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. 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.

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA AD No.: 2013-0215, dated September 16, 2013 (referred to after this as “the MCAI”), 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.

You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating it in Docket No. FAA-2013-0924.

Relevant Service Information

Britten-Norman Aircraft Limited has issued Service Bulletin No. SB 334, Issue 1, dated August 30, 2013. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI.

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 Start Printed Page 64895MCAI 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 101 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 $8,585, or $85 per product.

In addition, we estimate that any necessary follow-on actions would 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 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.

(a) Comments Due Date

We must receive comments by December 16, 2013.

(b) Affected ADs

None.

(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, 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, 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:

(1) Within the next 6 months after 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 section 6 ACTION of 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 section 6 ACTION of 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 section 6 ACTION of Britten-Norman Aircraft Limited Service Bulletin No. SB 334, Issue 1, dated August 30, 2013.

(4) After 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: taylor.martin@faa.gov. Before using any approved AMOC on any 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.
