Airworthiness Directives; Various 

Aircraft Equipped With Rotax Aircraft 

Engines 912 A Series Engine 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for various 

aircraft equipped with Rotax Aircraft 

Engines 912 A series engine. This AD 

results from mandatory continuing 

airworthiness information (MCAI) 

issued by the aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as a deviation in the 

manufacturing process of certain part 

number 888164 crankshafts that may 

cause cracks on the surface of the 

crankshaft on the power take off side, 

which could lead to failure of the 

crankshaft support bearing and possibly 

result in an in-flight engine shutdown 

and forced landing. We are issuing this 

AD to require actions to address the 

unsafe condition on these products. 

DATES: This AD is effective January 26, 

2012.

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 AD 2011– 

0224–E, dated November 24, 2011 

(referred to after this as ‘‘the MCAI’’), to 

correct an unsafe condition for the 

specified products. The MCAI states: 

During a production process review, a 

deviation (double side straightening) in the 

manufacturing process of certain Part 

Number (P/N) 888164 crankshafts has been 

detected, which may have resulted in cracks 

on the surface of the crankshaft. Only a few 


pmangrum on DSK3VPTVN1PROD with RULES
Federal Register / Vol. 77, No. 7 / Wednesday, January 11, 2012 / Rules and Regulations 1627 

crankshafts are suspected to have received 

this double side straightening treatment, but 

it has been impossible to identify these by 

individual serial number (s/n). To address 

this safety concern, BRP–Powertrain issued 

Alert Service Bulletin ASB–912–059 and 

ASB–914–042 (single document) with 

instructions to identify and inspect the entire 

batch of crankshafts that could be affected. 

These crankshafts have been installed on a 

limited number of engines, but some 

crankshaft sets have also been shipped as 

spare parts. 

This condition, if not detected and 

corrected, could lead to crack propagation on 

the power take off side of the crankshaft 

journal, possibly resulting in failure of the 

crankshaft support bearing, in-flight engine 

shutdown and forced landing, damage to the 

aeroplane and injury to occupants. 

To correct this potential unsafe condition, 

EASA issued Emergency AD 2011–022–E to 

require the identification and inspection for 

cracks of all affected crankshafts, and 

depending on findings, corrective action. 

Since that AD was issued, it has been 

determined that there are additional affected 

crankshafts, currently known to be installed 

in the ‘UL’ (i.e. non-certified) versions of the 

affected engines. 

For the reason described above, this AD 

retains the requirements of EASA AD 2011– 

0222–E, which is superseded, and expands 

the group of s/n of affected crankshafts, listed 

in Table 1 of this AD. A records check can 

be acceptable to determine the s/n of the 

crankshaft installed on the engine. This AD 

also prohibits installation of any affected 

crankshaft on an engine, or installation of an 

aeroplane of an engine with an affected 

crankshaft installed, unless the crankshaft 

has passed the inspection as required by this 

AD. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

Rotax Aircraft Engines BRP has issued 

Alert Service Bulletin ASB–912–059 

and ASB–914–042 (single document), 

dated November 15, 2011. The actions 

described in this service information are 

intended to correct the unsafe condition 

identified in the MCAI. 

FAA’s Determination and Requirements 

of the AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with this State of 

Design Authority, they have 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 the State of 

Design Authority and determined the 

unsafe condition exists and is likely to 

exist or develop on other products of the 

same type design. 

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 of the short compliance 

time of 4 hours time-in-service, and the 

risk to single-engine airplanes affected. 

Therefore, we determined that notice 

and opportunity for public comment 

before issuing this AD are impracticable 

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–2012–0001; 

Directorate Identifier 2011–CE–041– 

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 will affect 

112 products of U.S. registry. We also 

estimate that it will take about 31 workhours per product to comply with the 

basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Required parts will cost about $5,400 

per product. 

Based on these figures, we estimate 

the cost of the AD on U.S. operators to 

be $899,920, or $8,035 per product. 

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 

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 that 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, 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.

(e) Reason 

This AD was prompted by mandatory 

continuing airworthiness information (MCAI) 

issued by the aviation authority of another 

country to identify and correct an unsafe 

condition on an aviation product. The MCAI 

describes the unsafe condition as a deviation 

(double side straightening) in the 

manufacturing process of certain P/N 888164 

crankshafts that may cause cracks on the 

surface of the crankshaft on the power take 

off side, which could lead to failure of the 

crankshaft support bearing. We are issuing 

this AD to prevent failure of the crankshaft 

support bearing, which could result in engine 

failure and forced landing. 

(f) Actions and Compliance 

Unless already done, do the following 

actions. 

(1) Within 4 hours time-in-service after 

January 26, 2012 (the effective date of this 

AD), inspect the crankshaft for cracks. Do the 

inspection following the Accomplishment

Alert Service Bulletin ASB–912–059 and 

ASB–914–042 (single document), dated 

November 15, 2011. 

(2) If any crack is found during the 

inspection required in paragraph (f)(1) of this 

AD, before further flight, remove the 

crankshaft from service. 

(3) As of January 26, 2012 (the effective 

date of this AD), do not install on any 

airplane an engine equipped with an affected 

P/N 888164 crankshaft listed in paragraph
