SUPPLEMENTARY INFORMATION:

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued AD 
No.: 2012-0269, dated December 19, 2012 (referred to after this as 
``the MCAI''), to correct

[[Page 16605]]

an unsafe condition for the specified products. The MCAI states:

    Three occurrences of in-flight engine control unit (ECU) A/B 
caution initiation were reported which were followed by an un-
commanded power reduction. All of these events happened in snow or 
moist conditions and resolved themselves in warmer air conditions. 
The subsequent investigation identified that the engine air inlet 
filter is subject to icing under certain, currently not fully 
identified, icing conditions.
    The DA 42 NG is equipped with a manually controlled alternate 
air valve which bypasses the inlet air filter and provides 
sufficient air to the engine. The aeroplane flight manual (AFM) 
procedures include procedure for activation of the alternate air 
valve in case of power loss but these procedures were not applied by 
the pilots in these events.
    The DA 42 NG is certified for flights in known icing conditions 
during which engine inlet filter icing may occur, therefore it is 
expected that flights into suspected icing conditions, where inlet 
filter icing may occur, is more likely.
    Additional occurrence of dual ECU A/B caution initiation was 
reported followed by loss of power and loss of flight altitude. 
Again, the alternate air valve was not opened, which would have 
immediately resolved the situation.
    It has been recognized that the engine control ECU A/B caution 
triggers the pilot to focus on engine electrical or fuel supply 
problem and thus causes a misinterpretation of the situation. It has 
also been identified that the conditions during which air filter 
icing may occur could include the critical take-off and climb phase.
    This condition, if not corrected, could lead to a loss of engine 
power and reduced controllability of the aeroplane.
    To address this unsafe condition, DAI revised Supplement S03 
``Ice Protection System'' to the aeroplane AFM and issued Service 
Information SI 42NG-039 to advise the owners and pilots of the 
proper use of the engine alternate air.
    For the reasons described above, this AD requires revision of 
the aeroplane AFM to incorporate updated Normal and Abnormal 
Operating procedures for alternate air valve operation during 
suspected rain, snow or visible moisture conditions.
    The requirement of this AD is considered as an interim action. 
DAI is currently developing a modification that addresses the unsafe 
condition identified in this AD.

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

Relevant Service Information

    Diamond Aircraft Industries GmbH has issued the following service 
information:
     Service Information No. SI 42NG-039, dated November 14, 
2012;
     DA 42 NG AFM Temporary Revision TR-M[Auml]M 42-701, Doc. 
7.01.15-E, dated November 20, 2012;
     DA 42 NG AFM Temporary Revision TR-M[Auml]M 42-701, Doc. 
7.01.16-E, dated November 20, 2012; and
     DA 42 NG AFM Temporary Revision TR-O[Auml]M-42-200/a, Doc. 
7.01.15-E, dated November 30, 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.

Interim Action

    We consider this AD interim action. The type certificate holder is 
looking at developing a modification that addresses the unsafe 
condition identified in this AD. When this modification is established, 
we may take additional rulemaking action to mandate the modification.

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 this 
condition, if not corrected, could lead to a loss of engine power and 
reduced controllability of the airplane. 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-2013-0247; Directorate 
Identifier 2013-CE-001-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 26 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 AD. The average labor rate 
is $85 per work-hour. Required parts would cost about $0 per product.
    Based on these figures, we estimate the cost of the AD on U.S. 
operators to be $2,210, or $85 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

[[Page 16606]]

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.
