AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are superseding an 

existing airworthiness directive (AD) 

that applies to the products listed above. 

This AD results from mandatory 

continuing airworthiness information 

(MCAI) originated 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: 

Prompted by a reported in-service event, 

EASA issued AD 2009–0084 to prevent 

unwanted movement of pilot- or co-pilot seat 

in the horizontal direction which is 

considered as potentially unsafe, especially 

during the takeoff phase when the speed of 

the aeroplane is greater than 100 knots and 

until landing gear retraction. 

* * * * * 

Uncommanded movement of the pilot 

and co-pilot seats during takeoff or 

landing could interfere with the 

operation of the airplane and, as a 

result, could cause loss of control of the 

airplane. We are issuing this AD to 

require actions to correct the unsafe 

condition on these products. 

DATES: This AD becomes effective April 

26, 2011. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain other publications listed in 

this AD as of April 26, 2011. 

The Director of the Federal Register

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 December 1, 2010 (75 FR 

74665), and proposed to supersede AD 

2009–11–09, Amendment 39–15919 (74 

FR 25399, May 28, 2009). That NPRM 

proposed to correct an unsafe condition 

for the specified products. The MCAI 

states: 

Prompted by a reported in-service event, 

EASA issued AD 2009–0084 [which 

corresponds to FAA AD 2009–11–09] to 

prevent unwanted movement of pilot- or copilot seat in the horizontal direction which 

is considered as potentially unsafe, 

especially during the takeoff phase when the 

speed of the aeroplane is greater than 100 

knots and until landing gear retraction. 

AD 2009–0084 required the deactivation of 

the electrical power of SOGERMA pilot seats 

P/N 2510112 series and co-pilot seats P/N 

2510113 series. Optional intermediate 

actions were also provided by AD 2009–0084 

to allow partial or full restoration of seat 

adjustment functionality. 

Since AD 2009–0084 was issued, a 

permanent solution has been developed that 

terminates the de-activation requirement and 

invalidates the intermediate actions. 

Consequently, this AD retains 

requirements of EASA AD 2009–0084, which 

is superseded, and requires implementing the 

terminating action. In addition, this AD 

prohibits the (re)installation of unmodified 

pilot- and co-pilot seats on any aeroplane 

that has been modified in accordance with 

the requirements of this AD. 

Uncommanded movement of the pilot 

and co-pilot seats during takeoff or 

landing could interfere with the 

operation of the airplane and, as a 

result, could cause loss of control of the 

airplane. You may obtain further 

information by examining the MCAI in 

the AD docket. 

Relevant Service Information 

Since issuance of the NPRM, Airbus 

has issued Mandatory Service Bulletin 

A310–25–2205, Revision 01, dated 

November 19, 2010. This revision does 

not require any additional work. The 

actions described in this service 

information are intended to correct the 

unsafe condition identified in the 

MCAI. We have updated this final rule 

to refer to Airbus Mandatory Service 

Bulletin A310–25–2205, Revision 01, 

dated November 19, 2010. We added a 

new paragraph (n) of this AD to provide 

credit for doing actions before the 

effective date of this AD in accordance 

with Airbus Mandatory Service Bulletin 

A310–25–2205, dated August 31, 2009, 

for Airbus Model A310 series airplanes. 

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 

with the changes described previously. 


Emcdonald on DSK2BSOYB1PROD with RULES
15806 Federal Register / Vol. 76, No. 55 / Tuesday, March 22, 2011 / Rules and Regulations 

We determined that these changes will 

not increase the economic burden on 

any operator or increase the scope of the 

AD. 

Differences Between This AD and the 

MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. But 

we might have found it necessary to use 

different words from those in the MCAI 

to ensure the AD is clear for U.S. 

operators and is enforceable. In making 

these changes, we do not intend to differ 

substantively from the information 

provided in the MCAI and related 

service information. 

We might also have required different 

actions in this AD from those in the 

MCAI in order to follow our FAA 

policies. Any such differences are 

highlighted in a NOTE within the AD. 

Costs of Compliance 

Based on the service information, we 

estimate that this AD affects about 132 

products of U.S. registry. 

The actions that are required by AD 

2009–11–09 and retained in this AD 

take about 2 work-hours per product, at 

an average labor rate of $85 per work 

hour. Based on these figures, the 

estimated cost of the currently required 

actions is $170 per product. 

We estimate that it would take about 

2 work-hours per product to comply 

with the new basic requirements of this 

AD. The average labor rate is $85 per 

work-hour. Required parts would cost 

about $5,000 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 costs. 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 the 

AD on U.S. operators to be $704,880, or 

$5,340 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 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 the NPRM, 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.

Identifier 2009–NM–080–AD; Amendment

RIN 2120–AA64 

Airworthiness Directives; The Boeing 

Company Model 737–600, –700, –700C, 

–800, –900, and –900ER Series 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: The FAA is superseding an 

existing airworthiness directive (AD), 

which applies to all Model 737–600, 

–700, –700C, –800, –900, and –900ER 

series airplanes. That AD currently 

requires repetitive detailed inspections 

of the slat track downstop assemblies to 

verify that proper hardware is installed, 

one-time torquing of the nut and bolt, 

and corrective actions if necessary. This 

new AD also requires replacing the 

hardware of the downstop assembly 

with new hardware of the downstop 

assembly, doing a detailed inspection or 

a borescope inspection of the slat cans 

on each wing and the lower rail of the 

slat main tracks for debris, replacing the 

bolts of the aft side guide with new 

bolts, and removing any debris found in 

the slat can. This AD also removes 

airplanes from the applicability. This 

AD results from reports of parts coming 

off the main slat track downstop 

assemblies. We are issuing this AD to 

prevent loose or missing parts from the 

main slat track downstop assemblies 

from falling into the slat can and 

causing a puncture, which could result 

in a fuel leak and consequent fire. 

DATES: This AD becomes effective April 

26, 2011. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of April 26, 2011.
