Airworthiness Directives; B-N Group Ltd. Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 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 would supersede AD 2014-03-18. This proposed AD results 
from 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 proposed AD to require actions to address the unsafe 
condition on these products.

DATES: We must receive comments on this proposed AD by December 14, 
2015.

Discussion

    On February 6, 2014, we issued AD 2014-03-18, Amendment 39-17755 
(79 FR 10340; February 25, 2014). That AD required actions intended to 
address an unsafe condition on B-N Group Ltd. 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 and was based on mandatory continuing 
airworthiness information (MCAI) originated by an aviation authority of 
another country.
    Since we issued AD 2014-03-18, it was found that the service 
information did not correctly identify the parts to be inspected on the 
Trislander (BN2A MK III) series airplanes. The service information has 
been revised to correctly identify the parts to be inspected on those 
airplanes.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued AD 
No.: 2015-0184, dated September 1, 2015 (referred to after this as 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    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.

    You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2015-
4803.

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 NPRM.

FAA's Determination and Requirements of the Proposed 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 proposing this AD because 
we evaluated all information and determined the unsafe condition exists 
and is likely to exist or develop on other products of the same type 
design.

Costs of Compliance

    We estimate that this proposed 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 the proposed 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

[[Page 66484]]

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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 proposed 
regulation:
    (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.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 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 removing Amendment 39-17755 (79 FR 
10340; February 25, 2014), and adding the following new AD:

B-N Group Ltd.: Docket No. FAA-2015-4803; Directorate Identifier 
2015-CE-034-AD.

(a) Comments Due Date

    We must receive comments by December 14, 2015.

(b) Affected ADs

    This AD supersedes AD 2014-03-18, Amendment 39-17755 (79 FR 
10340; February 25, 2014).

(c) Applicability

    This AD applies 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,

(e) Reason

    This AD was prompted by 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.
