Federal Register Abstract
We are superseding an existing airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model A119 and AW119 MKII helicopters. The existing AD currently requires inspecting the pilot and copilot engine rotary variable differential transformer (RVDT) control box assemblies to determine if the control gear locking pin is in its proper position. Since we issued that AD, Agusta has developed a terminating action for this inspection. This AD requires the same actions as the existing AD as well as modifying the RVDT control box assemblies. The actions of this AD are intended to prevent failure of an RVDT control box assembly, loss of manual control of the engine throttle, and subsequent loss of control of the helicopter.

Agusta S.p.A. (Agusta) Model A119 and AW119 MKII helicopters. The
existing AD currently requires inspecting the pilot and copilot engine
rotary variable differential transformer (RVDT) control box assemblies
to determine if the control gear locking pin is in its proper position.
Since we issued that AD, Agusta has developed a terminating action for
this inspection. This AD requires the same actions as the existing AD
as well as modifying the RVDT control box assemblies. The actions of
this AD are intended to prevent failure of an RVDT control box
assembly, loss of manual control of the engine throttle, and subsequent
loss of control of the helicopter.
DATES: This AD is effective June 20, 2013.
The Director of the Federal Register approved the incorporation by
reference of a certain document listed in this AD as of June 20, 2013.

SUPPLEMENTARY INFORMATION:
Discussion
On July 3, 2012, at 77 FR 39444, the Federal Register published our
notice of proposed rulemaking (NPRM), which proposed to amend 14 CFR
part 39 to supersede AD 2010-15-51 (75 FR 50863, August 18, 2010). The
NPRM would apply to Agusta model A119 and AW119 MKII helicopters and
proposed to require repetitively inspecting the pilot and co-pilot
control box assemblies for the proper positioning of the locking pins,
and if the locking pin is recessed or extended in excess of 2.0
millimeters from the face of the pin bore, or missing, replacing the
control box assembly. Additionally, the NPRM proposed to require
modifying the pilot and co-pilot control box assemblies to terminate
the repetitive inspection requirements. The proposed requirements were
intended to prevent failure of an RVDT control box assembly, loss of
manual control of the engine throttle, and subsequent loss of control
of the helicopter.
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union, has issued EASA AD
2011-0095-E, dated May 24, 2011, to permanently correct the unsafe
condition addressed in AD 2010-15-51 (75 FR 50863, August 18, 2010) for
the Agusta A119 and AW MKII helicopters. EASA advises that Agusta has
developed a modification to the pilot and co-pilot control box
assemblies that will ``remedy the problem and prevent recurrence.''
This EASA AD requires repetitive inspections of the affected pilot and
co-pilot control box assemblies until a terminating action modification
is made within 8 calendar months of the effective date of the EASA AD.
Comments
We gave the public the opportunity to participate in developing
this AD, but we did not receive any comments on the NPRM (77 FR 39444,
July 3, 2012).
FAA's Determination
These helicopters have been approved by the aviation authority of
Italy and are approved for operation in the United States. Pursuant to
our bilateral agreement with Italy, EASA, its technical representative,
has notified us of the unsafe condition described in the EASA AD. We
are issuing this AD because we evaluated all information provided by
EASA and determined the unsafe condition exists and is likely to exist
or develop on other helicopters of these same type designs and that air
safety and the public interest require adopting the AD requirements as
proposed.
Related Service Information
We reviewed Agusta Alert Bollettino Tecnico (ABT) No. 119-39
Revision A, dated May 23, 2011 (ABT 119-39). The ABT 119-39 describes
procedures for repetitively inspecting the pilot and co-pilot control
box assemblies for correct positioning of the engine RVDT control gear
locking pin and provides instructions on how to modify the pilot and
co-pilot control box assemblies to terminate the repetitive
inspections. EASA classified this ABT as mandatory and issued EAD No.
2011-0095-E, dated May 24, 2011, to ensure the continued airworthiness
of these helicopters.
Costs of Compliance
We estimate that this AD will affect 49 helicopters of U.S.
Registry. We estimate that operators will incur the following costs in
order to comply with this AD. At an average labor rate of $85 per work
hour, inspecting the two RVDT control box assemblies will require about
1.5 hours, for a cost per helicopter of about $128 and a cost to the
U.S. fleet of about $6,272 per inspection cycle. Modification of the
pilot and co-pilot RVDT control box assemblies will require about 8
hours, and required parts will cost about $8, for a total cost per
helicopter of $688 and a cost to the U.S. fleet of $33,712.
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 helicopters 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
[[Page 28729]]
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.
We prepared an economic evaluation of the estimated costs to
comply with this AD and placed it in the AD docket.

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.
