Background Transport Canada, which is the aviation authority for Canada, has issued Transport Canada Emergency AD CF–2024–28, dated August 1, 2024 (Transport Canada Emergency AD CF– 2024–28) (also referred to as the MCAI), to correct an unsafe condition for certain Model BD–500–1A10 and BD– 500–1A11 airplanes. The MCAI states that during scheduled maintenance of an in-service airplane, one of the pintle fuse pins (part number C01677412–001) in the LH MLG was discovered missing. Pintle fuse pins may also be damaged due to being incorrectly installed. If a missing or damaged pintle fuse pin is not discovered immediately, it would lead to a significant redistribution of loads in the MLG assembly and reduce the capability of the MLG assembly to withstand those loads. This condition, if not corrected, could potentially result in the total collapse of the MLG during takeoff. The FAA is issuing this AD to address the unsafe condition on these products. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2024–2131. Material Incorporated by Reference Under 1 CFR Part 51 Transport Canada Emergency AD CF– 2024–28 specifies procedures for performing a detail visual inspection of the MLG pintle housing assembly (leftand right-hand) for missing and incorrectly installed pintle fuse pins and corrective actions, if necessary. Corrective actions include contacting Airbus Canada Limited Partnership to report incorrectly installed or missing pintle fuse pins and to obtain approved disposition if any pintle fuse pins are missing or incorrectly installed. This E:\FR\FM\05SER1.SGM 05SER1 72313 Federal Register / Vol. 89, No. 172 / Thursday, September 5, 2024 / Rules and Regulations 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 this State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI referenced above. The FAA is issuing this AD after determining that the unsafe condition described previously 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 Transport Canada Emergency AD CF–2024–28 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, Transport Canada Emergency AD CF–2024–28 is incorporated by reference in this AD. This AD requires compliance with Transport Canada Emergency AD CF– 2024–28 in its entirety through that incorporation, except for any differences identified as exceptions in the regulatory text of this AD. Material required by Transport Canada Emergency AD CF–2024–28 for compliance will be available at regulations.gov under Docket No. FAA– 2024–2131 after this AD is published. Justification for Immediate Adoption and Determination of the Effective Date Section 553(b) of the Administrative Procedure Act (APA) (5 U.S.C. 551 et seq.) authorizes agencies to dispense with notice and comment procedures for rules when the agency, for ‘‘good cause,’’ finds that those procedures are ‘‘impracticable, unnecessary, or contrary to the public interest.’’ Under this section, an agency, upon finding good cause, may issue a final rule without providing notice and seeking comment prior to issuance. Further, section 553(d) of the APA authorizes agencies to make rules effective in less than thirty days, upon a finding of good cause. An unsafe condition exists that requires the immediate adoption of this AD without providing an opportunity for public comments prior to adoption. The FAA has found that the risk to the flying public justifies forgoing notice and comment prior to adoption of this rule because Transport Canada issued an emergency AD stating that there was a missing pintle fuse pin discovered during scheduled maintenance. A missing or damaged pintle fuse pin would lead to a significant redistribution of loads in the MLG assembly and reduce the capability of the MLG assembly to withstand those loads, potentially resulting in the total collapse of the MLG during takeoff. Additionally, the compliance time in this AD is shorter than the time necessary for the public to comment and for publication of the final rule. Accordingly, notice and opportunity for prior public comment are impracticable and contrary to the public interest pursuant to 5 U.S.C. 553(b). In addition, 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, for the same reasons the FAA found good cause to forgo notice and comment. Regulatory Flexibility Act (RFA) The requirements of the RFA do not apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and comment. Because the FAA has determined that it has good cause to adopt this rule without notice and comment, RFA analysis is not required. Costs of Compliance The FAA estimates that this AD affects 129 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 1 work-hour × $85 per hour = $85 .............................................................................................. $0 $85 $10,965 The FAA estimates the following costs to do any necessary on-condition actions that would be required based on the results of any required actions. The FAA has no way of determining the number of aircraft that might need these on-condition actions: ESTIMATED COSTS OF ON-CONDITION ACTIONS Labor cost Parts cost Cost per product 2 work-hours × $85 per hour = $170 ...................................................................................................................... * $3,500 $3,670 khammond on DSKJM1Z7X2PROD with RULES * There are 8 pintle fuse pins per airplane. The FAA has no way of determining the number of pins that might need to be installed on each airplane. According to the manufacturer, some or all of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. The FAA does not control warranty coverage for affected VerDate Sep<11>2014 21:04 Sep 04, 2024 Jkt 262001 individuals. As a result, the FAA has included all known costs in the 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. 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. khammond on DSKJM1Z7X2PROD with RULES 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, and (2) Will not affect intrastate aviation in Alaska.

The Food and Drug Administration (FDA or we) is classifying the heparin and direct oral factor Xa inhibitor drug test system into class II (special controls). The special controls that apply to the device type are identified in this order and will be part of the codified language for the heparin and direct oral factor Xa inhibitor drug test system’s classification. We are taking this action because we have determined that classifying the device into class II (special controls) will provide a reasonable assurance of safety and effectiveness of the device. We believe this action will also enhance patients’ access to beneficial innovative devices. DATES: This order is effective September 5, 2024. The classification was applicable on September 17, 2020.

SUMMARY: SUPPLEMENTARY INFORMATION: I. Background Upon request, FDA has classified the heparin and direct oral factor Xa inhibitor drug test system as class II (special controls), which we have determined will provide a reasonable assurance of safety and effectiveness. The automatic assignment of class III occurs by operation of law and without any action by FDA, regardless of the level of risk posed by the new device. Any device that was not in commercial distribution before May 28, 1976, is automatically classified as, and remains within, class III and requires premarket approval unless and until FDA takes an action to classify or reclassify the device (see 21 U.S.C. 360c(f)(1)). We refer to these devices as ‘‘postamendments devices’’ because they were not in commercial distribution prior to the date of enactment of the Medical Device Amendments of 1976, which amended the Federal Food, Drug, and Cosmetic Act (FD&C Act). FDA may take a variety of actions in appropriate circumstances to classify or reclassify a device into class I or II. We may issue an order finding a new device to be substantially equivalent under section 513(i) of the FD&C Act (see 21 U.S.C. 360c(i)) to a predicate device that does not require premarket approval. We determine whether a new device is substantially equivalent to a predicate device by means of the procedures for E:\FR\FM\05SER1.SGM 05SER1

    CBI is commercial or financial information that is both customarily 
and actually treated as private by its owner. Under the Freedom of 
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public 
disclosure. If your comments responsive to this AD contain commercial 
or financial information that is customarily treated as private, that 
you actually treat as private, and that is relevant or responsive to 
this AD, it is important that you clearly designate the submitted 
comments as CBI. Please mark each page of your submission containing 
CBI as ``PROPIN.'' The FAA will treat such marked submissions as 
confidential under the FOIA, and they will not be placed in the public 
docket of this AD. Submissions containing CBI should be sent to Fatin 
Saumik, Aviation Safety Engineer, FAA, 1600 Stewart Avenue, Suite 410, 
Westbury, NY 11590; telephone 516-228-7300; email [email protected]. Any commentary that the FAA receives which is not 
specifically designated as CBI will be placed in the public docket for 
this rulemaking.

Background

    Transport Canada, which is the aviation authority for Canada, has 
issued Transport Canada Emergency AD CF-2024-28, dated August 1, 2024 
(Transport Canada Emergency AD CF-2024-28) (also referred to as the 
MCAI), to correct an unsafe condition for certain Model BD-500-1A10 and 
BD-500-1A11 airplanes. The MCAI states that during scheduled 
maintenance of an in-service airplane, one of the pintle fuse pins 
(part number C01677412-001) in the LH MLG was discovered missing. 
Pintle fuse pins may also be damaged due to being incorrectly 
installed. If a missing or damaged pintle fuse pin is not discovered 
immediately, it would lead to a significant redistribution of loads in 
the MLG assembly and reduce the capability of the MLG assembly to 
withstand those loads. This condition, if not corrected, could 
potentially result in the total collapse of the MLG during takeoff.
    The FAA is issuing this AD to address the unsafe condition on these 
products.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2024-2131.

Material Incorporated by Reference Under 1 CFR Part 51

    Transport Canada Emergency AD CF-2024-28 specifies procedures for 
performing a detail visual inspection of the MLG pintle housing 
assembly (left- and right-hand) for missing and incorrectly installed 
pintle fuse pins and corrective actions, if necessary. Corrective 
actions include contacting Airbus Canada Limited Partnership to report 
incorrectly installed or missing pintle fuse pins and to obtain 
approved disposition if any pintle fuse pins are missing or incorrectly 
installed. This

[[Page 72313]]

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 this State of Design Authority, it 
has notified the FAA of the unsafe condition described in the MCAI 
referenced above. The FAA is issuing this AD after determining that the 
unsafe condition described previously 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 Transport 
Canada Emergency AD CF-2024-28 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, 
Transport Canada Emergency AD CF-2024-28 is incorporated by reference 
in this AD. This AD requires compliance with Transport Canada Emergency 
AD CF-2024-28 in its entirety through that incorporation, except for 
any differences identified as exceptions in the regulatory text of this 
AD. Material required by Transport Canada Emergency AD CF-2024-28 for 
compliance will be available at regulations.gov under Docket No. FAA-
2024-2131 after this AD is published.

Justification for Immediate Adoption and Determination of the Effective 
Date

    Section 553(b) of the Administrative Procedure Act (APA) (5 U.S.C. 
551 et seq.) authorizes agencies to dispense with notice and comment 
procedures for rules when the agency, for ``good cause,'' finds that 
those procedures are ``impracticable, unnecessary, or contrary to the 
public interest.'' Under this section, an agency, upon finding good 
cause, may issue a final rule without providing notice and seeking 
comment prior to issuance. Further, section 553(d) of the APA 
authorizes agencies to make rules effective in less than thirty days, 
upon a finding of good cause.
    An unsafe condition exists that requires the immediate adoption of 
this AD without providing an opportunity for public comments prior to 
adoption. The FAA has found that the risk to the flying public 
justifies forgoing notice and comment prior to adoption of this rule 
because Transport Canada issued an emergency AD stating that there was 
a missing pintle fuse pin discovered during scheduled maintenance. A 
missing or damaged pintle fuse pin would lead to a significant 
redistribution of loads in the MLG assembly and reduce the capability 
of the MLG assembly to withstand those loads, potentially resulting in 
the total collapse of the MLG during takeoff. Additionally, the 
compliance time in this AD is shorter than the time necessary for the 
public to comment and for publication of the final rule. Accordingly, 
notice and opportunity for prior public comment are impracticable and 
contrary to the public interest pursuant to 5 U.S.C. 553(b).
    In addition, 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, 
for the same reasons the FAA found good cause to forgo notice and 
comment.

Regulatory Flexibility Act (RFA)

    The requirements of the RFA do not apply when an agency finds good 
cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and 
comment. Because the FAA has determined that it has good cause to adopt 
this rule without notice and comment, RFA analysis is not required.

Costs of Compliance

    The FAA estimates that this AD affects 129 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
1 work-hour x $85 per hour = $85.............................              $0              $85          $10,965
----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary on-
condition actions that would be required based on the results of any 
required actions. The FAA has no way of determining the number of 
aircraft that might need these on-condition actions:

                 Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
                                                             Cost per
              Labor cost                   Parts cost        product
------------------------------------------------------------------------
2 work-hours x $85 per hour = $170....        * $3,500           $3,670
------------------------------------------------------------------------
* There are 8 pintle fuse pins per airplane. The FAA has no way of
  determining the number of pins that might need to be installed on each
  airplane.

    According to the manufacturer, some or all of the costs of this AD 
may be covered under warranty, thereby reducing the cost impact on 
affected individuals. The FAA does not control warranty coverage for 
affected individuals. As a result, the FAA has included all known costs 
in the cost estimate.

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 a penalty for 
failure to comply with a collection of information subject to the

[[Page 72314]]

requirements of the Paperwork Reduction Act unless that collection of 
information displays a currently valid OMB Control Number. The OMB 
Control Number for this information collection is 2120-0056. Public 
reporting for this collection of information is estimated to take 
approximately 1 hour per response, including the 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

    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.
