AD 2018-21-07

We are adopting a new airworthiness directive (AD) for certain Airbus SAS Model A330-200 Freighter, -200, and -300 series airplanes. This AD was prompted by reports of Angle of Attack (AOA) blockages not detected by upgraded flight control primary computer (FCPC) software standards. This AD requires upgrading certain FCPCs, which terminates a certain airplane flight manual revision for certain airplanes. We are issuing this AD to address the unsafe condition on these products.

Final rule.

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 SAS Model A330-200 Freighter, -200, and -300 series airplanes. The NPRM published in the Federal Register on June 4, 2018 (83 FR 25595). The NPRM was prompted by reports of AOA blockages not detected by upgraded FCPC software standards. The NPRM proposed to require upgrading certain FCPCs, which would terminate a certain airplane flight

[[Page 51826]]

manual revision for certain airplanes. We are issuing this AD to address Alpha protection activation due to blocked AOA probes, which could result in reduced controllability of the airplane.
The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2017-0246R1, dated April 6, 2018 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for certain Airbus SAS Model A330-200 Freighter, -200, and -300 series airplanes. The MCAI states:

In 2015, occurrences were reported of multiple Angle of Attack (AOA) blockages. Investigation results indicated the need for AOA monitoring in order to better detect cases of AOA blockage.
This condition, if not corrected, could, under specific circumstances, lead to undue activation of the Alpha protection, possibly resulting in reduced control of the aeroplane.
To address this potential unsafe condition, Airbus developed new FCPC software standards for enhanced AOA monitoring and, consequently, EASA issued AD 2015-0124 (later revised) [which corresponds to FAA AD 2016-25-30, Amendment 39-18756, (82 FR 1175, January 5, 2017) (``AD 2016-25-30'')] to require these software standard upgrades.
Since EASA AD 2015-0124R3 was issued, it was identified that, for some cases, AOA blockages were not detected by those FCPC software standards. Consequently,new FCPC software standards, as specified in Table 1 of this [EASA] AD, have been developed (Airbus modification (mod) 206412, mod 206413 and mod 206414) to further improve the detection of AOA blockage. Airbus issued Service Bulletin (SB) A330-27-3222 and SB A330-27-3223 to implement these mods on in-service aeroplanes. Consequently, EASA issued AD 2017- 0246 to require a software standard upgrade of the three FCPCs, either by modification or replacement.
Since that [EASA] AD was issued, it was determined that the Aircraft Flight Manual (AFM) Emergency Procedure, as previously required by EASA AD 2014-0267-E [which corresponds to FAA AD 2014- 25-52, Amendment 39-18066, (80 FR 3161, January 22, 2015) (``AD 2014-25-52'')] can also be removed for other AOA sensors and FCPC configurations. This [EASA] AD revises paragraph (2) accordingly, also introducing Table 2 for that purpose.

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-2018- 0498.

Comments

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

Support for the NPRM

The Air Line Pilots Association, International (ALPA) expressed support for the NPRM.

Request To Change Applicability

Delta Air Lines (Delta) asked that we further restrict the applicability identified in paragraph (c) of the proposed AD by including the effectivity in the referenced service information. Delta stated that operators should be held accountable only for airplanes on which an airworthiness concern exists, and those airplanes correspond to the effectivity of the referenced service information. Delta added that if there are airplanes outside of this effectivity, operators will incur costs to produce and maintain records for those airplanes, regardless of whether or not there is an unsafe condition. Delta asserted that the service information provides a list of production airplanes that will be, or will have been, delivered with the affected software.
We do agree to clarify the applicability. This AD is applicable to airplanes equipped with certain FCPC and not only to specific airplane manufacturer serial numbers (MSNs). For airplanes equipped with certain FCPC, only those that are in a pre-mod configuration as specified in paragraph (g) of this AD are required to do the upgrade specified in paragraph (h) of this AD. Airplanes in a post-mod configuration are not required to do an upgrade; however, they must comply with paragraph (k) of this AD. Paragraph (k) of this AD prohibits the installation of any software or hardware of a standard earlier than one listed in table 1 to paragraphs (h) and (k) of this AD on all airplanes identified in paragraph (c) of this AD. In order for this installation prohibition to be effective, airplanes in a post-mod configuration must be included in the applicability. We are also matching the applicability in the MCAI. Therefore, we have not changed this AD in this regard.

Request To Remove Reference to Group 2 Airplanes

Delta asked that we remove references to Group 2 airplanes from paragraphs (g) and (k) of the proposed AD, ``Definition of Groups'' and ``Parts Installation Prohibition,'' respectively. Delta stated that Group 1 airplanes are those in pre-mod 206412, 206413, or 206414 configuration, as applicable; Group 2 airplanes are those in post-mod 206412, 206413, or 206414 configuration, as applicable. Delta added that Group 2 airplanes are those that do not require modification, since they are already equipped with the FCPC software; therefore, those airplanes should be excluded from the applicability since the unsafe condition does not exist on those airplanes. Delta noted that a Group 1/Group 2 definition is redundant to the applicability paragraph because that paragraph defines only those airplanes onwhich the unsafe condition exists. Delta also noted that the proposed language in paragraph (k) of the proposed AD would allow continued installation of existing hardware/software before the AD effective date and prohibit removal of the modification after the effective date of the AD.
We do not agree with the commenter's request. Airplanes in Groups 1 and 2 represent the total of the airplanes identified in paragraph (c) of the AD. Group 1 and Group 2 are defined in paragraph (g) of this AD to distinguish one from another, for the purpose of identifying the applicable requirements. Removing the definition of Group 2 airplanes from paragraph (g) of this AD would not remove Group 2 airplanes from the applicability. Airplanes in Group 2 may in the future be subject to the unsafe condition identified in this AD if an earlier standard of software or hardware is installed on that airplane. Therefore, so that Group 2 airplanes remain in an airworthy configuration after the effective dateof the AD, paragraph (k) of this AD prohibits the installation of any software or hardware of a standard earlier than that listed in table 1 to paragraphs (h) and (k) of this AD. Therefore, we have not changed this AD in this regard.

Request To Reference to Later Revisions of Service Information

Delta asked that we change paragraph (h) of the proposed AD to allow use of subsequent service bulletins. Delta stated that the FCPC software standard has changed approximately every two years. Delta noted that adding the term ``or relative later software standard'' will allow operators to immediately install the latest software standard without having to request an alternative method of compliance (AMOC).
We disagree with the commenter's request. In general terms, we are required by the Office of the Federal Register (OFR) regulations to either publish the service document contents as part of the actual AD language; or submit the service document to the OFR for approval as ``referenced'' material, in which case we may only refer to such material in the text of an AD. The AD may refer to the service document only if the OFR approved it for

[[Page 51827]]

``incorporation by reference.'' See 1 CFR part 51.
To allow operators to use later revisions of the referenced document (issued after publication of the AD), either we must revise the AD to reference specific later revisions, or operators must request approval to use later revisions or later software standards as an AMOC for this AD under the provisions of paragraph (l)(1) of this AD. We have not changed this AD in this regard.

Conclusion

We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this final rule as proposed, except for minor editorial changes. We have determined that these minor changes:
Are consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and
Donot add any additional burden upon the public than was already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

Airbus SAS has issued the following service information:
Service Bulletin A330-27-3222, dated February 16, 2017.
Service Bulletin A330-27-3223, dated June 6, 2017.
This service information describes procedures for upgrading (by modification or replacement, as applicable) certain FCPCs. These documents are distinct since they apply to different airplanes in different configurations. 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 103 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:

Estimated Costs ----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- Modification/replacement........... 3 work-hours x $85 per hour $0 $255 $26,265
= $255. ----------------------------------------------------------------------------------------------------------------

According to the manufacturer, some or all of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all known costs in our cost estimate.

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.
This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes and associated appliances to the Director of the System Oversight Division.

Regulatory Findings

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.
