SUPPLEMENTARY INFORMATION: Discussion On April 4, 2013, we issued AD 2013– 07–12, amendment 39–17416 (78 FR 22166, April 15, 2013), for certain BRPPowertrain GmbH & Co KG Rotax model 912 F2; 912 F3; 912 F4; 912 S2; 912 S3; 912 S4; 914 F2; 914 F3; and 914 F4 reciprocating engines. That AD required a one-time visual inspection for excessive oil or carbon deposits on the 2⁄3 spark plug center and grounding electrodes, and if found, replacement of the cylinder head before further flight. PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 That AD resulted from a report of certain cylinder heads not manufactured to proper specification. We issued that AD to prevent excessive oil consumption, which could result in an in-flight engine shutdown, forced landing, and damage to the airplane. Actions Since AD Was Issued Since we issued AD 2013–07–12 (78 FR 22166, April 15, 2013), we received a report that additional engine cylinder heads are likely to be affected. In addition, some affected cylinder head assemblies, part number (P/N) 623682 and P/N 623687, were supplied as spares between January 31, 2013 and May 28, 2013. Also, since we issued AD 2013–07–12, the European Aviation Safety Agency (EASA) has issued AD 2013–0117–E, dated May 30, 2013, which supersedes and retains the requirements of EASA AD 2013–0055– E and expands the applicability to include all model 912 and 914 engines. Relevant Service Information We reviewed BRP-Powertrain GmbH & Co KG Rotax Aircraft Engines Mandatory Alert Service Bulletin (MASB) No. ASB–912–062, Revision 2 and ASB–914–044, Revision 2 (provided as one document), dated May 29, 2013. The service information describes procedures for inspecting cylinder head assemblies for evidence of excessive oil consumption. FAA’s Determination We are issuing this AD because we evaluated all the relevant information 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 a one-time visual inspection of the center and grounding electrodes of both top and bottom spark plugs on cylinder 2⁄3 for unusual deposits and to replace, before further flight, those cylinder heads not manufactured to proper specification. 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 of the short compliance E:\FR\FM\12AUR1.SGM 12AUR1 48796 Federal Register / Vol. 78, No. 155 / Monday, August 12, 2013 / Rules and Regulations time requirement. Therefore, we find that notice and opportunity for prior public comment are impracticable and 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 we did not provide you with notice and an opportunity to provide your comments before it becomes effective. However, we invite you to send any written data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA– 2013–0263; Directorate Identifier 2013– NE–12–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those comments. We will post all comments we receive, without change, to http:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD. ehiers on DSK2VPTVN1PROD with RULES Costs of Compliance We estimate that this AD affects about 197 engines installed on airplanes of U.S. registry. We also estimate that it would take about 2 hours per engine to inspect a cylinder head assembly. 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 $33,490. 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. 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. VerDate Mar<15>2010 14:50 Aug 09, 2013 Jkt 229001 Regulatory Findings 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 that this AD: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, (2) Is not a ‘‘significant rule’’ under 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends part 39 of the Federal Aviation Regulations (14 CFR part 39) as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

(d) Unsafe Condition This AD was prompted by a report that additional engine cylinder heads are likely to be affected. We are issuing this AD to prevent excessive oil consumption, which could result in an in-flight engine shutdown, forced landing, and damage to the airplane. (e) Compliance Comply with this AD within the compliance times specified, unless already done. (1) Within 5 flight hours or 20 days after the effective date of this AD, whichever occurs first, perform a one-time visual inspection of the center and grounding electrodes of both top and bottom spark plugs on cylinder 2 and cylinder 3, for unusual deposits of excessive oil or carbon deposits. Any excessive oil or carbon deposits indicate the cylinder head is not manufactured to proper specification and is leaking oil into the combustion chamber. (2) Before further flight, replace cylinder heads not manufactured to proper specification. (3) From the effective date of this AD, installation on an engine of an affected spare cylinder head assembly part number (P/N) 623682 or P/N 623687, supplied by BRPPowertrain between January 31, 2013, and May 28, 2013, is prohibited unless the engine, with the spare cylinder head installed, is test run for at least 20 minutes and the inspection called out in paragraph (e) (1) of this AD is accomplished. If the cylinder head fails the inspection required by paragraph (e) (1) of this AD, remove the cylinder head assembly before further flight. (f) Definitions For the purpose of this AD, unusual deposits (excessive carbon or oil) is when: (1) Carbon is a visual buildup of dark carbon deposits on the center and grounding electrodes as well as the immediate surrounding area, and (2) Excessive oil is a visual buildup indicated by the presence of oil on the center and grounding electrodes as well as the immediate surrounding area, giving a wet appearance.

No. 3547] Standard Instrument Approach Procedures, and Takeoff Minimums and Obstacle Departure Procedures; Miscellaneous Amendments FOR FURTHER INFORMATION CONTACT: Federal Aviation Administration (FAA), DOT. ACTION: Final rule. AGENCY: This rule establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports. DATES: This rule is effective August 12, 2013. The compliance date for each ehiers on DSK2VPTVN1PROD with RULES SUMMARY: VerDate Mar<15>2010 14:50 Aug 09, 2013 Jkt 229001 SIAP, associated Takeoff Minimums, and ODP is specified in the amendatory provisions. The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of August 12, 2013. ADDRESSES: Availability of matter incorporated by reference in the amendment is as follows: For Examination— 1. FAA Rules Docket, FAA Headquarters Building, 800 Independence Avenue SW., Washington, DC 20591; 2. The FAA Regional Office of the region in which the affected airport is located; 3.

Box 25082, Oklahoma City, OK 73125) telephone: (405) 954–4164. SUPPLEMENTARY INFORMATION: This rule amends Title 14, Code of Federal Regulations, Part 97 (14 CFR part 97) by amending the referenced SIAPs. The complete regulatory description of each SIAP is listed on the appropriate FAA Form 8260, as modified by the National Flight Data Center (FDC)/Permanent Notice to Airmen (P–NOTAM), and is incorporated by reference in the amendment under 5 U.S.C. 552(a), 1 CFR part 51, and § 97.20 of Title 14 of the Code of Federal Regulations. The large number of SIAPs, their complex nature, and the need for a PO 00000 Frm 00003 Fmt 4700 Sfmt 4700 48797 special format make their verbatim publication in the Federal Register expensive and impractical. Further, airmen do not use the regulatory text of the SIAPs, but refer to their graphic depiction on charts printed by publishers of aeronautical materials. Thus, the advantages of incorporation by reference are realized and publication of the complete description of each SIAP contained in FAA form documents is unnecessary. This amendment provides the affected CFR sections and specifies the types of SIAP and the corresponding effective dates. This amendment also identifies the airport and its location, the procedure and the amendment number. The Rule This amendment to 14 CFR part 97 is effective upon publication of each separate SIAP as amended in the transmittal. For safety and timeliness of change considerations, this amendment incorporates only specific changes contained for each SIAP as modified by FDC/P–NOTAMs. The SIAPs, as modified by FDC P– NOTAM, and contained in this amendment are based on the criteria contained in the U.S. Standard for Terminal Instrument Procedures (TERPS). In developing these changes to SIAPs, the TERPS criteria were applied only to specific conditions existing at the affected airports. All SIAP amendments in this rule have been previously issued by the FAA in a FDC NOTAM as an emergency action of immediate flight safety relating directly to published aeronautical charts. The circumstances which created the need for all these SIAP amendments requires making them effective in less than 30 days. Because of the close and immediate relationship between these SIAPs and safety in air commerce, I find that notice and public procedure before adopting these SIAPs are impracticable and contrary to the public interest and, where applicable, that good cause exists for making these SIAPs effective in less than 30 days. Conclusion The FAA has determined that this regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. It, therefore— (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866; (2) is not a ‘‘significant rule’’ under DOT regulatory Policies and Procedures (44 FR 11034; February 26, 1979); and (3) does not warrant preparation of a regulatory E:\FR\FM\12AUR1.SGM 12AUR1

912 S2; 912 S3; 912 S4; 914 F2; 914 F3; and 914 F4 reciprocating 
engines. That AD required a one-time visual inspection for excessive 
oil or carbon deposits on the cylinder No. 2 and No. 3 (\2/3\) spark 
plug center and grounding electrodes, and if found, replacement of the 
cylinder head before further flight. This AD was prompted by a report 
that additional engine cylinder heads are likely to be affected. We are 
issuing this AD to prevent excessive oil consumption, which could 
result in an in-flight engine shutdown, forced landing, and damage to 
the airplane.

SUPPLEMENTARY INFORMATION: 

Discussion

    On April 4, 2013, we issued AD 2013-07-12, amendment 39-17416 (78 
FR 22166, April 15, 2013), for certain BRP-Powertrain GmbH & Co KG 
Rotax model 912 F2; 912 F3; 912 F4; 912 S2; 912 S3; 912 S4; 914 F2; 914 
F3; and 914 F4 reciprocating engines. That AD required a one-time 
visual inspection for excessive oil or carbon deposits on the \2/3\ 
spark plug center and grounding electrodes, and if found, replacement 
of the cylinder head before further flight. That AD resulted from a 
report of certain cylinder heads not manufactured to proper 
specification. We issued that AD to prevent excessive oil consumption, 
which could result in an in-flight engine shutdown, forced landing, and 
damage to the airplane.

Actions Since AD Was Issued

    Since we issued AD 2013-07-12 (78 FR 22166, April 15, 2013), we 
received a report that additional engine cylinder heads are likely to 
be affected. In addition, some affected cylinder head assemblies, part 
number (P/N) 623682 and P/N 623687, were supplied as spares between 
January 31, 2013 and May 28, 2013. Also, since we issued AD 2013-07-12, 
the European Aviation Safety Agency (EASA) has issued AD 2013-0117-E, 
dated May 30, 2013, which supersedes and retains the requirements of 
EASA AD 2013-0055-E and expands the applicability to include all model 
912 and 914 engines.

Relevant Service Information

    We reviewed BRP-Powertrain GmbH & Co KG Rotax Aircraft Engines 
Mandatory Alert Service Bulletin (MASB) No. ASB-912-062, Revision 2 and 
ASB-914-044, Revision 2 (provided as one document), dated May 29, 2013. 
The service information describes procedures for inspecting cylinder 
head assemblies for evidence of excessive oil consumption.

FAA's Determination

    We are issuing this AD because we evaluated all the relevant 
information 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 a one-time visual inspection of the center and 
grounding electrodes of both top and bottom spark plugs on cylinder \2/
3\ for unusual deposits and to replace, before further flight, those 
cylinder heads not manufactured to proper specification.

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 of 
the short compliance

[[Page 48796]]

time requirement. Therefore, we find that notice and opportunity for 
prior public comment are impracticable and 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 we did not provide you with notice and an opportunity to 
provide your comments before it becomes effective. However, we invite 
you to send any written data, views, or arguments about this AD. Send 
your comments to an address listed under the ADDRESSES section. Include 
``Docket No. FAA-2013-0263; Directorate Identifier 2013-NE-12-AD'' at 
the beginning of your comments. We specifically invite comments on the 
overall regulatory, economic, environmental, and energy aspects of this 
AD. We will consider all comments received by the closing date and may 
amend this AD because of those comments.
    We will post all comments we receive, without change, to  http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

    We estimate that this AD affects about 197 engines installed on 
airplanes of U.S. registry. We also estimate that it would take about 2 
hours per engine to inspect a cylinder head assembly. 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 $33,490.

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.
    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

    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 that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under 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.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends part 39 of the Federal Aviation 
Regulations (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 removing airworthiness directive (AD) 
2013-07-12, Amendment 39-17416 (78 FR 22166, April 15, 2013) and adding 
the following new AD:

2013-15-19 BRP-Powertrain GmbH & Co. KG (formerly BRP-Rotax GmbH & 
Co KG, Bombardier-Rotax GmbH & Co. KG, and Bombardier-Rotax GmbH): 
Amendment 39-17535; Docket No. FAA-2013-0263; Directorate Identifier 
2013-NE-12-AD.

(a) Effective Date

    This AD is effective August 27, 2013.

(b) Affected ADs

    This AD supersedes AD 2013-07-12, Amendment 39-17416 (78 FR 
22166, April 15, 2013)

(c) Applicability

    This AD applies to the following BRP Powertrain GmbH & Co KG 
Rotax reciprocating engines:
    (1) Rotax 912F from serial number (S/N) 4,413.013 to S/N 
4,413.019, inclusive.
    (2) Rotax 912S, from S/N 4,924.468 to S/N 4,924.543, inclusive.
    (3) Rotax 914F, from S/N 4,421.156 to S/N 4,421.177, inclusive.
    (4) All Rotax 912F, 912S, and 914F engines with cylinder head 
assembly, part number (P/N) 623682 or P/N 623687, supplied by BRP-
Powertrain between January 31, 2013, and May 28, 2013, installed.

(d) Unsafe Condition

    This AD was prompted by a report that additional engine cylinder 
heads are likely to be affected. We are issuing this AD to prevent 
excessive oil consumption, which could result in an in-flight engine 
shutdown, forced landing, and damage to the airplane.

(e) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.
    (1) Within 5 flight hours or 20 days after the effective date of 
this AD, whichever occurs first, perform a one-time visual 
inspection of the center and grounding electrodes of both top and 
bottom spark plugs on cylinder 2 and cylinder 3, for unusual 
deposits of excessive oil or carbon deposits. Any excessive oil or 
carbon deposits indicate the cylinder head is not manufactured to 
proper specification and is leaking oil into the combustion chamber.
    (2) Before further flight, replace cylinder heads not 
manufactured to proper specification.
    (3) From the effective date of this AD, installation on an 
engine of an affected spare cylinder head assembly part number (P/N) 
623682 or P/N 623687, supplied by BRP-Powertrain between January 31, 
2013, and May 28, 2013, is prohibited unless the engine, with the 
spare cylinder head installed, is test run for at least 20 minutes 
and the inspection called out in paragraph (e) (1) of this AD is 
accomplished. If the cylinder head fails the inspection required by 
paragraph (e) (1) of this AD, remove the cylinder head assembly 
before further flight.

(f) Definitions

    For the purpose of this AD, unusual deposits (excessive carbon 
or oil) is when:
    (1) Carbon is a visual buildup of dark carbon deposits on the 
center and grounding electrodes as well as the immediate surrounding 
area, and
    (2) Excessive oil is a visual buildup indicated by the presence 
of oil on the center and grounding electrodes as well as the 
immediate surrounding area, giving a wet appearance.

(g) Alternative Methods of Compliance (AMOCs)

    The Manager, Engine Certification Office, may approve AMOCs for 
this AD. Use the procedures found in 14 CFR 39.19 to make your 
request.
