14 CFR Part 39
[Docket No. FAA-2020-0460; Product Identifier 2018-SW-078-AD]
Airworthiness Directives; Leonardo S.p.A. Helicopters
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
SUMMARY: The FAA proposes to adopt a new airworthiness directive
for Leonardo S.p.A. Model AW169 and AW189 helicopters. This proposed AD
was prompted by a report of a broken extrusion rubber window seal. This
proposed AD would require installation of a reinforcement around the
rubber filler wedge where the extrusion rubber window seal meets the
door's emergency exit handle. The FAA is proposing this AD to address
the unsafe condition on these products.
DATES: The FAA must receive comments on this proposed AD by July
ADDRESSES: You may send comments, using the procedures found in
11.43 and 11.45, by any of the following methods:

The European Aviation Safety Agency (now European Union Aviation
Safety Agency) (EASA), which is the Technical Agent for the Member
States of the European Union, has issued EASA AD 2018-0197, dated
September 5, 2018 (referred to after this as "the MCAI"), to correct
an unsafe condition for all Leonardo S.p.A. Model AW169 helicopters and
certain Leonardo S.p.A Model AW189 helicopters. EASA advises of a
broken extrusion rubber window seal, part number A417AF001WB. According
to EASA, an investigation determined that the damage to the rubber
filler wedge of the rubber window seal could have been caused by the
excessive tension of the string applied during the installation of an
affected emergency exit handle. EASA advises that this condition, if
not corrected, could result in an excessive load to release the
emergency exit window, possibly resulting in delayed evacuation of
helicopter occupants during an emergency. EASA states that, due to
design similarities, the same unsafe condition could exist or develop
on certain Model AW189 helicopters. To correct this condition, EASA AD
2018-0197 requires installation of a reinforcement around the rubber
filler wedge where the extrusion rubber window seal meets the door's
emergency exit handle.

Related Service Information Under 1 CFR Part 51
Leonardo Helicopters has issued Alert Service Bulletin 169-094,
Revision A, dated August 13, 2018, and Alert Service Bulletin 189-170,
dated July 25, 2018. This service information describes procedures for
installation of a reinforcement around the rubber filler wedge where
the extrusion rubber window seal meets the door's emergency exit
handle. These documents are distinct since they apply to different
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.
These products have been approved by the aviation authority of
another country, and are approved for operation in the United States.
Pursuant to the FAA's bilateral agreement with the State of Design
Authority, the FAA has been notified of the unsafe condition described
in the MCAI and service information referenced above. The FAA is
proposing this AD after evaluating all the relevant information and
determining the unsafe condition described previously is likely to
exist or develop on other products of these same type designs.
Proposed Requirements of This NPRM
This proposed AD would require accomplishing the actions specified
in the service information described previously.
Costs of Compliance
The FAA estimates that this proposed AD affects 10 helicopters of
U.S. registry. The FAA estimates the following costs to comply with
this proposed AD:
Estimated Costs for Required Actions
|Up to 6 work-hours x $85 per
hour = Up to $510
Up to $510
Up to $5,100
According to the manufacturer, some
or all of the costs of this
proposed AD may be covered under warranty, thereby reducing the cost
impact on affected individuals. The FAA does not control warranty
coverage for affected individuals. As a result, the FAA has included
all known 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.
The FAA has 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
For the reasons discussed above, I certify this proposed
(1) Is not a "significant regulatory action" under Executive
(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.
