ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Bombardier, Inc. Model CL–600–2A12 

(CL–601) and CL–600–2B16 (CL–601– 

3A, CL–601–3R, and CL–604 Variants) 

airplanes. This AD was prompted by 

reports of jamming/malfunctioning of 

the left-hand engine thrust control 

mechanism. This AD requires modifying 

the left-hand engine upper core-cowl. 

We are issuing this AD to prevent 

jamming/malfunctioning of the lefthand engine thrust control mechanism, 

which could lead to loss of control of 

the airplane. 

DATES: This AD becomes effective April 

24, 2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of April 24, 2013.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on June 21, 2012 (77 FR 37342). 

That NPRM proposed to correct an 

unsafe condition for the specified 

products. The Mandatory Continuing 

Airworthiness Information (MCAI) 

states: 

There have been several reported incidents 

of jamming/malfunctioning of the left hand 

(L/H) engine thrust control mechanism on 

the affected aeroplanes. The investigation has 

shown that an improperly stowed or 

dislodged upper core-cowl-door Hold Open 

Rod, can impede a Fuel Control Unit (FCU) 

function by obstructing the movement of the 

FCU actuating lever arm, hence rendering the 

L/H engine thrust control inoperable. 

Due to the engine’s orientation, the subject 

FCU fouling is limited only to the L/H engine 

installation on the affected twin engine 

powered aeroplanes; however the potential 

hazard of any in-flight engine shut down 

caused by jammed engine fuel control lever 

is a safety concern that warrants mitigating 

action. 

In order to help alleviate the possibility of 

an in-flight engine shut down due to the 

subject fouling of the FCU lever by the corecowl-door Hold Open Rod, Bombardier has 

issued three Service Bulletins to [modify the 

L/H engine upper core cowl by] install[ing] 

a new bracket at the L/H engine upper corecowl-door location. This [Canadian] directive 

is issued to mandate the incorporation of the 

Service Bulletins 604–71–005, 601–0609 or 

605–71–002, as applicable on the affected 

aeroplanes. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

have considered the comment received. 

Request To Revise Unsafe Condition 

Bombardier, Inc. requested that we 

revise the end of the unsafe condition 

sentence in the SUMMARY section and 

paragraph (e) of the NPRM (77 FR 


wreier-aviles on DSK5TPTVN1PROD with RULES
17074 Federal Register / Vol. 78, No. 54 / Wednesday, March 20, 2013 / Rules and Regulations 

37342, June 21, 2012) to say, ‘‘which 

could lead to loss of thrust control of 

left hand engine’’ instead of ‘‘which 

could lead to loss of control of the 

airplane.’’ Bombardier, Inc. provided no 

justification for this request. 

We disagree with the request to revise 

the unsafe condition in this final rule 

because loss of thrust control of the left 

hand engine can lead to the loss of 

control of the airplane. We have not 

changed the AD in this regard. 

Conclusion 

We reviewed the available data, 

including the comment received, and 

determined that air safety and the 

public interest require adopting the AD 

as proposed—except for minor editorial 

changes. We have determined that these 

minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (77 FR 

37342, June 21, 2012) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (77 FR 37342, 

June 21, 2012). 

Costs of Compliance 

We estimate that this AD will affect 

407 products of U.S. registry. We also 

estimate that it will take about 3 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 $203 per 

product. Where the service information 

lists required parts costs that are 

covered under warranty, we have 

assumed that there will be no charge for 

these parts. As we do not control 

warranty coverage for affected parties, 

some parties may incur costs higher 

than estimated here. Based on these 

figures, we estimate the cost of this AD 

to the U.S. operators to be $186,406, or 

$458 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD docket. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Operations office between 9 a.m. 

and 5 p.m., Monday through Friday, 

except Federal holidays. The AD docket 

contains the NPRM (77 FR 37342, June 

21, 2012), the regulatory evaluation, any 

comments received, and other 

information. The street address for the 

Docket Operations office (telephone 

(800) 647–5527) is in the ADDRESSES

section. Comments will be available in 

the AD docket shortly after receipt.

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Rolls-Royce Deutschland Ltd & Co KG 

(RRD) Tay 611–8 turbofan engines. This 

AD requires inspection and 

replacement, if necessary, of affected 

bolts. This AD was prompted by a 

quality review determination that bolts 

with reduced material properties may 

have been installed in some engines. We 

are issuing this AD to prevent 

uncontained turbine disc fracture and 

damage to the airplane. 

DATES: This AD becomes effective April 

24, 2013.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on November 13, 2012 (77 FR 

67582). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The Mandatory Continuing 

Airworthiness Information states: 

The results of a recent quality review of 

low pressure turbine (LPT) stage 1 static air 

seal and high pressure turbine (HPT) stage 1 

air seal support bolts identified that, before 

installation, those bolts may have not been 

inspected. As a consequence, bolts with 

reduced material properties may have been 

installed in some engines. 

This condition, if not detected and 

corrected, could lead to failure of a bolt, 

potentially causing turbine disc fracture and 

release of high-energy debris, possibly 

resulting in damage to the aeroplane and/or 

injury to the occupants. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (77 

FR 67582, November 13, 2012). 

However, we changed paragraph (e) of 

this AD by removing the reporting 

requirement because that requirement is 

not necessary to correct the unsafe 

condition. 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed (77 FR 67582, November 

13, 2012). 

Costs of Compliance 

Based on the service information, we 

estimate that this AD affects about 20 

engines of U.S. registry. We also 

estimate that it will take about 4 hours 

per product to comply with this AD. 

The average labor rate is $85 per hour. 

Required parts will cost about $1,848 

per engine. Based on these figures, we 

estimate the cost of the AD on U.S. 

operators to be $43,760.
