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 A300 series airplanes; Model A300 B4-600, B4-600R, and 
F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes 
(collectively called Model A300-600 series airplanes); and Model A310 
series airplanes. This AD was prompted by a report of yellow hydraulic 
system failure, including both braking accumulators, due to failure of 
the parking brake operated valve (PBOV). This AD requires replacement 
of a certain PBOV with a different PBOV. We are issuing this AD to 
address the unsafe condition on these products.

DATES: This AD is effective November 13, 2018.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of November 13, 
2018.

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 A300 
series airplanes; Model A300 B4-600, A300 B4-600R, and F4-600R series 
airplanes, and Model A300 C4-605R Variant F airplanes (collectively 
called Model A300-600 series airplanes); and Model A310 series 
airplanes. The NPRM published in the Federal Register on April 27, 2018 
(83 FR 18483). The NPRM was prompted by a report of yellow hydraulic 
system failure, including both braking accumulators, due to failure of 
the PBOV. The NPRM proposed to require replacement of a certain PBOV 
with a different PBOV.
    We are issuing this AD to address failure of the PBOV, which could 
result in no braking capability during ground operations, possibly 
leading to damage to the airplane and injury to people on the ground.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2017-0153, dated August 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 A300 series 
airplanes; Model A300 B4-600, B4-600R, and F4-600R series airplanes, 
and Model A300 C4-605R Variant F airplanes (collectively called Model 
A300-600 series airplanes); and Model A310 series airplanes. The MCAI 
states:

    An occurrence was reported where yellow hydraulic system, 
including both braking accumulators, was lost. This was confirmed by 
ECAM [electronic centralized aircraft monitor] warnings and single 
chimes during taxiing. Normal braking on green hydraulic circuit was 
used until aeroplane stopped at parking position. A few seconds 
later, the aeroplane slowly accelerated, until colliding with a wall 
and a bus. The crew reported that the parking brake was selected and 
full braking pedals were applied, but with no effect since normal 
braking was inhibited after Parking Brake was set to ON. 
Investigation results identified that this occurrence was due to 
failure of the parking brake operated valve (PBOV), Part Number (P/
N) A25315-1.
    This condition [parking brake failure], if not corrected, could 
lead to further incidents, possibly resulting in damage to the 
aeroplane and injury to persons on the ground.
    Prompted by this event, Airbus issued Service Bulletin (SB) 
A300-32-0467, SB A310-32-2151, SB A300-32-6117 and SB A300-32-9023, 
as applicable, to provide instructions for in-service installation 
of the PBOV P/N A25315020-2 introduced by Airbus Modification 13201 
for A300/A310/A300-600 and Airbus Modification 19601 for A300-600ST.
    For the reason described above, this [EASA] AD requires 
replacement of the PBOV P/N A25315-1 by PBOV P/N A25315020-2.

    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-
0301.

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) indicated its 
support for the NPRM.

[[Page 50483]]

Request To Revise the Compliance Time in the Proposed AD

    Airbus requested that the compliance time of the proposed AD be 
revised so operators would have all required actions completed by 
August 31, 2022, instead of 60 months after the effective date of the 
final rule. Airbus noted that August 31, 2022, is the calendar date 
that corresponds with the compliance time in EASA AD 2017-0153, which 
is 60 months after August 31, 2017 (the effective date of EASA AD 2017-
0153).
    We disagree with the commenter's request. In consideration of the 
average utilization rate by the affected U.S. operators, the practical 
aspects of an orderly modification of the U.S. fleet during regular 
maintenance periods, and the availability of required parts, we have 
determined that a 60-month compliance time is appropriate. However, 
most ADs, including this one, permit operators to accomplish the 
requirements of an AD at a time earlier then the specified compliance 
time.
    Furthermore, using the compliance time proposed by Airbus would 
effectively reduce the compliance time for this AD, and we would have 
to provide an additional public comment period, which would further 
delay the issuance of this AD. We have not changed this AD in regard to 
this issue.

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 Service Bulletin A300-32-0467, dated July 4, 
2017; Service Bulletin A300-32-6117, dated July 4, 2017; and Service 
Bulletin A310-32-2151, dated July 4, 2017. This service information 
describes procedures for replacing the PBOV. These documents are 
distinct since they apply to different airplane models. 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 147 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:

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.
