Federal Register Volume 82, Issue 146 (August 1, 2017)

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

SUPPLEMENTARY INFORMATION: 

Discussion

    On April 10, 2017, at 82 FR 17156, 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 Agusta S.p.A. Model 
A109S helicopters. The NPRM proposed to 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 part number 
(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.
    The NPRM was prompted by AD No. 2015-0227, dated November 19, 2015, 
issued by EASA, which is the Technical Agent for the Member States of 
the European Union, to correct an unsafe condition for the 
AgustaWestland S.p.A. Model A109S helicopters. EASA advises of a report 
that the right-hand lower cabin liner of Internal Arrangement P/N 109-
0814-21-101 detached and hit three M/R 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.

Comments

    We gave the public the opportunity to participate in developing 
this AD, but we did not receive any comments on the NPRM.

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 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 the same type design 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. 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.

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.

Costs of Compliance

    We estimate that this AD affects 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 takes 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 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.
