SUPPLEMENTARY INFORMATION:

Discussion

On September 13, 2018, at 83 FR 46424, the Federal Register
published the FAA's notice of proposed rulemaking (NPRM), which
proposed to amend 14 CFR part 39 by adding an AD that would apply to
Leonardo Model AW169 helicopters, serial numbers (S/N) 69007, 69009,
69011 to 69019 inclusive, 69021 to 69024 inclusive, 69027, 69032,
69033, 69041, 69045, and 69051. The NPRM proposed to 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. The NPRM also proposed to require replacing
decals on certain internal and external passenger and cockpit windows.
The proposed requirements were intended to ensure the jettisoning of
helicopter emergency exit windows, possibly affecting the evacuation of
occupants after an emergency landing.
The NPRM was prompted by AD No. 2017-0155, dated August 23, 2017,
issued by EASA, which is the Technical Agent for the Member States of
the European Union, to correct an unsafe condition for Leonardo Model
AW169 helicopters, S/N 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 AW189 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.

Comments

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

FAA's Determination

These helicopters have been approved by EASA and are approved for
operation in the United States. Pursuant to the FAA's bilateral
agreement with the European Union, EASA has notified the FAA of the
unsafe condition described in its AD. The FAA is issuing this AD
because the FAA 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 designs and that air
safety and the public interest require adopting the AD requirements as
proposed.

Related Service Information Under 1 CFR Part 51

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

Differences Between This AD and the EASA AD

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

Costs of Compliance

The FAA estimates that this AD affects 1 helicopter of U.S.
Registry and that labor costs average $85 a work-hour. Based on these
estimates, the FAA expects that 24 work-hours are needed to replace the
decal, seal, filler wedges, and handle of each emergency exit window
installed in cockpit doors and the cabin. Parts 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 AD may be covered under warranty, thereby reducing the cost impact
on affected individuals. The FAA does not control warranty coverage by
Leonardo. Accordingly, the FAA has included all costs in this 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.
The FAA is 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


This AD will not have federalism implications under Executive Order
13132. This 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 above, I certify this AD:
1. Is not a ``significant regulatory action'' under Executive Order
12866,
2. Will not affect intrastate aviation in Alaska, and
3. 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.
The FAA prepared an economic evaluation of the estimated costs to
comply with this AD and placed it in the AD docket.
