Airplanes 

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) 

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: 

Corrosion damage has been found on the 

aft pressure bulkhead of SAAB 2000 

aeroplanes, located on the rear side of the 

bulkhead at the bottom outboard flange. 

Corrosion damage in this area can become 

the starting point for future crack initiation 

and propagation. 

This condition, if not detected and 

corrected, could affect the structural integrity 

of the aft pressure bulkhead, possibly 

resulting in in-flight decompression of the 

fuselage and injury to occupants. 

* * * * * 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective 

September 30, 2011. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of September 30, 2011.

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 June 1, 2011 (76 FR 31508). 

That NPRM proposed to correct an 

unsafe condition for the specified 

products. The MCAI states: 

Corrosion damage has been found on the 

aft pressure bulkhead of SAAB 2000 

aeroplanes, located on the rear side of the 

bulkhead at the bottom outboard flange. 

Corrosion damage in this area can become 

the starting point for future crack initiation 

and propagation. 

This condition, if not detected and 

corrected, could affect the structural integrity 

of the aft pressure bulkhead, possibly 

resulting in in-flight decompression of the 

fuselage and injury to occupants. 

For the reasons described above, this AD 

requires a detailed visual inspection of the aft 

pressure bulkhead at the bottom outboard 

flange [for corrosion and drain hole] and, 

depending on findings, corrective action. 

Corrective actions include contacting 

the FAA or EASA (or its delegated 

agent) for repair instructions if corrosion 

is found, and drilling a drain hole. 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 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 our FAA 

policies. Any such differences are 

highlighted in a NOTE within the AD. 

Costs of Compliance 

We estimate that this AD will affect 8 

products of U.S. registry. We also 

estimate that it will take about 12 workhours per product to comply with the 

basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Based on these figures, we estimate the 

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

be $8,160, or $1,020 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, 

mstockstill on DSK4VPTVN1PROD with RULES

53302 Federal Register / Vol. 76, No. 166 / Friday, August 26, 2011 / Rules and Regulations 

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

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: 

* * * * * 

The airworthiness limitations applicable to 

Damage Tolerant Airworthiness Limitation 

Items (DT ALI) are currently given in Airbus 

A330 ALI Document reference AI/SE–M4/ 

95A.0089/97, which is approved by the 

European Aviation Safety Agency (EASA) 

and referenced in Airbus Airworthiness 

Limitations Section (ALS) Part 2. 

The issue 17 of Airbus A330 ALI 

Document introduces more restrictive 

maintenance requirements/airworthiness 

limitations. Failure to comply with this issue 

constitutes an unsafe condition. 

This [EASA] AD supersedes EASA AD 

2009–0102 [and retains the requirements 

therein], and requires the implementation of 

the new or more restrictive maintenance 

requirements/airworthiness limitations as 

specified in Airbus A330 ALI Document 

issue 17. 

The unsafe condition is fatigue 

cracking, damage, and corrosion in 

certain structure, which could result in 

reduced structural integrity of the 

airplane. We are issuing this AD to 

require actions to correct the unsafe 

condition on these products. 

DATES: This AD becomes September 30, 

2011. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of September 30, 2011. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain other publication listed in 

this AD as of June 7, 2006 (71 FR 25919,

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 March 22, 2011 (76 FR 

15867), and proposed to supersede AD 

2006–09–07, Amendment 39–14577 (71 

FR 25919, May 3, 2006). That NPRM 

proposed to correct an unsafe condition 

for the specified products. The MCAI 

states: 

The airworthiness limitations are 

distributed in the Airbus A330 Airworthiness 

Limitations Section (ALS). 

The airworthiness limitations applicable to 

Damage Tolerant Airworthiness Limitation 

Items (DT ALI) are currently given in Airbus 

A330 ALI Document reference AI/SE–M4/ 

95A.0089/97, which is approved by the 

European Aviation Safety Agency (EASA) 

and referenced in Airbus Airworthiness 

Limitations Section (ALS) Part 2. 

The issue 17 of Airbus A330 ALI 

Document introduces more restrictive 

maintenance requirements/airworthiness 

limitations. Failure to comply with this issue 

constitutes an unsafe condition. 

This [EASA] AD supersedes EASA AD 

2009–0102 [and retains the requirements 

therein], and requires the implementation of 

the new or more restrictive maintenance 

requirements/airworthiness limitations as 

specified in Airbus A330 ALI Document 

issue 17. 

The unsafe condition is fatigue 

cracking, damage, and corrosion in 

certain structure, which could result in 

reduced structural integrity of the 

airplane. 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 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 our FAA 

policies. Any such differences are 

highlighted in a NOTE within the AD. 

Costs of Compliance 

We estimate that this AD will affect 

about 54 products of U.S. registry. 

The actions that are required by AD 

2006–09–07, Amendment 39–14577 (71 

FR 25919, May 3, 2006), and retained in 

this AD, take about 1 work-hour 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 $85 per product. 

We estimate that it will take about 1 

work-hour per product to comply with
