[Docket No. FAA-2017-1081; Product Identifier 2017-SW-090-AD]
RIN 2120-AA64


Airworthiness Directives; AgustaWestland S.p.A. Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
AgustaWestland S.p.A. (AgustaWestland) Model AW189 helicopters. This 
proposed AD would require replacing the tail plane lower fitting with 
an improved tail plane lower fitting. This proposed AD is prompted by 
reports of cracks on the tail plane fittings of Model AW189 
helicopters. The actions of this proposed AD are intended to correct an 
unsafe condition on these products.

DATES: We must receive comments on this proposed AD by July 23, 2018.

ADDRESSES: You may send comments by any of the following methods:
     Federal eRulemaking Docket: Go to http://www.regulations.gov. Follow the online instructions for sending your 
comments electronically.

Discussion

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD No. 2016-0161, dated August 8, 2016, 
to correct an unsafe condition for Leonardo Helicopters (previously 
Finmeccanica S.p.A, AgustaWestand) Model AW189 helicopters. EASA 
advises that some cracks have been reported in-service on the tail 
plane fitting of AW189 helicopters following an onset of abnormal play. 
According to EASA, this condition, if not detected and corrected, could 
jeopardize structural integrity of the helicopter. EASA further advises 
that Leonardo Helicopters developed a tail plane lower fitting with an 
improved design (part number 8G0000P00511). Accordingly, EASA AD No. 
2016-0161 requires repetitive inspections of the tail plane lower 
fitting assembly until the improved tail plane lower fitting is 
installed.
    Because the FAA is in the process of updating AgustaWestland's name 
changes to Finmeccanica S.p.A. and then to Leonardo Helicopters on its 
FAA type certificate, this proposed AD specifies AgustaWestland as the 
type certificate holder.

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 its AD. We are 
proposing this AD because we evaluated all known relevant information 
and determined that an unsafe condition is likely to exist or develop 
on other products of the same type design.

Related Service Information

    We reviewed Leonardo Helicopters Bollettino Tecnico (BT) No. 189-
038, Revision B, dated October 13, 2016, which specifies repetitively 
inspecting the tail plane assembly for a crack.
    We also reviewed BT No. 189-070, Revision A, dated October 13, 
2016, which provides instructions for replacing the tail plane lower 
fitting with the improved tail plane lower fitting, retromodification 
part number (P/N) 8G0000P00511.

Proposed AD Requirements

    This proposed AD would require, within 50 hours time-in-service 
(TIS), replacing the tail plane fitting with tail plane 
retromodification kit P/N 8G0000P00511.

Differences Between This Proposed AD and the EASA AD

    The EASA AD requires inspecting the tail plane lower fitting for 
play within 50 flight hours and thereafter at intervals not to exceed 
25 flight hours. If a crack or other damage exists, the EASA AD 
requires the improved tail plane lower fitting be installed within 10 
flight hours. If no crack exists, the EASA AD requires that the 
improved tail plane lower fitting be installed within 200 flight hours 
or 2 months, whichever occurs first. This proposed AD would not require 
inspections and would require installing the improved tail plane lower 
fitting within 50 hours TIS.

Costs of Compliance

    We estimate that this proposed AD would affect 2 helicopters of 
U.S. Registry and that labor costs average $85 a work-hour. Based on 
these estimates, we expect that replacing the tail plane lower fitting 
with an improved tail plane lower fitting would require 64 work-hours 
and parts would cost $15,424 for a total cost of $20,864 per helicopter 
and $41,728 for the U.S. fleet.

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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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, I certify this proposed regulation:
    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

[[Page 23829]]

    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 proposed AD and placed it in the AD docket.
