Airworthiness Directives; Short Brothers & Harland 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 Short Brothers & Harland Ltd. Model SC-7 Series 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 fatigue cracking, which could lead to structural failure of the nose landing gear (NLG). 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 January 22, 2015

Discussion
The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued AD No.: 2014-0246, dated November 12, 2014 (referred to after this as ``the MCAI''), to correct an unsafe condition for the specified products. The MCAI states:
A fracture of the nose landing gear (NLG) sliding tube was reported. The subsequent investigation determined fatigue cracking as possible cause of the failure.
This condition, if not detected and corrected, could lead to structural failure of the NLG, possibly resulting in loss of control of the aeroplane during take-off or landing.
To address this unsafe condition, the Messier-Dowty Ltd, the NLG manufacturer, issued Service Bulletin (SB) 32-17M to provide inspection instructions. Consequently Short Brothers PLC issued SB 32-74 which references Messier-Dowty Ltd SB 32-17M.
For the reasons described above, this AD requires one-time visual and fluorescent penetrant inspections and, depending on findings, accomplishment of applicable corrective action(s).
The MCAI requires you report the findings to Short Brothers PLC to obtain approved repair instructions and accomplish the repair accordingly. You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2014-
1001.
Relevant Service Information
Short Brothers & Harland Ltd. has issued Shorts Service Bulletin Number 32-74, dated November 1, 2014; and SAFRAN Messier-Buggatti-Dowty has issued Service Bulletin No. 32-17M, dated November 1, 2014. 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 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 24 products of U.S. registry. We also estimate that it would take about 5 work-hours 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 $10,200, or $425 per product.
In addition, we estimate that any necessary follow-on actions would take about 16 work-hours and require parts costing $25,000, for a cost of $26,360 per product. We have no way of determining the number of products that may need these actions.
Paperwork Reduction Act
A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB control number. The control number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in the Costs of Compliance section of this document and includes time for reviewing instructions, as well as completing and reviewing the collection of information. Therefore, all reporting associated with this AD is mandatory. Comments concerning the accuracy of this burden and suggestions for reducing the burden should be directed to the FAA at 800 Independence Ave. SW., Washington, DC 20591. ATTN: Information Collection Clearance Officer, AES-200.
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 proposed 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.
