Start Preamble

AGENCY:

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

ACTION:

Final rule.

SUMMARY:

We are superseding airworthiness directive (AD) 2005-07-04 for all Airbus Model A330-200 and -300 series airplanes, and Model A340-200 and -300 series airplanes. AD 2005-07-04 required repetitive inspections to detect discrepancies of the transfer tubes and the collar of the ball nut of the trimmable horizontal stabilizer actuator (THSA), and corrective action if necessary; repetitive inspections for discrepancies of the ball screw assembly, and corrective action if necessary; repetitive greasing of the THSA ball nut, and replacement of the THSA if necessary; and modification or replacement (as applicable) of the ball nut assembly, which ends certain repetitive inspections. This new AD removes certain inspections, revises certain actions, and adds airplanes to the applicability. This AD was prompted by several reports of Start Printed Page 47538disconnection of the transfer tube from the ball nut of the THSA. We are issuing this AD to prevent degraded operation of the THSA, which could result in reduced controllability of the airplane.

DATES:

This AD becomes effective September 10, 2013.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of September 10, 2013.

The Director of the Federal Register approved the incorporation by reference of certain other publications listed in this AD as of May 4, 2005 (70 FR 16104, March 30, 2005).

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. The NPRM was published in the Federal Register on October 2, 2012 (77 FR 60075), and proposed to supersede AD 2005-07-04, Amendment 39-14028 (70 FR 16104, March 30, 2005). (AD 2005-07-04 superseded AD 2001-11-09, Amendment 39-12252 (66 FR 31143, June 11, 2001).) The NPRM proposed to correct an unsafe condition for the specified products. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2010-0192 (corrected), dated October 11, 2010; and EASA Airworthiness Directive 2010-0193 (corrected), dated October 11, 2010; (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states:

Several cases of transfer tube disconnection from the ball-nut of the trimmable horizontal stabilizer actuator (THSA) part number (P/N) 47172 and 47147-400 were detected on the ground during greasing and maintenance.

This condition is caused by water ingress into the ball-nut resulting in the jamming of the ball transfer circuit when the water freezes.

If the three (independent) ball circuits fail, then the THSA will operate on a fail-safe nut. This nut (which operates without balls) would then jam after several movements on the screw of the THSA.

This degraded operation is not detectable in the cockpit by the crew as long as the THSA does not jam and could damage the ball screw and the fail-safe nut.

To detect this unsafe condition, [Dirección General de Aviación Civil] DGAC France AD F-2001-356 [and F-2001-357] was issued to require repetitive inspections of the transfer tubes and their collars in order to detect at an early stage any distortion or initiation of disconnection.

Further to a new case of transfer tube disconnection, * * * [revised DGAC ADs] required an additional repetitive greasing task with reinforcement of the ball-nut maintenance greasing instructions.

In addition, the electrical flight control computers monitor the operation of the THSA and the jamming of this actuator could be detected and indicated by messages on the maintenance system and on the ECAM [electronic centralized aircraft monitor]. In this case a mandatory inspection of the THSA is required before the next flight.

DGAC France AD F-2002-038 [and F-2002-037] required application of a final fix (related to inspection and greasing task required by DGAC France AD F-2001-356 [and F-2001-357]) for the THSA P/N 47172 by application of Airbus modification 49590/Service Bulletin (SB) A330-27-3085 [or SB A340-27-4089]. It changes the THSA P/N from 47172 to 47172-300.

Later on, DGAC France AD F-2002-414R3 replaced the DGAC AD France F-2001-356R2 and F-2002-038 [and DGAC France AD F2002-415R2 superseded DGAC France ADs F-2001-357R2 and F-2002-037] requiring:

—the repetitive [detailed] inspection [for discrepancies] of all THSA P/N in service [for integrity of the primary and secondary load path and check the Checkable Shear Pins (CSPs)], and

—the lubrication of some THSA P/N, and

—the replacement of THSA P/N 47172, 47147-400 and 47147-2XX/-3XX

[DGAC France AD F-2002-414R3 and F-2002-415R2 correspond to FAA AD 2005-07-04, Amendment 39-14028 (70 FR 16104, March 30, 2005).]

Airbus has later introduced 4 new THSA P/N (47172-500, 47172-510, 47172-520 and 47172-530).

This [EASA] AD retains the requirements of DGAC France AD F-2002-414R3 [and F-2002-415R2], which is superseded, and requires repetitive inspections and lubrications of the new THSA P/N.

The repetitive inspection and lubrication requirements for THSA P/N 47172-520 and 47172-530 shall [also] be included in the next Airworthiness Limitation Section (ALS) Part 4 revision.

* * * * *

Corrective actions include replacing the THSA with a new THSA if cracks, dents, or corrosion are found, or if the feeler gage has failed at any of the four gaps. Other corrective action includes using a method approved by the FAA or the EASA (or its delegated agent) for a finding of metallic debris, loose nut, damaged or missing lock washers, pins and parts, or incorrect installation of items. AD 2005-07-04, Amendment 39-14028 (70 FR 16104, March 30, 2005), required repetitive inspections for discrepancies. This AD requires, for certain airplanes, repetitive inspections for the integrity of the primary and secondary load path, and the CSPs. The unsafe condition is the degraded operation of the THSA, which could result in reduced controllability of the airplane. 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 To Use Later Document Revision

Delta Airlines (Delta) requested that paragraph (j)(2) of the NPRM (77 FR 60075, October 2, 2012) refer to Airbus A330 Airworthiness Limitations Section (ALS) Part 4—Ageing Systems Maintenance, Revision 03, dated September 9, 2011; instead of Revision 02, dated December 16, 2009. Delta stated that Revision 03 of that ALS specifies the 1,000 flight-hour lubrication threshold and repetitive interval that are specified in paragraph (j)(2) of the NPRM, whereas Revision 02 of this ALS specifies 700 flight hours for the lubrication threshold and repetitive interval.

We agree that Airbus A330 Airworthiness Limitations Section (ALS) Part 4—Ageing Systems Maintenance, Revision 03, dated September 9, 2011, correctly specifies the lubrication threshold and repetitive interval. We have changed paragraph (j)(2) of this AD accordingly. In addition, we have changed paragraph (j)(2) of this AD to reference Airbus A340 ALS Part 4—Ageing Systems Maintenance, Revision 02, dated October 12, 2011; and Revision 03, dated November 15, 2012; for the same reason.

Request To Change Wording

Delta requested that we change the wording in paragraph (l) of the NPRM (77 FR 60075, October 2, 2012), which states “For airplanes identified in paragraph (k) of this AD.” The commenter asked that the wording “identified in” be replaced with Start Printed Page 47539“affected by.” The commenter provided no reason for the change.

We disagree to change the wording in paragraph (n) in this AD (identified as paragraph (l) in the NPRM (77 FR 60075, October 2, 2012)) as requested by the commenter. However, we have moved the content of paragraphs (k)(1), (k)(2), and (k)(3) of the NPRM to new paragraph (l) in this AD to clarify the actions and affected airplanes. We have also moved the content of paragraph (k)(6) of the NPRM to new paragraph (m) of this AD, and re-identified succeeding paragraphs accordingly. Finally, in paragraph (n) of this AD, we revised the wording to describe the affected airplanes.

Request To Include Additional Part Number

Delta requested that we include THSA P/N 47172-520 and P/N “47127-530” in paragraph (m) of the NPRM (77 FR 60075, October 2, 2012) as applicable part numbers for Model A330 series airplanes.

We disagree to include THSA P/N 47127-530 as there is no such part number. We infer that the commenter meant to specify THSA P/N 47172-530. THSA P/N 47172-520 and P/N 47172-530 are not included in the MCAI. However, all necessary tasks for those THSA part numbers are contained in Airbus A330 Airworthiness Limitations Section (ALS) Part 4—Ageing Systems Maintenance, Revision 03, dated September 9, 2011; and Airbus A340 ALS Part 4—Ageing Systems Maintenance, Revision 02, dated October 12, 2011, and Revision 03, dated November 15, 2012. The FAA NPRMs to mandate these ALS Part 4 documents are pending at this time. Therefore, we have not changed this AD in this regard.

Request To Consider Another EASA AD

Corinne Dayde stated that she “Cannot see how EASA 2012-0061 is considered.”

We are considering addressing EASA AD 2012-0061R1, dated November 30, 2012, in a separate FAA AD. We have not changed this AD in this regard.

Conclusion

We reviewed the available data, including the comments received, and determined that air safety and the public interest require adopting this 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 60075, October 2, 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 60075, October 2, 2012).

Costs of Compliance

We estimate that this AD will affect about 33 products of U.S. registry.

The actions that are required by AD 2005-07-04, Amendment 39-14028 (70 FR 16104, March 30, 2005), and retained in this AD take up to 36 work-hours per product, at an average labor rate of $85 per work-hour. Based on these figures, the estimated cost of the retained actions is up to $3,060 per product.

We estimate that it will take about 2 work-hours per product to comply with the new basic requirements of this AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this AD on U.S. operators to be $5,610, 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 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 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 this AD, 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.
