Airworthiness Directives; Airbus Model 

A320 Series Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

Airbus Model A320 series airplanes. 

This AD requires replacing the carbon 

fiber reinforced plastic (CFRP) actuator 

fittings of the rudder with aluminum 

actuator fittings and doing related 

investigative and corrective actions. 

This AD results from rupture of a CFRP 

actuator fitting during maintenance. We 

are issuing this AD to prevent rupture 

of a rudder actuator fitting, which could 

result in reduced controllability of the 

airplane. 

DATES: This AD becomes effective April 

27, 2007. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of April 27, 2007. 

ADDRESSES: You may examine the AD 

docket on the Internet at http://

of Transportation, 400 Seventh Street,

AD.

SUPPLEMENTARY INFORMATION: 

Examining the Docket 

You may examine the airworthiness 

directive (AD) docket on the Internet at 

http://dms.dot.gov or in person at the 

Docket Management Facility office 

between 9 a.m. and 5 p.m., Monday 

through Friday, except Federal holidays.

(telephone (800) 647–5227) is located on 

the plaza level of the Nassif Building at 

the street address stated in the 

ADDRESSES section. 

Discussion 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to certain Airbus Model A320 

series airplanes. That NPRM was 

published in the Federal Register on 

December 15, 2006 (71 FR 75432). That 

NPRM proposed to require replacing the 

carbon fiber reinforced plastic (CFRP) 

actuator fittings of the rudder with 

aluminum actuator fittings and doing 

related investigative and corrective 

actions. 

Comments 

We provided the public the 

opportunity to participate in the 

development of this AD. We have 

considered the comments received. 

Support for the NPRM 

Airbus supports the NPRM. 

Request To Revise Discussion Section 

In the Discussion section of the 

NPRM, we stated that investigation 

revealed that the CFRP actuator fittings 

cannot sustain limit loads resulting from 

ground gust conditions due to design of 

the fitting. Airbus requests that we 

revise that statement to clarify that the 

CFRP actuator fittings ‘‘on the rudder 

side’’ cannot sustain limit 

‘‘compression’’ loads resulting from 

ground gust conditions due to design of 

the fitting. We agree with Airbus’

statement. However, we have not 

changed the AD in this regard, since the 

Discussion section is not retained in the 

final rule. 

Clarification of Alternative Method of 

Compliance (AMOC) Paragraph 

We have revised this action to clarify 

the appropriate procedure for notifying 

the principal inspector before using any 

approved AMOC on any airplane to 

which the AMOC applies. 

Conclusion 

We have carefully reviewed the 

available data, including the comments 

received, and determined that air safety 

and the public interest require adopting 

the AD with the change described 

previously. We have determined that 

this change will neither increase the 

economic burden on any operator nor 

increase the scope of the AD. 

Costs of Compliance 

This AD affects about 38 airplanes of 

U.S. registry. The required action takes 

about 100 work hours per airplane, at an 

average labor rate of $80 per work hour. 

Required parts cost about $6,310 per 

airplane. Based on these figures, the 

estimated cost of the AD for U.S. 

operators is $543,780, or $14,310 per 

airplane. 

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 


sroberts on PROD1PC70 with RULES
13686 Federal Register / Vol. 72, No. 56 / Friday, March 23, 2007 / Rules and Regulations 

that is likely to exist or develop on 

products identified in this rulemaking 

action. 

Regulatory Findings 

We have 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. 

See the ADDRESSES section for a location 

to examine the regulatory evaluation.

Standard Instrument Approach 

Procedures, Weather Takeoff 

Minimums; Miscellaneous 

Amendments 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: This amendment establishes, 

amends, suspends, or revokes Standard 

Instrument Approach Procedures 

(SIAPs) and/or Weather Takeoff 

Minimums for operations at certain 

airports. These regulatory actions are 

needed because of the adoption of new 

or revised criteria, or because of changes 

occurring in the National Airspace 

System, such as the commissioning of 

new navigational facilities, addition of 

new obstacles, or changes in air traffic 

requirements. These changes are 

designed to provide safe and efficient 

use of the navigable airspace and to 

promote safe flight operations under 

instrument flight rules at the affected 

airports. 

DATES: This rule is effective March 23, 

2007. The compliance date for each 

SIAP and/or Weather Takeoff 

Minimums is specified in the 

amendatory provisions. 

The incorporation by reference of 

certain publications listed in the 

regulations is approved by the Director 

of the Federal Register as of March 23, 

2007.
