SUPPLEMENTARY INFORMATION:
Discussion
The European Union Aviation Safety Agency (EASA), which is the
Technical Agent for the Member States of the European Community, has
issued EASA
[[Page 59293]]
AD No. 2018-0265R1, dated January 9, 2019 (and corrected January 10,
2019) (referred to after this as ``the MCAI''), to address an unsafe
condition for the specified products. The MCAI states:
A broken exhaust valve has been reported on a non-certified
Rotax 914 UL2-01 engine. Subsequent investigation identified
deviation in the manufacturing process of the affected exhaust
valve.
This condition, if not corrected, could lead to in-flight shut
down, possibly resulting in a forced landing with consequent damage
to the aeroplane and injury to occupants.
Due to similarity of design, this condition may affect also
Rotax 915 iSc3 A, 915 iSc3 B engines and Rotax 914 F2, 914 F3 and
914 F4 engines.
To address this potential unsafe condition, BRP-Rotax issued the
ASB, later revised, providing applicable instructions, and EASA
issued AD 2018-0265-E requiring replacement of affected exhaust
valves, and prohibiting installation thereof on an engine.
Since that [EASA] AD was issued, it has been determined that
only exhaust valve P/N 854113 of certain lot numbers are affected,
and BRP-Rotax revised the ASB accordingly (now at revision 2).
You may obtain further information by examining the MCAI in the AD
docket on the internet at https://www.regulations.gov by searching for
and locating Docket No. FAA-2019-0747.
Related Service Information
The FAA reviewed BRP-Rotax Alert Service Bulletin (ASB) ASB-915 i
A-003R2/ASB-915 i B-003R2/ASB-914-054R2 (single document), dated
December 21, 2018. The ASB describes procedures for replacing the
exhaust valve.
FAA's Determination
This product has been approved by EASA, and is 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 the MCAI and service information
referenced above. The FAA is issuing this AD because it evaluated all
the relevant information provided by EASA and determined the unsafe
condition described previously is likely to exist or develop in other
products of the same type design.
AD Requirements
This AD requires, within 10 flight hours or 3 months after the
effective date of this AD, whichever occurs first, removal from service
of certain exhaust valves and replacement with a part eligible for
installation.
FAA's Justification and Determination of the Effective Date
An unsafe condition exists that requires the immediate adoption of
this AD. The FAA has found that the risk to the flying public justifies
waiving notice and comment prior to adoption of this rule because no
domestic operators use this product. It is unlikely that the FAA will
receive any adverse comments or useful information about this AD from
U.S. operators. Therefore, the FAA finds good cause that notice and
opportunity for prior public comment are unnecessary. In addition, for
this same reason, the FAA finds that good cause exists for making this
amendment effective in less than 30 days.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety and was not preceded by notice and an opportunity for public
comment. However, the FAA invites you to send any written data, views,
or arguments about this final rule. Send your comments to an address
listed under the ADDRESSES section. Include the docket number FAA-2019-
0747 and Product Identifier 2019-NE-26-AD at the beginning of your
comments. The FAA specifically invites comments on the overall
regulatory, economic, environmental, and energy aspects of this final
rule. The FAA will consider all comments received by the closing date
and may amend this final rule because of those comments.
The FAA will post all comments received, without change, to https://www.regulations.gov, including any personal information you provide.
The FAA will also post a report summarizing each substantive verbal
contact received about this final rule.
Regulatory Flexibility Act
The requirements of the Regulatory Flexibility Act (RFA) do not
apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt
a rule without prior notice and comment. Because the FAA has determined
that it has good cause to adopt this rule without notice and comment,
RFA analysis is not required.
Costs of Compliance
The FAA estimates that this AD affects 0 engines installed on
airplanes of U.S. registry.
In the event an affected engine becomes installed on a U.S.-
registered product, the FAA estimates the following costs to comply
with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Replace exhaust valve.............. 6 work-hours x $85 per hour $1,500 $2,010 $0
= $510.
----------------------------------------------------------------------------------------------------------------
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.
This AD is issued in accordance with authority delegated by the
Executive Director, Aircraft Certification Service, as authorized by
FAA Order 8000.51C. In accordance with that order, issuance of ADs is
normally a function of the Compliance and Airworthiness Division, but
during this transition period, the Executive Director has delegated the
authority to issue ADs applicable to engines, propellers, and
associated appliances to the Manager, Engine and Propeller Standards
Branch, Policy and Innovation Division.
Regulatory Findings
This AD will not have federalism implications under Executive Order
[[Page 59294]]
13132. This AD will 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, and
(2) Will not affect intrastate aviation in Alaska.
