[Docket No. FAA-2013-0350; Directorate Identifier 2012-SW-050-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 A119 and AW119 MKII 
helicopters to require inspecting the pilot and co-pilot doors to 
ensure that the windows are properly bonded within the doors. If the 
windows are not properly bonded, the proposed AD would require applying 
bonding to the windows, the seals, and the window frames of the pilot 
and co-pilot doors. This proposed AD is prompted by the loss of a 
pilot-door window during a test flight. The proposed actions are 
intended to ensure the windows do not detach from the doors, 
potentially injuring persons on the ground and damaging the 
helicopter's tailboom and the tail rotor blades.

DATES: We must receive comments on this proposed AD by June 24, 2013.

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

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
No. 2012-0058, dated April 3, 2012, to correct an unsafe condition for 
AgustaWestland Model A119 and AW119 MKII helicopters. EASA advises that 
the pilot-door window detached during a test flight of an AW119 MKII 
helicopter. The occupant was not injured, and the helicopter was not 
damaged.
    According to EASA, an investigation revealed that a ``lack of the 
bonding of the seal both to the window and to the door structure'' 
caused the window's detachment. To address this unsafe condition, 
AugustaWestland issued Bollettino Tecnico (BT) No. 119-47, dated March 
29, 2012, and EASA issued AD No. 2012-0058 to require an inspection of 
the bonding in the pilot and co-pilot door windows and, if there is no 
bonding, applying bonding.
    If this condition is not corrected, it could lead to detachment of 
the windows from the pilot- and co-pilot doors, potentially injuring 
persons on the ground and damaging the helicopter.

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 BT No. 119-47 for all AgustaWestland A119 and AW119 
MKII helicopters, which contains procedures to ensure that the pilot- 
and co-pilot door windows are correctly bonded.

Proposed AD Requirements

    This proposed AD would require, within the next 50 hours time-in-
service (TIS) or within the next five months, whichever comes first, 
inspecting the pilot and co-pilot doors to determine whether there is 
bonding between the seals, the window frames, and the windows in the 
external and internal sides of the seals' junction areas. If no bonding 
exists, before further flight, this proposed AD would require applying 
bonding to the windows, seals, and window frames.

Costs of Compliance

    We estimate that this proposed AD would affect 65 helicopters of 
U.S. Registry and that labor costs would average $85 an hour. Based on 
these estimates, we expect the following costs:
     Inspecting for bonding between the seals and the windows 
in the internal

[[Page 24368]]

and external sides of the junction areas would require 0.5 work-hour 
for a labor cost of about $43. No parts would be needed, so the cost 
for the U.S. fleet would total $2,795.
     Adding the bonding material if needed would require about 
1.5 work-hours for a labor cost of about $128. The cost of materials 
would be negligible.

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.
