Download as PDF Federal Register / Vol. 81, No. 211 / Tuesday, November 1, 2016 / Rules and Regulations 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 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

This condition, if not corrected, could lead to crack initiation and propagation in the centrifugal impeller bore area, possibly resulting in centrifugal impeller failure, with consequent damage to, and reduced control of, the helicopter. To address this potential unsafe condition, the life of the affected centrifugal impellers was reduced and Turbomeca published Mandatory Service Bulletin (MSB) 292 72 0848 to inform operators about the life reduction and to provide instructions for the replacement of the affected centrifugal impellers.

the grinding operation required by modification TU376, which increases
the clearance between the rear curvic coupling of the centrifugal
impeller and the fuel injection manifold. We are issuing this AD to
prevent failure of the centrifugal impeller, uncontained centrifugal

SUPPLEMENTARY INFORMATION:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would apply to the specified products. The
NPRM was published in the Federal Register on July 28, 2016 (81 FR
49575). The NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:

Turbomeca reported an anomaly that was generated during the
grinding operation associated to the application of modification
TU376, which increases the clearance between the rear curvic
coupling of the centrifugal impeller and the fuel injection
manifold.
This condition, if not corrected, could lead to crack initiation
and propagation in the centrifugal impeller bore area, possibly
resulting in centrifugal impeller failure, with consequent damage
to, and reduced control of, the helicopter. To address this
potential unsafe condition, the life of the affected centrifugal
impellers was reduced and Turbomeca published Mandatory Service
Bulletin (MSB) 292 72 0848 to inform operators about the life
reduction and to provide instructions for the replacement of the
affected centrifugal impellers.
For the reasons described above, this AD requires replacement of
each affected centrifugal impeller before it exceeds the applicable
reduced life limit.

You may obtain further information by examining the MCAI in the AD
docket on the Internet at https://www.regulations.gov by searching for
and locating Docket No. FAA-2016-6990.

Comments

We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (81 FR 49575, July 28,
2016) or on the determination of the cost to the public.

Conclusion

We reviewed the available data and determined that air safety and
the public interest require adopting this AD as proposed.

Related Service Information

Turbomeca S.A. has issued Mandatory Service Bulletin (MSB) 292 72
0848, Version B, dated April 13, 2016. The MSB describes procedures for
reducing the life limit of the centrifugal impellers affected by an
anomaly that occurred during the grinding operation required by
modification TU376. 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.

Costs of Compliance

We estimate that this AD affects 3 engines installed on helicopters
of U.S. registry. We also estimate that it would take about 22 hours
per engine to comply with this AD. The average labor rate is $85 per
hour. Required parts cost about $96,518 per engine. Based on these
figures, we estimate the cost of this AD on U.S. operators to be
$295,164.

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

We determined that 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 this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Is not a ``significant rule'' under the 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.

Adoption of the Amendment

Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

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

[[Page 75689]]

Sec. 39.13 [Amended]

0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive (AD):

2016-22-10 Turbomeca S.A.: Amendment 39-186990; Docket No. FAA-2016-
6990; Directorate Identifier 2016-NE-14-AD.

(a) Effective Date

This AD becomes effective December 6, 2016.

(b) Affected ADs

None.

This AD applies to certain Arriel 1, 1A, 1A1, 1A2, 1B, 1B2, 1C,
1C1, 1C2, 1D, 1D1, 1E, 1E2, 1K1, 1S, and 1S1 turboshaft engines,
with modification TU376 installed.

(d) Reason

This AD was prompted by an anomaly that occurred during the
grinding operation required by modification TU376, which increases
the clearance between the rear curvic coupling of the centrifugal
impeller and the fuel injection manifold. We are issuing this AD to
prevent failure of the centrifugal impeller, uncontained centrifugal
impeller release, damage to the engine, and damage to the
helicopter.

(e) Actions and Compliance

Comply with this AD within the compliance times specified,
unless already done.
(1) Remove from service, any centrifugal impeller listed in
Table 1 to paragraph (e) of this AD, before exceeding the applicable
cycles since new (CSN) and replace with a centrifugal impeller not
listed in Table 1 to paragraph (e) of this AD.
