Airworthiness Directives; Pacific Aerospace Limited Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Pacific Aerospace Limited Model 750XL airplanes. This AD results from 
mandatory continuing airworthiness information (MCAI) issued by the 
aviation authority of another country to identify and correct an unsafe 
condition on an aviation product. The MCAI describes the unsafe 
condition as insufficient engagement of the couplings with the flex 
drive of the rudder trim drive system. We are issuing this AD to 
require actions to address the unsafe condition on these products.

SUPPLEMENTARY INFORMATION:

Discussion

    The Civil Aviation Authority (CAA), which is the aviation authority 
for New Zealand, has issued CAA AD DCA/750XL/26, dated February 28, 
2018 (referred to after this as ``the MCAI''), to correct an unsafe 
condition for Pacific Aerospace Limited Model 750XL airplanes. The MCAI 
states:

    This [CAA] AD mandates the instructions in Pacific Aerospace 
Limited Mandatory Service Bulletin (MSB) PACSB/XL/085 issue 1, dated 
8 January 2018. The MSB is issued to prevent disengagement of the 
rudder and/or elevator trim drive due to possible insufficient 
engagement of the couplings with the flex drive at fuselage stations 
115.34 and 180.85, which could result in an ineffective rudder and/
or elevator trim system.

You may examine the MCAI on the internet at http://www.regulations.gov 
by searching for and locating Docket No. FAA-2018-0285.

Related Service Information Under 1 CFR Part 51

    Pacific Aerospace Limited has issued Pacific Aerospace Mandatory 
Service Bulletin PACSB/XL/085, Issue 1, dated January 8, 2018. The 
service information describes procedures for removal of the rudder and 
elevator drive shaft couplings and replacement with new couplings to 
ensure proper engagement of the drive ends. 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 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 issuing this AD because we 
evaluated all information provided by the State of Design Authority and 
determined the unsafe condition exists and is likely to exist or 
develop on other products of the same type design.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because if 
the rudder and/or elevator trim drive couplings become disconnected and 
the rudder and elevator trim systems will become inoperable, which 
increases the workload for the pilot. Therefore, we find good cause 
that notice and opportunity for prior public comment are impracticable. 
In addition, for the reason stated above, we find that good cause 
exists for making this amendment effective in less than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2018-0285; Directorate 
Identifier 2018-CE-010-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD because of 
those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    We estimate that this AD will affect 22 products of U.S. registry. 
We also estimate that it would take about 6 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Required parts would cost about $400 per product.
    Based on these figures, we estimate the cost of the AD on U.S. 
operators to be $20,020, or $910 per product.

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 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:

[[Page 15045]]

    (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.

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

2018-07-14 Pacific Aerospace Limited: Amendment 39-19245; Docket No. 
FAA-2018-0285; Directorate Identifier 2018-CE-010-AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective April 30, 
2018.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to the following Pacific Aerospace Limited Model 
750XL airplanes, certificated in any category:
    (1) All serial numbers equipped with modification PAC/XL/0582;
