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, 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

55T423 (HS 801000–2), or 50U150 (HS 

801000–3) installed. 

(d) Unsafe Condition 

This AD was prompted by an engine 

overspeed event that occurred during taxi 

and resulted in a high-pressure compressor 

surge and tailpipe fire. We are issuing this 

AD to prevent engine overspeed on these 

engines, which could result in an 

uncontained engine failure and damage to 

the airplane. 

(e) Compliance

(h) Definition of Shop Visit 

For the purpose of this AD, a shop visit is 

when the engine is inducted into the shop for 

any maintenance involving the separation of 

pairs of major mating engine flanges (lettered 

flanges). However, the separation of engine 

flanges solely for the purposes of transporting 

the engine without subsequent engine 

maintenance is not an engine shop visit.

ACTION: Final rule; request for 

comments. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for BRPPowertrain GmbH & Co KG Rotax 912 

S2, 912 S3, and 914 F2 reciprocating 

engines. This AD requires performing a 

one-time inspection of the oil system for 

leaks and a torque check of the oil pump 

attachment bolts, and if leaks are 

detected, performing a one-time 

inspection of the oil pump and engine 

valve train, on certain serial number 

(S/N) BRP-Powertrain GmbH & Co KG 

Rotax 912 S2, 912 S3, and 914 F2 

reciprocating engines. This AD was 

prompted by the discovery that during 

engine production, some engines may 

not have had the oil pump attachment 

bolts torqued to specification. We are 

issuing this AD to prevent oil leaks, 


tkelley on DSK3SPTVN1PROD with RULES

SUPPLEMENTARY INFORMATION:

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Emergency AD 2012–0019–E, dated 

January 26, 2012 (referred to after this 

as ‘‘the MCAI’’), to correct an unsafe 

condition for the specified products. 

The MCAI states: 

During a production quality review, a 

deviation in the assembly process of the oil 

pump attachment bolts has been detected, 

which may have resulted in a latent defect 

on a limited number of engines. The affected 

bolts may not have been tightened to the 

correct torque value, i.e. not in accordance 

with the specification. This condition, if not 

corrected, could lead to oil leaks and 

irregularities in the oil supply, possibly 

resulting in uncommanded in-flight engine 

shutdown and forced landing, damage to the 

aeroplane and injury to occupants. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

BRP-Powertrain GmbH & Co KG has 

issued Mandatory ASBs No. ASB–912– 

060 and No. ASB–914–043 (combined 

in one document), dated January 26, 

2012. The actions described in this 

service information are intended to 

correct the unsafe condition identified 

in the MCAI. 

FAA’s Determination and Requirements 

of This AD 

This product has been approved by 

the aviation authority of Austria, and is 

approved for operation in the United 

States. Pursuant to our bilateral 

agreement with the European 

Community, EASA has notified us of 

the unsafe condition described in the 

MCAI and service information 

referenced above. We are issuing this 

AD because we evaluated all 

information provided by EASA and 

determined the unsafe condition exists 

and is likely to exist or develop on other 

products of the same type design. This 

AD requires performing a one-time 

inspection of the oil system for leaks 

and a torque check of the oil pump 

attachment bolts, and if leaks are 

detected, performing a one-time 

inspection of the oil pump and engine 

valve train, on certain S/N BRPPowertrain GmbH & Co KG Rotax 912 

S2, 912 S3, and 914 F2 reciprocating 

engines. 

FAA’s 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 

these engines. Therefore, we determined 

that notice and opportunity for public 

comment before issuing this AD are 

unnecessary and that good cause exists 

for making this amendment effective in 

fewer than 30 days. 

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety, and 

we did not precede it by notice and 

opportunity for public comment. We 

invite you to send any written relevant 

data, views, or arguments about this AD. 

Send your comments to an address 

listed under the ADDRESSES section. 

Include ‘‘Docket No. FAA–2012–0126; 

Directorate Identifier 2012–NE–07–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 with FAA 

personnel concerning this AD. Using the 

search function of the Web site, anyone 

can find and read the comments in any 

of our dockets, including, if provided, 

the name of the individual who sent the 

comment (or signed the comment on 

behalf of an association, business, labor 

union, etc.). You may review the DOT’s 

complete Privacy Act Statement in the 

Federal Register published on April 11, 

2000 (65 FR 19477–78). 

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 


tkelley on DSK3SPTVN1PROD with RULES
12452 Federal Register / Vol. 77, No. 41 / Thursday, March 1, 2012 / Rules and Regulations 

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); and 

3. 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD docket.
