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 <a href="https://www.regulations.gov">https://www.regulations.gov</a> 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,
(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.
