it back ON. 

Actions and Compliance 

(e) Unless already done, do the following 

actions: 

(1) To prevent the shut-off valve from 

remaining partially closed when the selector 

is turned to the ON position, due to the 

possibility of excess friction in the fuel shutoff valve causing deflection of the push pull 

cable, accomplish the inspection and rework 

instructions in Alpha Aviation Service 

Bulletin (SB) No. AA–SB–28–2002, dated 

June 28, 2006, within 25 hours time-inservice (TIS) after the effective date of this 

AD. 

(2) If the fuel shut-off valve cable is bent, 

replace the cable per SB No. AA–SB–28–

2002, before further flight. 

(3) If the force required to operate the fuel 

shut-off valve exceeds the limits specified in 

SB No. AA–SB–28–002, dated June 28, 2006, 

rework or replace the valve as required, per 

SB No. AA–SB–28–002, dated June 28, 2006, 

before further flight.

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 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–2006–26491; Directorate Identifier 

2006–CE–76–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 because of 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 Civil Aviation Authority of New 

Zealand, which is the airworthiness 


sroberts on PROD1PC70 with PROPOSALS
Federal Register / Vol. 72, No. 4 / Monday, January 8, 2007 / Proposed Rules 677 

authority for New Zealand, has issued 

AD DCA/R2000/12, dated June 29, 2006 

(referred to after this as ‘‘the MCAI’’), to 

correct an unsafe condition for the 

specified products. The MCAI states: 

To prevent fuel system leaks inspect the 

bronze/brass hollow threaded fuel line 

fittings for type and leaks, per Avions Pierre 

Robin Service Bulletin (SB) No. 86. Replace 

leaking Type 1 fuel line fittings with Type 2 

fittings, per SB No. 86, before further flight. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

Avions Pierre Robin (current type 

certificate responsibility with Alpha 

Aviation Design Limited) has issued 

Avions Pierre Robin Service Bulletin 

No. 86, dated July 30, 1980. The actions 

described in this service information are 

intended to correct the unsafe condition 

identified in the MCAI. 

FAA’s Determination and Requirements 

of the 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 this State of 

Design Authority, they have notified us 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all 

information and determined the unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Differences Between This Proposed 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 

described in a separate paragraph of the 

proposed AD. These requirements, if 

ultimately adopted, will take 

precedence over the actions copied from 

the MCAI. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 10 products of U.S. registry. 

We also estimate that it would take 

about 1 work-hour per product to 

comply with the proposed AD. The 

average labor rate is $80 per work-hour. 

Required parts would cost about $100 

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 

$1,800, or $180 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.

Such corrosion may lead to subsequent 

fatigue cracking of the parts affected, 

reducing the aircraft structural integrity, 

which may in turn lead to structural failure 

and/or loss of some control surface. 

The proposed AD would require actions 

that are intended to address the unsafe

Discussion 

The National Agency of Civil Aviation 

(ANAC), which is the aviation authority 

for Brazil, has issued AD No.: 2006–10–

01, dated October 25, 2006 (referred to 

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

unsafe condition for the specified 

products. The MCAI states: 

It has been found cases of corrosion at 

regions of Wings-to-Fuselage attachments, 

Vertical Stabilizer to Fuselage attachments, 

Rib 1 Half-wing and Passenger Seat Tracks. 

Such corrosion may lead to subsequent 

fatigue cracking of the parts affected, 

reducing the aircraft structural integrity, 

which may in turn lead to structural failure 

and/or loss of some control surface. 

You may obtain further information by 

examining the MCAI in the AD docket. 

The MCAI requires: 

Inspection for corrosion at regions of 

Wings-to Fuselage attachments, Vertical 

Stabilizer to Fuselage attachments, Rib 1 

Half-wing and Passenger Seat Tracks; and if 

applicable, removal of the detected corrosion. 

Relevant Service Information
