Airworthiness Directives; XtremeAir GmbH Airplanes
AGENCY:
Federal Aviation Administration (FAA), DOT.
ACTION:
Final rule; request for comments.
SUMMARY:
We are adopting a new airworthiness directive (AD) for XtremeAir GmbH Model XA42 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as cracks in a weld seam between the lower left landing gear attachment bearing and the lower engine mount to the firewall attachment plate, which could reduce the structural integrity of the airplane and could result in engine separation. We are issuing this AD to require actions to address the unsafe condition on these products.
DATES:
This AD is effective November 25, 2013.
The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of November 25, 2013.
We must receive comments on this AD by January 9, 2014.

SUPPLEMENTARY INFORMATION:
Discussion
[top] The European Aviation Safety Agency (EASA), which is the Technical Agent
A crack was reported by an operator in a weld seam between the lower left landing gear attachment bearing and the lower engine mount to firewall attachment plate. Further investigation showed that all engine mounts from a specific supplier may be affected.
This condition, if not detected and corrected, could lead to engine separation of the aeroplane and could severely affect the structural integrity of the aeroplane.
To address this unsafe condition, XtremeAir GmbH issued Service Bulletin SB-2013-008-A.03 to provide inspection and replacement instructions for the engine mount.
For the reason described above, this AD requires repetitive inspection of engine mounts and, in case of findings, replacement of the engine mount.
You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating it in Docket No. FAA-2013-0998.
Relevant Service Information
XtremeAir GmbH has issued Mandatory Service Bulletin SB-2013-008, Version A.03, dated October 25, 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 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 issuing this AD because we evaluated all information provided by the State of Design Authority and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design.
FAA's Determination of the Effective Date
An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because cracks in a weld seam between the lower left landing gear attachment bearing and the lower engine mount to the firewall attachment plate affects the structural integrity of the airplane and could lead to engine separation. Therefore, we determined that notice and opportunity for public comment before issuing this AD are impracticable and that good cause exists for making this amendment effective in fewer than 30 days.
Comments Invited
This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include "Docket No. FAA-2013-0998; Directorate Identifier 2013-CE-047-AD" at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those comments.
We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD.
Costs of Compliance
We estimate that this AD will affect 1 product of U.S. registry. We also estimate that it will take about 4 work-hours 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 $340.
In addition, we estimate that any necessary follow-on actions will take about 16 work-hours and require parts costing $4,057, for a cost of $5,417 per product.
According to the manufacturer, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate.
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 AD will not have federalism implications under Executive Order 13132. 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 government.
For the reasons discussed above, I certify that 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.

Adoption of the Amendment
Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:
PART 39-AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:
Authority:
49 U.S.C. 106(g), 40113, 44701.
§ 39.13 [Amended]
2. The FAA amends § 39.13 by adding the following new AD:
2013-23-19XtremeAir GmbH: Amendment 39-17674; Docket No. FAA-2013-0998; Directorate Identifier 2013-CE-047-AD.
(a) Effective Date
[top] This airworthiness directive (AD) becomes effective November 25, 2013.
(b) Affected ADs
None.
(c) Applicability
This AD applies to XtremeAir GmbH Model XA42 airplanes, all serial numbers, that:
(1) Are certificated in any category; and
(2) have engine mount part number (P/N) XA42-7120-151 (manufactured by Szel-Tech), all serial numbers up to and including 036, installed.
