[Docket No. FAA-2016-2042; Directorate Identifier 2016-NE-02-AD;
Amendment 39-18568; AD 2016-13-04]
RIN 2120-AA64
Airworthiness Directives; BRP-Powertrain GmbH & Co KG
Reciprocating Engines
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for certain
BRP-Powertrain GmbH & Co KG Rotax 912 F2, 912 F3, 912 F4, 912 S2, 912
S3, 912 S4, 914 F2, 914 F3, and 914 F4 reciprocating engines. This AD
requires re-identification of the engine model and concurrent
modification of the aircraft to indicate the maximum coolant
temperature limit. This AD was prompted by a design change introduced
by the manufacturer that relocated the engine cylinder head temperature
sensor to a different location and converted it to a coolant
temperature sensor. We are issuing this AD to prevent exceeding engine
coolant temperature limits, which could result in loss of engine
coolant, damage to the engine, and loss of control of the airplane.
DATES: This AD becomes effective July 27, 2016.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of July 27,
2016.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would apply to the specified products. The
NPRM was published in the Federal Register on March 18, 2016 (81 FR
14804). The NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
A design change of the engine cylinder heads was introduced by
BRP-Powertrain in March 2013 which modifies the engine/aircraft
interfaces by substituting the previous cylinder head temperature
(CHT) measurement (limit temperature 135 [deg]C/150 [deg]C) with a
coolant temperature (CT) measurement (limit temperature 120 [deg]C).
The design change was communicated on 15 May 2013 by BRP-
Powertrain Service Instruction (SI) 912-020R7/914-022R7 (single
document) but was not identified by a change of the engine model
designation or of the engine P/N but only through the cylinder head
P/N and the position of the temperature sensor.
Consequently, engines with the new cylinder heads (installed
during production or replaced in-service during maintenance) may be
installed on an aircraft without concurrent modification of that
aircraft, instructions for which should be provided by the type
certificate (TC) holder or the supplemental type certificate (STC)
holder, as applicable. In this case, the coolant temperature with a
maximum engine operating limit of 120 [deg]C (valid for engines
operated with water diluted glycol coolant) is displayed on a CHT
indicator with a typical limit marking (red radial/range) of more
than 120 [deg]C.
You may obtain further information by examining the MCAI in the AD
docket on the Internet at http://www.regulations.gov by searching for
and locating Docket No. FAA-2016-2042.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (81 FR 14804, March 18,
2016).
Conclusion
We reviewed the available data and determined that air safety and
the public interest require adopting this AD as proposed expect for
minor editorial changes. We determined that these changes will not
increase the economic burden on any operator or increase the scope of
this AD.
Related Service Information Under 1 CFR Part 51
BRP-Powertrain GmbH & Co KG has issued Service Bulletin (SB) SB-
912-068/SB-914-049 (one document), dated April 16, 2015. The service
information describes procedures for re-identification of the type
plate for certain BRP-Powertrain GmbH & Co KG Rotax 912 and 914
engines. 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.
Costs of Compliance
We estimate that this AD affects about 40 engines installed on
aircraft of U.S. registry. We also estimate that it will take about 5
hours per engine to inspect and re-identify the type plate. The average
labor rate is $85 per hour. Based on these figures, we estimate the
cost of this AD on U.S. operators to be $17,000.
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue
[[Page 40484]]
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.
We are 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
We determined that this AD will not have federalism implications
under Executive Order 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,
(2) Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation in Alaska to the extent
that it justifies making a regulatory distinction, and
(4) 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.

and 914 F4.
912 S2, 912 S3, and 912 S4................ P/N 413185.
------------------------------------------------------------------------
(d) Reason
This AD was prompted by a design change introduced by the
manufacturer that relocated the engine cylinder head temperature
sensor to a new location and converted it to a coolant temperature
sensor. We are issuing this AD to prevent exceeding coolant
temperature limits, which could result in loss of engine coolant,
damage to the engine, and loss of control of the airplane.
(e) Actions and Compliance
Comply with this AD within 6 months after the effective date of
this AD, unless already done.
(1) For engines with cylinder heads that have a P/N listed in
Figure 1 to paragraph (c) of this AD installed on both position 2
and position 3, change the engine model designation on the engine
type data plate to include a ``-01'' suffix. Use paragraph 3.1.1 of
BRP-Powertrain Service Bulletin (SB) SB-912-068/SB-914-049, dated
April 16, 2015, to make this change.
(2) For engines with only one cylinder head having a P/N listed
in Figure 1 to paragraph (c) of this AD installed in position 2 or
3, do one of the following:
(i) Replace the cylinder head having a P/N listed in Figure 1 to
paragraph (c) of this AD with a P/N 623682 cylinder head on Rotax
912 F2, 912 F3, 912 F4, 914 F2, 914 F3, and 914 F4 engines and with
a P/N 623687 cylinder head on Rotax 912 S2, 912 S3, and 912 S4
engines. If you complete the actions in paragraph (e)(2)(i), no
further action is required. Or,
(ii) Install cylinder heads identified in Figure 1 to paragraph
(c) of this AD on both cylinder head positions 2 and 3 and change
the engine model designation of the engine type data plate in
accordance with paragraph (e)(1) of this AD.
(3) For engines re-identified in accordance with paragraph
(e)(1) or (e)(2)(ii) of this AD, before further flight, modify the
aircraft cockpit instrumentation and related documentation to
indicate a maximum coolant temperature limit of 120 degrees Celsius
using FAA-approved procedures. These re-identified engines remain
eligible for installation on approved aircraft-engine combinations.
(f) Alternative Methods of Compliance (AMOCs)
The Manager, Engine Certification Office, FAA, may approve AMOCs
for this AD. Use the procedures found in 14 CFR 39.19 to make your
request. You may email your request to: [email protected].
