SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would apply to B-N Group Ltd. Models BN-2,
BN-2A, BN-2A-2, BN-2A-3, BN-2A-6, BN-2A-8, BN-2A-9, BN-2A-20, BN-2A-21,
BN-2A-26, BN-2A-27, BN-2B-20, BN-2B-21, BN-2B-26, BN-2B-27, BN2A MK.
III, BN2A MK. III-2, and BN2A MK. III-3 airplanes. That NPRM was
published in the Federal Register on October 30, 2013 (78 FR 64894).
That NPRM proposed to correct an unsafe condition for the specified
products. The MCAI states:
Britten-Norman Aircraft Limited has been made aware of two
occurrences where a failure of engine control cable assemblies has
caused engine control difficulties. In both reported cases, the
cable sliding end assemblies were in poor condition and in both
cases, an incorrect end-fitting was installed which may have
contributed to the failures.
This condition, if not detected and corrected, could result in
reduced engine control, possibly resulting in reduced control of the
aeroplane.
To address this potential unsafe condition, Britten-Norman
Aircraft have issued Service Bulletin (SB) 334 to provide inspection
instructions.
For the reason described above, this AD requires a one-time
inspection and functional test of the engine control cables and,
depending on findings, replacement of the cables.
The MCAI can be found in the AD docket on the Internet at: <a href="http://www.regulations.gov/#!documentDetail">http://www.regulations.gov/#!documentDetail</a>;D=FAA-2013-0924-0002.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (78 FR 64894, October 30,
2013) or on the determination of the cost to the public.
Conclusion
We reviewed the relevant data and determined that air safety and
the public interest require adopting the AD as proposed except for
minor editorial changes. We have determined that these minor changes:
<bullet> Are consistent with the intent that was proposed in the
NPRM (78 FR 64894, October 30, 2013) for correcting the unsafe
condition; and
<bullet> Do not add any additional burden upon the public than was
already proposed in the NPRM (78 FR 64894, October 30, 2013).
Costs of Compliance
We estimate that this AD will affect 101 products of U.S. registry.
We also estimate that it will take about 1 work-hour per product to
comply with the basic requirements of this AD. The average labor rate
is $85 per work-hour.
Based on these figures, we estimate the cost of the AD on U.S.
operators to be $8,585, or $85 per product.
In addition, we estimate that any necessary follow-on actions will
take about 10 work-hours and require parts costing $4,800 (4 per
airplane), for a cost of $5,650 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 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.

You may examine the AD docket on the Internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a> by searching for and locating it in Docket No. FAA-
2013-0924; or in person at the Docket Management Facility between 9
a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD
docket contains the NPRM, the regulatory evaluation, any comments
received, and other information. The street address for the Docket
Office (telephone (800) 647-5527) is in the ADDRESSES section. Comments

BN2A MK. III-3 airplanes, all serial numbers, certificated in any
category.
(d) Subject
Air Transport Association of America (ATA) Code 76: Engine
Controls.
(e) Reason
This AD was prompted by mandatory continuing airworthiness
information (MCAI) originated by an aviation authority of another
country to identify and correct an unsafe condition on an aviation
product. The MCAI describes the unsafe condition as damage of the
cable sliding end assembly and installation of the incorrect end
fitting on engine control cable assemblies. We are issuing this AD
to detect and correct damage of the cable sliding end assembly
(cracking, distortion, corrosion) and incorrect end fittings on the
engine control assemblies, which could lead to reduced engine
control with consequent loss of control.
(f) Actions and Compliance
Unless already done, do the following actions in paragraphs
(f)(1) through (f)(4) of this AD:
(1) Within the next 6 months after April 1, 2014 (the effective
date of this AD), do a one-time inspection of the engine control
cable assemblies, part number (P/N) 137835, P/N 172449-1, P/N 17250,
and P/N 172451, and surrounding areas for damage (cracking,
distortion, corrosion) and correct cable end-fitting and to assure
the wire locking is intact following Britten-Norman Aircraft Limited
Service Bulletin No. SB 334, Issue 1, dated August 30, 2013.
(2) If no discrepancies are found during the inspection required
in paragraph (f)(1) of this AD, inspect the control linkages for
proper adjustment and, before further flight, make any necessary
changes following Britten-Norman Aircraft Limited Service Bulletin
No. SB 334, Issue 1, dated August 30, 2013.
(3) If any discrepancies are found during the inspection
required in paragraph (f)(1) of this AD and/or the control linkages
cannot be properly adjusted as specified in paragraph (f)(2) of this
AD, before further flight, replace the engine control cable assembly
with a serviceable unit following Britten-Norman Aircraft Limited
Service Bulletin No. SB 334, Issue 1, dated August 30, 2013.
(4) After April 1, 2014 (the effective date of this AD), do not
install on any airplane engine control cable assemblies, part number
(P/N) 137835, P/N 172449-1, P/N 17250, and P/N 172451, unless they
are new or have been inspected as required in paragraphs (f)(1) and
(f)(2) of this AD and found free of any discrepancies and have
proper adjustment.
(g) Other FAA AD Provisions
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager,
Standards Office, FAA, has the authority to approve AMOCs for this
AD, if requested using the procedures found in 14 CFR 39.19. Send
information to ATTN: Taylor Martin, Aerospace Engineer, FAA, Small
Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri
64106; telephone: (816) 329-4138; fax: (816) 329-4090; email:

airplane to which the AMOC applies, notify your appropriate
principal inspector (PI) in the FAA Flight Standards District Office
(FSDO), or lacking a PI, your local FSDO.
(2) Airworthy Product: For any requirement in this AD to obtain
corrective actions from a manufacturer or other source, use these
actions if they are FAA-approved. Corrective actions are considered
FAA-approved if they are approved by the State of Design Authority
(or their delegated agent). You are required to assure the product
is airworthy before it is returned to service.
