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 (AD) 
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 20, 
2020.

Discussion

    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 
aircraft models.
    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.

FAA's Determination

    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
----------------------------------------------------------------------------------------------------------------
               Labor cost                   Parts cost         Cost per product         Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 6 work-hours x $85 per hour = Up                $0  Up to $510................  Up to $5,100.
 to $510.
----------------------------------------------------------------------------------------------------------------

    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.

Regulatory Findings

    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 
government.
    For the reasons discussed above, I certify this proposed 
regulation:
    (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 Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.

Sec.  39.13   [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

Leonardo S.p.A.: Docket No. FAA-2020-0460; Product Identifier 2018-
SW-078-AD.

(a) Comments Due Date

    The FAA must receive comments by July 20, 2020.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to the Leonardo S.p.A. helicopters identified in 
paragraphs (c)(1) and (2) of this AD, certificated in any category, 
equipped with an affected part defined as internal emergency exit 
handle, part number (P/N) 8G9500L00151, and external emergency exit 
handle, P/N 8G9500L00251.
    (1) Model AW169 helicopters, all serial numbers.
    (2) Model AW189 helicopters, all serial numbers, except those

(d) Subject

    Joint Aircraft Service Component (JASC) Code 5600, Windows.

(e) Reason

    This AD was prompted by a report of a broken extrusion rubber 
window seal; an investigation determined the likely cause was 
excessive tension of the string applied during the installation of 
an affected emergency exit handle. The FAA is issuing this AD to 
address this condition, which, if not addressed, could result in an 
excessive load required to release the emergency exit window, 
possibly resulting in delayed evacuation of helicopter occupants 
during an emergency.
