T his 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. Th e MC A I describes the unsafe condition as damage of the cable slidi ng end assembly and installat ion 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: Th is AD is effecti ve April I , 2014. The Director of the Federa l 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 ofp roposed 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 BN 2A MK. 111-3 airplanes. That NPRM was publi shed in the Federal Register on October 30, 2013 (78 FR 64894). That NPRM prop osed to correct an unsafe condition for the specified products. The M CAI 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 ins talled which may have contributed to the failures. This condition , if not detected and corrected, could result in reduced engi ne control, possibly resulting in reduced control ofthe aeroplane. To address this potential unsafe condition, Br itten-Norman Aircraft have issued Service Bulletin (SB) 334 to provide inspection instructions
. For the reason described above, this AD requires a one -time inspecti o n 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 t he 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 propo sed 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 correcti ng 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)
.

### Costs of Compliance We estimate that this AD will affect 10 I products of U
. S. registry. We also estima te that i t w ill take about 1 work-hour per product to comply w i th the basic requirements of this AD. T he 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 w ork

-hours and require parts co sting $4,800 (4 per airplane) , for a cost of$5,650 per product. We have no way of determinin g the number of products that may nee d these actions. A uthority f or T bis Ru lemaking Title 49 ofthe United States Code specifies the FAA's authority to issue rules o n aviation safety. Subtitle I , section 1 06 , de scribes the au thority of the FAA Administrator. "Subtitle VII : Aviat ion Programs," describ es in mo re detail the scope ofthe Agency's author ity
. We are issuing th is rul emaking under the authority described in "Subtitle VII , Part A , Sub p art III , Section 4 4 70 

### l : Gene ral re q uirements." Under that section, Congress charge s the FAA wit h pro moting safe flight of civil aircraft in air commerce by p res cribing regulations for practices , methods , an d procedures the Administrato r finds necessary for safety in air commerce. This re gulat ion is withi n the scope o f that authori ty because it address e s an un safe condition that is likely to exist o r d evelop on products identified 

### in this ru lemaking acti on. Regu latory Fi nd in gs We determined that th is AD will not have federalism implicatio ns under E xecutive Order 13 132
. T his AD will not have a sub stantial direct e ff ec t on the States, on the relationship b etw een the national go vernment and th e States , or on the distribution o f power and responsibilities among the various levels of govemment. For the reasons discu s sed above , I certi f y this AD: (1) Is not a "significa nt regulatory action" under E xecutive Order 12866 , (2) Is not a "signific a nt rule" under the DOT Regulatory Polic ies and Procedures (4 4 F R 11034 , February 26 , 1979) , (3) W ill no t affect intrastate aviation in Alaska, and (4) Will not have a significant economic impact, posi tive or negative, on a substant ial numb er of small entities under the criteria o f the Regulatory Flexibility Act.
