2016-15929. Airworthiness Directives; Airbus Airplanes

AGENCY:

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

ACTION:

Final rule.

SUMMARY:

We are adopting a new airworthiness directive (AD) for certain Airbus Model A330-200 Freighter series airplanes; Model A330-200 and A330-300 series airplanes; Model A340-200 and A340-300 series airplanes; Model A340-500 series airplanes; and Model A340-600 series airplanes. This AD was prompted by a report indicating that, during an operational test of a ram air turbine (RAT), the RAT did not deploy in automatic mode. This AD requires identification of the manufacturer, part number, and serial number of the RAT, and re-identification and modification of the RAT if necessary. We are issuing this AD to prevent non-deployment of the RAT, which, if preceded by a total engine flame-out, or during a total loss of normal electrical power generation, could result in reduced control of the airplane.

DATES:

This AD is effective August 16, 2016.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of August 16, 2016.

SUPPLEMENTARY INFORMATION:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Airbus Model A330-200 Freighter series airplanes; Model A330-200 and A330-300 series airplanes; Model A340-200 and A340-300 series airplanes; Model A340-500 series airplanes; and Model A340-600 series airplanes. The NPRM published in the Federal Register on March 1, 2016 (81 FR 10545) (“the NPRM”).

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2015-0008, dated January 15, 2015 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for certain Airbus Model A330-200 Freighter series airplanes; Model A330-200, and A330-300 series airplanes; Model A340-200, and A340-300 series airplanes; Model A340-500 series airplanes; and Model A340-600 series airplanes. The MCAI states:

During a scheduled Ram Air Turbine (RAT) operational test on an A330 aeroplane, the RAT did not deploy in automatic mode. The subsequent investigation conducted by the RAT manufacturer Hamilton Sundstrand (HS) and Arkwin Industries, revealed that this failure to deploy was due to an inadequate stroke margin in the manufacturing shimming procedure of the actuator deployment solenoids.

This condition, if not corrected, could possibly result in reduced control of the aeroplane, particularly if occurring following a total engine flame out, or during a total loss of normal electrical power generation.

Prompted by this unsafe condition, Airbus issued Service Bulletin (SB) A330-29-3126, SB A340-29-4097 and SB A340-29-5025, providing instructions to identify the manufacturer, part number (P/N) and serial number (s/n) of the RAT actuator, and to modify the shimming procedure for the affected RAT actuator.

For the reasons described above, this [EASA] AD requires identification of the affected RAT actuators and, depending on its configuration (modified or not), the accomplishment of applicable corrective actions [modifying the RAT actuator. Additional actions include re-identifying the RAT actuator part number and RAT part number, as applicable].

You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2016-3983.

Comments

We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM and the FAA's response to each comment.

Request To Change Requirement From Modify To Replace

Delta Airlines (DAL) requested that the requirement to modify the RAT actuator in paragraphs (g)(2) and (g)(3) of the proposed AD be changed from “modify the RAT actuator” to “replace the RAT actuator.” DAL stated that operators cannot ensure that the removed RAT actuator would be modified by the RAT manufacturer by the compliance time specified in the proposed AD.

We agree to provide clarification regarding the requirement to modify the RAT actuator, but we do not agree with the commenter's request to change “modify” to “replace.” The modification procedures described in the Accomplishment Instructions of the Airbus service information specified in paragraphs (g)(2), (g)(3), (h)(2), and (h)(3) of this AD include more than just a modification. The modification procedures in the Airbus service information state to (1) remove the actuator from the RAT, (2) send the removed actuator to Hamilton Sundstrand, and (3) install the modified actuator on the RAT and re-identify the part number.

We also agree that operators do not have control over how long it would take Hamilton Sundstrand to modify the actuator, or if the modification could be completed prior to the applicable compliance times in this AD. Therefore, we have revised paragraphs (g)(2), (g)(3), (h)(2), and (h)(3) of this AD by removing the word “modify” and replacing it with “remove the actuator from the RAT, install a modified actuator, and re-identify the RAT . . . .”

Request To Include Review of Maintenance Records

DAL requested that paragraph (g) of the proposed AD be revised to include a statement that a review of airplane maintenance records is acceptable to determine the supplier, part number, and serial number of the installed RAT actuators if the supplier, part number, and serial number can be conclusively determined from that review. DAL stated that it has already modified airplanes in accordance with the Accomplishment Instructions of Airbus Service Bulletin A330-29-3126, dated June 12, 2014, and it tracks the on-wing identification of these RAT components. DAL indicated that allowing operators to review airplane maintenance records to determine the supplier, part number, and serial number of the installed RAT actuators would prevent unnecessary work.

We do not agree with the commenter's request. One of the actions included in the requirement to determine the supplier, part number, and serial number of an installed RAT actuator is looking at the actuator's identification plate. An inspection of the RAT actuator is necessary to determine if the identification plate is present. Paragraphs (g)(3) and (h)(3) of this AD require certain actions if the identification plate of a RAT actuator is missing. We have not changed this AD regarding this issue.

Request To Refer To Revised Service Information

DAL requested that the references to Hamilton Sundstrand Service Bulletin ERPS06M-29-21, dated May 27, 2014, be changed to ERPS06M-29-21, Revision 1, dated April 14, 2015. DAL noted that the revised service information updates the identification procedures for the RAT actuators, among other changes.

We agree with the commenter that all references to Hamilton Sundstrand Service Bulletin ERPS06M-29-21, dated May 27, 2014, should be changed to ERPS06M-29-21, Revision 1, dated April 14, 2015, in this final rule. We have made this change in the “Related Service Information under 1 CFR part 51” section in the preamble and paragraphs (g)(1), (g)(2), (g)(3), and (j) of this AD. We have also included a new paragraph (k) in this AD to provide credit for actions done prior to the effective date of this AD using Hamilton Sundstrand Service Bulletin ERPS06M-29-21, dated May 27, 2014. The subsequent paragraphs have been redesignated accordingly.

Request To Change References to a Certain Related AD

DAL noted that the “Related ADs” section of the NPRM preamble, and paragraphs (b) and (i) of the proposed AD, referred to AD 2015-26-02, Amendment 39-18350 (80 FR 81174, December 29, 2015) (“AD 2015-26-02”), which was superseded by AD 2016-04-01, Amendment 39-18395 (81 FR 8134, February 18, 2016) (“AD 2016-04-01”). DAL suggested that the references to AD 2015-26-02 be removed and replaced with references to AD 2016-04-01.

We agree with the commenter's suggestion. The “Related ADs” section of the NPRM is not restated in this final rule, but we have revised paragraphs (b) and (i) of this AD to refer to AD 2016-04-01.

Conclusion

We reviewed the relevant data, considered 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 minor changes:

• Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and
• Do not add any additional burden upon the public than was already proposed in the NPRM.

We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD.

Related Service Information Under 1 CFR Part 51

Airbus has issued the following service information, which describes procedures for identifying the supplier, part number, and serial number of the installed RAT actuator; modifying the RAT; and re-identifying the RAT actuator and RAT.

• Service Bulletin A330-29-3126, dated June 12, 2014.
• Service Bulletin A340-29-4097, dated June 12, 2014.
• Service Bulletin A340-29-5025, dated June 16, 2014.

Hamilton Sundstrand has issued Service Bulletins ERPS06M-29-21, Revision 1, dated April 14, 2015; and ERPS33T-29-7, dated June 6, 2014. This service information describes procedures for identifying the affected RAT actuator and RAT part numbers and serial numbers, modifying affected actuators, and re-identifying affected RAT actuators and RATs.

This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section.

Costs of Compliance

We estimate that this AD affects 84 airplanes of U.S. registry.

We estimate the following costs to comply with this AD:

Estimated Costs

Action	Labor cost	Parts cost	Cost per product	Cost on U.S. operators
Identification	1 work-hour × $85 per hour = $85	None	$85	$7,140

We estimate the following costs to do any necessary replacements that will be required based on the results of the required inspection. We have no way of determining the number of airplanes that might need these replacements:

On-Condition Costs

Action	Labor cost	Parts cost	Cost per product
Removal/installation/ re-identification	14 work-hours × $85 per hour = $1,190	$427,301	$428,491

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.
