Airworthiness Directives; BRPPowertrain GmbH & Co KG Rotax 

Reciprocating Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: We are superseding an 

existing airworthiness directive (AD) for 

all 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 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. 

DATES: This AD is effective August 27, 

2013. 

We must receive any comments on 

this AD by September 26, 2013.

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. 

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 


ehiers on DSK2VPTVN1PROD with RULES
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. 

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. 

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.

Aviation Regulations (14 CFR part 39) as 

follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

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

§ 39.13 [Amended] 

■ 2. The FAA amends § 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.

(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 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.

[Docket No. 30912; Amdt. No. 3547] 

Standard Instrument Approach 

Procedures, and Takeoff Minimums 

and Obstacle Departure Procedures; 

Miscellaneous Amendments 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: 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 

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.

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 

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
