Ainvorthiness Directives; B-N Group Ltd. Airplanes 

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

ACTION: Final rule. 

SUMMARY: We are adopting a new airworthiness directive (AD) for B-N Group Ltd. Models BN2, 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-28-27, BN2A MK. III, BN2A MK. Ill-2, and 

BN2A MK. IIT-3 airplanes. This AD results from mandatory continuing airworthiness information 

(MCAI) issued 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: This AD is effective April I, 2014. 

The Director of the Federal Register approved the incorporation by reference of a certain 

publication listed in the AD as of April 1, 2014.

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, I3N-2A-6, BN-2A8, BN-2A-9, BN-2A-20, BN-2A-2l, BN-2A-26, BN-2A-27, BN-28-20, 8N-2B-2l, BN-28-26, BN28-27, BN2A MK. lll, BN2A MK. IJI-2, and BN2A MK. 111-3 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 ofthe 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: 

http://www.regulations.gov/#!documentDetaii;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: 

• Are consistent with the intent that was proposed in the NPRM (78 FR 64894, October 30, 

2013) for correcting the unsafe condition; and 

• Do not add any additional burden upon the public than was already proposed in the NPRM 

(78 FR 64894, October 30, 2013). 

2 
Costs of Compliance 

We estimate that this AD will affect 10 I 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 I 0 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 Tbis 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 ofthe Agency's authority. 

We are issuing this rulemaking under the authority described in "Subtitle VII, Part A, Subpart III, 

Section 44 70 l: 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 131 32. 

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 govemment. 

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.
