flight; however, to avoid inadvertently 

grounding airplanes, this AD requires 

performing those inspections within 14 days 

after the effective date of this AD. 

(2) Repair: Although the MCAI or service 

information does not include a repair 

procedure for cracking, this AD requires the 

repair of any cracking per the FAA, EASA, 

or its delegated agent. 

Other FAA AD Provisions 

(g) The following provisions also apply to 

this AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, International

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 deficiency in compliance 

with 14 CFR 23.967(d). There have been 

instances indicating that production 

aircraft may not have a metal barrier 

between the cabin and the fuel tank bay. 

Lack of a barrier could allow flammable 

fuel vapors to enter the cabin. We are 

issuing this AD to require actions to 

correct the unsafe condition on these 

products. 

DATES: This AD becomes effective April 

3, 2007. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of April 3, 2007.

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 January 5, 2007 (72 FR 481). 

That NPRM proposed to correct an 

unsafe condition for the specified 

products. The MCAI states that there 

have been instances indicating that 

production aircraft may not have a 

metal barrier between the cabin and the 

fuel tank bay. Lack of a barrier could 

allow flammable fuel vapors to enter the 

cabin. The MCAI requires that you, to 

ensure that the aircraft is in compliance 

with 14 CFR 23.967(d), inspect the 

aircraft to determine if a metal barrier is 

installed behind the seats and, if not 

installed, to manufacture and install a 

barrier. 

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 described in a 

separate paragraph of the AD, and take 

precedence over the actions copied from 

the MCAI. 

Costs of Compliance 

We estimate that this AD will affect 

10 products of U.S. registry. We also 

estimate that it will take about 3 workhours per product to comply with this 

AD. The average labor rate is $80 per 

work-hour. Required parts will cost 

about $300 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 parts. 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 

this AD to the U.S. operators to be 

$5,400 or $540 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 

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–

5227) is in the ADDRESSES section. 

Comments will be available in the AD 

docket shortly after receipt.

Reason 

(d) The mandatory continuing 

airworthiness information (MCAI) states that 

there have been instances indicating that 

production aircraft may not have a metal 

barrier between the cabin and the fuel tank 

bay. Lack of a barrier could allow flammable 

fuel vapors to enter the cabin. The MCAI 

requires that, to ensure that the aircraft is in 

compliance with 14 CFR 23.967(d), inspect 

the aircraft to determine if a metal barrier is 

installed behind the seats and, if not 

installed, to manufacture and install a 

barrier. 

Actions and Compliance 

(e) Unless already done, do the following 

actions within the next 100 hours time-inservice or within 6 months after April 3, 2007 

(the effective date of this AD), whichever 

occurs first. 

(1) Inspect the aircraft to determine if a 

metal barrier is installed behind the seats per 

Alpha Aviation Service Bulletin AA–SB–28–

001, dated July 10, 2006. 

(2) If a metal barrier is installed per Alpha 

Aviation Service Bulletin AA–SB–28–001, 

dated July 10, 2006, and (e)(1) of this AD, 

then no further action is required. 

(3) If a metal barrier is not installed, 

manufacture and install a barrier per Alpha 

Aviation Service Bulletin AA–SB–28–001, 

dated July 10, 2006, and Alpha Aviation 

Drawing No. 60–53–119 (page 3 of 3 of the

AGENCY: Federal Aviation 

Administration (FAA), Department of

ACTION: Final rule. 

SUMMARY: The FAA is superseding an 

existing airworthiness directive (AD), 

which applies to certain Fokker Model 

F.28 Mark 0070 and 0100 airplanes. 

That AD currently requires a one-time 

inspection of the sliding members in the 

main landing gear (MLG) for cracking 

and replacement of the sliding members 

with serviceable parts if necessary. This 

new AD adds repetitive magnetic 

particle inspections of the sliding 

members of the MLG for cracking and 

corrective actions as necessary. This AD 

results from inspection findings that 

have shown repetitive inspections are 

needed to establish fleet safety. We are 

issuing this AD to detect and correct 

fatigue cracking of the sliding member, 

which could result in possible 

separation of the MLG from the airplane 

and consequent reduced controllability 

of the airplane upon landing and 

possible injury to passengers. 

DATES: This AD becomes effective April 

3, 2007. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of April 3, 2007. 

On May 19, 2004 (69 FR 19759, April 

14, 2004), the Director of the Federal 

Register approved the incorporation by
