Airworthiness Directives; Bombardier, Inc., Airplanes, 21443-21446 [2024-06521]

Download as PDF ddrumheller on DSK120RN23PROD with PROPOSALS1 Federal Register / Vol. 89, No. 61 / Thursday, March 28, 2024 / Proposed Rules ($34.0 million in annual sales), using two-year average data, and assuming that the 2 handlers are about the same size. In a large crop year, one or both handlers could be considered large handlers, depending on the proportion of the crop that each of the handlers processed. This proposal would decrease the assessment rate collected from handlers for the 2024 fiscal year and subsequent fiscal years from $35 to $28 per ton of assessable olives. The Committee unanimously recommended 2024 expenditures of $1,100,151 and an assessment rate of $28 per ton. The recommended assessment rate of $28 is $7 lower than the 2023 assessment rate. The quantity of assessable olives harvested in the 2023 crop year is estimated to be 34,000 tons, compared to 19,912 tons in 2022. Olives are an alternate-bearing crop, with a small crop (2022) followed by a large crop (2023). Income derived from the $28 per ton assessment rate, along with interest income and funds from the authorized reserve, would be adequate to meet this fiscal year’s budgeted expenditures. The major expenditures recommended by the Committee for the 2024 fiscal year include $350,250 for program administration, $164,650 for export programs, $197,500 for marketing activities, $302,751 for research, and $85,000 for inspection. Budgeted expenses for these items during the 2023 fiscal year were $399,700, $148,000, $193,000, $325,712, and $88,000, respectively. The Committee deliberated on many of the expenses, weighed the relative value of various programs or projects, and decreased their expenses for inspection and research activities while increasing marketing activities. Overall, the 2024 budget of $1,100,151 is $54,261 less than the $1,154,412 budgeted for the 2023 fiscal year. Prior to arriving at this budget and assessment rate, the Committee considered information from various sources including the Committee’s Executive, Marketing, Inspection, and Research Subcommittees. Alternate expenditure levels were discussed by these groups, based upon the relative value of various projects to the olive industry and the increased olive production. The assessment rate of $28 per ton of assessable olives was derived by considering anticipated expenses, the high volume of assessable olives, the current balance in the monetary reserve, and additional pertinent factors. A review of information from NASS indicates that the average producer price for the 2022 crop year (the most recent year for which information is VerDate Sep<11>2014 17:37 Mar 27, 2024 Jkt 262001 available) was $913 per ton. Therefore, utilizing the recommended assessment rate of $28 per ton, assessment revenue for the 2024 fiscal year as a percentage of total producer revenue would be approximately 3.1 percent ($28 divided by $913 times 100). This proposed action would decrease the assessment obligation imposed on handlers. Assessments are applied uniformly on all handlers. Some of the assessment costs to handlers may be passed on to producers. Decreasing the assessment rate would reduce the burden on handlers and may also, therefore, reduce the burden on producers. The Committee’s meetings are widely publicized throughout the production area. The olive industry and all interested persons are invited to attend the meetings and participate in Committee deliberations on all issues. Like all Committee meetings, the December 12, 2023, meeting was a public meeting and all entities, both large and small, were able to express views on this issue. In addition, interested persons are invited to submit comments on this proposed rule, including the regulatory and information collection impacts of this action on small businesses. In accordance with the Paperwork Reduction Act of 1995, (44 U.S.C. Chapter 35), the Order’s information collection requirements have been previously approved by OMB and assigned OMB No. 0581–0178 Vegetable and Specialty Crops. No changes in those requirements as a result of this action are necessary. Should any changes become necessary, they would be submitted to OMB for approval. This proposed rule would not impose any additional reporting or recordkeeping requirements on either small or large California olive handlers. As with all Federal marketing order programs, reports and forms are periodically reviewed to reduce information requirements and duplication by industry and public sector agencies. AMS is committed to complying with the E-Government Act to promote the use of the internet and other information technologies to provide increased opportunities for citizen access to Government information and services, and for other purposes. USDA has not identified any relevant Federal rules that duplicate, overlap, or conflict with this action. A small business guide on complying with fruit, vegetable, and specialty crop marketing agreements and orders may be viewed at: https:// www.ams.usda.gov/rules-regulations/ PO 00000 Frm 00003 Fmt 4702 Sfmt 4702 21443 moa/small-businesses. Any questions about the compliance guide should be sent to Richard Lower at the previously mentioned address in the FOR FURTHER INFORMATION CONTACT section. After consideration of all relevant material presented, including the information and recommendations submitted by the Committee and other available information, USDA has determined that this proposed rule is consistent with, and would effectuate the purposes of, the Act. A 30-day comment period is provided to allow interested persons to respond to this proposed rule. All written comments timely received will be considered before a final determination is made on this rule.

SUPPLEMENTARY INFORMATION: ddrumheller on DSK120RN23PROD with PROPOSALS1 DATES: VerDate Sep<11>2014 17:37 Mar 27, 2024 Jkt 262001 Comments Invited The FAA invites you to send any written relevant data, views, or arguments about this proposal. Send your comments to an address listed under ADDRESSES. Include ‘‘Docket No. FAA–2024–0767; Project Identifier MCAI–2023–00723–T’’ at the beginning of your comments. The most helpful comments reference a specific portion of the proposal, explain the reason for any recommended change, and include supporting data. The FAA will consider all comments received by the closing date and may amend the proposal because of those comments. Except for Confidential Business Information (CBI) as described in the following paragraph, and other information as described in 14 CFR 11.35, the FAA will post all comments received, without change, to regulations.gov, including any personal information you provide. The agency will also post a report summarizing each substantive verbal contact received about this NPRM. Confidential Business Information 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 NPRM 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 NPRM, 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 NPRM. Submissions containing CBI should be sent to William Reisenauer, Aviation Safety Engineer, FAA, 1600 Stewart Avenue, Suite 410, Westbury, NY 11590; phone: 516–228–7300; email: 9-avs-nyaco-cos@faa.gov. 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 AD CF–2023– 36, dated May 29, 2023 (Transport Canada AD CF–2023–36) (also referred to after this as the MCAI), to correct an unsafe condition on certain Bombardier, Inc., Model BD–700–2A12 airplanes. PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 The MCAI states that during the execution of a functional test procedure (FTP) during production, the baggage bay discharge PBA switch was partially engaged and failed to make electrical contact. Further investigation showed that in some instances, the baggage bay discharge PBA switch was making contact but was not fully engaged and the tabs were not fully locked, so while the PBA may pass the FTP, vibration could eventually lead to a loss of electrical contact and subsequent loss of baggage bay discharge PBA switch functionality. The FAA is issuing this AD to address the possible inability to discharge halon into the baggage compartment in case of a fire. The unsafe condition, if not addressed, could result in the inability to control a baggage compartment fire. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2024–0767. Related Service Information Under 1 CFR Part 51 The FAA reviewed Bombardier Service Bulletin 700–26–7505, dated February 10, 2023. This service information specifies procedures for doing a general visual inspection of the baggage bay discharge PBA switch for proper installation and a functional operation test. 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 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 and service information referenced above. The FAA is issuing this NPRM after determining that the unsafe condition described previously is likely to exist or develop on other products of the same type design. Proposed AD Requirements in This NPRM This proposed AD would require accomplishing the actions specified in the service information already described. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 42 airplanes of U.S. registry. The FAA E:\FR\FM\28MRP1.SGM 28MRP1 Federal Register / Vol. 89, No. 61 / Thursday, March 28, 2024 / Proposed Rules 21445 estimates the following costs to comply with this proposed AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 2 work-hours × $85 per hour = $170 .......................................................................................... $0 $170 $7,140 The FAA has included all known costs in its cost estimate. According to the manufacturer, however, some or all of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected operators. 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. ddrumheller on DSK120RN23PROD with PROPOSALS1 Regulatory Findings The FAA 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) Would not affect intrastate aviation in Alaska, and (3) Would not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

Any commentary that the FAA receives that is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background The FAA has received reports indicating multiple findings of cracks in the fuselage skin common to the UWL on all series of Boeing Model 777 airplanes. The crack findings were made during UWL replacement or accomplishing Boeing Service Bulletins 777–53–0084 or 777–53–0087, or Boeing Requirements Bulletin 777–57A0122 RB. In many of the fuselage skin crack reports, the UWL was reported not damaged. The found fuselage skin cracks were hidden externally by the UWL, and internally by fuselage frames and stringers. The fuselage skin cracks were found on airplanes with as few as 2,000 total flight cycles and 18,000 total flight hours. These fuselage skin cracks were determined to be caused by cold work surface upset that is not removed from the mating parts and high joint load transfer or significant local bending stresses at critical fastener locations. These conditions, if not addressed, could result in an inability of a principal structural element (PSE) to sustain limit load, leading to reduced structural integrity of the airplane and possible loss of control of the airplane.

the proposal because of those comments.
    Except for Confidential Business Information (CBI) as described in 
the following paragraph, and other information as described in 14 CFR 
11.35, the FAA will post all comments received, without change, to 
regulations.gov, including any personal information you provide. The 
agency will also post a report summarizing each substantive verbal 
contact received about this NPRM.

Confidential Business Information

    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 NPRM 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 NPRM, 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 NPRM. Submissions containing CBI should be sent to 
William Reisenauer, Aviation Safety Engineer, FAA, 1600 Stewart Avenue, 
Suite 410, Westbury, NY 11590; phone: 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 AD CF-2023-36, dated May 29, 2023 (Transport 
Canada AD CF-2023-36) (also referred to after this as the MCAI), to 
correct an unsafe condition on certain Bombardier, Inc., Model BD-700-
2A12 airplanes. The MCAI states that during the execution of a 
functional test procedure (FTP) during production, the baggage bay 
discharge PBA switch was partially engaged and failed to make 
electrical contact. Further investigation showed that in some 
instances, the baggage bay discharge PBA switch was making contact but 
was not fully engaged and the tabs were not fully locked, so while the 
PBA may pass the FTP, vibration could eventually lead to a loss of 
electrical contact and subsequent loss of baggage bay discharge PBA 
switch functionality.
    The FAA is issuing this AD to address the possible inability to 
discharge halon into the baggage compartment in case of a fire. The 
unsafe condition, if not addressed, could result in the inability to 
control a baggage compartment fire.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2024-0767.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Bombardier Service Bulletin 700-26-7505, dated 
February 10, 2023. This service information specifies procedures for 
doing a general visual inspection of the baggage bay discharge PBA 
switch for proper installation and a functional operation test. 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

    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 
and service information referenced above. The FAA is issuing this NPRM 
after determining that the unsafe condition described previously is 
likely to exist or develop on other products of the same type design.

Proposed AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified 
in the service information already described.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 42 airplanes of U.S. registry. The FAA

[[Page 21445]]

estimates the following costs to comply with this proposed AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
2 work-hours x $85 per hour = $170...........................              $0             $170           $7,140
----------------------------------------------------------------------------------------------------------------

    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, some or all of the costs of 
this proposed AD may be covered under warranty, thereby reducing the 
cost impact on affected operators.

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 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) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

List of Subjects in 14 CFR Part 39
