AD 2012-06-07

We are superseding an existing airworthiness directive (AD) for certain Model A330-200 and -300 series airplanes, and Model A340- 200, -300, -500, and -600 series airplanes. This AD was prompted by reports of loose pneumatic quick-disconnect unions on Goodrich pitot probes that might be the result of mis-torque of the affected unions at equipment manufacturing level. This AD adds airplanes to the AD applicability. We are issuing this AD to detect and correct loose unions on the pitot probes, which could lead to an air leak, resulting in incorrect total pressure measurement and consequent erroneous calibrated airspeed (CAS)/MACH parameters delivered to the flightcrew by the air data computer.

Final rule; request for comments.

Adoption of the Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:

[[Page 16663]]

Discussion

On July 30, 2010, we issued AD 2010-17-02, Amendment 39-16392 (75 FR 50871, August 18, 2010). That AD required actions intended to address an unsafe condition on certain Model A330-200 and -300 series airplanes, and Model A340-200, -300, -500, and -600 series airplanes.
Since we issued AD 2010-17-02, Amendment 39-16392 (75 FR 50871, August 18, 2010), we have certified two new models: Model A330-223F and -243F airplanes. We are issuing this AD to include them in the requirements of that earlier AD. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2011-0138, dated July 20, 2011 (referred to after this as ``the MCAI''), to correct an unsafe condition for the specified products. The MCAI states:

Several reports have recently been received of loose pneumatic quick-disconnect unions on Goodrich pitot probes [part number] P/N 0851HL. These may be the result of mis-torque of the affected unions at equipment manufacturing level. Investigations are still on-going to determine the root cause(s).
This condition, if not corrected, could lead to an air leak, resulting in incorrect total pressure measurement and consequent erroneous Calibrated Airspeed (CAS)/MACH parameters delivered by the Air Data Computer (ADC).
As a precautionary measure, EASA issued Emergency AD 2009-0202 to require a torque check of the pneumatic quick-disconnect union on certain Goodrich P/N 0851HL pitot probes and corrective action, depending on findings.
EASA AD 2009-0202-E was subsequently republished to remove an erroneous reference to Appendix A from the Reason section, as no Appendix was attached to this [EASA] AD. [EASA] AD 2009-0202 was later revised to exclude pitot probes marked with a red torque check-mark from the torque-check required by paragraph (2.1) of this [EASA] AD.
This [EASA] AD retains the requirements ofEASA AD 2009-0202R1 [which corresponds to FAA AD 2010-17-02, Amendment 39-16392 (75 FR 50871, August 18, 2010)], which is superseded, and expands the Applicability to include the newly certified Model A330-223F and Model A330-243F aeroplanes.

Loss or fluctuation of indicated airspeed could result in misleading information provided to the flightcrew. If the quick-disconnect union fitted on the pitot probe is not adequately torqued, the corrective action includes applying torque. You may obtain further information by examining the MCAI in the AD docket.

Change to AD 2010-17-02, Amendment 39-16392 (75 FR 50871, August 18, 2010)

We have revised certain headers throughout this AD. We have also revised the wording in paragraph (g)(3) of this AD. This revision does not change the intent of paragraph (g)(3) of AD 2010-17-02, Amendment 39-16392 (75 FR 50871, August 18, 2010).

FAA's Determination and Requirements of This 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 issuing this AD because we evaluated all pertinent information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design.
There are no products of this type currently registered in the United States. However, this rule is necessary to ensure that the described unsafe condition is addressed if any of these products are placed on the U.S. Register in the future.

FAA's Determination of the Effective Date

Since there are currently no domestic operators of this product, notice and opportunity for public comment before issuing this AD are unnecessary.

Comments Invited

This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include ``Docket No. FAA-2012-0273; Directorate Identifier 2011-NM-149-AD'' at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those comments.
We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this 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 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 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 proposed AD and placed it in the AD docket.
