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 supersede Airworthiness Directive (AD) AD 2018-
04-09 for 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 correct an unsafe condition on an aviation product. The 
MCAI describes the unsafe condition as incorrectly marked and 
annunciated low oil-pressure indication warnings. We are issuing this 
proposed AD to require actions to address the unsafe condition on these 
products.

Discussion

    We issued AD 2018-04-09, Amendment 39-19205 (83 FR 9793, March 8, 
2018) (``AD 2018-04-09'') to address an unsafe condition on Pacific 
Aerospace Limited Model 750XL airplanes. AD 2018-04-09 was based on 
mandatory continuing airworthiness information (MCAI) originated by the 
Civil Aviation Authority (CAA), which is the aviation authority for New 
Zealand.
    Since we issued AD 2018-04-09, Pacific Aerospace Limited has 
revised the airplane flight manual (AFM) (pilot's operating handbook). 
The CAA revised its previous MCAI and issued CAA AD DCA/750XL/19A, 
dated April 26, 2018 (referred to after this as ``the MCAI''), to 
mandate the AFM revisions and also to include an option to modify the 
oil pressure/temperature indicator. The MCAI states:

    DCA/750XL/19A revised to introduce revision 30 March 2018 for 
PAL 750XL POH AIR3237, and clarify the AD requirements.

    We are proposing this AD to retain the replacement of the pressure 
switch for the low oil pressure light and the oil pressure/temperature 
indicator. We are also proposing to require the revised AFM provisions 
and to clarify that you may modify the oil pressure/temperature 
indicator instead of replacing the indicator.
    You may examine the MCAI on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2018-
0842.

Related Service Information Under 1 CFR Part 51

    We reviewed Pacific Aerospace Temporary Revision Instruction 
Letter, dated October 2017, which includes Pacific Aerospace Temporary 
Revisions XL/POH/00/001, XL/POH/02/001, and XL/POH/03/001; and Pacific 
Aerospace Revision Instruction Letter, dated March 2018, which includes 
Pacific Aerospace POH AIR 3237 Revision, dated March 30, 2018, for 
750XL airplanes. For the applicable configurations, the service 
information includes revisions to the AFM that corrects the incorrect 
instrument markings.
    We also reviewed Pacific Aerospace Mandatory Service Bulletin 
PACSB/XL/088, dated August 11, 2017, which was previously approved for 
incorporation by reference on April 12, 2018 (83 FR 9793, March 8, 
2018), and describes procedures for replacement or modification of the 
low oil-pressure light, pressure switch, and indicator. 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 of the AD.

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

[[Page 53410]]

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 2 work-hours 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 $500 per product.
    Based on these figures, we estimate the cost of the proposed AD on 
U.S. operators to be $14,740, or $670 per product.
    Since the proposed AD requires the same actions as AD 2018-04-09, 
the costs of compliance remains the same and does not impose any 
additional costs on U.S. 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.
    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.

2. The FAA amends Sec.  39.13 by removing Amendment 39-19205 (83 FR 
9793, March 8, 2018), and adding the following new airworthiness 
directive (AD):

Pacific Aerospace Limited: Docket No. FAA-2018-0842; Product 
Identifier 2018-CE-025-AD.

(a) Comments Due Date

    We must receive comments by December 7, 2018.

(b) Affected ADs

    This AD replaces AD 2018-04-09, Amendment 39-19205 (83 FR 9793, 
March 8, 2018) (``AD 2018-04-09'').
