RIN 2120-AA64


Airworthiness Directives; Pacific Aerospace Limited Airplanes

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

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Pacific Aerospace Limited Model 750XL airplanes. This proposed 
AD results from mandatory continuing airworthiness information (MCAI) 
originated by an aviation authority of another country to identify and 
address an unsafe condition on an aviation product. The MCAI describes 
the unsafe condition as insufficient clearance between the pitot tubes 
and the primary support at the flame arrester intersection. We are 
issuing this proposed AD to require actions to address the unsafe 
condition on these products.

DATES: We must receive comments on this proposed AD by June 25, 2018.

Discussion

    The Civil Aviation Authority of New Zealand (CAA), has issued DCA/
750XL/24A, dated March 22, 2018 (referred to after this as ``the 
MCAI''), to correct an unsafe condition for Pacific Aerospace Limited 
Model 750XL airplanes. The MCAI states:

    Pacific Aerospace SB PACSB/XL/094 issue 2, dated 20 March 2018 
revised to include inspection information, and DCA/750XL/24A updated 
to introduce the revised SB.
    The [CAA] AD is prompted by a production inspection of installed 
pitot static plumbing which identified insufficient clearance 
between the pitot tubes and the primary support at the flame 
arrestor intersection.

    This proposed AD would require inspecting the pitot static tubes 
for chafing damage, replacing tubing as necessary, installing 
additional clamp for pitot static tube support, protecting plumbing 
with spiralwrap, and ensuring proper clearance between the pitot tubes 
and the primary support at the flame arrester intersection. You may 
examine the MCAI on the internet at http://www.regulations.gov by 
searching for and locating Docket No. FAA-2018-0371.

Related Service Information Under 1 CFR Part 51

    Pacific Aerospace Limited has issued Pacific Aerospace Service 
Bulletin PACSB/XL/094, Issue 2, dated March 20, 2018. The service 
information describes procedures for inspecting the pitot static tubing 
for chafing, replacing tubing as necessary, installing an additional 
clamp for pitot static tube support, protecting plumbing with 
spiralwrap, and ensuring proper clearance between the pitot tubes and 
the primary support at the flame arrester intersection. 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 and Requirements of the Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with this State of Design Authority, they 
have notified us of the unsafe condition described in the MCAI and 
service information referenced above. We are proposing this AD because 
we evaluated all information and determined the unsafe condition exists 
and is likely to exist or develop on other products of the same type 
design.

Costs of Compliance

    We estimate that this proposed 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 proposed AD. The 
average labor rate is $85 per work-hour. Required parts would cost 
about $25 per product.
    Based on these figures, we estimate the cost of the proposed AD on 
U.S. operators to be $2,420, or $110 per product.
    In addition, we estimate that any necessary follow-on actions would 
take

[[Page 21963]]

about 1 work-hour and require parts costing $25, for a cost of $110 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. 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 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) 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.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new AD:

Pacific Aerospace Limited: Docket No. FAA-2018-0371; Product 
Identifier 2018-CE-005-AD.

(a) Comments Due Date

    We must receive comments by June 25, 2018.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Pacific Aerospace Limited Model 750XL 
airplanes, all serial numbers up to and including XL200, 
certificated in any category.

(d) Subject

    Air Transport Association of America (ATA) Code 34: Navigation.

(e) Reason

    This AD was prompted by mandatory continuing airworthiness 
information (MCAI) originated by an aviation authority of another 
country to identify and address an unsafe condition on an aviation 
product. The MCAI describes the unsafe condition as insufficient 
clearance between the pitot tubes and the primary support at the 
flame arrester intersection. We are issuing this AD to prevent 
chafing between the pitot-static plumbing and the flame arrestor, 
which could lead to damage of the pitot-static lines.

(f) Actions and Compliance

    Unless already done, do the following actions in paragraphs 
(f)(1) through (3) of this AD following the Accomplishment 
Instructions in Pacific Aerospace Service Bulletin PACSB/XL/094, 
Issue 2, dated March 20, 2018.
    (1) Within the next 100 hours time-in-service (TIS) after the 
effective date of this AD or within the next 60 days after the 
effective date of this AD, whichever occurs first, inspect the pitot 
static tubing adjacent to the flame arrestor for chafing damage.
    (2) If any chafing damage is founding during the inspection 
required in paragraph (f)(1) of this AD, before further flight, 
repair or replace any damaged tubing and conduct a pitot and static 
leak check.
    (3) Within the next 100 hours TIS after the effective date of 
this AD or within the next 60 days after the effective date of this 
AD, whichever occurs first, install an additional support clamp, 
protect plumbing with spiralwrap, and ensure proper clearance 
between the pitot tubes and the primary support at the flame 
arrester intersection.

(g) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) 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,
