Airworthiness Directives; Airbus Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Proposed rule; withdrawal.
-----------------------------------------------------------------------
SUMMARY: The FAA withdraws a notice of proposed rulemaking (NPRM) that
proposed a new airworthiness directive (AD) for all Airbus Model A330
series airplanes. The NPRM would have required replacement of the
elevator servo-controls with new servo-controls when the existing parts
have reached their operational life limit. Since the NPRM was issued,
we have determined that more restrictive maintenance requirements and
airworthiness limitations are necessary and that NPRM does not
adequately address the identified unsafe condition. Accordingly, the
NRPM is withdrawn.
DATES: As of November 20, 2013, the proposed rule, which was published
in the Federal Register on September 18, 2003, (68 FR 54694), is
withdrawn.
ADDRESSES: You may examine the AD docket on the Internet at http://www.regulations.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 this AD action, the NPRM (68 FR 54694,
September 18, 2003), the Mandatory Continuing Airworthiness Information
(MCAI), the regulatory evaluation, any comments received, and other
information. The address for the Docket Office (phone: 800-647-5527) is

SUPPLEMENTARY INFORMATION:
Discussion
We proposed to amend part 39 of the Federal Aviation Regulations
(14 CFR part 39) with a notice of proposed rulemaking (NPRM) for a new
AD for all Airbus Model A330 series airplanes. The NPRM, FAA Docket No.
FAA-2013-0972, Directorate Identifier 2002-NM-009-AD identified as the
``Directorate Identifier'' in this AD action), was published in the
Federal Register on September 18, 2003 (68 FR 54694). The NPRM proposed
to correct an unsafe condition for the specified products.
[[Page 69595]]
The Direction G[eacute]n[eacute]rale de l'Aviation Civile (DGAC),
which is the aviation authority for France, issued French Airworthiness
Directive 2001-545(B) R1, dated October 16, 2002 (referred to after
this as ``the MCAI''), to correct an unsafe condition for the specified
products. The MCAI states:
The operational life limits of the aircraft servo-controls, and
in particular of the elevator servo-controls given in the Revision 8
of AMM Chapter 05-11-00 Configuration 1 (dated September 15, 1999)
are not addressed by the definition of the structural life limits of
Safe Life items as defined in Section 9.1 (Life limits/Monitored
parts) of the Airworthiness Limitations Section (located in the MPD
Section 9) which replaces the aircraft AMM Chapter 05-11. As a
result these life limits are removed from the above documents and
integrated into this [French] Airworthiness Directive (AD).
In addition, this [French] AD restates the life limits
requirements of AD 95-032-008(B) R1, and introduces provisional
operational life limits for P/N's SC-4800-7A and SC-4800-9.
The aim of this [French] AD is to require the removal and
replacement of the servo-controls when they have reached their
operational life limits.
The Revision 1 of this [French] AD aims to increase the
operational life limit in active mode of Elevator Servo-controls P/N
SC4800 listed in paragraph COMPLIANCE 3.2.3. of this [French] AD,
following new test results demonstrating a provisional life of
40,000 cycles and to remove reference of P/N SC4800-2 amendments A,
B, C, D, E, F or G and SC4800-4 amendment H which are not anymore in
service under this identification.
The NPRM (68 FR 54694, September 18, 2003) resulted from reports of
cracking in the end caps and along the barrel on elevator servo-
controls that exceeded their operational life limits, which could lead
to hydraulic leakage and internal damage within the servo-control. The
proposed actions were intended to prevent hydraulic leakage and
internal damage of the elevator servo-controls due to cracks in the end
caps and along the barrel, which could result in a reduction in the
elevator's protection against vibration or loss of the hydraulic
circuit, and consequent reduced controllability of the airplane. You
may obtain further information by examining the MCAI in the AD docket.
Actions Since NPRM (68 FR 54694, September 18, 2003) Was Issued
Since we issued the NPRM (68 FR 54694, September 18, 2003), we have
determined that more restrictive maintenance requirements and
airworthiness limitations are necessary to adequately address the
identified unsafe condition. French Airworthiness Directive 2001-545(B)
R1, dated October 16, 2002, was superseded by The European Aviation
Safety Agency (EASA) Airworthiness Directive 2012-0020, dated January
30, 2012, which mandates the use of Airbus A330 Airworthiness
Limitations Section (ALS) Part 4--Aging Systems Maintenance, Revision
03, dated September 9, 2011. The replacement requirements and
thresholds for parts originally defined in the NPRM are now contained
in Airbus A330 ALS Part 4--Aging Systems Maintenance, Revision 03,
dated September 9, 2011. We have issued NPRM Docket No. FAA-2013-0834,
Directorate Identifier 2012-NM-045-AD (78 FR 66861, November 7, 2013),
which corresponds to EASA Airworthiness Directive 2012-0020, dated
January 30, 2012. The NPRM, FAA Docket No. FAA-2013-0834, Directorate
Identifier 2012-NM-045-AD, applies to certain Airbus Model A330 and
A340 series airplanes and proposes to mandate the requirements now
contained in Airbus A330 ALS Part 4--Aging Systems Maintenance,
Revision 03, dated September 9, 2011.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (68 FR 54694, September
18, 2003) or on the determination of the cost to the public.
FAA's Conclusions
Upon further consideration, we have determined that more
restrictive maintenance requirements and airworthiness limitations are
necessary to adequately address the unsafe condition identified in the
NPRM (68 FR 54694, September 18, 2003), and that additional rulemaking
is necessary. Accordingly, the NPRM is withdrawn.
Withdrawal of the NPRM (68 FR 54694, September 18, 2003) does not
preclude the FAA from issuing another related action or commit the FAA
to any course of action in the future.
Regulatory Impact
Since this action only withdraws an NPRM (68 FR 54694, September
18, 2003), it is neither a proposed nor a final rule and therefore is
not covered under Executive Order 12866, the Regulatory Flexibility
Act, or DOT Regulatory Policies and Procedures (44 FR 11034, February
26, 1979).

Register on September 18, 2003 (68 FR 54694).
