Airworthiness Directives; Airbus, 22414-22417 [2018-10211]

Download as PDF daltland on DSKBBV9HB2PROD with PROPOSALS 22414 Federal Register / Vol. 83, No. 94 / Tuesday, May 15, 2018 / Proposed Rules Commission titled ‘‘Staff Activities Related to the Evaluation of Materials Cyber Security Vulnerabilities’’ (ADAMS Accession No. ML15201A509). This memorandum informed the Commission of the ongoing evaluation to determine the cyber security risk to each of the four sets of digital assets for risk-significant radioactive materials licensees, and described the twopronged approach focused on information gathering and consequence analysis that was used. As part of the information gathering effort, the NRC staff distributed a voluntary survey, ‘‘Questionnaire on Cyber Security at Byproduct Materials Licensees’’ (ADAMS Accession No. ML15246A306) on April 29, 2016, to all NRC and Agreement State licensees that possessed Category 1 and 2 quantities of radioactive materials. The purpose of the questionnaire was to identify what key digital assets existed at each licensee type, how they were connected to internal/external networks and the internet, and what technical and procedural security measures were in place for protection and operation of these systems and devices. The NRC staff also conducted outreach to stakeholders to encourage completion of the questionnaire, and site visits to manufacturers and panoramic irradiator licensees. The consequence analysis was conducted in parallel with the information gathering effort, and evaluated the potential for onsite and offsite consequences that could occur if the availability, integrity, or confidentiality of data or systems associated with nuclear materials were compromised by a cyber attack. Given the regulatory responsibilities of the U.S. Food and Drug Administration (FDA), the NRC limited its evaluation of the software systems used in medical applications to the systems related to the radiation safety and physical protection authority of the NRC. The NRC has a memorandum of understanding with the FDA that clarifies the respective roles of each agency in regulating the safe use of radiopharmaceuticals and sealed sources, and other medical devices containing radioactive material (ADAMS Accession No. ML023520399). Additional information on the FDA’s activities, role, and expectations for the continued cyber security of medical devices can be found at https:// www.fda.gov/downloads/ medicaldevices/digitalhealth/ ucm544684.pdf. On February 28, 2017, the NRC staff provided an update to the Commission on the status of agency activities VerDate Sep<11>2014 16:36 May 14, 2018 Jkt 244001 pertaining to cyber security at licensee facilities in a Commission paper, SECY– 17–0034, ‘‘Update to the U.S. Nuclear Regulatory Commission Cyber Security Roadmap’’ (ADAMS Accession No. ML16354A258). The update noted the NRC staff’s further consideration of cyber security requirements for radioactive materials licensees since the January 2016 memorandum. Additionally, the paper stated that the working group planned to complete its evaluation of the questionnaire responses, consequence analysis, and any follow-up communication with stakeholders and develop recommendations for a path forward. Subsequently, the NRC completed its evaluation of cyber security requirements for byproduct materials licensees in October 2017. The NRC staff concluded that byproduct materials licensees that possess risk-significant quantities of radioactive material do not rely solely on digital assets to ensure safety or physical protection. Rather, these licensees generally use a combination of measures, such as doors, locks, barriers, human resources, and operational processes, to ensure security, which reflects a defense-in-depth approach to physical protection and safety. As a result, the staff concluded that a compromise of any of the digital assets identified in the January 6, 2016, Commission memorandum would not result in a direct dispersal of risksignificant quantities of radioactive material, or exposure of individuals to radiation, without a concurrent and targeted breach of the physical protection measures in force for these licensees. Therefore, the NRC staff determined that the current cyber security threat and potential consequences do not warrant regulatory action. However, the NRC staff determined that it would be prudent to issue an Information Notice (IN) to communicate effective practices for cyber security to byproduct materials licensees possessing risk-significant quantities of radioactive material. The IN will provide licensees with a better understanding of contemporary cyber security issues and strategies to protect digital assets (e.g., computers, digital alarm systems), including those used to facilitate compliance with physical security requirements, such as those in 10 CFR part 37. The IN, which will reference existing cyber security guidance developed by the NRC’s Office of Nuclear Reactor Regulation and other Federal agencies, will be issued later in 2018. PO 00000 Frm 00002 Fmt 4702 Sfmt 4702 II. Conclusion For the reasons discussed in this document, the NRC is discontinuing rulemaking activity to develop cyber security requirements for byproduct materials licensees possessing risksignificant quantities of radioactive materials. In the next edition of the Unified Agenda, the NRC will update the entry for this rulemaking activity and refer to this document to indicate that the rulemaking has been discontinued. This rulemaking activity will appear in the ‘‘Completed Actions’’ section of the next edition of the Unified Agenda, but will not appear in future editions. If the NRC decides to pursue similar or related rulemaking activities in the future, it will inform the public through a new rulemaking entry in the Unified Agenda. Dated at Rockville, Maryland, this 10th day of May, 2018. For the Nuclear Regulatory Commission. Victor McCree, Executive Director for Operations.

Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2018–0031, dated January 31, 2018 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all Airbus Model A350–941 airplanes. The MCAI states: Following an inspection on the production line, paint peeling was found on forward and aft cargo door frame forks around the hook bolt hole. Subsequent investigations determined this had been caused by incorrect masking method during application of primer, top coat and Tartaric Sulfuric Anodizing (TSA) layer. As the cargo doors are located in an area with high corrosion sensitivity, where a surface protection with primer, top coat and TSA is specified, in case of paint peeling off, galvanic corrosion could develop. This condition, if not detected and corrected, could lead to cargo door failure, possibly resulting in decompression of the aeroplane and injury to occupants. To address this potential unsafe condition, Airbus identified the affected parts and issued the SB [Airbus Service Bulletin (SB) 22415 A350–52–P011, dated May 12, 2017] to provide inspection instructions. For the reasons described above, this [EASA] AD requires a one-time detailed [visual] inspection (DET) of the affected parts [for discrepancies] and, depending on findings, accomplishment of applicable corrective action(s) [i.e., restoration of the anti-corrosion protection of frame forks of affected parts]. 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– 0410. Related Service Information Under 1 CFR Part 51 Airbus has issued Airbus Service Bulletin A350–52–P011, dated May 12, 2017. This service information describes procedures for a one-time detailed visual inspection of the frame forks around the hook bolt hole on the forward and aft cargo door, and applicable corrective actions. 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 the same type design. Costs of Compliance We estimate that this proposed AD affects 9 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Labor cost Inspection .................................................. daltland on DSKBBV9HB2PROD with PROPOSALS Action Up to 9 work-hours × $85 per hour = $765. We estimate the following costs to do any necessary on-condition actions that VerDate Sep<11>2014 16:36 May 14, 2018 Jkt 244001 would be required based on the results of the proposed inspection. We have no PO 00000 Frm 00003 Fmt 4702 Cost per product Parts cost Sfmt 4702 $0 Up to $765 ..........

According to the manufacturer, all of the costs of this proposed 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 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. daltland on DSKBBV9HB2PROD with PROPOSALS 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: VerDate Sep<11>2014 16:36 May 14, 2018 Jkt 244001 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.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2018-0031, dated January 31, 2018 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for all Airbus Model A350-941 airplanes. 
The MCAI states:

    Following an inspection on the production line, paint peeling 
was found on forward and aft cargo door frame forks around the hook 
bolt hole. Subsequent investigations determined this had been caused 
by incorrect masking method during application of primer, top coat 
and Tartaric Sulfuric Anodizing (TSA) layer. As the cargo doors are 
located in an area with high corrosion sensitivity, where a surface 
protection with primer, top coat and TSA is specified, in case of 
paint peeling off, galvanic corrosion could develop.
    This condition, if not detected and corrected, could lead to 
cargo door failure, possibly resulting in decompression of the 
aeroplane and injury to occupants.
    To address this potential unsafe condition, Airbus identified 
the affected parts and issued the SB [Airbus Service Bulletin (SB) 
A350-52-P011, dated May 12, 2017] to provide inspection 
instructions.
    For the reasons described above, this [EASA] AD requires a one-
time detailed [visual] inspection (DET) of the affected parts [for 
discrepancies] and, depending on findings, accomplishment of 
applicable corrective action(s) [i.e., restoration of the anti-
corrosion protection of frame forks of affected parts].

0410.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Airbus Service Bulletin A350-52-P011, dated May 
12, 2017. This service information describes procedures for a one-time 
detailed visual inspection of the frame forks around the hook bolt hole 
on the forward and aft cargo door, and applicable corrective actions. 
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 the same 
type design.

Costs of Compliance

    We estimate that this proposed AD affects 9 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
            Action                Labor cost       Parts cost        Cost per product     Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Inspection...................  Up to 9 work-                 $0  Up to $765.............  Up to $6,885.
                                hours x $85 per
                                hour = $765.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary on-condition 
actions that would be required based on the results of the proposed 
inspection. We have no way of determining the number of aircraft that 
might need this action:

                                                 $765.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, all of the costs of this proposed 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 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.
