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

[[Page 8144]]

BN2A MK. III-3 airplanes. The NPRM was published in the Federal 
Register on October 29, 2015 (80 FR 66482), and proposed to supersede 
AD 2014-03-18, Amendment 39-17755 (79 FR 10340; February 25, 2014).
    The NPRM proposed to correct an unsafe condition for the specified 
products and was based on mandatory continuing airworthiness 
information (MCAI) originated by an aviation authority of another 
country. The MCAI states that:

    Britten-Norman Aircraft Limited was 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 issued Service Bulletin (SB) 334 to provide inspection 
instructions, and EASA issued AD 2013-0215 to require a one-time 
inspection and functional test of the engine control cables and, 
depending on findings, replacement of the cables.
    Subsequently, as it was found that BN2 ``Islander'' aeroplanes 
were mistakenly omitted from the AD applicability, EASA issued AD 
2013-0263, retaining the requirements of EASA AD 2013-0215, which 
was superseded, and extending the applicability to BN2 aeroplanes.
    Since EASA AD 2013-0263 was issued, it was found that certain 
parts, specific to BN2A ``Trislander'' aeroplanes only, were 
inadvertently not included in SB 334 and, as a consequence, not 
required by AD 2013-0263 to be inspected.
    Prompted by these findings, Britten-Norman revised SB 334 (now 
at issue 2) to include the missing parts.
    For the reason described above, this AD retains the requirements 
of EASA AD 2013-0263, which is superseded, and adds inspection 
requirements for the additional parts.

The MCAI can be found in the AD docket on the Internet at:  http://www.regulations.gov/#!documentDetail;D=FAA-2015-4803-0001.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM 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:
     Are consistent with the intent that was proposed in the 
NPRM (80 FR 66482, October 29, 2015) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (80 FR 66482, October 29, 2015).

Related Service Information Under 1 CFR Part 51

    We reviewed Britten-Norman Aircraft Limited Service Bulletin No. SB 
334, Issue 1, dated August 30, 2013; and Britten-Norman Aircraft 
Limited Service Bulletin No. SB 334, Issue 2, dated July 17, 2015. The 
service information describes procedures for inspection and replacement 
if necessary of the engine control cable assemblies. 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 final rule.

Costs of Compliance

    We estimate that this AD will affect 96 products of U.S. registry. 
We also estimate that it would take about 1 work-hour per product to 
comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour.
    Based on these figures, we estimate the cost of this AD on U.S. 
operators to be $8,160 or $85 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 10 work-hours and require parts costing $6,000, for a cost 
of $6,850 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.

(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 possible damage 
of the cable sliding end assembly and installation of the incorrect 
end fitting on engine control cable assemblies. We are issuing this 
proposed 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, and to 
incorporate revised service information with updated information on 
applicability and on the identity of parts to be inspected on some 
airplanes.
