Airworthiness Directives; Airbus Model 

A330 Airplanes and Model A340–200 

and –300 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 A330 airplanes and 

Model A340–200 and –300 series 

airplanes. This AD requires inspecting 

to determine the part number of certain 

S4- and MZ-type spoiler servo controls 

(SSCs). For certain other airplanes, this 

AD requires inspecting to determine the 

part number of all SSCs. This AD also 

requires replacing any affected SSC with 

a new SSC. This AD results from a new 

load duty cycle defined by the 

manufacturer. Additional fatigue tests 

and calculations done on this basis 

indicated that the spoiler valve 

manifold of the S4-type SSCs, and, on 

certain airplanes, the maintenance cover 

of the MZ-type SSCs, may crack during 

its service life due to pressure impulse 

fatigue. We are issuing this AD to 

prevent fatigue cracking of certain SSCs, 

which could result in hydraulic leakage 

and consequent loss of SSC function 

and loss of the associated hydraulic 

system. These conditions could affect 

all three hydraulic systems, which 

could result in reduced controllability 

of the airplane. 

DATES: This AD becomes effective April 

11, 2007. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of April 11, 2007.

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 A330 

airplanes and Model A340–200 and 

–300 series airplanes. That NPRM was 

published in the Federal Register on 

December 28, 2006 (71 FR 78102). That 

NPRM proposed to require inspecting to 

determine the part number of certain 

S4- and MZ-type spoiler servo-controls 

(SSCs). For certain other airplanes, that 

NPRM proposed to require inspecting to 

determine the part number of all SSCs. 

That NPRM also proposed to require 

replacing any affected SSC with a new 

SSC. 

Comments 

We provided the public the 

opportunity to participate in the 

development of this AD. We received no 

comments on the NPRM or on the 

determination of the cost to the public. 

Conclusion 

We have carefully reviewed the 

available data and determined that air 

safety and the public interest require 

adopting the AD as proposed. 

Costs of Compliance 

This AD affects about 27 airplanes of 

U.S. registry. 

It takes about 1 work hour per 

airplane to accomplish the inspection to 

determine the part number, at an 

average labor rate of $80 per work hour. 

Based on these figures, the estimated 

cost of the inspection required by this 

AD for U.S. operators is $2,160, or $80 

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 


sroberts on PROD1PC70 with RULES
10058 Federal Register / Vol. 72, No. 44 / Wednesday, March 7, 2007 / Rules and Regulations 

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 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.

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 Federal Aviation 

Administration (FAA) amends § 39.13 

by adding the following new 

airworthiness directive (AD): 

2007–05–12 Airbus: Amendment 39–14973. 

Docket No. FAA–2006–26707; 

Directorate Identifier 2006–NM–157–AD. 

Effective Date 

(a) This AD becomes effective April 11, 

2007. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Airbus Model A330–

201, –202, –203, –223, –243, –301, –302, 

–303, –321, –322, –323, –341, –342, and –343 

airplanes; and Model A340–211, –212, –213, 

–311, –312, and –313 airplanes; certificated 

in any category; excluding airplanes on 

which AIRBUS Modification 44670 has been 

embodied in production. 

Unsafe Condition 

(d) This AD results from a new load duty 

cycle defined by the manufacturer. 

Additional fatigue tests and calculations 

done on this basis indicated that the spoiler 

valve manifold of the S4-type spoiler servo 

controls (SSCs), and, on certain airplanes, the 

maintenance cover of the MZ–SSCs, may 

crack during its service life due to pressure 

impulse fatigue. We are issuing this AD to 

prevent fatigue cracking of certain SSCs, 

which could result in hydraulic leakage and 

consequent loss of SSC function and loss of 

the associated hydraulic system. These 

conditions could affect all three hydraulic 

systems, which could result in reduced 

controllability of the airplane. 

Compliance 

(e) You are responsible for having the 

actions required by this AD performed within 

the compliance times specified, unless the 

actions have already been done. 

Determine the Part Number of the SSCs/ 

Replace If Necessary 

(f) For Model A330–200 airplanes: Within 

70 days after the effective date of this AD, 

inspect to determine the part number of all 

SSCs in accordance with the 

Accomplishment Instructions of Airbus

exceed the total flight cycles specified in 

paragraph (f)(2)(i) or (f)(2)(ii) of this AD, as 

applicable, or if the total flight cycles are

On June 19, 2006, a final rule was 

published in the Federal Register,
