14 CFR Part 39

Amendment 39-17836; AD 2014-09-01]

Airworthiness Directives; AgustaWestland S.p.A. (Type Certificate 
Previously Held by Agusta S.p.A.) (Agusta) Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for Agusta 
Model A109C, A109E, A109K2, and A119 helicopters. This AD requires a 
recurring visual inspection of the tail rotor (T/R) blade retaining 
bolts (bolts) for a crack, corrosion, damage, or missing cadmium 
plating in the central part of the bolt and, depending on findings, a 
liquid penetrant inspection. This AD also requires replacing a cracked 
or damaged bolt. This AD was prompted by two reported incidents of 
cracked bolts. The actions of this AD are intended to detect an 
unairworthy bolt and prevent failure of a bolt, release of a T/R blade, 
and subsequent loss of control of the helicopter.

DATES: This AD is effective June 5, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of certain documents listed in this AD as of June 5, 2014.

SUPPLEMENTARY INFORMATION:

Discussion

    On November 20, 2013, at 78 FR 69595, the Federal Register 
published our notice of proposed rulemaking (NPRM), which proposed to 
amend 14 CFR part 39 by adding an AD that would apply to certain Agusta 
Model A109C, A109E, A109K2, and A119 helicopters. The NPRM proposed to 
require a recurring visual inspection of each bolt, part number (P/N) 
109-8131-09-1, for a crack, corrosion, a nick, other damage, or missing 
cadmium plating in the central part of the bolt. If a crack is not 
detected by the visual inspection, the NPRM proposed to require a 
liquid penetrant inspection. If there is a crack, corrosion, damage, or 
missing cadmium plating in the central part of the bolt, the NPRM 
proposed to require replacing the bolt before further flight. The NPRM 
also proposed to prohibit installing certain bolts on any helicopter 
unless it has passed the proposed inspections. The proposed 
requirements were intended to detect an unairworthy bolt and prevent 
failure of a bolt, release of a T/R blade, and subsequent loss of 
control of the helicopter.
    The NPRM was prompted by AD No. 2013-0009, dated January 11, 2013, 
issued by EASA, which is the Technical Agent for the Member States of 
the European Union, to correct an unsafe condition for Agusta Model 
A109C, A109K2, A109E, and A119 helicopters, all serial numbers. EASA 
advises that cracks were reported in bolts, P/N 109-8131-09-1, 
installed on a Model A109K2 and a Model A109E helicopter. EASA further 
states that investigations conducted by Agusta revealed the cracks were 
in the same area of the bolts and corresponded with corrosion pits. 
EASA specified that this condition, if not detected and corrected, 
could cause damage to, or loss of, a T/R blade, possibly resulting in 
loss of control of the helicopter.

Comments

    We gave the public the opportunity to participate in developing 
this AD, but we did not receive any comments on the NPRM (78 FR 69595, 
November 20, 2013).

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.

Interim Action

    We consider this AD to be an interim action. If final action is 
later identified, we might consider additional rulemaking.

Related Service Information

    AgustaWestland issued Bollettino Tecnico (BT) No. 109-135 for Model 
A109C helicopters, BT No. 109EP-125 for Model A109E helicopters, BT No. 
109K-55 for Model A109K2 helicopters, and BT No. 119-052 for Model A119 
helicopters. All of the BTs are dated December 19, 2012. The BTs 
specify to perform a visual inspection of bolt, P/N 109-8131-09-1, in 
accordance with the maintenance manual applicable to the model 
helicopter for condition, corrosion, and nicks. The BTs specify 
replacement of the bolt if there is any damage, even if minor, or if 
there is missing cadmium plating in the central part of the bolt. The 
BTs state that if a crack is not revealed from the visual inspection, 
then to perform a liquid penetrant inspection. The BTs further specify 
repeating the visual inspection of the bolts at intervals specific to 
the model helicopter. The BTs state the results of the inspections must 
be communicated to AgustaWestland.

Costs of Compliance

    We estimate this AD affects 132 helicopters of U.S. Registry. We 
estimate that operators may incur the following costs in order to 
comply with this AD. We estimate it will take 2 work-hours to perform 
the initial visual and liquid penetrant inspections and 1 work-hour to 
perform each recurring visual inspection at an average labor cost of 
$85 per work-hour. Based on these figures, it will cost about $170 to 
perform the initial inspections and about $85 to perform each recurring 
visual inspection. A replacement bolt will cost approximately $1,067; 
no additional labor cost is expected for replacement.

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 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.
