AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (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 airworthiness authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as fatigue damage with a 

crack propagation through the fastener 

line of the wing shroud box bottom 

panel, resulting in panel detachment 

and potential injuries to persons on the 

ground. We are issuing this AD to 

require actions to correct the unsafe 

condition on these products. 

DATES: This AD becomes effective May 

18, 2007. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of May 18, 2007.

SUPPLEMENTARY INFORMATION: 

Discussion 

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 

allow 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 AD references the MCAI and 

related service information that we 

considered in forming the engineering 

basis to correct the unsafe condition. 

The AD contains text copied from the 

MCAI and for this reason might not 

follow our plain language principles. 

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 January 26, 2007 (72 FR 

3771). That NPRM proposed to require 

performing a one-time detailed 

inspection of the shroud box bottom 

panel for cracks, fasteners missing or 

loose, damage, and marks; and applying 

all applicable corrective actions. The 

MCAI states that an A330 operator has 

reported a shroud box bottom panel 

missing during routine inspection. The 

same panel detached from an A330 

aircraft during take-off, causing damages 

to the surrounding structure and to the 

Trimmable Horizontal Stabilizer (THS) 

tip fairing. Preliminary inspection has 

shown that the blind rivets used to 

attach the panel worked loose causing 

the panel to suffer fatigue damage with 

a crack propagation through the fastener 

line resulting in panel detachment. To 

avoid potential injuries to persons on 

ground, the MCAI mandates a one time 

detailed visual inspection of the shroud 

box bottom panel for cracks in the panel 

and for missing and loose fasteners, and 

repair if necessary. 

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. 

Clarification of Service Bulletin 

Reference 

The ‘‘Relevant Service Information’’ 

section of the NPRM, and paragraph (g) 

of the NPRM refer to Airbus Service 

Bulletin A330–57A3092, February 3, 

2006, as one of the appropriate sources 

of service information to do the actions 

in the NPRM. However, in paragraph (e) 

of the NPRM, we inadvertently referred 

to Airbus Service Bulletin A330– 

57A3792, dated February 3, 2006. We 

have revised paragraph (e) of this AD 

accordingly. 

Conclusion 

We reviewed the available data, and 

determined that air safety and the 

public interest require adopting the AD 

with the change described previously. 

We determined that this change 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 a U.S. 

court of law. 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 

described in a separate paragraph of the 

AD. These requirements, if any, take 

precedence over the actions copied from 

the MCAI. 

Costs of Compliance 

We estimate that this AD will affect 

27 products of U.S. registry. We also 

estimate that it will take about 2 workhours per product to comply with this 

AD. The average labor rate is $80 per 

work-hour. Based on these figures, we 


cprice-sewell on PRODPC61 with RULES
18564 Federal Register / Vol. 72, No. 71 / Friday, April 13, 2007 / Rules and Regulations 

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

operators to be $4,320, or $160 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 

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://dms.dot.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–

Adoption of the Amendment 

■ Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 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: 

2007–08–05 Airbus: Amendment 39–15022. 

Docket No. FAA–2007–27013; 

Directorate Identifier 2006–NM–236–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective May 18, 2007. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Airbus Model A330–

200, A330–300, A340–200, and A340–300 

series airplanes, all certified models, all 

serial numbers, certificated in any category, 

on which Airbus Modification 42061 or 

46077 or 53604 has been embodied in 

production and delivered before December 

31, 2005. 

Reason 

(d) The mandatory continuing 

airworthiness information (MCAI) states that 

an A330 operator has reported a shroud box 

bottom panel missing during routine 

inspection. The same panel detached from an 

A330 aircraft during take-off, causing 

damages to the surrounding structure and to 

the Trimmable Horizontal Stabilizer (THS) 

tip fairing. Preliminary inspection has shown 

that the blind rivets used to attach the panel 

worked loose causing the panel to suffer 

fatigue damage with a crack propagation 

through the fastener line resulting in panel 

detachment. To avoid potential injuries to 

persons on ground, the MCAI requires a one 

time detailed visual inspection of the shroud 

box bottom panel for cracks in the panel and 

for missing and loose fasteners, and 

applicable repairs. 

Actions and Compliance 

(e) Unless already done, do the following 

actions. Within the threshold specified in 

paragraphs (e)(1) and (e)(2) of this AD and in 

accordance with the instructions of Airbus 

Service Bulletin A330–57A3092, dated 

February 3, 2006; or Airbus Service Bulletin 

A340–57A4101, dated February 3, 2006; as 

applicable: Perform a one-time detailed 

inspection of the shroud box bottom panel 

for cracks, fasteners missing or loose, 

damage, and marks; and apply all applicable 

corrective actions. Do applicable corrective 

actions before further flight. The inspections 

results, whatever they are, must be reported 

to Airbus. 

(1) For Model A330 airplanes: Whichever 

occurs later between paragraphs (e)(1)(i) and 

(e)(1)(ii) of this AD. 

(i) Prior to the accumulation of 1,200 flight 

cycles or 2,400 flight hours from the first 

flight of the aircraft, whichever occurs first.

SUPPLEMENTARY INFORMATION: 

Streamlined Issuance of AD 

The FAA is implementing a new 

process for streamlining the issuance of 

ADs related to MCAI. The 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 AD references the MCAI and 

related service information that we 

considered in forming the engineering 

basis to correct the unsafe condition. 

The AD contains text copied from the 

MCAI and for this reason might not 

follow our plain language principles. 

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 February 12, 2007 (72 FR 

6500). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

This Airworthiness Directive * * * is 

published in order to maintain the structural 

integrity of the applicable aircraft. The 

Service Bulletin provides life limits for 

critical landing gear components. Failure of 

such items could lead to unsafe conditions. 

The MCAI requires: 

From the effective date of this AD, it is 

mandatory to comply with the requirements 

given in Jetstream Series 3100 and 3200 

Service Bulletin 32–JA981042 Rev 5. Landing 

Gear—Main and Nose Landing Gears—To 

introduce life limitations and provide means 

of establishing total flight cycles since new 

for critical components * * * 

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 

149 products of U.S. registry. We also 

estimate that it will take about 2 workhours per product to comply with basic 

requirements of this AD. The average 

labor rate is $80 per work-hour. Based 

on these figures, we estimate the cost of 

this AD to the U.S. operators to be 

$23,840, or $160 per product.

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
