2015-10-07 TURBOMECA S.A.: Amendment 39-18163; Docket No. FAA-2013-1003; Directorate Identifier 2013-NE-33-AD.
(a) EFFECTIVE DATE

    This AD is effective June 12, 2015.

(b) AFFECTED ADS

    This  AD  supersedes  AD 2014-01-01,  Amendment 39-17724  (79 FR 3481,
    January 22, 2014).

(c) APPLICABILITY

    This AD applies to all Turbomeca S.A. Arrius 2F turboshaft engines.

(d) UNSAFE CONDITION

    This AD was prompted by the determination that additional  lubricating
    devices, identifiable by  serial number (S/N),  may have an  incorrect
    bonding of the nozzle on the ejector assembly. We are issuing this  AD
    to prevent failure of the ejector assembly nozzle, which could lead to
    an in-flight shutdown of the engine, damage to the engine, and  damage
    to the helicopter.

(e) COMPLIANCE

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

(1) For engines equipped with a lubricating device having an S/N listed in
    Figure  1  to paragraph  (e)  of this  AD,  within 30  days  after the
    effective date of this AD, inspect the ejector assembly nozzle and the
    tightening  torque.  Use  paragraphs  4.4.2.1  through  4.4.2.3.4.2 of
    Turbomeca Mandatory Service Bulletin (MSB) No. 319 79 4835, Version B,
    dated February 12, 2015, to do the inspection.

(2) For any part that fails the inspection required by paragraph (e)(1) of
    this AD,  before further  flight, remove  and replace  the failed part
    with a part eligible for installation.

Airworthiness Directives; Turbomeca S.A. Turboshaft Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: We are superseding airworthiness directive (AD) 2014-01-01 for
all Turbomeca S.A. Arrius 2F turboshaft engines. AD 2014-01-01 required
a one-time inspection of the ejector assembly nozzle of certain serial
number (S/N) lubricating devices and, if a discrepancy was found,
removal and replacement of the affected ejector assembly nozzle with a
part eligible for installation. This AD requires the same action as AD
2014-01-01 and expands the list of affected S/N lubricating devices.
This AD was prompted by the determination that additional lubricating
devices, identifiable by S/N, may have an incorrect bonding of the
nozzle on the ejector assembly. We are issuing this AD to prevent
failure of the ejector assembly nozzle, which could lead to an in-
flight shutdown (IFSD) of the engine, damage to the engine, and damage
to the helicopter.

DATES: This AD is effective June 12, 2015.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of June 12,

Discussion

On January 2, 2014, we issued AD 2014-01-01, Amendment 39-17724 (79
FR 3481, January 22, 2014), (``AD 2014-01-01''), for all Turbomeca S.A.
Arrius 2F turboshaft engines. AD 2014-01-01 required a one-time
inspection of the ejector assembly nozzle of certain S/N lubricating
devices and, if a discrepancy was found, removal and replacement of the
affected ejector assembly nozzle with a part eligible for installation.
AD 2014-01-01 resulted from an IFSD of an Arriel 1 engine. We issued AD
2014-01-01 to prevent failure of the ejector assembly nozzle, which
could lead to an IFSD of the engine, damage to the engine, and damage
to the helicopter.

Actions Since AD 2014-01-01 Was Issued

Since we issued AD 2014-01-01 it has been determined that
additional lubricating devices, identifiable by S/N, may have the same
unsafe condition, an incorrect bonding of the nozzle on the ejector
assembly. Also since we issued AD 2014-01-01, the European Aviation
Safety Agency (EASA) has issued AD 2015-0057, dated April 1, 2015,
which requires inspection, and replacement as necessary, of the
affected lubricating devices.

Related Service Information Under 1 CFR Part 51

We reviewed Turbomeca S.A. Mandatory Service Bulletin (MSB) No. 319
79 4835, Version B, dated February 12, 2015. The MSB describes
procedures for inspecting the ejector assembly nozzle and, if
necessary, replacing the ejector assembly nozzle. 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 of this AD.

FAA's Determination

We are issuing this AD because we evaluated all the relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other products of the same type design.

AD Requirements

This AD requires a one-time inspection of the ejector assembly
nozzle of certain S/N lubricating devices and, for any ejector assembly
nozzle that fails inspection, removal and replacement with a part
eligible for installation.

FAA's Justification and Determination of the Effective Date

An unsafe condition exists that requires the immediate adoption of
this AD. The FAA has found that the risk to the flying public justifies
waiving notice and comment prior to adoption of this rule because of
the short compliance time requirement. Therefore, we find that notice
and opportunity for prior public comment are impracticable and that
good cause exists for making this amendment effective in less than 30
days.

Costs of Compliance

We estimate that this AD affects 96 engines installed on
helicopters of U.S. registry. We also estimate that it will take about
1 hour per engine to comply with this AD. The average labor rate is $85
per hour. Required parts cost about $563 per engine. Based on these
figures, we estimate the cost of this AD on U.S. operators to be
$62,208.

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.
We are 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) Is not a ``significant rule'' under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation in Alaska to the extent
that it justifies making a regulatory distinction, and
(4) 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.

List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.

Adoption of the Amendment

Accordingly, under the authority delegated to me by the
Administrator, the FAA amends part 39 of the Federal Aviation
Regulations (14 CFR part 39) as follows:

PART 39--AIRWORTHINESS DIRECTIVES

1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

Sec. 39.13 [Amended]

2. The FAA amends Sec. 39.13 by removing airworthiness directive (AD)
2014-01-01, Amendment 39-17724 (79 FR 3481, January 22, 2014), and
adding the following new AD:
