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.

SUPPLEMENTARY INFORMATION: 

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 


emcdonald on DSK67QTVN1PROD with RULES
70210 Federal Register / Vol. 78, No. 227 / Monday, November 25, 2013 / Rules and Regulations 

for the Member States of the European 

Community, has issued AD No.: 2013– 

0264–E, dated October 29, 2013 

(referred to after this as ‘‘the MCAI’’), to 

correct an unsafe condition for the 

specified products. The MCAI states: 

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 workhours 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.

Federal Register / Vol. 78, No. 227 / Monday, November 25, 2013 / Rules and Regulations 70211 

(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

mount to the firewall attachment plate. We 

are issuing this AD to prevent failure of the 

engine mounts, which could cause reduced 

structural integrity of the airplane and could 

result in engine separation. 

(f) Actions and Compliance 

Unless already done, do the following 

actions specified in paragraphs (f)(1) through 

(f)(3) of this AD. 

(1) Before further flight after November 25, 

2013 (the effective date of this AD) inspect 

the welds on the engine mount part number
