14 CFR Part 39

[Docket No. FAA-2017-0142; Directorate Identifier 2016-SW-013-AD]
RIN 2120-AA64


Airworthiness Directives; Agusta S.p.A.

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
Agusta S.p.A. Model A109S helicopters. This proposed AD is prompted by 
a report of a cabin liner detaching from the helicopter and hitting the 
main rotor (M/R) blades during flight. This proposed AD would require 
adding limitations to the rotorcraft flight manual (RFM). The proposed 
actions are intended to prevent an unsafe condition on these products.

DATES: We must receive comments on this proposed AD by June 9, 2017.

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.
     Fax: 202-493-2251.
     Mail: Send comments to the U.S. Department of 
Transportation, Docket Operations, M-30, West Building Ground Floor, 
Room W12-140, 1200 New Jersey Avenue SE., Washington, DC 20590-0001.
     Hand Delivery: Deliver to the ``Mail'' address between 9 
a.m. and 5 p.m., Monday through Friday, except Federal holidays.

Discussion

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD No. 2015-0227, dated November 19, 
2015, to correct an unsafe condition for AgustaWestland S.p.A. Model 
A109S helicopters. EASA advises of a report that the right-hand lower 
cabin liner of Internal Arrangement part number (P/N) 109-0814-21-101 
detached and hit three main rotor blades during a landing with the 
right-hand door removed. EASA states that this condition, if not 
corrected, could lead to further occurrences of in-flight lower cabin 
liner detachment, possibly resulting in damage to or loss of control of 
the helicopter. Therefore, the EASA AD requires revising the RFM to 
provide limitations on flights with a passenger cabin sliding door 
opened or removed. EASA considers its AD an interim action and states 
further AD action may follow.

FAA's Determination

    This helicopter has been approved by the aviation authority of 
Italy and is 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 helicopters of the same type design.

Related Service Information

    We reviewed AgustaWestland A109S RFM, Document No. 109G0040A013, 
Issue 2, Revision 3, dated April 23, 2015, which adds several 
limitations regarding flight with a passenger cabin sliding door opened 
or removed.

Proposed AD Requirements

    This proposed AD would require, within 15 hours time-in-service, 
revising the Limitations section of the RFM by inserting a copy of this 
AD or by making pen-and-ink changes to add several limitations: 
Prohibiting flight with a passenger cabin sliding door opened or 
removed for helicopters with Internal Arrangement P/N 109-0814-21-101 
installed; prohibiting flight with a passenger cabin sliding door open 
unless modification P/N 109-0814-35 is installed; prohibiting flight 
with a passenger cabin sliding door open unless the doors are locked; 
establishing a maximum VNE with a passenger cabin sliding 
door opened or removed; establishing a maximum airspeed for opening or 
closing a passenger cabin sliding door during flight; and prohibiting 
instrument flight rule operation with any door opened or removed.

Interim Action

    We consider this proposed AD to be an interim action. The design 
approval holder is currently developing a modification that will 
address the unsafe condition identified in this AD. Once this 
modification is developed, approved, and available, we might consider 
additional rulemaking.

Costs of Compliance

    We estimate that this proposed AD would affect 19 helicopters of 
U.S. Registry. We estimate that operators may incur the following costs 
in order to comply with this AD. At an average labor rate of $85 per 
work-hour, revising the RFM would take about 0.5 work-hour, for an 
estimated cost of $43 per helicopter, or $817 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 (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.
