AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

We propose to supersede Airworthiness Directive (AD) 2013-13-16, which applies to all Airbus Model A330-200, A330-200 Freighter, A330-300 series airplanes, and all Airbus Model A340-200, -300, -500, and -600 series airplanes. AD 2013-13-16 currently requires repetitive inspections for discrepancies of the ball-screw assembly of the trimmable horizontal stabilizer actuator (THSA), 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, Start Printed Page 91883which ends certain repetitive inspections. Since we issued AD 2013-13-16, we have determined that a modification that automatically detects failure of the ball-screw assembly is necessary. This proposed AD would require an inspection, corrective actions if necessary, lubrication of the ball-nut, modification of the THSA, and removal of certain airplanes from the applicability. We are proposing this AD to address the unsafe condition on these products.

DATES:

We must receive comments on this proposed AD by February 2, 2017.

Discussion

On June 21, 2013, we issued AD 2013-13-16, Amendment 39-17504 (78 FR 47537, August 6, 2013) (“AD 2013-13-16”). AD 2013-13-16 requires actions intended to address an unsafe condition on all Airbus Model A330-200, A330-200 Freighter, and A330-300 series airplanes, and all Airbus Model A340-200, -300, -500, and -600 series airplanes.

Since we issued AD 2013-13-16, Airbus transferred most of the requirements of AD 2013-13-16 into airworthiness limitations, except the requirements for ECAM fault messages.

The European Aviation Safety Agency (EASA) which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2014-0219, dated September 29, 2014 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition on all Airbus Model A330 and Model A340 series airplanes. 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. Investigation results showed that this was caused by water ingress into the ball-nut, resulting in the jamming of the ball transfer circuit when the water froze. If the three (independent) ball circuits fail, then the THSA operates on a fail-safe nut (which operates without balls), which jams after several movements on the ball-screw of the THSA.

This condition, if not detected and corrected, could damage the ball-screw and the fail-safe nut, possibly resulting in jamming of the THSA and consequent reduced control of the aeroplane.

To detect at an early stage any distortion or initiation of disconnection, [Directorate General for Civil Aviation] DGAC France issued AD 2001-356 and AD 2001-357 to require repetitive inspections of the transfer tubes and their collars and, depending on findings, corrective action(s).

Prompted by another case of transfer tube disconnection, DGAC France issued AD 2001-356R2 and AD 2001-357R2 to require additional repetitive greasing and reinforcement of the ball-nut maintenance greasing instructions.

Subsequently, DGAC France issued AD 2002-037 and AD 2002-038 to require a modification that was also terminating action for the repetitive inspections and greasing tasks required by DGAC France AD 2001-356R2 and AD 2001-357R2 for the THSA P/N 47172 by application of Service Bulletin (SB) A330-27-3085 or SB A340-27-4089 (equivalent to Airbus production modification 49590), as applicable, changing the THSA P/N from 47172 to 47172-300.

Later on, DGAC France issued AD 2002-414 (later revised to R3) and AD 2002-415 (later revised to R2), which superseded the DGAC France AD 2001-356R2, AD 2001-357R2, AD 2002-037, and AD 2002-038, requiring:

—Repetitive inspections of all THSA P/N in service,

—repetitive lubrication of some THSA P/N, and

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

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 [electronic centralized aircraft monitor] ECAM. For that reason, DGAC France AD 2002-414 and AD 2002-415 also required inspection of the THSA after display of such message(s).

After those [DGAC France] ADs were issued, Airbus introduced 4 new THSA, P/N 47172-500, P/N 47172-510, P/N 47172-520 and P/N 47172-530.

As these new THSA also needed to be inspected/lubricated, EASA issued [EASA] AD 2010-0192 and [EASA] AD 2010-0193, which retained the requirements of DGAC France AD F-2002-414R3 and AD F-2002-415R2 respectively, which were superseded, to add required repetitive inspections and lubrications of the new THSA P/N.

Since those [EASA] ADs were issued, all requirements of EASA AD 2010-0192 and AD 2010-0193 were transferred into Airbus Airworthiness Limitations Section (ALS) Part 4, except the requirement of paragraph (2.3) of those [EASA] ADs. At this time, compliance with ALS Part 4 tasks is required by EASA AD 2013-0268 (A330 aeroplanes) and [EASA] AD 2013-0269 (A340 aeroplanes), respectively [which correspond to FAA AD 2015-16-02, Amendment 39-18227 (80 FR 48019, August 11, 2015); and AD 2014-23-17, Amendment 39-18033 (79 FR 71304, December 2, 2014) (A340 airplanes); respectively.]Start Printed Page 91884

In addition, Airbus developed a Checkable Shear Pin (CSP) for the THSA and an associated additional electrical harness, which consists of installation of two Electrical Detection Devices (EDD) on the lower attachment secondary load path, which gives an indication to the Flight Control Primary Computers of secondary load path engagement.

After embodiment of these modifications on an aeroplane, the repetitive inspections of the ball-screw assembly for integrity of the primary and secondary load paths is no longer required, because the failure is detected automatically by this new device.

For the reasons described above, this [EASA] AD retains only the requirement of paragraph (2.3) of EASA AD 2010-0192 and 2010-0193 [actions following ECAM fault messages], which are superseded, and requires the installation of CSP and associated additional electrical harness on the THSA of the aeroplane. This [EASA] AD also requires, for A340-500/-600 aeroplanes that are post-SB A340-92-5008 (at Revision 06 or earlier), accomplishment of A340 ALS Part 3 task 274000-B0002-1-C, providing a grace period of 3 months for aeroplanes that have exceeded the applicable threshold or interval.

The unsafe condition is the degraded operation of the THSA, which could result in reduced control of the airplane.

Model A330-223F and A330-243F airplanes have been removed from the applicability of this proposed AD to correspond with the MCAI.

Required actions include a detailed inspection and corrective actions if an ECAM fault message is displayed, repetitive lubrication of the THSA ball-nut, and a modification of the THSA by installing a CSP and associated electrical harness.

Required actions also include certain “Additional Work” that is described in the following service information.

  • “Additional Work” in Airbus Service Bulletin A330-27-3143, Revision 01, dated July 10, 2012, is described as removing the closing plug from the electrical harness 4515VB and connecting the electrical harness 4515VB to the THSA.
  • “Additional Work” in Airbus Service Bulletin A330-92-3046, Revision 06, dated November 15, 2013; and Airbus Service Bulletin A340-92-4056, Revision 04, dated December 5, 2013; is described as replacement of a certain harness item, installation of placards and cable support, modification of a certain bracket, and installation of a certain spacer.
  • “Additional Work” in Airbus Service Bulletin A340-92-5008, Revision 07, dated February 8, 2013, is described as replacing a certain wiring harness, replacing a certain THSA harness, installing additional placards, and modifying a certain wire harness installation order.

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.

Explanation of Proposed Compliance Times

The MCAI requires operators to modify certain airplanes by installing a CSP by a certain date. In order to provide operators with sufficient time to accomplish the modification, we have determined that a 12-month period from the effective date of this AD is acceptable. This difference had been coordinated with the EASA.Start Printed Page 91885

Costs of Compliance

We estimate that this proposed AD affects 33 airplanes of U.S. registry.

The actions required by AD 2013-13-16, and retained in this proposed AD take about 1 work-hour per product, at an average labor rate of $85 per work-hour. Based on these figures, the estimated cost of the actions that are required by AD 2013-13-16 is $85 per product.

We also estimate that it would take about 67 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 $14,198 per product. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $656,469, or $19,893 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 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.
