Download as PDF lotter on DSK11XQN23PROD with RULES1 Federal Register / Vol. 86, No. 232 / Tuesday, December 7, 2021 / Rules and Regulations by the benefits derived by the operation of the Order. The Committee’s meeting was widely publicized throughout the Florida avocado industry and all interested persons were invited to attend the meeting and participate in Committee deliberations on all issues. Like all Committee meetings, the April 14, 2021, meeting was a public meeting, and all entities, both large and small, were able to express views on this issue. 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. 0581–0189 Fruit Crops. No changes in those requirements are necessary as a result of this action. Should any changes become necessary, they would be submitted to OMB for approval. This rule imposes no additional reporting or recordkeeping requirements on either small or large Florida avocado 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. As noted in the initial regulatory flexibility analysis, USDA has not identified any relevant Federal rules that duplicate, overlap, or conflict with this rule. 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. A proposed rule concerning this action was published in the Federal Register on August 24, 2021 (86 FR 47248). Copies of the proposed rule were also mailed or sent via email to all Florida avocado handlers. The proposal was made available through the internet by USDA and the Office of the Federal Register. A 30-day comment period ending September 23, 2021, was provided for interested persons to respond to the proposal. During the comment period, one comment was received in response to the proposal. The comment received did not address the merits of this rule. Accordingly, no changes will be made to the rule as proposed, based on the comment received. 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/ moa/small-businesses. Any questions about the compliance guide should be VerDate Sep<11>2014 16:02 Dec 06, 2021 Jkt 256001 sent to Richard Lower at the previously mentioned address in the FOR FURTHER INFORMATION CONTACT section.

SUPPLEMENTARY INFORMATION: Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain serial-numbered Pacific Aerospace Limited Model 750XL airplanes fitted with an air conditioner and/or standby alternator. The NPRM published in the Federal Register on August 27, 2021 (86 FR 48086). The NPRM was prompted by MCAI originated by the Civil Aviation Authority (CAA), which is the aviation E:\FR\FM\07DER1.SGM 07DER1 69162 Federal Register / Vol. 86, No. 232 / Tuesday, December 7, 2021 / Rules and Regulations authority for New Zealand. The CAA of New Zealand has issued AD DCA/ 750XL/37, effective April 25, 2019 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for certain Pacific Aerospace Limited Model 750XL airplanes. The MCAI states: DCA/750XL/37 is prompted by a review of the installation of the engine fuel lines and the electrical installation forward of the engine firewall on aircraft fitted with an air conditioner and/or a standby alternator, including those aircraft configured for the installation of an air conditioner and/or a standby alternator. It was found that the engine fuel feed lines hoses could possibly chafe against the adjacent electrical wiring and the ignition exciter, which could result in a fuel leak and possible fire. The [CAA] AD is issued to introduce the corrective actions in Pacific Aerospace Mandatory Service Bulletin (MSB) PACSB/XL/113 issue 2, dated 8 March 2019. You may examine the MCAI in the AD docket at https:// www.regulations.gov by searching for and locating Docket No. FAA–2021– 0711. Discussion of Final Airworthiness Directive Comments The FAA received a comment from an individual who supported the NPRM without change. Conclusion 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 reviewed the relevant data, considered any comments received, and determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on these products. This AD is adopted as proposed in the NPRM. lotter on DSK11XQN23PROD with RULES1 Related Service Information Under 1 CFR Part 51 The FAA reviewed Pacific Aerospace Mandatory Service Bulletin PACSB/XL/ 113, Issue 2, dated March 8, 2019. The service information contains procedures for inspecting the engine fuel feed line hoses and the electrical wiring for chafing or damage, rerouting all fuel lines and the fuel transducer and pressure switch wiring (including installing P clips), and inspecting the fuel hose for chafing and replacing chafed fire sleeves or fuel hoses if necessary. This service information is VerDate Sep<11>2014 16:02 Dec 06, 2021 Jkt 256001 reasonably available because the interested parties have access to it through their normal course of business or by the means identified in ADDRESSES. 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. Differences Between This AD and the MCAI The MCAI requires an inspection at the next 150 hour maintenance inspection or within the next 50 hours time-in-service (TIS), whichever occurs later, while this AD requires those actions within 50 hours TIS or at the next annual inspection after the effective date of this AD, whichever occurs later. If there is no chafing and damage found during the inspection, the MCAI requires certain follow-on actions at the next 300 hour maintenance inspection or within the next 50 hours TIS, whichever is later. This AD requires those actions within 50 hours TIS or at the next annual inspection, whichever occurs later, because there is no regulatory requirement for operators in the U.S. to have 150-hour or 300-hour maintenance inspections. Regulatory Findings Costs of Compliance The FAA estimates that this AD affects 23 airplanes of U.S. registry. The FAA also estimates that it will take about 5 work-hours per airplane and require parts costing $20 per airplane to comply with the inspection and rerouting that are required by this AD. The average labor rate is $85 per workhour. Based on these figures, the FAA estimates the inspection and re-routing cost of this AD on U.S. operators to be $10,235, or $445 per airplane. The FAA has included all known costs in its cost estimate. According to the manufacturer, however, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected operators.

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to certain serial-numbered 
Pacific Aerospace Limited Model 750XL airplanes fitted with an air 
conditioner and/or standby alternator. The NPRM published in the 
Federal Register on August 27, 2021 (86 FR 48086). The NPRM was 
prompted by MCAI originated by the Civil Aviation Authority (CAA), 
which is the aviation

[[Page 69162]]

authority for New Zealand. The CAA of New Zealand has issued AD DCA/
750XL/37, effective April 25, 2019 (referred to after this as ``the 
MCAI''), to correct an unsafe condition for certain Pacific Aerospace 
Limited Model 750XL airplanes. The MCAI states:

    DCA/750XL/37 is prompted by a review of the installation of the 
engine fuel lines and the electrical installation forward of the 
engine firewall on aircraft fitted with an air conditioner and/or a 
standby alternator, including those aircraft configured for the 
installation of an air conditioner and/or a standby alternator. It 
was found that the engine fuel feed lines hoses could possibly chafe 
against the adjacent electrical wiring and the ignition exciter, 
which could result in a fuel leak and possible fire. The [CAA] AD is 
issued to introduce the corrective actions in Pacific Aerospace 
Mandatory Service Bulletin (MSB) PACSB/XL/113 issue 2, dated 8 March 
2019.

    You may examine the MCAI in the AD docket at https://www.regulations.gov by searching for and locating Docket No. FAA-2021-
0711.

Discussion of Final Airworthiness Directive

Comments

    The FAA received a comment from an individual who supported the 
NPRM without change.

Conclusion

    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 reviewed the relevant 
data, considered any comments received, and determined that air safety 
requires adopting this AD as proposed. Accordingly, the FAA is issuing 
this AD to address the unsafe condition on these products. This AD is 
adopted as proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Pacific Aerospace Mandatory Service Bulletin 
PACSB/XL/113, Issue 2, dated March 8, 2019. The service information 
contains procedures for inspecting the engine fuel feed line hoses and 
the electrical wiring for chafing or damage, rerouting all fuel lines 
and the fuel transducer and pressure switch wiring (including 
installing P clips), and inspecting the fuel hose for chafing and 
replacing chafed fire sleeves or fuel hoses if necessary. 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 ADDRESSES.

Differences Between This AD and the MCAI

    The MCAI requires an inspection at the next 150 hour maintenance 
inspection or within the next 50 hours time-in-service (TIS), whichever 
occurs later, while this AD requires those actions within 50 hours TIS 
or at the next annual inspection after the effective date of this AD, 
whichever occurs later. If there is no chafing and damage found during 
the inspection, the MCAI requires certain follow-on actions at the next 
300 hour maintenance inspection or within the next 50 hours TIS, 
whichever is later. This AD requires those actions within 50 hours TIS 
or at the next annual inspection, whichever occurs later, because there 
is no regulatory requirement for operators in the U.S. to have 150-hour 
or 300-hour maintenance inspections.

Costs of Compliance

    The FAA estimates that this AD affects 23 airplanes of U.S. 
registry. The FAA also estimates that it will take about 5 work-hours 
per airplane and require parts costing $20 per airplane to comply with 
the inspection and re-routing that are required by this AD. The average 
labor rate is $85 per work-hour.
    Based on these figures, the FAA estimates the inspection and re-
routing cost of this AD on U.S. operators to be $10,235, or $445 per 
airplane.
    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, some of the costs of this 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

    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,

 (d) Subject

    Joint Aircraft System Component (JASC) Code 2820, Aircraft Fuel 
Distribution, and 2497, Electrical Power System Wiring.

 (e) Unsafe Condition

    This AD was prompted by mandatory continuing airworthiness 
information (MCAI) originated by an aviation authority of another 
country to identify and correct an unsafe condition on an aviation 
product. The MCAI describes the unsafe condition as chafing of the 
engine fuel feed line hoses. The FAA is issuing this AD to prevent 
chafing of the engine fuel feed line hoses with electrical wiring 
and the ignition exciter located forward of the engine firewall. The 
unsafe condition, if not addressed, could result in a fuel leak and 
fire.

 (f) Compliance

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

 (g) Required Actions

    Within 50 hours time-in-service (TIS) or at the next annual 
inspection after the effective date of this AD, whichever occurs 
later, inspect the engine fuel feed line hoses and the electrical 
wiring for chafing and damage in accordance with the Accomplishment 
Instructions, Part A steps (3) and (4), in MSB PACSB/XL/113, Issue 
2.
    (1) If there is any chafing or damage that penetrates the orange 
outer covering of the fuel line fire sleeve or if there is any 
chafed or damaged electrical wiring, before further flight, inspect 
the fuel hose for chafing, replace any chafed fire sleeve or fuel 
hose, and reroute all fuel lines in accordance with the 
Accomplishment Instructions, Part B, in MSB PACSB/XL/113, Issue 2.
    (2) If there are no chafed or damaged engine fuel feed line 
hoses and no chafed or damaged electrical wiring, within 50 hours 
TIS or at the next annual inspection, whichever occurs later, 
reroute all fuel lines in accordance with the Accomplishment 
Instructions, Part B, in MSB PACSB/XL/113, Issue 2.
