SUPPLEMENTARY INFORMATION:
Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union, has issued EASA AD
2018-0103, dated April 30, 2018 (referred to after this as the
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to
correct an unsafe condition for all Saab AB, Saab Aeronautics Model
SAAB 2000 airplanes. The MCAI states:
A manufacturing defect was identified on certain aileron
bellcrank support brackets, installed on the outboard section of the
left hand (LH) and right hand (RH) wing. The material thickness of
the lugs attaching the support bracket to the rear spar of the wing
was found to be insufficient.
This condition, if not detected and corrected, could, in case of
an aileron jamming, lead to support bracket failure, possibly
resulting in reduced control of the aeroplane.
To address this potential unsafe condition, SAAB issued the SB
[Saab Service Bulletin 2000-27-056, dated April 18, 2018] to provide
instructions for inspection and replacement of affected support
brackets.
For the reason described above, this [EASA] AD requires a one-
time inspection of all support brackets to determine the thickness
and, depending on findings, repetitive inspections of the affected
support brackets. This [EASA] AD also requires reporting the
measured thickness, and replacement of all affected support brackets
with serviceable support brackets, which constitutes terminating
action.
You may examine the MCAI on the internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a> by searching for and locating Docket No. FAA-2018-
0450.
Related Service Information Under 1 CFR Part 51
Saab AB, Saab Aeronautics has issued Saab Service Bulletin 2000-27-
056, dated April 18, 2018. The service information describes procedures
for a detailed visual inspection for cracks, corrosion, and damage
(including missing paint) of the affected lug and the adjacent area of
the installed aileron bellcrank support brackets on the left hand and
right hand wing; a thickness measurement of the affected lug attaching
the support bracket to the rear spar of the wing, and replacement of
aileron bellcrank support brackets. 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 This 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 the State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information referenced above. We are issuing this AD because we
evaluated all pertinent information and determined the unsafe condition
exists and is likely to exist or develop on other products of the same
type design.
Difference Between This AD and the MCAI
The MCAI requires replacing all affected support brackets. However,
the planned compliance time for the replacement would allow enough time
to provide notice and opportunity for prior public comment on the
merits of the replacement. Therefore, we are considering a notice of
proposed rulemaking (NPRM) requiring this replacement, which would
terminate the repetitive inspections required by this AD.
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 the
material thickness of the affected lug attaching the aileron bellcrank
support bracket to the rear spar of the wing have been found to be
insufficient, which, in the event of an aileron jam, could lead to
support bracket failure and possible reduced control of the airplane.
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.
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-2018-0450; Product
Identifier 2018-NM-073-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 based on
those comments.
[[Page 24401]]
We will post all comments we receive, without change, to <a href="http://www.regulations.gov">http://www.regulations.gov</a>, 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 affects 8 airplanes of U.S. registry. We
estimate the following costs to comply with this AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
3 work-hours x $85 per hour = $255.............................. $0 $255 $2,040
----------------------------------------------------------------------------------------------------------------
We estimate the following costs to do any necessary on-condition
actions that would be required based on the results of any required
actions. We have no way of determining the number of aircraft that
might need these on-condition actions:
Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
Labor cost Parts cost Cost per product
------------------------------------------------------------------------
Up to 16 work-hours x $85 per Up to $18,074..... Up to $19,434.
hour = $1,360.
------------------------------------------------------------------------
We estimate that it would take about 1 work-hour per product to
comply with the reporting requirement in this AD. The average labor
rate is $85 per hour. Based on these figures, we estimate the cost of
reporting the inspection results on U.S. operators to be $85 per
product.
Paperwork Reduction Act
A federal agency may not conduct or sponsor, and a person is not
required to respond to, nor shall a person be subject to penalty for
failure to comply with a collection of information subject to the
requirements of the Paperwork Reduction Act unless that collection of
information displays a current valid OMB control number. The control
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in
the Costs of Compliance section of this document and includes time for
reviewing instructions, as well as completing and reviewing the
collection of information. Therefore, all reporting associated with
this AD is mandatory. Comments concerning the accuracy of this burden
and suggestions for reducing the burden should be directed to the FAA
at 800 Independence Ave. SW, Washington, DC 20591, ATTN: Information
Collection Clearance Officer, AES-200.
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 transport category airplanes to
the Director of the System Oversight 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:
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.
