CEDAS allows maintenance personnel to wirelessly connect to the ECUs and allows autonomous engine data uploads to cloud data services over WiFi. later date for a supplemental type certificate to modify any other model included on Type Certificate No. T00005NY to incorporate the same novel or unusual design feature, these special conditions would apply to that model as well. Discussion The Honeywell supplemental type certificate for the Bombardier Model BD–100–1A10 airplane design adds the Connected Engine Data Access System (CEDAS) architecture which is novel for commercial transport category airplanes. CEDAS allows connection to airplane electronic systems and networks, and access from aircraft external sources (e.g., operator networks, wireless devices, internet connectivity, service provider satellite communications, electronic flight bags, etc.) to the previously isolated airplane electronic assets (networks, systems, and databases). The CEDAS design introduces the potential for unauthorized access to these previously isolated airplane electronic systems and networks by persons inside the airplane. The installation of CEDAS may result in network security vulnerabilities from intentional or unintentional corruption of data and systems required for the operations and maintenance of the airplane. The existing FAA regulations did not anticipate these networked airplane system architectures. Furthermore, these regulations and the current guidance material do not address potential security vulnerabilities, which could be exploited by unauthorized access to airplane networks, data buses, and servers. Therefore, these special conditions ensure that the security (i.e., confidentiality, integrity, and availability) of airplane systems will not be compromised by unauthorized wired or wireless connections from within the airplane. These special conditions also require the applicant to provide appropriate instructions to the operator to maintain all electronic system safeguards that have been implemented as part of the original network design so that this feature does not allow or reintroduce security threats. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards. Conclusion Applicability As discussed above, these special conditions are applicable to the Bombardier Model BD–100–1A10 airplane. Should Honeywell apply at a VerDate Sep<11>2014 15:56 Oct 28, 2021 Jkt 256001 List of Subjects in 14 CFR Part 25 Aircraft, Aviation safety, Reporting and recordkeeping requirements. Authority Citation The authority citation for these special conditions is as follows: Authority: 49 U.S.C. 106(f), 106(g), 40113, 44701, 44702, 44704. The Special Conditions Accordingly, pursuant to the authority delegated to me by the Administrator, the following special conditions are issued as part of the type certification basis for the Bombardier Model BD–100–1A10 airplane, as modified by Honeywell, for electronic system security protection from unauthorized internal access. 1. The applicant must ensure that the design provides isolation from, or airplane electronic system security protection against, access by unauthorized sources internal to the airplane. The design must prevent inadvertent and malicious changes to, and all adverse impacts upon, airplane equipment, systems, networks, or other assets required for safe flight and operations. 2. The applicant must establish appropriate procedures to allow the operator to ensure that continued airworthiness of the airplane is maintained, including all post type certification modifications that may have an impact on the approved electronic system security safeguards.

Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2021–0059, dated March 2, 2021 (EASA AD 2021– 0059) (also referred to as the MCAI), to correct an unsafe condition for certain Model F28 Mark 0070 and Mark 0100 airplanes. This AD was prompted by a report of exfoliation corrosion found during an inspection of the wing front spar lower boom. This corrosion was found between wing station (WSTA) 3100 and WSTA 3600. It was determined that corrosion may also exist at other spanwise positions on the wing front spar lower boom. The FAA is issuing this AD to address corrosion, which if not corrected, could lead to reduced structural integrity of the wing structure and reduced wing ultimate and limit load capability. See the MCAI for additional background information. Related Service Information Under 1 CFR Part 51 EASA AD 2021–0059 specifies procedures for a detailed inspection for corrosion of the wing front spar lower boom between WSTA 1825 and WSTA 10110, corrective actions (repair and restoration of the surface corrosion), and sending an inspection report to Fokker Services B.V. This material 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 This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to the PO 00000 Frm 00005 Fmt 4700 Sfmt 4700 59843 FAA’s bilateral agreement with the State of Design Authority, the FAA has been notified of the unsafe condition described in the MCAI described above. The FAA is issuing this AD after determining that the unsafe condition exists and is likely to exist or develop on other products of the same type design. Requirements of This AD This AD requires accomplishing the actions specified in the MCAI described previously, except for any differences identified as exceptions in the regulatory text of this AD. Explanation of Required Compliance Information In the FAA’s ongoing efforts to improve the efficiency of the AD process, the FAA developed a process to use some civil aviation authority (CAA) ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has been coordinating this process with manufacturers and CAAs. As a result, EASA AD 2021–0059 is incorporated by reference in this AD. This AD requires compliance with EASA AD 2021–0059 in its entirety through that incorporation, except for any differences identified as exceptions in the regulatory text of this AD. Using common terms that are the same as the heading of a particular section in EASA AD 2021–0059 does not mean that operators need comply only with that section. For example, where the AD requirement refers to ‘‘all required actions and compliance times,’’ compliance with this AD requirement is not limited to the section titled ‘‘Required Action(s) and Compliance Time(s)’’ in EASA AD 2021–0059. Service information required by EASA AD 2021–0059 for compliance will be available at https://www.regulations.gov by searching for and locating Docket No. FAA–2021–0840 after this AD is published. Interim Action The FAA considers this AD interim action. The inspection reports that are required by this AD will enable the manufacturer to re-evaluate the current 12-year visual inspection interval of the front spar front side. Once final action has been identified, the FAA might consider further rulemaking. FAA’s Justification and Determination of the Effective Date There are currently no domestic operators of these products. Accordingly, notice and opportunity for prior public comment are unnecessary, E:\FR\FM\29OCR1.SGM 29OCR1 59844 Federal Register / Vol. 86, No. 207 / Friday, October 29, 2021 / Rules and Regulations pursuant to 5 U.S.C. 553(b)(3). In addition, for the foregoing reason, the FAA finds that good cause exists pursuant to 5 U.S.C. 553(d) for making this amendment effective in less than 30 days. Regulatory Flexibility Act (RFA) There are currently no domestic operators of these products. Accordingly, notice and opportunity for prior public comment are unnecessary, pursuant to 5 U.S.C. 553(b)(3)(B). In addition, for the foregoing reason(s), the FAA finds that good cause exists pursuant to 5 U.S.C. 553(d) for making this amendment effective in less than 30 days. Costs of Compliance Currently, there are no affected U.S.registered airplanes. If an affected airplane is imported and placed on the U.S. Register in the future, the FAA provides the following cost estimates to comply with this AD: ESTIMATED COSTS FOR REQUIRED ACTIONS * Labor cost Parts cost Cost per product 28 work-hours × $85 per hour = $2,380 ................................................................................................................. $0 $2,380 *Table does not include estimated costs for reporting. The FAA estimates that it takes about 1 work-hour per product to comply with the reporting requirement in this AD. The average labor rate is $85 per hour. Based on these figures, the FAA estimates the cost of reporting the inspection results on U.S. operators to be $0, or $85 per product. The FAA has received no definitive data on which to base the cost estimates for the on-condition actions specified in this AD. khammond on DSKJM1Z7X2PROD with RULES Paperwork Reduction Act A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB control number. The control number for the collection of information required by this AD is 2120–0056. Public reporting for this collection of information is estimated to take approximately 1 hour per response, including time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. All responses to this collection of information are mandatory. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden, to: Information Collection Clearance Officer, Federal Aviation Administration, 10101 Hillwood Parkway, Fort Worth, TX 76177–1524. the FAA Administrator. Subtitle VII: Aviation Programs, describes in more detail the scope of the Agency’s authority. The FAA is 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. Regulatory Findings The FAA determined that 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, and (2) Will not affect intrastate aviation in Alaska.

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2021-0059, dated March 2, 2021 (EASA 
AD 2021-0059) (also referred to as the MCAI), to correct an unsafe 
condition for certain Model F28 Mark 0070 and Mark 0100 airplanes.
    This AD was prompted by a report of exfoliation corrosion found 
during an inspection of the wing front spar lower boom. This corrosion 
was found between wing station (WSTA) 3100 and WSTA 3600. It was 
determined that corrosion may also exist at other spanwise positions on 
the wing front spar lower boom. The FAA is issuing this AD to address 
corrosion, which if not corrected, could lead to reduced structural 
integrity of the wing structure and reduced wing ultimate and limit 
load capability. See the MCAI for additional background information.

Related Service Information Under 1 CFR Part 51

    EASA AD 2021-0059 specifies procedures for a detailed inspection 
for corrosion of the wing front spar lower boom between WSTA 1825 and 
WSTA 10110, corrective actions (repair and restoration of the surface 
corrosion), and sending an inspection report to Fokker Services B.V. 
This material 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

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to the FAA's bilateral agreement with the State of Design Authority, 
the FAA has been notified of the unsafe condition described in the MCAI 
described above. The FAA is issuing this AD after determining that the 
unsafe condition exists and is likely to exist or develop on other 
products of the same type design.

Requirements of This AD

    This AD requires accomplishing the actions specified in the MCAI 
described previously, except for any differences identified as 
exceptions in the regulatory text of this AD.

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA developed a process to use some civil aviation 
authority (CAA) ADs as the primary source of information for compliance 
with requirements for corresponding FAA ADs. The FAA has been 
coordinating this process with manufacturers and CAAs. As a result, 
EASA AD 2021-0059 is incorporated by reference in this AD. This AD 
requires compliance with EASA AD 2021-0059 in its entirety through that 
incorporation, except for any differences identified as exceptions in 
the regulatory text of this AD. Using common terms that are the same as 
the heading of a particular section in EASA AD 2021-0059 does not mean 
that operators need comply only with that section. For example, where 
the AD requirement refers to ``all required actions and compliance 
times,'' compliance with this AD requirement is not limited to the 
section titled ``Required Action(s) and Compliance Time(s)'' in EASA AD 
2021-0059. Service information required by EASA AD 2021-0059 for 
compliance will be available at https://www.regulations.gov by 
searching for and locating Docket No. FAA-2021-0840 after this AD is 
published.

Interim Action

    The FAA considers this AD interim action. The inspection reports 
that are required by this AD will enable the manufacturer to re-
evaluate the current 12-year visual inspection interval of the front 
spar front side. Once final action has been identified, the FAA might 
consider further rulemaking.

FAA's Justification and Determination of the Effective Date

    There are currently no domestic operators of these products. 
Accordingly, notice and opportunity for prior public comment are 
unnecessary,

[[Page 59844]]

pursuant to 5 U.S.C. 553(b)(3). In addition, for the foregoing reason, 
the FAA finds that good cause exists pursuant to 5 U.S.C. 553(d) for 
making this amendment effective in less than 30 days.

Regulatory Flexibility Act (RFA)

    There are currently no domestic operators of these products. 
Accordingly, notice and opportunity for prior public comment are 
unnecessary, pursuant to 5 U.S.C. 553(b)(3)(B). In addition, for the 
foregoing reason(s), the FAA finds that good cause exists pursuant to 5 
U.S.C. 553(d) for making this amendment effective in less than 30 days.

Costs of Compliance

    Currently, there are no affected U.S.-registered airplanes. If an 
affected airplane is imported and placed on the U.S. Register in the 
future, the FAA provides the following cost estimates to comply with 
this AD:

                 Estimated Costs for Required Actions *
------------------------------------------------------------------------
                                                             Cost per
              Labor cost                   Parts cost        product
------------------------------------------------------------------------
28 work-hours x $85 per hour = $2,380.              $0           $2,380
------------------------------------------------------------------------
*Table does not include estimated costs for reporting.

    The FAA estimates that it takes about 1 work-hour per product to 
comply with the reporting requirement in this AD. The average labor 
rate is $85 per hour. Based on these figures, the FAA estimates the 
cost of reporting the inspection results on U.S. operators to be $0, or 
$85 per product.
    The FAA has received no definitive data on which to base the cost 
estimates for the on-condition actions specified in this AD.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB control number. The control 
number for the collection of information required by this AD is 2120-
0056. Public reporting for this collection of information is estimated 
to take approximately 1 hour per response, including time for reviewing 
instructions, searching existing data sources, gathering and 
maintaining the data needed, and completing and reviewing the 
collection of information. All responses to this collection of 
information are mandatory. Send comments regarding this burden estimate 
or any other aspect of this collection of information, including 
suggestions for reducing this burden, to: Information Collection 
Clearance Officer, Federal Aviation Administration, 10101 Hillwood 
Parkway, Fort Worth, TX 76177-1524.

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.
    The FAA is 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.

Regulatory Findings

    The FAA determined that 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, and
    (2) Will not affect intrastate aviation in Alaska.
