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.

[[Page 30137]]

    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.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 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.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new AD:

2015-11-01 Slingsby Aviation Ltd.: Amendment 39-18164; Docket No. 
FAA-2015-1737; Directorate Identifier 2015-CE-014-AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective June 16, 
2015.

(b) Affected ADs

    None.

[[Page 30138]]

(c) Applicability

    This AD applies to Slingsby Aviation Ltd. Models T67M260 and 
T67M260-T3A airplanes, all serial numbers, certificated in any 
category.

(d) Subject

    Air Transport Association of America (ATA) Code 27: Flight 
Controls.

(e) Reason

    This AD was prompted by 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 failure of a 
brake master cylinder pivot pin. We are issuing this AD to prevent 
failure of a brake master cylinder pivot pin, which could cause the 
rudder pedal mechanism to detach from the brake master cylinder. 
This failure could result in jammed rudder controls and consequent 
loss of control.

 (f) Actions and Compliance

    Unless already done, do the actions in paragraphs (f)(1) and 
(f)(2) of this AD.
    (1) Before further flight after June 16, 2015 (the effective 
date of this AD) and repetitively thereafter every 300 hours time-
in-service or 12 months, whichever occurs first, inspect the brake 
master cylinder pivot pins, part number T67M-45-539, installed on 
rudder pedal assemblies #1 and #4. Do the inspections following the 
Accomplishment Instructions in Marshall Aerospace and Defence Group 
Service Bulletin SBM 200, Revision 1, dated April 2015. This AD does 
not require the retention and reporting requirements of paragraph 
(2) of F. COMPLETION in the Accomplishment Instructions of this 
service bulletin.
    (2) If, during any inspection required in paragraph (f)(1) of 
this AD, any crack or distortion to a brake master cylinder pivot 
pin is found, or a pivot pin fails the dimensional check, before 
further flight, replace the affected pivot pin with a serviceable 
part. Do the replacement as specified in paragraph C.(1)(j) of the 
Inspection section of the Accomplishment Instructions in Marshall 
Aerospace and Defence Group Service Bulletin SBM 200, Revision 1, 
dated April 2015. After doing this replacement, continue with the 
repetitive inspection requirement in paragraph (f)(1) of this AD.

(g) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager,
