Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Airbus Model A330-200 and A330-300 series airplanes, and Model A340-200 
and A340-300 series airplanes. This AD was prompted by reports of an 
elevator blocked in the down position due to two independent failures; 
first, the inability of a servo control to switch to active mode 
because it was not detected by a flight control computer; and second, 
an internal hydraulic leak due to the deterioration of an O-ring seal 
on a solenoid. This AD requires, depending on airplane configuration, 
modifying three flight control primary computers (FCPCs); modifying two 
flight control secondary computers (FCSCs); revising the airplane 
flight manual (AFM) to include certain information; replacing certain 
O-rings; and checking part number and replacing certain O-ring seals if 
needed. We are issuing this AD to detect and correct O-rings with 
incorrect part numbers whose deterioration could lead to improper 
sealing of solenoid valves; and to correct FCPC and FCSC software to 
allow better control of elevator positioning; both conditions, if not 
corrected, could lead to the loss of elevator control on takeoff, and 
potentially reduce the controllability of the airplane.

DATES: This AD becomes effective June 13, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of June 13, 
2013.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM was published in the Federal Register on August 14, 2012 (77 
FR 48469). That NPRM proposed to correct an unsafe condition for the 
specified products. The Mandatory Continuing Airworthiness Information 
(MCAI) states:

    This [European Aviation Safety Agency (EASA)] AD [2010-0081, 
dated April 27, 2010] deals with the two following points:
     Case of an elevator blocked in down position due to two 
independent failures one of which is hidden:
    Each elevator is controlled by two servo controls. In normal 
operation:

--one servo control in active mode controlled by PRIM 1 (Green servo 
control),
--one servo control in damping mode (Yellow or Blue servo control) 
monitored by PRIM 2.

    Change from active mode to damped mode is obtained by means of a 
mode selector which is controlled by two identical solenoid valves 
housed on the servo control. The sealing of each solenoid valve is 
ensured by four O-ring seals.
    During pre-flight control checks, the flight crew of an A330-200 
aeroplane observed that one of the elevators was blocked in down 
position, the ECAM [electronic centralized aircraft monitor] screen 
displaying ``F/CTL PRIM 1 PITCH FAULT''.
    This condition was due to two independent failures, one of which 
was dormant, which occurred on one of the elevators.
    Investigations revealed that the origin of the elevator 
malfunction was due to the inability of the Yellow servo control to 
switch to active mode.
    This inability:

--was caused by an internal hydraulic leak due to the deterioration 
of an O-ring seal on a solenoid valve,

[[Page 27016]]

--was not detected by the PRIM 2 computer nor announced to the 
flight crew.

     Incorrect Part Number (P/N) for solenoid valve O-ring 
seals in IPC [illustrated parts catalog]:
    An incorrect O-ring seal P/N in IPC 27-34-51-1 could have led to 
the installation of O-ring seals incompatible with the hydraulic 
fluid, causing them to deteriorate.
    These conditions if not detected could lead to the loss of 
elevator [control] on takeoff and, potentially reduce the 
controllability of the aeroplane.
    The aim of EASA AD 2007-0009 was to:

--take over the requirements of AD F-2004-158, and
--require the terminating action for Sec.  (1), (2) and (4) of this 
[EASA] AD by introducing new capped seals on solenoid valves for 
A330-200 only.

    This new [EASA] AD * * * requires the embodiment of the latest 
software standard on the three Flight Control Primary Computers 
(FCPC) and on the two Flight Control Secondary Computers (FCSC) [by 
modifying the FCPCs and FCSCs] * * *.

    The modification is accomplished either by replacing the FCPCs and 
FCSCs with new FCPCs and FCSCs, or by replacing or reprogramming the 
on-board replaceable modules in the FCPCs and FCSCs. Required actions 
also include, depending on airplane configuration, the following 
actions: Revising the AFM to include certain information; replacing 
certain O-rings; and checking part number and replacing certain O-ring 
seals if needed. You may obtain further information by examining the 
MCAI in the AD docket.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comments received.

Request for Exemption for Later Standards of FCPC Software

    Delta Air Lines, Inc. (Delta) requested that we revise the NPRM (77 
FR 48469, August 14, 2012) to provide an exemption for later standards 
of FCPC software. Since completing Airbus Mandatory Service Bulletin 
A330-27-3148, Revision 01, dated October 9, 2008, Delta stated that it 
upgraded FCPC software from standard P9/M18 to newer standard P11A/M20A 
as specified in Airbus Mandatory Service Bulletin A330-27-3176, dated 
July 26, 2011. Delta noted that when there are significant differences 
between the airspeed sources, the autopilot (AP) and the auto-thrust 
(A/THR) are designed to disconnect, and the flight directors (FD) bars 
are automatically removed. Delta also noted that if two of the airspeed 
sources then read similar, yet erroneous numbers, the AP and A/THR will 
re-engage, and the FD bars will reappear. Delta stated that this newer 
standard addresses these safety concerns.
    We agree to revise this AD to allow modification of the FCPC with 
the software identified in Airbus Mandatory Service Bulletin A330-27-
3176, Revision 02, dated April 24, 2012, as well as the software 
identified in Airbus Mandatory Service Bulletin A330-27-3177, dated 
December 21, 2011; Airbus Mandatory Service Bulletin A340-27-4174, 
dated November 21, 2011; and Airbus Mandatory Service Bulletin A340-27-
4162, Revision 01, dated September 17, 2012. We have added paragraph 
(o) to this AD to specify that modification of the three FCPC with new 
software specified in paragraphs (o)(1) through (o)(4) of this AD is 
acceptable for compliance with the requirements of paragraph (l) of 
this AD.
    In addition, we have added new paragraph (p)(4) of this AD to give 
credit for performing actions before the effective date of this AD 
using Airbus Service Bulletin A330-27-3176, dated July 26, 2011; Airbus 
Mandatory Service Bulletin A330-27-3176, Revision 01, dated March 27, 
2012; and Airbus Mandatory Service Bulletin A340-27-4162, dated January 
10, 2012.
    We are also considering further rulemaking that would correspond to 
EASA AD 2011-0199R1, dated February 17, 2012, to mandate implementation 
of these new FCPC standards.

Request for Credit for Modification of FCPC Software Using Airbus 
Mandatory Service Bulletin A330-27-3148, Revision 01, October 9, 2008

    Delta requested that we revise paragraph (o)(2) of the NPRM (77 FR 
48469, August 14, 2012) to give credit for modification of FCPC 
software done using Airbus Mandatory Service Bulletin A330-27-3148, 
Revision 01, dated October 9, 2008. This service bulletin is the 
appropriate source of service information for accomplishing the actions 
required by paragraph (l) of the NPRM. Delta stated that paragraph 
(o)(2) of the NPRM provides credit, if those actions were performed 
using Airbus Service Bulletin A330-27-3144, dated April 2, 2009, but 
there are no statements giving credit for modifications of the FCPC 
performed using Airbus Mandatory Service Bulletin A330-27-3148, 
Revision 01, dated October 9, 2008.
    We disagree with this request to revise this AD, but agree to 
clarify that this AD allows for previous accomplishment of the 
modification using Airbus Mandatory Service Bulletin A330-27-3148, 
Revision 01, dated October 9, 2008. Paragraph (l) of this AD mandates 
modifications of FCPC software using current revisions of the service 
information, Airbus Service Bulletin A330-27-3144, Revision 01, dated 
July 16, 2009; or Airbus Mandatory Service Bulletin A330-27-3148, 
Revision 01, October 9, 2008. Paragraph (p)(2) of this AD (referred to 
as paragraph (o)(2) in the NPRM (77 FR 48469, August 14, 2012)) gives 
credit only for actions performed using previous revisions of the 
service information specified in paragraph (l) of this AD, i.e., Airbus 
Mandatory Service Bulletin A330-27-3144, dated April 2, 2009; and 
Airbus Mandatory Service Bulletin A330-27-3148, dated July 17, 2008. 
Since paragraph (f) of this AD indicates previous accomplishment of 
modifications do not need to be repeated, the intent of the comment is 
addressed. No change has been made to the AD in this regard.

Request for Credit for Modification of FCSC Software Using Airbus 
Service Bulletin A330-27-3145, Revision 1, Dated July 17, 2008

    Delta requested that we revise paragraph (o)(3) of the NPRM (77 FR 
48469, August 14, 2012) to give credit for modification of the FCSC 
software done using Airbus Mandatory Service Bulletin A330-27-3146, 
Revision 01, dated September 3, 2008; and Airbus Service Bulletin A330-
27-3145, dated December 16, 2008. Delta noted these service bulletins 
are referred to as the appropriate sources of service information for 
accomplishing the actions proposed by paragraph (m) of the NPRM. Delta 
stated that paragraph (o)(3) of the NPRM provides credit, if those 
actions were performed using Airbus Mandatory Service Bulletin A330-27-
3146, dated June 1, 2007, but pointed out that there are no statements 
giving credit for modifications of the FCSC performed using Airbus 
Mandatory Service Bulletin A330-27-3146, Revision 01, dated September 
3, 2008.
    We disagree with this request to revise this AD but agree to 
clarify that this AD allows for previous accomplishment of the 
modification using Airbus Mandatory Service Bulletin A330-27-3146, 
Revision 01, dated September 3, 2008; and Airbus Service Bulletin A330-
27-3145, dated December 16, 2008. Paragraph (m) of this AD mandates 
modifications of FCSC software using Airbus Mandatory Service Bulletin 
A330-27-3146, Revision 01, dated September 3, 2008; or Airbus Service 
Bulletin A330-27-3145, dated December 16, 2008. Paragraph (p)(3) of 
this AD (referred to as paragraph (o)(3) in the NPRM (77 FR 48469, 
August 14, 2012)) gives credit

[[Page 27017]]

only for actions performed using previous revisions of the service 
information specified in paragraph (m) of this AD, i.e., Airbus Service 
Bulletin A330-27-3146, dated June 1, 2007. Since paragraph (f) of this 
AD indicates previous accomplishment of modifications do not need to be 
repeated, the intent of the comment is addressed. No change has been 
made to the AD in this regard.

Request for Credit for Installation of Modified Servo-Controls Using 
Airbus Service Bulletin A330-27-3134, Revision 01, Dated May 12, 2006; 
and Airbus Mandatory Service Bulletin A330-27-3136, Revision 1, Dated 
July 19, 2006

    Delta requested that we revise paragraph (p) of the NPRM (77 FR 
48469, August 14, 2012) to give credit for the installation of modified 
servo-controls done using Airbus Service Bulletin A330-27-3134, 
Revision 01, dated May 12, 2006; and Airbus Mandatory Service Bulletin 
A330-27-3136, Revision 01, dated July 19, 2006.
    We disagree with this request to revise this AD, but agree to 
clarify that this AD allows for previous accomplishment of the 
installation using Airbus Service Bulletin A330-27-3134, Revision 01, 
dated May 12, 2006; and Airbus Mandatory Service Bulletin A330-27-3136, 
Revision 01, dated July 19, 2006. Paragraph (q) of this AD (referred to 
as paragraph (p) of the NPRM (77 FR 48469, August 14, 2012)) provides 
terminating action for the actions required by paragraphs (g), (h), and 
(i) of this AD, if the installation of modified servo-controls was 
using Airbus Service Bulletin A330-27-3134, Revision 01, dated May 12, 
2006; and Airbus Mandatory Service Bulletin A330-27-3136, Revision 01, 
dated July 19, 2006. Since paragraph (f) of this AD indicates previous 
accomplishment of the installation not need to be repeated, the intent 
of the comment is addressed. No change has been made to the AD in this 
regard.

Explanation of Change Made to This AD

    We have revised paragraph (n) of this AD to put the AFM text into 
Figure 1 to paragraph (n) of this AD, and included reference to the 
figure in that paragraph. This change does not affect the intent of 
that paragraph.

Conclusion

    We reviewed the available data, including the comments received, 
and determined that air safety and the public interest require adopting 
the AD with the changes described previously--and minor editorial 
changes. We have determined that these changes:
     Are consistent with the intent that was proposed in the 
NPRM (77 FR 48469, August 14, 2012) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (77 FR 48469, August 14, 2012).

Costs of Compliance

    We estimate that this AD will affect 41 products of U.S. registry. 
We also estimate that it will take about 5 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Required parts will cost about $0 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 parts. 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 this AD to the U.S. operators 
to be $17,425, or $425 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 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 the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979);
    3. Will not affect intrastate aviation in Alaska; and
    4. 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.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Operations office 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The AD docket contains the NPRM (77 FR 48469, August 14, 
2012), the regulatory evaluation, any comments received, and other 
information. The street address for the Docket Operations office 
(telephone (800) 647-5527) is in the ADDRESSES section. Comments will 
be available in the AD docket shortly after receipt.

(MSN).
    (2) Model A340-211, -212, -213, -311, -312, and -313 airplanes, 
all MSN.

(d) Subject

    Air Transport Association (ATA) of America Code 27: Flight 
controls.

(e) Reason

    This AD was prompted by reports of an elevator blocked in the 
down position due to two independent failures; first, the inability 
of a servo control to switch to active mode because it was not 
detected by a flight control computer; and second, an internal 
hydraulic leak due to the deterioration of an O-ring seal on a 
solenoid. We are issuing this detect and correct O-rings with 
incorrect part numbers whose deterioration could lead to improper 
sealing of solenoid valves; and to correct flight control primary 
computer (FCPC) and flight control secondary computer (FCSC) 
software to allow better control of elevator positioning; both 
conditions, if not corrected, could lead to the loss of elevator 
control on takeoff, and potentially reduce the controllability of 
the airplane.

(f) Compliance

    You are responsible for having the actions required by this AD 
performed within the compliance times specified, unless the actions 
have already been done.

(g) Replacement of O-ring Seals for Elevator Servo Controls Installed 
in Damping Position on Model A330-200 Series Airplanes Only
