DEPARTMENT OF TRANSPORTATION

Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2019-0566; Product Identifier 2018-CE-035-AD; Amendment 
39-21182; AD 2020-15-19]
RIN 2120-AA64


Airworthiness Directives; Pacific Aerospace Limited Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
Pacific Aerospace Limited Model 750XL airplanes. This AD results from 
mandatory continuing airworthiness information (MCAI) issued 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 ineffective firewall sealing for firewall wiring 
penetrations. The FAA is issuing this AD to require actions to address 
the unsafe condition on these products.

DATES: This AD is effective August 19, 2020.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of August 19, 
2020.

ADDRESSES: For service information identified in this AD, contact 
Pacific Aerospace Limited, Airport Road, Hamilton, Private Bag 3027, 
Hamilton 3240, New Zealand; phone: +64 7843 6144; fax: +64 843 6134; 
email: [email protected]; internet: www.aerospace.co.nz. You may

SUPPLEMENTARY INFORMATION:

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to Pacific Aerospace 
Limited Model 750XL airplanes. The NPRM was published in the Federal 
Register on August 6, 2019 (84 FR 38146). The NPRM proposed to correct 
an unsafe condition of the specified products and was prompted by MCAI 
AD DCA/750XL/31, dated July 5, 2018, issued by the Civil Aviation 
Authority (CAA) of New Zealand. The MCAI states:

    During a review of the installation of the aircraft main loom 
[part number] P/N 11-81021, possible ineffective sealing was 
identified for firewall wiring penetrations. DCA/750XL/31 is issued 
to mandate the instructions in Pacific Aerospace Mandatory Service 
Bulletin (MSB) PACSB/XL/101 issue 1, dated 9 May 2018, or later 
approved revision to improve the firewall sealing by installing new 
components (firewall penetration tubes, firesleeve and hose clips).

    The CAA advised the design is non-compliant with regard to the 
fireproof requirements for firewalls. Ineffective sealant may fail to 
prevent fire propagation through the firewall, which could result in 
smoke or fire in the cockpit. The CAA issued the MCAI to correct this 
unsafe condition.
    You may examine the MCAI on the internet at: https://www.regulations.gov by searching for FAA-2019-0566-0002.

Comments

    The FAA gave the public the opportunity to participate in 
developing this AD. The FAA received no comments on the NPRM or on the 
determination of the cost to the public.

Conclusion

    The FAA reviewed the relevant data and determined that air safety 
and the public interest require adopting the AD as proposed.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Pacific Aerospace Mandatory Service Bulletin 
PACSB/XL/101, Issue 1, dated May 9, 2018. The service information 
provides instructions for installing improved firewall sealing for 
wiring penetration looms and correcting any damaged or chafed looms. 
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 will affect 22 products of U.S. 
registry. The FAA also estimates that it will take about 8 work-hours 
per product to comply with the basic requirements of this AD. The 
average labor rate is $85 per work-hour. Required parts will cost about 
$385 per product.
    Based on these figures, the FAA estimates the cost of this AD on 
U.S. operators to be $23,430, or $1,065 per product.
    According to the manufacturer, some 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 costs in our 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:

[[Page 45762]]

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 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.

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2020-15-19 Pacific Aerospace Limited: Amendment 39-21182; Docket No. 
FAA-2019-0566; Product Identifier 2018-CE-035-AD.

(a) Effective Date

    This AD becomes effective August 19, 2020.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Pacific Aerospace Limited Model 750XL 
airplanes, serial numbers up to and including 221, certificated in 
any category.

(d) Subject

    Air Transport Association of America (ATA) Code 71: Power Plant.

(e) Reason

    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 FAA is issuing this AD to prevent fire propagation 
through the firewall because of ineffective sealant, which could 
result in smoke or fire in the cockpit.

(f) Actions and Compliance

    Unless already done, within 3 months after August 19, 2020 (the 
effective date of this AD) or within 300 hours time-in-service after 
August 19, 2020 (the effective date of this AD), whichever occurs 
first, install new sealant components into the main loom firewall 
penetration hole and the ADAS or DAAM firewall penetration holes if 
installed by following the Accomplishment Instructions in Pacific 
Aerospace Mandatory Service Bulletin PACSB/XL/101, Issue 1, dated 
May 9, 2018, except you are not required to contact Pacific 
Aerospace Limited if there is any chafing or damage on a loom. 
Instead, your repair must be accomplished before further flight 
using a method approved by the Manager, Small Airplane Standards 
Branch, FAA, using the contact information in paragraph (g) of this 
AD, or approved by the Civil Aviation Authority (CAA) of New 
Zealand. For a repair method to be approved as required by this 
paragraph, the FAA or CAA approval letter must specifically refer to 
this AD.

(g) Alternative Methods of Compliance (AMOCs)

    The Manager, Small Airplane Standards Branch, FAA, has the 
authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19. Send information to ATTN: Mike 
Kiesov, Aerospace Engineer, FAA, Small Airplane Standards Branch, 
901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 
329-4144; fax: (816) 329-4090; email: [email protected]. Before 
using any approved AMOC on any airplane to which the AMOC applies, 
notify your appropriate principal inspector (PI) in the FAA Flight 
Standards District Office (FSDO), or lacking a PI, your local FSDO.
