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: 

A failure of fuel pump sealing, due to 

possible incorrect maintenance procedures 

and subsequent testing, caused a fuel leakage 

into the main landing gear bay. Presence of 

fuel vapours in that zone creates a risk of fire 

due to presence of potential ignition sources 

such as electrical equipment and connectors. 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective June 

3, 2010. 

On June 3, 2010, the Director of the 

Federal Register approved the 

incorporation by reference of certain 

publications 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 

mstockstill on DSKH9S0YB1PROD with RULES

Federal Register / Vol. 75, No. 82 / Thursday, April 29, 2010 / Rules and Regulations 22513 

Register on February 19, 2010 (75 FR 

7409). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

A failure of fuel pump sealing, due to 

possible incorrect maintenance procedures 

and subsequent testing, caused a fuel leakage 

into the main landing gear bay. Presence of 

fuel vapours in that zone creates a risk of fire 

due to presence of potential ignition sources 

such as electrical equipment and connectors. 

As a consequence, this new Airworthiness 

Directive (AD) requires a functional check of 

main and stand-by fuel pumps for absence of 

leakage and an update of the Aircraft 

Maintenance Manual (AMM). 

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. 

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 FAA policies. 

Any such differences are highlighted in 

a Note within the AD. 

Costs of Compliance 

We estimate that this AD will affect 

63 products of U.S. registry. We also 

estimate that it will take about 2 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 $10 per 

product. 

Based on these figures, we estimate 

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

to be $11,340 or $180 per product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 40 work-hours and require parts 

costing $7,349, for a total cost of 

$10,749 per product. We have no way 

of determining the number of products 

that may need these actions. 

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 

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 Management Facility 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 Office 

(telephone (800) 647–5527) is in the 

ADDRESSES section. Comments will be 

available in the AD docket shortly after 

receipt.

ACTION: Final rule; request for 

comments. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Model 747–200B series airplanes. This 

AD requires repetitive inspections for 

cracking of the fuselage skin lap joints 

at stringer 6 on the left and right sides 

from station (STA) 340 to STA 400, a 

one-time general visual inspection to 

determine if certain fasteners are 

installed and to determine if service 

repair manual (SRM) repairs or repair 

doublers are installed, and corrective 

actions if necessary. Doing an optional 

modification of the stringer 6 lap joints 

terminates the repetitive inspections for 

the modified area. This AD results from 

reviews done by Boeing, which show 

that airplanes that were modified by 

Boeing to the stretched upper deck 

(SUD) configuration require inspection 

for cracking of the stringer 6 lap joint 

upper-fastener row earlier than 

previously expected. We are issuing this 

AD to detect and correct cracking of the 

stringer 6 lap joints where certain 

external doublers were not installed, 

which could result in rapid 

decompression and loss of structural 

integrity of the airplane. 

DATES: This AD is effective May 14, 

2010. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of May 14, 2010. 

We must receive comments on this 

AD by June 28, 2010.
