Start Preamble

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 Start Printed Page 26717time, 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.

DATES:

We must receive comments on this proposed AD by June 24, 2013.

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.

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.
