AGENCY:
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.

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
PO 00000
Frm 00025
Fmt 4700
Sfmt 4700
Date
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
E:\FR\FM\07MRR1.SGM
07MRR1
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.

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.

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.

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

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
[[Page 10058]]
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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
Adoption of the Amendment
0
Accordingly, under the authority delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The Federal Aviation Administration (FAA) amends Sec. 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
