rulemaking.

Background

    EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2019-0136, dated June 11, 2019 (EASA
AD 2019-0136), to correct an unsafe condition for Leonardo S.p.A.
(formerly Finmeccanica Helicopter Division, AgustaWestland) Model AW189
helicopters. EASA advises of the identification of misleading
information in the AW189 RFM Emergency procedure associated with the
``1(2) FUEL LOW'' caution message. In particular, the procedure at
issue instructs the pilot to land as soon as practicable within 20
minutes. However, this remaining flight time is guaranteed only if a
constant torque value of 50% is maintained. The correct time limit
depends on the fuel consumption at different engine power settings.
Accordingly, EASA AD 2019-0136 requires amending section 3 of the AW189
RFM, ``Emergency and malfunction procedures,'' informing all flight
crews, and thereafter, operating the helicopter accordingly. This
condition, if not addressed, could result in the wrong estimation of
the remaining flight time in a low fuel condition, possibly resulting
in an uncommanded engine in-flight shut-down and forced landing, with
consequent damage to the helicopter or injury to occupants.
    EASA initially issued EASA AD 2019-0103, dated May 9, 2019 (EASA AD
2019-0103), to address this unsafe condition. EASA issued EASA AD 2019-
0136 to supersede EASA AD 2019-0103 to require using the corrected
amendment of the AW189 RFM.

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 about the
unsafe condition described in its AD. The FAA is proposing this AD
after evaluating all known relevant information and determining that
the unsafe condition described previously is likely to exist or develop
on other helicopters of the same type design.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed AW189--RFM, Document No. 189G0290X002, Record of
Temporary Revisions, TR No. 3-1, Revision A, dated May 24, 2019 (TR 3-1
Rev A). TR 3-1 Rev A specifies remaining flight times (minutes) based
on TQ value (%) if the XFEED is closed or if the XFEED is open with
both fuel pumps ON. TR 3-1 Rev A also specifies that the remaining
flight times (minutes) are further reduced if the XFEED is open, both
fuel pumps are ON and one tank has emptied, and the 2 engines are
supplied from the remaining tank.
    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 in This NPRM

    This proposed AD would require revising page 3-118 of Section 3,
Emergency and Malfunction, of the existing RFM for your helicopter to
add remaining flight times (minutes) based on TQ value (%) and
conditions that further reduce the remaining flight times.

Differences Between This Proposed AD and the EASA AD

    EASA AD 2019-0136 requires revising the existing RFM for your
helicopter within 14 days, whereas this proposed AD would require that
action within 14 hours time-in-service after the effective date of this
AD instead. EASA AD 2019-0136 requires removing the RFM changes
previously required by EASA AD 2019-0103, whereas this proposed AD
would not.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would
affect 4 helicopters of U.S. Registry. Labor rates are estimated at $85
per work-hour. Based on these numbers, the FAA estimates the following
costs to comply with this proposed AD.
    Revising the existing RFM for your helicopter would take about 0.25
work-hour for an estimated cost of $21 per helicopter and $84 for the
U.S. fleet.

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 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) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
