14 CFR Part 39

[Docket No. FAA-2018-0286; Product Identifier 2018-CE-008-AD; Amendment 
39-19340; AD 2018-15-08]
RIN 2120-AA64


Airworthiness Directives; Pacific Aerospace Limited Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are 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 airplane sound insulation materials attached to the aft 
face of the firewall not complying with the applicable burn testing 
criteria for materials on the cabin side of the firewall. We are 
issuing this AD to require actions to address the unsafe condition on 
these products.

DATES: This AD is effective August 31, 2018.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of August 31, 
2018.

ADDRESSES: You may examine the AD docket on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2018-

SUPPLEMENTARY INFORMATION:

Discussion

    We 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 April 11, 2018 (83 FR 15517). The NPRM proposed to correct an unsafe 
condition for the specified products and was based on mandatory 
continuing airworthiness information (MCAI) originated by an aviation 
authority of another country. The MCAI states:

    The sound insulation material on the aft face of the firewall 
must comply with the applicable burn test criteria specified in FAR 
[14 CFR] 23.853(f). [As of August 30, 2017, Sec.  23.853 was 
replaced by Sec.  23.2325 (81 FR 96572, December 30, 2016).]
    Inspect the aft face of the firewall and determine if sound 
insulation material is installed per the instructions in Pacific 
Aerospace Mandatory Service Bulletin (MSB) PACSB/XL/095 issue 1, 
dated 21 December 2017, or later approved revision.
    If a layer of black foam insulating material is found covering 
the firewall, then remove the material per the instructions in MSB 
PACSB/XL/095 before further flight.

    The MCAI can be found in the AD docket on the internet at: https://www.regulations.gov/document?D=FAA-2018-0286-0002.

Comments

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

Conclusion

    We 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

    We reviewed Pacific Aerospace Service Bulletin PACSB/XL/095, Issue 
1, dated December 21, 2017. The service information describes 
procedures for inspection of the airplane sound insulation attached to 
the aft face of the firewall and removal 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 the ADDRESSES section.

Costs of Compliance

    We estimate that this AD will affect 22 products of U.S. registry. 
We also estimate that it would take about 1 work-hour per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour.
    Based on these figures, we estimate the cost of this AD on U.S. 
operators to be $1,870, or $85 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 8 work-hours, for a cost of $680 per product. We have no way 
of determining the number of products that may need these actions.

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.
    We are 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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C.

[[Page 35539]]

In accordance with that order, issuance of ADs is normally a function 
of the Compliance and Airworthiness Division, but during this 
transition period, the Executive Director has delegated the authority 
to issue ADs applicable to small airplanes, gliders, balloons, 
airships, domestic business jet transport airplanes, and associated 
appliances to the Director of the Policy and Innovation Division.

Regulatory Findings

    We determined that 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) Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) 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.

    You may examine the AD docket on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2018-
0286; or in person at Docket Operations between 9 a.m. and 5 p.m.,
