AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above. This proposed 

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: 

* * * some structural areas have been 

identified for which existing recommended 

SB (service bulletin) needs to be rendered 

mandatory. 

As a consequence, and because it has been 

shown that the torque applied to the tension 

bolts connecting the beam (stringer 49) to the 

forward and aft beam extension at FR11 and 

FR17 may be insufficient, this AD renders 

mandatory the replacement of those tension 

bolts, in order to limit the risks of damage or 

corrosion of the specified areas. 

Damage or corrosion of the specified 

areas could result in reduced structural 

integrity of the airplane. The proposed 

AD would require actions that are 

intended to address the unsafe 

condition described in the MCAI. 

DATES: We must receive comments on 

this proposed AD by May 29, 2007. 

ADDRESSES: You may send comments by 

any of the following methods: 

• DOT Docket Web Site: Go to 

http://dms.dot.gov and follow the 

instructions for sending your comments

SUPPLEMENTARY INFORMATION: 

Streamlined Issuance of AD 

The FAA is implementing a new 

process for streamlining the issuance of 

ADs related to MCAI. This streamlined 

process will allow us to adopt MCAI 

safety requirements in a more efficient 

manner and will reduce safety risks to 

the public. This process continues to 

follow all FAA AD issuance processes to 

meet legal, economic, Administrative 

Procedure Act, and Federal Register 

requirements. We also continue to meet 

our technical decision-making 

responsibilities to identify and correct 

unsafe conditions on U.S.-certificated 

products. 

This proposed AD references the 

MCAI and related service information 

that we considered in forming the 

engineering basis to correct the unsafe 

condition. The proposed AD contains 

text copied from the MCAI and for this 

reason might not follow our plain 

language principles. 

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments about 

this proposed AD. Send your comments 

to an address listed under the 

ADDRESSES section. Include ‘‘Docket No. 

FAA–2007–28017; Directorate Identifier 

2007–NM–005–AD’’ at the beginning of 

your comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this proposed AD. We will 

consider all comments received by the 

closing date and may amend this 

proposed AD based on those comments. 

We will post all comments we 

receive, without change, to http:// 

dms.dot.gov, including any personal 

information you provide. We will also 

post a report summarizing each 

substantive verbal contact we receive 

about this proposed AD. 

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directive 2006–0367, 

dated December 5, 2006 (referred to 

after this as ‘‘the MCAI’’), to correct an 

unsafe condition for the specified 

products. The MCAI states: 

During the A310 life extension exercise 

performed by Airbus, the Airlines 

Representatives and the Airworthiness 

Authorities, some structural areas have been 

identified for which existing recommended 

SB (service bulletin) needs to be rendered 

mandatory. 


jlentini on PROD1PC65 with PROPOSALS
20786 Federal Register / Vol. 72, No. 80 / Thursday April 26, 2007 / Proposed Rules 

As a consequence, and because it has been 

shown that the torque applied to the tension 

bolts connecting the beam (stringer 49) to the 

forward and aft beam extension at FR11 and 

FR17 may be insufficient, this AD renders 

mandatory the replacement of those tension 

bolts, in order to limit the risks of damage or 

corrosion of the specified areas. 

Damage or corrosion of the specified 

areas could result in reduced structural 

integrity of the airplane. You may obtain 

further information by examining the 

MCAI in the AD docket. 

Relevant Service Information 

Airbus has issued Service Bulletin 

A310–53–2045, Revision 05, dated July 

20, 2006. The actions described in this 

service information are intended to 

correct the unsafe condition identified 

in the MCAI. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with the State of 

Design Authority, we have been notified 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all pertinent 

information and determined an unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

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 proposed 

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 

proposed AD. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 29 products of U.S. registry. 

We also estimate that it would take 

about 9 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $80 per work-hour. Required 

parts would cost about $886 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 

proposed AD on U.S. operators to be 

$46,574, or $1,606 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 proposed AD 

would not have federalism implications 

under Executive Order 13132. This 

proposed AD would 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); 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 proposed AD and placed it in the 

AD docket. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Safety. 

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

2. The FAA amends § 39.13 by adding 

the following new AD: 

AIRBUS: Docket No. FAA–2007–28017; 

Directorate Identifier 2007–NM–005–AD. 

Comments Due Date 

(a) We must receive comments by May 29, 

2007. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Airbus Model A310–

203, A310–204, A310–222, A310–304, A310–

322, and A310–324 airplanes, certificated in 

any category, manufacturing serial numbers 

283 through 434 inclusive. Airplanes which 

have received application of Airbus Service 

Bulletin A310–53–2045 at original issue up 

to Revision 05 are not affected by this AD. 

Subject 

(d) Fuselage. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

During the A310 life extension exercise 

performed by Airbus, the Airlines 

Representatives and the Airworthiness 

Authorities, some structural areas have been 

identified for which existing recommended 

SB (service bulletin) needs to be rendered 

mandatory. 

As a consequence, and because it has been 

shown that the torque applied to the tension 

bolts connecting the beam (stringer 49) to the 

forward and aft beam extension at FR11 and 

FR17 may be insufficient, this AD renders 

mandatory the replacement of those tension 

bolts, in order to limit the risks of damage or 

corrosion of the specified areas. 

Damage or corrosion of the specified areas 

could result in reduced structural integrity of 

the airplane. 

Actions and Compliance 

(f) Unless already done, do the following 

actions at the applicable time specified in 

paragraph (f)(1) or (f)(2) of this AD: Rework 

the structure between frame 11 and frame 17 

of the nose landing gear well of the fuselage
