the unsafe condition as failure of a brake master cylinder pivot pin.
We are issuing this AD to require actions to address the unsafe
condition on these products.

SUPPLEMENTARY INFORMATION:

Discussion

The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued AD
No.: 2015-0065-E, dated April 24, 2015, to correct an unsafe condition
for the specified products. The MCAI states:

An occurrence was reported where pivot pin Part Number (P/N)
T67M-45-539, of rudder pedal assembly #4, installed on the right
hand (RH) side of the aeroplane (RH seat, RH pedal) failed during
taxi. This caused the rudder pedal mechanism to detach from the
brake master cylinder.

This condition, if not detected and corrected, could cause the
rudder linkages to rotate out of their normal orientation, possibly
resulting in jammed rudder controls and consequent loss of control
of the aeroplane.

To address this potential unsafe condition, Slingsby Advanced
Composites Ltd, trading as Marshall Aerospace and Defence Group
(hereafter called `Marshall' in this AD) issued Service Bulletin
(SB) SBM200 to provide inspection instructions.

For the reason described above, this AD requires repetitive
inspections of the brake master cylinder pivot pins of rudder pedal
assemblies #1 and #4 and, depending on findings, replacement of the
affected pivot pins(s).

You may examine the MCAI on the Internet at http://www.regulations.gov
by searching for and locating Docket No. FAA-2015-1737.

Relevant Service Information Under 1 CFR Part 51

Marshall Aerospace and Defence Group Service Bulletin SBM 200,
Revision 1, dated April 2015. The transmittal letter for Marshall
Aerospace and Defence Group SBM 200, Revision 1, incorrectly states it
transmits the Initial Issue; page 1 of this service bulletin is dated
April 2015; pages 2 through 8 are dated March 2015. The actions
described in this service information are intended to correct the
unsafe condition identified in the MCAI. The service bulletin describes
procedures for inspecting the brake master cylinder pivot pins, part
number (P/N) T67M-45-539, that are installed on rudder pedal assemblies
#1 and #4 for cracks and distortion and replacing any damaged pivot
pins. 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 this
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
failure of a brake master cylinder pivot pin could cause the rudder
pedal mechanism to detach from the brake master cylinder, which could
result in jammed rudder controls and consequent loss of control.
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-2015-1737; Directorate
Identifier 2015-CE-014-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 2 products of U.S. registry.
We also estimate that it will 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 $50 per product.

Based on these figures, we estimate the cost of the AD on U.S.
operators to be $1,120, or $560 per product.

In addition, we estimate that any necessary follow-on actions will
take about .5 work-hours and require parts costing $100, for a cost of
$142.50 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.

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.
