Airworthiness Directives; Airbus SAS Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Airbus SAS Model A330-200, A330-200 Freighter, and A330-300 series 
airplanes. This AD was prompted by reports of dual flight management 
system (FMS) resets with the loss of flight plan (F-PLN) data. This AD 
requires revising the airplane flight manual (AFM) to prohibit required 
navigation performance-authorization required (RNP-AR) operations using 
flight management guidance envelope computer (FMGEC) standard P5H3. 
This AD would also require modifying the FMS software of airplanes 
equipped with FMGEC standard P5H3. We are issuing this AD to address 
the unsafe condition on these products.

DATES: This AD is effective January 16, 2019.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of January 16, 
2019.

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 all Airbus SAS Model A330-
200, A330-200 Freighter, and A330-300 series airplanes. The NPRM 
published in the Federal Register on July 18, 2018 (83 FR 33873). The 
NPRM was prompted by reports of dual FMS resets with the loss of F-PLN 
data. The NPRM proposed to require revising the AFM to prohibit RNP-AR 
operations using FMGEC standard P5H3. The NPRM also proposed to require 
modifying the FMS software of airplanes equipped with FMGEC standard 
P5H3.
    We are issuing this AD to address dual FMS reset and loss of F-PLN 
data, which in the context of RNP-AR operations of the airplane could 
result in significantly reduced situational awareness of proximity to 
terrain and/or other aircraft to below acceptable safety margins, and 
out of the context of RNP-AR operations could lead to an unusually high 
pilot workload.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2017-0233, dated November 23, 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, Model 
A330-200 Freighter, and Model A330-300 series airplanes. The MCAI 
states:

    Operators of [Airbus SAS Model] A330 aeroplanes fitted with a 
Flight Management Guidance Envelope Computer (FMGEC) standard P5H3 
have reported some occurrences of dual Flight Management System 
(FMS) reset with the loss of Flight Plan (F-PLN) data. These events 
have been identified in all flight phases, including Take-Off 
transition.
    This condition, if not corrected, particularly in the context of 
Required Navigation Performance--Authorization Required (RNP-AR) 
operations of the aeroplane, could lead to a large reduction in 
safety margins due to terrain and/or surrounded traffic proximity 
[below acceptable safety margins], and out of the context of RNP-AR 
operations could lead to an increased pilot workload.
    To address this potential unsafe condition, Airbus issued 
Aircraft Flight Manual (AFM) Temporary Revision (TR) 774 issue 1 
[approved October 13, 2017, to the Airbus A330/A340 Airplane Flight 
Manual] to provide instructions to prohibit RNP-AR operations. In 
addition, Airbus developed modification (mod) 207362 to allow FMS 
software downgrading from P5 to P4A standard, and issued [Airbus 
SAS] Alert Operator Transmission (AOT) A22L002-17 providing 
instructions to implement that mod on in-service aeroplanes. As a 
long term action, Airbus intend to publish Service Bulletin (SB) 
A330-22-3264, which will supersede AOT A22L002-17 [dated October 20, 
2017], to provide the same instructions for FMS software downgrade.
    For the reasons described above, this [EASA] AD requires 
amendment of the applicable AFM and operating the aeroplane 
accordingly, and requires FMS software downgrading of aeroplanes 
with FMGEC standard P5H3.

    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-
0584.

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 NRPM

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

Request To Revise Applicability

    Delta Air Lines (DAL) requested that we revise the applicability of 
the proposed AD to state that the AD is not effective for airplanes 
that have a Thales FMS installed. DAL justified the request by stating 
that the applicability of the proposed AD was too general, and removing 
airplanes with a Thales FMS installed from the applicability would not 
result in a decrease in safety, because the action is intended only for 
airplanes with a Honeywell FMS installed.
    We disagree with DAL's request because FMGEC standard P5H3 can be 
embodied in production or in service on both Thales and Honeywell FMS. 
Further, this AD requires modification of Groups 1 and 2 airplanes in 
accordance with Airbus Service Bulletin A330-22-3264, dated March 14, 
2018, which requires prior or simultaneous accomplishment of 
prerequisite Airbus SAS service information applicable to airplanes 
with a Honeywell FMS, Release 2, or a Thales flight guidance card. We 
have not changed this AD in this regard.

Request To Develop New Software Standard

    ALPA suggested that a temporary downgrade of the FMS software from 
P5H3 standard to P4A standard is a short-term fix, and recommended that 
a new software standard be developed. ALPA contends that the new 
software standard should eliminate the potential of dual FMS resets, 
which could lead to loss of flight plan data, while incorporating the 
features of the advanced P5H3 standard.
    We disagree with ALPA's request. The unsafe condition of dual FMS 
resets, which could lead to loss of flight plan data, was introduced by 
the FMS software P5H3 standard. The unsafe condition is eliminated by 
downgrading the FMS software to P4A standard, which is a permanent 
repair. The FAA acknowledges ALPA's recommendation, and we might 
consider further rulemaking on this issue if Airbus proposes new 
software. We have not changed the 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.

    We estimate that this AD affects 3 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
3 work-hours x $85 per hour = $255...........................              $0             $255             $765
----------------------------------------------------------------------------------------------------------------

    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.
