PO 00000 Frm 00003 Fmt 4700 46533 Sfmt 4700 Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian AD CF–2019–38, dated October 30, 2019 (also referred to as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Bombardier, Inc., Model BD–700–1A10 and BD–700– 1A11 airplanes. 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–2020–0104. The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Bombardier, Inc., Model BD–700–1A10 and BD–700–1A11 airplanes. The NPRM published in the Federal Register on February 24, 2020 (85 FR 10346). The NPRM was prompted by a report that the antifretting coating on the piston rods of certain RAT deployment actuators may have been incorrectly applied. The NPRM proposed to require a review of airplane maintenance records or an inspection of the RAT deployment actuator to determine the serial number and, depending on the findings, replacement with an upgraded RAT deployment actuator. The FAA is issuing this AD to address incorrect application of the anti-fretting coating that may lead to galling of the piston rod over time, which could cause the unit to seize and fail to fully deploy. This condition which, if not corrected, could result in the inability to power essential systems in the event that other sources of power are also lost. See the MCAI for additional background information. Comment The FAA gave the public the opportunity to participate in developing this final rule. The following presents the comment received on the NPRM and the FAA’s response. Request To Require Testing of the AntiFretting Coating in Lieu of Inspection Paul Risenhoover questioned why the FAA doesn’t require testing instead of the inspection of the anti-fretting coating on the piston rods of certain ram air turbine (RAT) deployment actuators. The commenter did not provide justification for his request. The FAA infers that the commenter was requesting testing of the RAT deployment actuator in lieu of an inspection of the anti-fretting coating on the piston rods. The FAA disagrees with the commenter’s request. This AD E:\FR\FM\03AUR1.SGM 03AUR1 46534 Federal Register / Vol. 85, No. 149 / Monday, August 3, 2020 / Rules and Regulations requires an inspection of the RAT deployment actuator to determine the serial number, not an inspection of the anti-fretting coating on the piston rods. If the inspection reveals the RAT deployment actuator is an older model, the actuator needs to be replaced, regardless of it passing any test. The older RAT deployment actuator models are susceptible to failure due to the antifretting coating not being applied correctly to the piston rods. Even if the RAT deployment actuator passed a test, it would still be susceptible to failure in the future. The FAA finds it necessary to issue this AD as proposed. Conclusion The FAA reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting this final rule as proposed, except for minor editorial changes. The FAA has determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM. Related Service Information Under 1 CFR Part 51 Bombardier has issued the following service information, which describes procedures for inspecting the RAT deployment actuator to identify the serial number and replacing certain RAT deployment actuators with upgraded parts. These documents are distinct since they apply to different airplane models with different configurations. • Bombardier Service Bulletin 700– 1A11–24–029, dated February 22, 2019. • Bombardier Service Bulletin 700– 24–090, dated February 22, 2019. • Bombardier Service Bulletin 700– 24–5015, dated February 22, 2019. • Bombardier Service Bulletin 700– 24–6015, dated February 22, 2019. 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. Costs of Compliance The FAA estimates that this AD affects 380 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: ESTIMATED COSTS FOR REQUIRED ACTION Labor cost Parts cost Cost per product Cost on U.S. operators 1 work-hour × $85 per hour = $85 .............................................................................................. $0 $85 $32,300 ESTIMATED COSTS OF ON-CONDITION ACTIONS Labor cost Parts cost 5 work-hours × $85 per hour = $425 .................................... Up to $41,006 ...................................................................... khammond on DSKJM1Z7X2PROD with RULES 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 operators. The FAA does not control warranty coverage for affected operators. 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.

Temporary final rule. AGENCY: ACTION: The Coast Guard is establishing a temporary safety zone on the waters of the St. Clair River in the vicinity of Port Huron, MI. This zone is intended to restrict and control movement of vessels in a portion of the St. Clair River. Though this is an unsanctioned, non-permitted marine event, this zone is necessary to provide for the safety of life on the navigable waters during a float down event near Port Huron, MI.

FOR FURTHER INFORMATION CONTACT: SUPPLEMENTARY INFORMATION: I. Table of Abbreviations CFR Code of Federal Regulations COTP Captain of the Port Detroit DHS Department of Homeland Security FR Federal Register NPRM Notice of Proposed Rulemaking § Section U.S.C. United States Code II. Background Information and Regulatory History During the afternoon of August 16, 2020, a non-sanctioned public event is scheduled to take place. The event is advertised over various social-media sites, in which a large number of persons float down a segment of the St. Clair River, using inner tubes and other similar floatation devices. The 2020 float down event will occur between approximately 12 noon and 8 p.m. on August 16, 2020. This non-sanctioned event has taken place in the month of August annually since 2009. No private or municipal entity requested a marine event permit from the Coast Guard for this event, and it has not received state or federal permits since its inception. The event has drawn over 5,000 participants of various ages annually. Despite plans put together by federal, state and local officials, emergency responders and law enforcement officials have been overburdened pursuing safety during this event. Medical emergencies, people drifting across the international border, and people trespassing on residential property when trying to get out of the water before the designated finish line are some of the numerous difficulties encountered during the float down event. During the 2014 float-down event, a 19-year-old participant died. During the 2016 float down, a wind shift caused thousands of U.S. citizen rafters with no passports to drift into Canadian waters. The current and wind made it impossible for the rafters to paddle back into U.S. waters, necessitating significant coordination with the Canadian authorities. Despite these events, promotional information for the event continues to be published. More than 5,000 people are again anticipated to float down the river this year. No public or private organization holds themselves responsible as the event sponsor. PO 00000 Frm 00006 Fmt 4700 Sfmt 4700 The Coast Guard is issuing this temporary rule without prior notice and opportunity to comment pursuant to authority under section 4(a) of the Administrative Procedure Act (APA) (5 U.S.C. 553(b)). This provision authorizes an agency to issue a rule without prior notice and opportunity to comment when the agency for good cause finds that those procedures are ‘‘impracticable, unnecessary, or contrary to the public interest.’’ Under 5 U.S.C. 553(b) (B), the Coast Guard finds that good cause exists for not publishing a notice of proposed rulemaking (NPRM) with respect to this rule because doing so would be impracticable. The Coast Guard did not receive the final details of this float down event in time to publish an NPRM. As such, it is impracticable to publish an NPRM because we lack sufficient time to provide a reasonable comment period and then consider those comments before issuing the rule. Moreover, delaying the effective date of this rule to wait for a comment period to run would be impracticable and contrary to the public interest because it would inhibit the Coast Guard’s ability to protect the public and vessels from the hazards associated with the float down event. Under 5 U.S.C. 553(d)(3), the Coast Guard finds that good cause exists for making this rule effective less than 30 days after publication in the Federal Register. Delaying the effective date of this rule would be contrary to public interest because prompt action is needed to protect the public and participants in this event on August 16, 2020. III. Legal Authority and Need for Rule The Coast Guard is issuing this rule under authority in 46 U.S.C. 70034 (previously 33 U.S.C. 1231). The Captain of the Port Detroit (COTP) has determined the float down poses significant risk to public safety and property from 12 noon through 8 p.m. on August 16, 2020. The likely combination of large numbers of participants, strong river currents, limited rescue resources, and difficult emergency response scenarios could easily result in serious injuries or fatalities to float down participants and spectators. Therefore, the COTP is establishing a safety zone around the event location to help minimize risks to safety of life and property during this event. IV. Discussion of the Rule This rule establishes a safety zone from 12 noon through 8 p.m. on August 16, 2020. The safety zone will begin at Lighthouse Beach and encompass all E:\FR\FM\03AUR1.SGM 03AUR1

SUPPLEMENTARY INFORMATION:

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2019-38, dated October 
30, 2019 (also referred to as the Mandatory Continuing Airworthiness 
Information, or ``the MCAI''), to correct an unsafe condition for 
certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. 
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-2020-

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to certain Bombardier, 
Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. The NPRM published 
in the Federal Register on February 24, 2020 (85 FR 10346). The NPRM 
was prompted by a report that the anti-fretting coating on the piston 
rods of certain RAT deployment actuators may have been incorrectly 
applied. The NPRM proposed to require a review of airplane maintenance 
records or an inspection of the RAT deployment actuator to determine 
the serial number and, depending on the findings, replacement with an 
upgraded RAT deployment actuator. The FAA is issuing this AD to address 
incorrect application of the anti-fretting coating that may lead to 
galling of the piston rod over time, which could cause the unit to 
seize and fail to fully deploy. This condition which, if not corrected, 
could result in the inability to power essential systems in the event 
that other sources of power are also lost. See the MCAI for additional 
background information.

Comment

    The FAA gave the public the opportunity to participate in 
developing this final rule. The following presents the comment received 
on the NPRM and the FAA's response.

Request To Require Testing of the Anti-Fretting Coating in Lieu of 
Inspection

    Paul Risenhoover questioned why the FAA doesn't require testing 
instead of the inspection of the anti-fretting coating on the piston 
rods of certain ram air turbine (RAT) deployment actuators. The 
commenter did not provide justification for his request.
    The FAA infers that the commenter was requesting testing of the RAT 
deployment actuator in lieu of an inspection of the anti-fretting 
coating on the piston rods. The FAA disagrees with the commenter's 
request. This AD

[[Page 46534]]

requires an inspection of the RAT deployment actuator to determine the 
serial number, not an inspection of the anti-fretting coating on the 
piston rods. If the inspection reveals the RAT deployment actuator is 
an older model, the actuator needs to be replaced, regardless of it 
passing any test. The older RAT deployment actuator models are 
susceptible to failure due to the anti-fretting coating not being 
applied correctly to the piston rods. Even if the RAT deployment 
actuator passed a test, it would still be susceptible to failure in the 
future. The FAA finds it necessary to issue this AD as proposed.

Conclusion

    The FAA reviewed the relevant data, considered the comment 
received, and determined that air safety and the public interest 
require adopting this final rule as proposed, except for minor 
editorial changes. The FAA has determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

    The FAA estimates that this AD affects 380 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                       Estimated Costs for Required Action
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------

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


                                     Estimated Costs of On-Condition Actions
----------------------------------------------------------------------------------------------------------------
               Labor cost                            Parts cost                       Cost per product
----------------------------------------------------------------------------------------------------------------
5 work-hours x $85 per hour = $425......  Up to $41,006..................  Up to $41,431.
----------------------------------------------------------------------------------------------------------------

    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 operators. The FAA does not control warranty coverage for 
affected operators. 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.

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,
    (2) Will not affect intrastate aviation in Alaska, and
    (3) 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.

on the piston rods of certain ram air turbine (RAT) deployment 
actuators may have been incorrectly applied. Incorrect application 
of this anti-fretting coating may lead to galling of the piston rod 
over time, which could cause the unit to seize and fail to fully 
deploy. The FAA is issuing this AD to address this condition which, 
if not corrected, could result in the inability to power essential 
systems in the event that other sources of power are also lost.

(f) Compliance

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