Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede an existing airworthiness directive 
(AD) that applies to all Airbus Model A330-200 and -300 series 
airplanes, and Model A340-200 and -300 series airplanes. The existing 
AD currently requires a repetitive inspection program on certain check 
valves in the hydraulic systems that includes, among other things, 
inspections for lock wire presence and integrity, traces of seepage or 
black deposits, proper torque, alignment of the check valve and 
manifold, installing new lock wire, and corrective actions if needed. 
Since we issued that AD, additional in-service reports of check valves 
loosening at lower flight cycle thresholds than previously reported 
have been received. This proposed AD would expand the applicability, 
reduce the compliance

time, change torque values of the check valve tightening, and require a 
repetitive inspection program for certain check valves in the hydraulic 
systems on airplanes that have had a certain modification embodied 
during production or in-service. We are proposing this AD to detect and 
correct such check valve loosening, which could result in hydraulic 
leaks, possibly leading to the loss of all three hydraulic systems and 
consequent loss of control of the airplane.

Discussion

    On November 16, 2009, we issued AD 2009-24-09, Amendment 39-16068 
(74 FR 62208, November 27, 2009). That AD required actions intended to 
address an unsafe condition on Airbus Model A330-200 and -300 series 
airplanes, and Model A340-200 and -300 series airplanes.
    Since we issued AD 2009-24-09, Amendment 39-16068 (74 FR 62208, 
November 27, 2009), the European Aviation Safety Agency (EASA), which 
is the Technical Agent for the Member States of the European Community, 
has issued EASA Airworthiness Directive 2012-0244R1, dated January 25, 
2013 (referred to after this as ``the MCAI''), to correct an unsafe 
condition for the specified products. The MCAI states:

    An A330 operator experienced a yellow hydraulic circuit low 
level due to a loose check valve, Part Number (P/N) CAR401. During 
the inspection on the other two hydraulic systems, the other three 
check valves P/N CAR401 were also found to be loose with their lock 
wire broken in two instances. Airbus A340 aeroplanes are also 
equipped with P/N CAR401 high pressure manifold check valves.
    Additional cases of P/N CAR401 check valve loosening have been 
reported on aeroplanes having accumulated more than 1,000 [total] 
flight cycles (FC). The check valve fitted on the Yellow hydraulic 
system is more affected, due to additional system cycles induced by 
cargo door operation.
    This condition, if not detected and corrected, could result in 
hydraulic leaks, possibly leading to the loss of all three hydraulic 
systems and consequent loss of control of the aeroplane.
    To address this unsafe condition, EASA issued Emergency AD 2009-
0223-E [which corresponds to FAA AD 2009-24-09, Amendment 39-16068 
(74 FR 62208, November 27, 2009)] to require an inspection programme 
to detect any check valve loosening and if necessary, to apply the 
applicable corrective actions.
    EASA AD 2010-0145, which superseded EASA EAD 2009-0223-E 
retaining its requirements, was issued to expand the applicability 
to the newly certified models A330-223F and A330-243F.
    Prompted by further reported in-service events of check valve P/
N CAR401 loosening before reaching the threshold of 700 FC, EASA AD 
2011-0139, which superseded EASA AD 2010-0145, retaining its 
requirements, was issued to:

--extend the requirement to identify the P/N CAR401 check valves to 
all aeroplanes, and to
--reduce the inspection threshold for aeroplanes fitted with check 
valve P/N CAR401, either installed in production through Airbus 
modification 54491, or installed in service through Airbus Service 
Bulletin (SB) A330-29-3101 or Airbus SB A340-29-4078.

    EASA AD 2012-0070, which superseded EASA AD 2011-0139, retaining 
its requirements, was issued to require an increased torque value of 
the check valve tightening and High Pressure (HP) manifold re-
identification.
    Since EASA AD 2012-0070 was issued, additional in-service events 
have been reported on aeroplanes fitted with check valves on which 
the increased torque value had been applied. Based on those events, 
it has been concluded that the action to re-torque the check valves 
with an increased value is not a satisfactory terminating action for 
addressing the issue of those check valves.
    For the reasons described above, this new [EASA] AD partially 
retains the requirements of EASA AD 2012-0070, which is superseded. 
Additionally, for aeroplanes equipped with P/N CAR401 on which the 
increased torque value has been applied, this new [EASA] AD requires 
repetitive inspections of the check valves and HP manifolds. 
Finally, this [EASA] AD also requires application of a lower torque 
value when a check valve P/N CAR401 is installed on an aeroplane.
    This [EASA] AD is considered to be an interim action and further 
AD action may follow.
    Note: the reporting and the torque value increase requirements 
for check valves P/N CAR401 of EASA AD 2012-0070 are no longer part 
of this new [EASA] AD.

This proposed AD would expand the applicability to include Model A330-
200 freighter series airplanes, reduce the compliance time for initial 
inspection, and change torque values of the check valve tightening. The 
corrective actions include replacing seal assemblies, re-torquing the 
check valve, and replacing the lock wire.
    You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Airbus has issued the following service information.
     Airbus Alert Operators Transmission A29L001-12, dated 
October 11, 2012.
     Airbus Mandatory Service Bulletin A330-29-3111, Revision 
02, dated June 23, 2011.
     Airbus Mandatory Service Bulletin A340-29-4086, Revision 
02, dated June 23, 2011.

The actions described in this service information are intended to 
correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 67 products of U.S. registry.
    The actions that are required by AD 2009-24-09, Amendment 39-16068 
(74 FR 62208, November 27, 2009), and retained in this proposed AD take 
about 8 work-hours per product, at an average labor rate of $85 per 
work hour. Based on these figures, the estimated cost of the currently 
required actions is $680 per product.
    We estimate that it would take about 2 work-hours per product to 
comply with the new basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Based on these figures, we estimate 
the cost of the proposed AD on U.S. operators to be $11,390, or $170 
per product.
    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this proposed 
AD.

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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    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 proposed AD and placed it in the AD docket.
