Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
Airbus Model A330-200 and A330-300 series airplanes, and Model A340-200 
and A340-300 series airplanes. This proposed 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 proposed AD would require, 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 proposing this AD to 
detect and correct O-rings with incorrect part number 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: We must receive comments on this proposed AD by September 28, 
2012.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2010-0081, dated April 27, 2010 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:
    This [EASA] AD 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 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,
--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 
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 airplane flight manual (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.

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.

[[Page 48471]]

Differences Between This AD and the MCAI or Service Information

    EASA AD 2010-0081, dated April 27, 2010, contains additional 
requirements to modify the four elevator servo controls installed on 
Model A330-200 series airplanes, as specified in Airbus Service 
Bulletin A330-27-3134. This AD does not contain those requirements 
because those actions are already mandated by FAA AD 2008-06-07, 
Amendment 39-15419 (73 FR 13103, March 12, 2008; as corrected on April 
15, 2008 (73 FR 20367), and must be accomplished within 17 months after 
April 16, 2008 (the effective date of AD 2008-06-07, Amendment 39-
15419). EASA AD 2010-0081, dated April 27, 2010, also contains 
additional requirements to amend the airplane flight manual to include 
the operational procedure specified in paragraph (n) of this proposed 
AD. This proposed AD does not include that requirement, because that 
information is already contained in the U.S. operators' AFMs.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 41 products of U.S. registry. We also estimate that 
it would take about 5 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $85 per 
work-hour. Required parts would 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 costs. 
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 the proposed AD on 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 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 that 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.
