AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

issued by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

Due to manufacturing problems of BR700– 

710 HP stage 1 and 2 turbine discs it was 

necessary to re-calculate the Declared Safe 

Cyclic Life (DSCL) for all BR700–710 HP 

turbine discs. The analysis concluded that it 

is required to reduce the approved life limits 

for the HP turbine disc part numbers that are 

listed in Table 1 and Table 2 of this AD 

(MCAI). Exceeding the revised approved life 

limits could potentially result in noncontained disc failure. 

We are issuing this AD to preventfailure of the high-pressure turbine 

(HPT) stage 1 and stage 2 discs, 

uncontained engine failure, and damage 

to the airplane. 

DATES: This AD becomes effective 

January 13, 2011.

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 August 23, 2010 (75 FR 

51693). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states that: 

Due to manufacturing problems of BR700– 

710 HP stage 1 and 2 turbine discs it was 

necessary to re-calculate the Declared Safe 

Cyclic Life (DSCL) for all BR700–710 HP 

turbine discs. The analysis concluded that it 

is required to reduce the approved life limits 

for the HP turbine disc part numbers that are 

listed in Table 1 and Table 2 of this AD 

(MCAI). Exceeding the revised approved life 

limits could potentially result in noncontained disc failure. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM or 

on the determination of the cost to the 

public. 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed. 

Costs of Compliance 

Based on the service information, we 

estimate that this AD will affect about 

1,026 BR700–710 engines of U.S. 

registry. We also estimate that no 

additional labor cost will be incurred to 

replace the discs. The average labor rate 

is $85 per work-hour. Required parts 

will cost about $6,000 per disc. Based 

on these figures, we estimate the cost of 

the AD on U.S. operators to be 

$6,156,000. Our cost estimate is 

exclusive of possible warranty coverage. 

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, 


erowe on DSK5CLS3C1PROD with RULES
Federal Register / Vol. 75, No. 236 / Thursday, December 9, 2010 / Rules and Regulations 76625 

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 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. 

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 this AD, the regulatory 

evaluation, any comments received, and 

other information. The street address for 

the Docket Operations office (phone 

(800) 647–5527) is provided in the 

ADDRESSES section. Comments will be 

available in the AD docket shortly after 

receipt.

Reason 

(d) This AD results from mandatory 

continuing airworthiness information 

(MCAI) issued by an aviation authority 

of another country to identify and 

correct an unsafe condition on an 

aviation product. The MCAI states: 

Due to manufacturing problems of BR700– 

710 HP stage 1 and 2 turbine discs it was 

necessary to re-calculate the Declared Safe 

Cyclic Life (DSCL) for all BR700–710 HP 

turbine discs. The analysis concluded that it 

is required to reduce the approved life limits 

for the HP turbine disc part numbers that are 

listed in Table 1 and Table 2 of this AD 

(MCAI). Exceeding the revised approved life 

limits could potentially result in noncontained disc failure. 

We are issuing this AD to prevent 

failure of the HPT stage 1 and stage 2 

discs, uncontained engine failure, and 

damage to the airplane. 

Actions and Compliance 

(e) Unless already done, do the 

following actions. 

(1) Within 30 days after the effective 

date of this AD, or upon accumulating 

the declared safe cyclic life indicated in 

Table 1 or Table 2 of this AD as 

applicable, whichever occurs later, 

initially replace the HPT stage 1 or HPT 

stage 2 discs with serviceable discs. 

(2) Thereafter, upon accumulating the 

declared safe cyclic life indicated in 

Table 1 or Table 2 of this AD, as 

applicable, repetitively replace the HPT 

stage 1 or HPT stage 2 discs with 

serviceable discs. 

FAA AD Differences 

(f) None. 

Alternative Methods of Compliance 

(AMOCs) 

(g) The Manager, Engine Certification 

Office, FAA, has the authority to 

approve AMOCs for this AD, if 

requested using the procedures found in 

14 CFR 39.19.

Standard Instrument Approach 

Procedures, and Takeoff Minimums 

and Obstacle Departure Procedures; 

Miscellaneous Amendments 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: This 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 December 9, 

2010. 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 December 

9, 2010.
