Airworthiness Directives; Airbus Airplanes, 18483-18485 [2018-08653]

Download as PDF jstallworth on DSKBBY8HB2PROD with PROPOSALS Federal Register / Vol. 83, No. 82 / Friday, April 27, 2018 / Proposed Rules now increased to $7.5 million due to adjustments for inflation, the 500employee manufacturing size standard set at the inception of SBA has remained the same. • Should SBA consider lowering its size standards? SBA receives periodic comments from the public that its standards are too high in certain industries or for certain types of Federal contracting opportunities. The comments generally concern the competitive edge that large small businesses have over the ‘‘truly small businesses’’ (a phrase heard frequently from commentators). This has always been a challenging issue, one that SBA has had to deal with over the years. SBA’s size standards appear large to the smallest of small businesses while larger small businesses often request even higher size standards. In the recently completed comprehensive size standards review, in view of weak economic conditions and various measures Federal Government implemented to stimulate employment and economic growth, SBA decided to not lower size standards even if the data supported lowering them. This issue is partly tied to Federal procurement trends of contracts getting larger over time, and they are often out of the reach of the ‘‘truly small businesses.’’ • Should SBA size standards be specific, i.e., to the precise dollar calculated based on the data and information it evaluates? Or should SBA recognize that there are other factors that go into establishing size standards, such as the fact that the data SBA evaluates is not static, industries change over the years, and even within a given year. • Should SBA round off its calculated size standards for the various industries? If so, should SBA always round up? To what level? If not, what about those industries that do not get increases in size standards when others are? What should be the cut-off point for rounding either one way or the other? • SBA’s new percentile approach to evaluating industry characteristics, which will replace the ‘‘anchor’’ size standards approach the Agency used in the past. • Alternative methodologies for determining small business size standards. • How SBA’s size standards impact competition in general and within a specific industry? • Alternative or additional factors that SBA should consider. • Whether SBA’s approach to small business size standards makes sense in the current economic environment. VerDate Sep<11>2014 14:38 Apr 26, 2018 Jkt 244001 • Whether there are gaps in SBA’s methodology because of the lack of comprehensive industry and Federal market data. • Alternative or other factors or data sources SBA should consider when establishing, reviewing, or modifying size standards. SBA encourages the public to review and comment on the Revised Methodology, which is available at https://www.sba.gov/size-standardsmethodology as well as at https:// www.regulations.gov. SBA will thoroughly evaluate and consider all comments and suggestions when finalizing the Revising Methodology, which the Agency will apply in the forthcoming, second five-five year review of size standards as required by the Jobs Act.

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 https:// 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: ESTIMATED COSTS Action Labor cost PBOV replacement .......................... 6 work-hours × $85 per hour = $510 ............................ jstallworth on DSKBBY8HB2PROD with PROPOSALS 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. VerDate Sep<11>2014 14:38 Apr 26, 2018 Jkt 244001 Parts cost 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.

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 https://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.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

[[Page 18485]]

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13   [Amended]

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

Airbus: Docket No. FAA-2018-0301; Product Identifier 2017-NM-112-AD.

(a) Comments Due Date

    We must receive comments by June 11, 2018.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to the Airbus airplanes identified in paragraphs 
(c)(1) through (c)(6) of this AD, certificated in any category, all 
manufacturer serial numbers.
    (1) Model A300 B2-1A, B2-1C, B2K-3C, B2-203, B4-2C, B4-103, and 
B4-203 airplanes.
    (2) Model A300 B4-601, B4-603, B4-620, and B4-622 airplanes.
    (3) Model A300 B4-605R and B4-622R airplanes.
    (4) Model A300 F4-605R and F4-622R airplanes.
    (5) Model A300 C4-605R Variant F airplanes.
    (6) Model A310-203, -204, -221, -222, -304, -322, -324, and -325 
airplanes.

(d) Subject

    Air Transport Association (ATA) of America Code 32, Landing 
gear.

(e) Reason

    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). We are issuing this AD to 
prevent 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.

(f) Compliance

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

(g) PBOV Replacement

    Within 60 months after the effective date of this AD, replace 
the PBOV having part number (P/N) A25315-1 with a PBOV having P/N 
A25315020-2, in accordance with the Accomplishment Instructions of 
Airbus Service Bulletin A300-32-0467, dated July 4, 2017; Airbus 
Service Bulletin A300-32-6117, dated July 4, 2017; or Airbus Service 
Bulletin A310-32-2151, dated July 4, 2017; as applicable.

(h) Parts Prohibition

    (1) After modification of an airplane as required by paragraph 
(g) of this AD, do not install any PBOV having P/N A25315-1 on that 
airplane.
    (2) For an airplane that, as of the effective date of this AD, 
has a PBOV having P/N A25315020-2 installed: As of the effective 
date of this AD do not install any PBOV having P/N A25315-1 on that 
airplane.

(i) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Section, Transport Standards Branch, FAA, has the 
authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, 
send your request to your principal inspector or local Flight 
Standards District Office, as appropriate. If sending information 
directly to the International Section, send it to the attention of 
the person identified in paragraph (j)(2) of this AD. Information 
may be emailed to: [email protected]. Before using any 
approved AMOC, notify your appropriate principal inspector, or 
lacking a principal inspector, the manager of the local flight 
standards district office/certificate holding district office.
    (2) Contacting the Manufacturer: For any requirement in this AD 
to obtain corrective actions from a manufacturer, the action must be 
accomplished using a method approved by the Manager, International 
Section, Transport Standards Branch, FAA; or the European Aviation 
Safety Agency (EASA); or Airbus's EASA Design Organization Approval 
(DOA). If approved by the DOA, the approval must include the DOA-
authorized signature.
    (3) Required for Compliance (RC): If any service information 
contains procedures or tests that are identified as RC, those 
procedures and tests must be done to comply with this AD; any 
procedures or tests that are not identified as RC are recommended. 
Those procedures and tests that are not identified as RC may be 
deviated from using accepted methods in accordance with the 
operator's maintenance or inspection program without obtaining 
approval of an AMOC, provided the procedures and tests identified as 
RC can be done and the airplane can be put back in an airworthy 
condition. Any substitutions or changes to procedures or tests 
identified as RC require approval of an AMOC.
