2021-20-12 LEONARDO S.P.A: Amendment 39-21750; Docket No. FAA-2021-0608; Project Identifier 2019-SW-119-AD.
(a) EFFECTIVE DATE

    This airworthiness directive (AD) is effective November 22, 2021.

(b) AFFECTED ADS

    None.

(c) APPLICABILITY

    This AD  applies to  Leonardo S.p.a.  Model AB139,  AW139, AB412,  and
    AB412 EP helicopters, certificated  in any category, with  an affected
    part as identified in European Union Aviation Safety Agency (EASA)  AD
    2019-0311, dated December 19, 2019 (EASA AD 2019-0311), installed.

(d) SUBJECT

    Joint Aircraft System Component (JASC) Code: 3212, Emergency Flotation
    Section.

(e) UNSAFE CONDITION

    This AD was prompted by failure of an Emergency Flotation System (EFS)
    float compartment to inflate during maintenance of the EFS. The FAA is
    issuing this  AD to  address a  blocked float  supply hose. The unsafe
    condition, if not addressed, could  result in partial inflation of  an
    EFS  float  during  an emergency  landing  on  water and  subsequently
    preventing a timely egress from the helicopter, which could result  in
    injury to helicopter occupants.

(f) COMPLIANCE

    Comply with this AD within the compliance times specified,  unless al-
    ready done.

(g) REQUIREMENTS

    Except as specified in paragraph (h)  of this AD:  Comply with all re-
    quired actions and compliance times specified in,  and  in  accordance
    with, EASA AD 2019-0311.

(h) EXCEPTIONS TO EASA AD 2019-0311

(1) Where EASA AD 2019-0311 refers to its effective date, this AD requires
    using the effective date of this AD.

(2) Where EASA AD 2019-0311  requires compliance in terms of flight hours,
    this AD requires using hours time-in-service (TIS).

(3) Where paragraph (1)  of  EASA AD 2019-0311  requires  inspecting  each
    affected part  within the compliance time  specified in Table 2 of its

    accordance with Aircraft Maintenance Manual (AMM)  or Aircraft Mainte-
    nance Publication (AMP)  can  perform  the  procedure  defined in this
    Service Bulletin," this AD requires that the work be accomplished by a
    mechanic that meets the requirements of 14 CFR part 65 subpart D.

(5) Where paragraph (2) of EASA AD 2019-0311  specifies  replacing  an EFS
    supply hose that fails the inspection,  this AD requires  removing the
    hose from service.

(6) This AD does not require the "Remarks" section of EASA AD 2019-0311.

SUPPLEMENTARY INFORMATION:

Background

The EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2019-0311, dated December 19, 2019
(EASA AD 2019-0311), to correct an unsafe condition for Leonardo
S.p.A., formerly Finmeccanica Helicopter Division, AgustaWestland,
Agusta S.p.A., Model AB139, AW139, AB412, and AB412EP helicopters.
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to certain Leonardo S.p.a.
Model AB139, AW139, AB412, and AB412EP helicopters. The NPRM published
in the Federal Register on July 30, 2021 (86 FR 40962). The NPRM was
prompted by failure of an EFS float compartment to inflate during
maintenance of the EFS. The NPRM proposed to require inspecting each
EFS supply hose and depending on the results, re-identifying or
removing the EFS supply hose from service, as specified in an EASA AD.
The FAA is issuing this AD to address a blocked float supply hose.
See EASA AD 2019-0311 for additional background information.

Discussion of Final Airworthiness Directive

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.

Related Service Information Under 1 CFR Part 51

EASA AD 2019-0311 specifies inspecting certain EFSs and depending
on the results, re-identifying the float supply hose with a green heat
shrinkable sleeve if the float supply hose passes an inspection, or
replacing the float supply hose with a serviceable float supply hose.
EASA AD 2019-0311 also prohibits installing a float supply hose unless
it passes the inspection and is re-identified.
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 Service Information

The FAA reviewed Safran Service Bulletin 025-69-19, Revision 00,
dated November 22, 2019 (SB 025-69-19), which is attached as Annex A to
Leonardo Helicopters Alert Service Bulletin (ASB) No. 139-610 and
Emergency ASB No. 412-157, each dated December 17, 2019. SB 025-69-19
specifies procedures for inspecting for blockage through the float
supply hoses of the EFS inflation system.

Differences Between This AD and the EASA AD

EASA AD 2019-0311 requires inspecting each affected part in Group A
within 400 flight hours (FH) or 12 months, whichever occurs first,
whereas this AD requires inspecting each affected part in that group
within 100 hours time-in-service instead. EASA AD 2019-0311 requires
inspecting each affected part in Group C within 300 FH or during the
next scheduled ``18 months'' inspection, whichever occurs first,
whereas this AD requires inspecting each affected part in that group
within 15 hours time-in-service instead to address the unsafe condition
as soon as practical as there are no Group C aircraft registered in the
U.S.; the proposed compliance time matches those same model aircraft
found in Group D. Where the service information referenced in EASA AD
2019-0311 specifies ``operator able to perform the EFS maintenance in
accordance with Aircraft Maintenance Manual (AMM) or Aircraft
Maintenance Publication (AMP) can perform the procedure defined in this
Service Bulletin,'' this AD requires that the work be accomplished by a
mechanic that meets the requirements of 14 CFR part 65 subpart D. Where
EASA AD 2019-0311 specifies replacing an affected float supply hose
that fails the inspection, this AD requires removing the float supply
hose from service instead.

Costs of Compliance

The FAA estimates that this AD affects 129 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 AD.
Inspecting each EFS supply hose takes about 0.25 work-hour for an
estimated cost of $21 per hose. Re-identifying each EFS supply hose
would take a minimal amount of time at a nominal cost.
Replacing an EFS supply hose takes up to 8 work-hours and parts
cost between $2,500 and $9,500 for a set of float supply hoses, for an
estimated cost of up to $10,180 per helicopter.
According to Safran's service information, some of the costs of
this AD may be covered under warranty, thereby reducing the cost impact
on affected individuals. The FAA does not control warranty coverage by
Safran; accordingly, all costs are included in this cost estimate.

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.
