14648 Federal Register / Vol. 78, No. 45 / Thursday, March 7, 2013 / Rules and Regulations 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Airbus Model A310–204, –222, –304, 

–322, and –324 airplanes. This AD was 

prompted by the manufacturer reclassifying slat extension eccentric bolts 

as principle structural elements (PSE) 

with replacement due at or before newly 

calculated fatigue life limits. This AD 

requires replacing slat extension 

eccentric bolts and associated washers 

with new slat extension eccentric bolts 

and washers. We are issuing this AD to 

prevent fatigue cracking, which could 

result in the loss of structural integrity 

of the airplane. 

DATES: This AD becomes effective April 

11, 2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of April 11, 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 19, 2012 (77 FR 

69391). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The Mandatory Continuing 

Airworthiness Information (MCAI) 

states: 

Slat extension eccentric bolts have been 

reclassified as Principal Structural Elements 

(PSE). As a result, associated fatigue lives 

will be published in the Airbus A310 

Airworthiness Limitation Section (ALS) Part 

1 and bolts must be replaced at or before 

their calculated fatigue lives. 

Failure to replace the bolts within the new 

fatigue life limits constitutes an unsafe 

condition. 

For the reasons explained above, this 

[European Aviation Safety Agency (EASA)] 

AD requires: 

—for A310–300 aeroplanes, the replacement 

of slat extension eccentric bolts, Part 

Number (P/N) A57844015200, with slat 

extension eccentric bolts P/N 

A57844015204 at the slat 2 tracks 4 and 7 

and slat 3 track 8 positions on both Left 

Hand (LH) and Right Hand (RH) wings, and 

—for A310–300 and A310–200 aeroplanes 

that incorporate Airbus modification 

04809, the replacement of slat extension 

eccentric bolts, P/N A57843624200 and 

associated washers P/N A57844016200, 

with slat extension eccentric bolts P/N 

A57843624202 and washers P/N 

A57844391200 at the slat 2 track 5 

position, on both LH and RH wings. 

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 (77 

FR 69391, November 19, 2012) 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—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 

69391, November 19, 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 69391, 

November 19, 2012). 

Costs of Compliance 

We estimate that this AD will affect 1 

product of U.S. registry. We also 

estimate that it will take about 9 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 $25,250 

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 

$26,015, or $26,015 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 69391, 

November 19, 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
