Airworthiness Directives; Diamond Aircraft Industries Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for Diamond 
Aircraft Industries Model DA 40 NG 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 chafing between the charge air tubing and the engine 
firewall that may cause a hole in the charge air tubing, which could 
result in loss of charged air pressure with consequent loss of engine 
power and loss of control. We are issuing this AD to require actions to 
address the unsafe condition on these products.

DATES: This AD is effective May 21, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of May 21, 2013.

SUPPLEMENTARY INFORMATION:

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
AD 2013-0018, dated January 21, 2013 (referred to after this as ``the 
MCAI''), to correct an unsafe condition for the specified products. The 
MCAI states:

    An occurrence of loss of engine charge air pressure was 
reported, which prompted an in-flight Engine Control Unit warning. 
The investigation results identified that chafing caused a hole in 
the charge air tubing where it touched the engine firewall. Further 
investigation results identified other DA 40 NG aeroplanes with 
chafing marks in this area.
    To prevent chafing between the charged air tube and engine 
firewall, DAI issued Recommended SB 40NG-011 to replace the charged 
air elbow hose between the turbocharger and intercooler with an 
aluminium tube to improve the durability of the charged air system.
    After issuance of SB 40NG-011, an additional occurrence of a 
hole in a charge air tube was reported, apparently caused by 
chafing. The results of the subsequent investigation revealed that 
the improved design cannot assure the necessary clearance between 
the charged air tubing and surrounding parts.
    This condition, if not corrected, could lead to loss of charged 
air pressure, possibly resulting in loss of engine power and reduced 
control of the aeroplane.
    To address this unsafe condition, DAI issued Mandatory SB 40NG-
18, providing instructions to inspect the charged air tubing from 
the turbocharger to the intercooler and replacement of affected 
parts with an improved design.
    For the reasons described above, this AD requires repetitive 
inspections of charged air tubing for the presence of the chafing 
marks and, depending on findings, replacement of damaged tubing, or 
installation of improved design tubing.

You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Diamond Aircraft Industries GmbH has issued Mandatory Service 
Bulletin 40NG-018/1, dated November 20, 2012. 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 there 
is only one airplane on the U.S. registry affected by this unsafe 
condition, and the required modification has been completed on the 
specific airplane. Therefore, we determined that notice and opportunity 
for public comment before issuing this AD are unnecessary and that good 
cause exists for making this amendment effective in fewer than 30 days.

[[Page 25364]]

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-2013-0348; Directorate 
Identifier 2013-CE-005-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 would take about 2 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Required parts would cost about $1,381 per 
product.
    Based on these figures, we estimate the cost of the AD on U.S. 
operators to be $1,551, or $1,551 per product.

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.
