39-19188; AD 2018-03-15]
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
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 abrasion damage of components or wiring behind the
instrument panel. We are issuing this AD to require actions to address
the unsafe condition on these products.
DATES: This AD is effective March 5, 2018.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of March 5,
We must receive comments on this AD by March 30, 2018.
ADDRESSES: You may send comments by any of the following methods:

The Civil Aviation Authority, which is the aviation authority for
New Zealand, has issued CAA AD DCA/750XL/22, dated December 19, 2017
(referred to after this as ``the MCAI''), to correct an unsafe
condition for Pacific Aerospace Limited Model 750XL airplanes. To
accompany that MCAI, the CAA issued Notification of Airworthiness
Directive issued for New Zealand Aeronautical Products IAW ICAO Annex
8, dated December 19, 2017; the Notification states:
This [CAA] AD with effective date 28 December 2017 mandates an
inspection of components and wiring behind the instrument panel for
possible abrasion damage caused by ventilation hose chafing per the
instructions in Pacific Aerospace Mandatory Service Bulletin (MSB)
PACSB/XL/083 issue 1, dated 15 December 2017, or later approved
The [CAA] AD is prompted by two reports of finding abrasion
damage behind the instrument panel caused by ventilation hose
In addition to the required inspection, this AD requires wrapping
the ventilation hose with anti-abrasion tape and rerouting the hose.
This AD also requires contacting the manufacturer for corrective action
if abrasion damage is found during the required inspection. You may
examine the MCAI on the internet at http://www.regulations.gov by
searching for and locating Docket No. FAA-2018-0067.
Related Service Information Under 1 CFR Part 51
Pacific Aerospace Limited has issued Pacific Aerospace Mandatory
Service Bulletin PACSB/XL/083, Issue 1, dated December 15, 2017. The
service information describes procedures for inspection of the
ventilation hose behind the instrument panel, wrapping the ventilation
hose with anti-abrasion tape, and rerouting the hose. 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
chafing of the ventilation hose on instrument components and wiring
could cause abrasion damage and lead to short circuit, smoke, and/or
fire. Therefore, we determined that notice and opportunity for public
comment before issuing this AD are impracticable and that good cause
exists for making this amendment effective in fewer than 30 days.
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-2018-0067; Directorate
Identifier 2017-CE-048-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
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 3 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 $90 per product.
Based on these figures, we estimate the cost of the AD on U.S.
operators to be $7,590, or $345 per product.
The extent of abrasion damage could vary from airplane to airplane.
We have no way of knowing how many airplanes may have abrasion damage
or the extent of that damage; therefore, we have no way of determining
an estimated cost for repair.
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
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
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:
(1) Is not a ``significant regulatory action'' under Executive
(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.
