Airworthiness Directives; Airbus SAS Airplanes

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

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are superseding Airworthiness Directive (AD) 2015-02-17, 
which applied to all Airbus Model A330-200, A330-200 Freighter, and 
A330-300 series airplanes. AD 2015-02-17 required revising the 
electrical emergency configuration procedure in the Emergency 
Procedures section of the airplane flight manual (AFM) to include 
procedures for deploying the ram air turbine manually to provide 
sufficient hydraulic power and avoid constant speed motor/generator 
(CSM/G) shedding. Since we issued AD 2015-02-17, we have determined 
that replacement or modification of the two flight warning computers 
(FWCs) is necessary to address the identified unsafe condition. This AD 
requires the replacement or modifications of the two FWCs. This AD also 
removes airplanes from the applicability. We are issuing this AD to 
address the unsafe condition on these products.

DATES: This AD is effective October 5, 2018.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of October 5, 
2018.
    The Director of the Federal Register approved the incorporation by

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2015-02-17,

[[Page 44458]]

Amendment 39-18084 (80 FR 4762, January 29, 2015) (``AD 2015-02-17''). 
AD 2015-02-17 applied to all Airbus Model A330-200, A330-200 Freighter, 
and A330-300 series airplanes. The NPRM published in the Federal 
Register on April 16, 2018 (83 FR 16248). The NPRM was prompted by a 
determination that replacement or modification of the two FWCs is 
necessary to address the identified unsafe condition. The NPRM proposed 
to require the replacement or modification of the two FWCs. The NPRM 
also proposed to remove airplanes from the applicability. We are 
issuing this AD to address the identified unsafe condition.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2017-0105R1, dated July 17, 2017 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for all Airbus SAS Model A330-200, A330-200 
Freighter, and A330-300 series airplanes. The MCAI states:

    The Constant Speed Motor/Generator (CSM/G), as installed on 
Airbus A330 aeroplanes, is qualified for an overload condition of 
9.5 kVA [kilovolt-ampere] for 30 minutes. This duration is 
sufficient to perform safe landing and go-around. However, 
electrical load analysis revealed that the hydraulic power might not 
be sufficient to supply the CSM/G during slat/flap extension, when 
only one engine is running.
    This condition, if not corrected, and in conjunction with the 
loss of main system, could lead to a scenario where the crew is not 
clearly warned that the electrical system has switched on the 
battery and thus has a limited duration to support a safe landing.
    To initially address this potential unsafe condition, Airbus 
issued an Aircraft Flight Manual (AFM) Temporary Revision (TR) to 
amend the electrical emergency configuration ``ELEC EMER CONFIG'' 
procedure to require the pilot to deploy the ram air turbine 
manually before setting the Landing Recovery to ``ON'' position, 
which provides sufficient hydraulic power and avoids CSM/G shedding 
under worst-case operational conditions. Consequently, EASA issued 
AD 2014-0273 to require amendment of the AFM by incorporating the 
applicable Airbus TR.
    After finding that [EASA] AD 2014-0273 contained some incorrect 
and incomplete information, EASA issued AD 2014-0281 [which 
corresponds to FAA AD 2015-02-17], retaining the requirements of 
EASA AD 2014-0273, which was superseded, but correcting the 
information related to premod/pre Service Bulletin (SB) or post-mod/
post SB aeroplane configurations.
    Since EASA AD 2014-0281 was issued, in order to improve the 
``ELEC EMER CONFIG'' procedure, Airbus developed modifications to 
install improved FWCs, which is embodied in production through 
Airbus modification (mod) 205228, and to be embodied in service with 
Airbus SB A330-31-3232 * * *.
    For the reasons described above, this [EASA] AD retains the 
requirements of EASA AD 2014-0281, which is superseded, and requires 
installation of a software standard upgrade [or replacement] of the 
two FWCs and removal of the applicable AFM TR once the aeroplane is 
modified.
    Since EASA AD 2017-0105 was issued, it was identified that there 
was no need to require removal of applicable AFM TR, nor 
incorporation of a later AFM revision, as the contents are 
identical. This revised [EASA] AD deletes the requirement of 
paragraph (3) [of EASA AD 2017-0105].

0169.

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

Request for Additional Credit

    Delta Air Lines requested that paragraph (l) of the proposed AD, 
``Credit for Previous Actions,'' include Airbus Service Bulletin A330-
31-3232, Revision 01, dated February 14, 2017, as well as Airbus 
Service Bulletin A330-31-3232, dated May 4, 2016.
    We disagree this change is necessary. Paragraph (f) of this AD 
requires compliance with this AD unless already done. Paragraph (j) of 
this AD mandates actions in accordance with Airbus Service Bulletin 
A330-31-3232, Revision 01, dated February 14, 2017. Therefore, as 
specified in paragraph (f) of this AD, having previously accomplished 
the actions specified in Airbus Service Bulletin A330-31-3232, Revision 
01, dated February 14, 2017, means compliance with paragraph (j) of 
this AD has already been established. In paragraph (l) of this AD, we 
give credit to operators that have previously accomplished an earlier 
revision of the required service information identified in paragraph 
(j) of this AD; therefore, as specified in paragraph (l) of this AD, 
having accomplished Airbus Service Bulletin A330-31-3232, dated May 4, 
2016, prior to the effective date of this AD means compliance with 
paragraph (j) of this AD has already been established. 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
     Do not 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 A330/A340 Airplane Flight Manual (AFM) 
Temporary Revision (TR) TR427, UPDATE OF ELEC--EMER CONFIG PROCEDURE, 
Issue 1.0, dated November 7, 2014; and A330/A340 AFM TR TR428, UPDATE 
OF ELEC--EMER CONFIG PROCEDURE, Issue 1.0, dated November 7, 2014. This 
service information describes updated electrical emergency 
configuration procedures in the AFM. This service information is 
distinct because it applies to airplanes in different configurations.
    Airbus SAS has issued Service Bulletin A330-31-3232, Revision 01, 
including Appendix 01, dated February 14, 2017. This service 
information describes procedures for replacement or modification of the 
FWCs.
    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 105 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

[[Page 44459]]



                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
4 work-hour x $85 per hour = $340............................              $0             $340          $35,700
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some 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 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

    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.

(d) Subject

    Air Transport Association (ATA) of America Code 24, Electrical 
power.

(e) Reason

    This AD was prompted by an electrical load analysis that 
revealed that hydraulic power might not be sufficient to supply the 
constant speed motor/generator (CSM/G) during slat/flap extension 
when only one engine is running and a determination that replacement 
or modification of the two flight warning computers (FWCs) is 
necessary to address the identified unsafe condition. We are issuing 
this AD to prevent such a condition which, in conjunction with the 
loss of the main electrical system, could lead to the scenario where 
the flight crew is not clearly warned that the electrical system has 
switched on the battery and thus has a limited duration that would 
allow a safe landing.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Retained Airplane Flight Manual (AFM) Revision, With a New 
Exception

    This paragraph restates the requirements of paragraph (g) of AD 
2015-02-17, with a new exception. Except for airplanes identified in 
paragraph (h) of this AD: Within 15 days after February 13, 2015 
(the effective date of AD 2015-02-17), revise the Emergency 
Procedures section of the Airbus A330/A340 AFM to include the 
information in the applicable Airbus temporary revision (TR) 
specified in paragraph (g)(1) or (g)(2) of this AD. This may be done 
by inserting a copy of the applicable TR specified in paragraph 
(g)(1) or (g)(2) of this AD into the AFM. Operate the airplane 
according to the procedures in the applicable TR. When the 
information in the applicable TR has been included in the general 
revisions of the AFM, the general revisions may be inserted into the 
AFM, provided the relevant information in the general revision is 
identical to that in the TR, and the TR may be removed.
    (1) For airplanes in Airbus pre-modification 47930 configuration 
and pre-Airbus Service Bulletin A330-28-3067 configuration: Airbus
