with certain applicable service information. The NPRM also proposed to require within 10 hours TIS and thereafter at PO 00000 Frm 00017 Fmt 4700 Sfmt 4700 13987 intervals not to exceed 25 hours TIS until protective coverings are installed, removing the baggage fairing assembly (fwd up), removing the rubber protections, and inspecting the cable assembly routing of both circuit breaker panels for damage. Depending on the outcome of these inspections, the NPRM proposed to require repairing or replacing certain parts. The NPRM also proposed to require, within 200 hours TIS, modifying the helicopter to incorporate a certain protective coverings, which would provide a terminating action for the repetitive inspections. The proposed requirements were intended to prevent fire in the baggage department. The NPRM was prompted by EASA Emergency AD No. 2018–0120–E, dated May 29, 2018 (EASA AD 2018–0120–E), issued by EASA, which is the Technical Agent for the Member States of the European Union, to correct an unsafe condition for Leonardo S.p.a. (formerly Finmeccanica S.p.A., AgustaWestland S.p.A., Agusta S.p.A.) Model A109S and AW109SP helicopters. EASA advises that an occurrence was reported on an AW109SP helicopter experiencing fire ignition and smoke in the baggage compartment. The investigation determined the event was due to chafing of electrical wiring and further analysis indicated that due to similarity of design, this event could also occur on A109S helicopters. Accordingly, the EASA AD requires modification of the affected baggage fairing assembly (fwd up) part number (P/N) 109–0344–31– 101 and temporarily amending the existing RFM and installing a placard prohibiting carrying any loads in the baggage compartment. After EASA AD 2018–0120–E was issued, a second occurrence was reported of fire ignition and smoke in the baggage compartment, and as a precautionary measure, Leonardo Helicopters issued a series of emergency alert service bulletins providing instructions to prevent damage of electrical assemblies in the baggage compartment. Accordingly, EASA issued EASA Emergency No. 2018– 0149–E, dated July 13, 2018 (EASA AD 2018–0149–E), which retains the requirements of EASA AD 2018–0120– E, and also requires repetitive inspections of the baggage compartment electrical assemblies and depending on the inspection outcomes, repairing or replacing certain parts. Also, EASA AD 2018–0149–E expands the applicability to include three additional serialnumbered helicopters, and requires a modification, which acts as a terminating action for the repetitive inspections.

(MGB). This AD requires replacement of the MGB particle detector 
assembly with an improved, elongated MGB particle detector assembly, as

SUPPLEMENTARY INFORMATION: 

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2019-0108, dated May 17, 2019 (EASA 
AD 2019-0108) (also referred to as the Mandatory Continuing 
Airworthiness Information, or the MCAI), to correct an unsafe condition 
for all Airbus Helicopters Model SA330J helicopters.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to all Airbus Helicopters 
Model SA330J helicopters. The NPRM published in the Federal Register on 
December 4, 2020 (85 FR 78277). The NPRM was prompted by a report of 
failure of a second stage planet gear of the MGB on a Model EC225 
helicopter. Following a review of design similarities, it was 
determined that such an event might also occur on Model SA330J 
helicopters. The NPRM proposed to require replacement of the MGB 
particle detector assembly with an improved, elongated MGB particle 
detector assembly, as specified in an EASA AD.
    The FAA is issuing this AD to address failure of a second stage 
planet gear of the MGB, which could lead to loss of control of the 
helicopter. See the MCAI for additional background information.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The FAA received no comments on the NPRM or 
on the determination of the cost to the public.

Conclusion

    The FAA reviewed the relevant data and determined that air safety 
and the public interest require adopting this final rule as proposed, 
except for minor editorial changes. The FAA has determined that these 
minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

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.
