[Docket No. FAA-2018-0301; Product Identifier 2017-NM-112-AD]
RIN 2120-AA64


Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
Airbus 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 proposed 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 proposed AD 
would require replacement of a certain PBOV with a different PBOV. We 
are proposing this AD to address the unsafe condition on these 
products.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 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 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.

Related Service Information Under 1 CFR Part 51

    Airbus 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.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of these 
same type designs.

Costs of Compliance

    We estimate that this proposed AD affects 147 airplanes of U.S. 
registry. We estimate the following costs to comply with this proposed 
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 proposed 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 to the Director of the System Oversight 
Division.

Regulatory Findings

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    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.
