14 CFR Part 39

[Docket No. FAA-2018-0057; Product Identifier 2017-SW-119-AD]
RIN 2120-AA64


Airworthiness Directives; Leonardo 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 
certain Leonardo S.p.A. (Leonardo) Model AW169 helicopters. This 
proposed AD would require replacing the seals, filler wedges, and 
handles of each emergency exit window. This proposed AD is prompted by 
a report that a high level of pushing force was required to jettison 
some windows. The actions of this proposed AD are intended to address 
an unsafe condition on these products.

Discussion

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD No. 2017-0155, dated August 23, 
2017, to correct an unsafe condition for Leonardo Model AW169 
helicopters, serial numbers 69007, 69009, 69011 to 69019 inclusive, 
69021 to 69024 inclusive, 69027, 69032, 69033, 69041, 69045, and 69051. 
EASA advises that during scheduled replacement of emergency exit window 
seals on in-service Model AW169 helicopters, an ``excessively high'' 
level of pushing force was required to jettison some windows. Further 
investigation determined that the affected windows were incorrectly 
installed during manufacturing. The installation did not conform to the 
approved drawings during the first installation in the production line. 
According to EASA, due to the similarity in the manufacturing process, 
incorrect window installation may have occurred on Model AW169 
helicopters. EASA states that this condition, if not corrected, could 
prevent the jettisoning of helicopter emergency exit windows, possibly 
affecting the evacuation of occupants after an emergency landing.
    EASA consequently requires replacement of the seal, the non-
metallic channel (filler wedges), and the handle of emergency exit 
windows installed in the cockpit doors and cabin.

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 Under 1 CFR Part 51

    We reviewed Leonardo Service Bulletin No. 169-032, Revision A, 
dated September 8, 2017, which specifies

[[Page 46425]]

replacing the seals, the non-metallic channels, handles, and decals on 
the cockpit doors and cabin emergency exit windows.
    This service information is reasonably available because the 
interested parties have access to it through their normal course of 
business or by the means identified in the ADDRESSES section.

Proposed AD Requirements

    This proposed AD would require within 70 hours time-in-service 
(TIS), replacing the seals and filler wedges on various cockpit and 
passenger windows and replacing certain internal and external window 
straps. This proposed AD also would require replacing decals on certain 
internal and external passenger and cockpit windows.

Differences Between This Proposed AD and the EASA AD

    The EASA AD requires that the corrective actions occur within 70 
hours TIS or 6 months. This proposed AD would require that the 
corrective actions occur within 70 hours TIS.

Costs of Compliance

    We estimate that this proposed AD would affect 1 helicopter of U.S. 
Registry and that labor costs average $85 a work-hour. Based on these 
estimates, we expect that 24 work-hours would be needed to replace the 
decal, seal, filler wedges, and handle of each emergency exit window 
installed in cockpit doors and the cabin. Parts would cost $1,500 for a 
total cost of $3,540 for this helicopter.
    According to Leonardo's service information some of the costs of 
this proposed AD may be covered under warranty, thereby reducing the 
cost impact on affected individuals. We do not control warranty 
coverage by Leonardo. Accordingly, we have included all costs in our 
cost estimate.

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.
