AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all 

Bombardier, Inc. Model CL–600–2C10 

(Regional Jet Series 700, 701, & 702) 

airplanes; Model CL–600–2D15 

(Regional Jet Series 705) airplanes; and 

Model CL–600–2D24 (Regional Jet 

Series 900) airplanes. This AD was 

prompted by reports of aileron control 

stiffness. This AD requires revising the 

maintenance program to incorporate the 

discard task for outboard wing aileron 

pulleys. We are issuing this AD to 

prevent aileron control stiffness during 

flight, which could result in reduced 

controllability of the airplane. 

DATES: This AD becomes effective April 

4, 2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of April 4, 2012.

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 8, 2011 

(76 FR 69161). That NPRM proposed to 

correct an unsafe condition for the 

specified products. The MCAI states: 

A number of reports of aileron control 

stiffness have been received on Bombardier 

Regional Jet aeroplanes. Bombardier has 

reviewed the current maintenance tasks for 

the aileron control system and determined 

that an additional maintenance task is 

required. 

This directive mandates revision of the 

approved maintenance schedule to 

incorporate the discard task for outboard 

wing aileron pulleys to prevent aileron 

control stiffness during flight which could 

result in reduced controllability of the 

aeroplane. 

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 

considered the comment received. The 

commenter, Air Line Pilots Association, 

International, supports the NPRM (76 

FR 69161, November 8, 2011). 

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 (76 FR 

69161, November 8, 2011) for correcting 

the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (76 FR 69161, 

November 8, 2011). 

Costs of Compliance 

We estimate that this AD will affect 

398 products of U.S. registry. We also 

estimate that it will take about 1 workhour per product to comply with the 

basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Based on these figures, we estimate the 

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

be $33,830, or $85 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 this proposed regulation: 

1. Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866; 


tkelley on DSK3SPTVN1PROD with RULES
12174 Federal Register / Vol. 77, No. 40 / Wednesday, February 29, 2012 / Rules and Regulations 

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 (76 FR 69161, 

November 8, 2011), 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 all 

DASSAULT AVIATION Model 

MYSTERE-FALCON 50 airplanes. This 

AD was prompted by reports of cracking 

of the flap tracks. This AD requires 

revising the maintenance program to 

include revised airworthiness 

limitations. We are issuing this AD to 

prevent cracking of the flap tracks, 

which could lead to flap asymmetry and 

loss of control of the airplane. 

DATES: This AD becomes effective April 

4, 2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD

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 2, 2011 (76 FR 

67633). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

The Maintenance Procedure (MP) 57–607, 

related to non destructive check of the flap 

tracks 2 and 5, has been introduced thru 

revision 4 (01/2009) of section 5–10 of the 

Recommended Maintenance Schedules 

chapter of the Aircraft Maintenance 

Documentation. 

After the implementation of this MP cracks 

have been detected in service. 

* * * * * 

Cracking of the flap tracks could lead to 

flap asymmetry and loss of control of 

the airplane. The required actions 

include revising the maintenance 

program to include ‘‘Non-Destructive 

Check of Flap Tracks 2 and 5,’’ 

Maintenance Procedure 57–607, of 

Chapter 5–40, ‘‘Airworthiness 

Limitations,’’ of the Dassault Falcon 50/ 

50EX Maintenance Manual, Revision 21, 

dated June 2011. 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 

received no comments on the NPRM 

(76 FR 67633, November 2, 2011) or on 

the determination of the cost to the 

public. 

Explanation of Change Made to This 

AD 

We have revised the document 

citation for the service information 

referenced throughout this AD. 

Conclusion 

We reviewed the relevant data and 

determined that air safety and the 

public interest require adopting the AD 

with the change described previously— 

except for minor editorial changes. We 

have determined that these minor 

changes: 

• Are consistent with the intent that 

was proposed in the NPRM (76 FR 

67633, November 2, 2011) for correcting 

the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (76 FR 67633, 

November 2, 2011). 

Costs of Compliance 

We estimate that this AD will affect 

250 products of U.S. registry. We also 

estimate that it will take about 1 workhour per product to comply with the 

basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Based on these figures, we estimate the 

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

be $21,250, or $85 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 this proposed regulation: 

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.
