Airworthiness Directives; Societe de Motorisations Aeronautiques 
(SMA) SR305-230 and SR305-230-1 Reciprocating Engines

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule; request for comments.

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

SUMMARY: We are superseding an existing airworthiness directive (AD) 
for the products listed above. This AD results from mandatory 
continuing airworthiness information (MCAI) provided by the European 
Aviation Safety Agency (EASA) to identify and correct an unsafe 
condition on SMA SR305-230 and SR305-230-1 reciprocating engines. The 
MCAI states the following:

    Over a period of time, the alteration of one electronic control 
unit (ECU) electronic component can cause a rapid uncontrolled power 
increase. Several occurrences have already been reported during 
engine start or during engine warm-up. This condition, if not 
corrected, could result in the loss of control of the aircraft if 
the pilot fails to react appropriately by switching to the 
mechanical backup mode.

    We are issuing this AD to prevent a rapid uncontrolled power 
increase and possible loss of control of the airplane.

DATES: This AD becomes effective December 13, 2007. The Director of the 
Federal Register approved the incorporation by reference of SMA Service 
Bulletin (SB) No. SB-01-76-005, dated December 15, 2006, as of December 
13, 2007.
    We must receive comments on this AD by December 28, 2007.

SUPPLEMENTARY INFORMATION:

[[Page 67246]]

Discussion

    On October 31, 2006, we issued AD 2006-23-08, Amendment 39-14820 
(71 FR 65041, November 7, 2006). That AD required actions intended to 
address an unsafe condition on the products listed above. Since we 
issued AD 2006-23-08, SMA developed a terminating action for the unsafe 
condition. EASA, which is the Technical Agent for the Member States of 
the European Community, issued AD 2007-0033, dated February 13, 2007. 
That AD supersedes EASA EAD 2006-0312-E, which mandated a temporary 
corrective action to the rapid uncontrolled power increase. EASA AD 
2007-0033 retains the requirements of EASA AD 2006-0312-E, and also 
requires replacing all affected ECUs with a new part number ECU as 
terminating action. EASA AD 2007-0033 states:

    Over a period of time, the alteration of one electronic control 
unit (ECU) electronic component can cause a rapid uncontrolled power 
increase. Several occurrences have already been reported during 
engine start or during engine warm-up. This condition, if not 
corrected, could result in the loss of control of the aircraft if 
the pilot fails to react appropriately by switching to the 
mechanical backup mode.

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

Relevant Service Information

    SMA issued SB No. SB-01-76-005, dated December 15, 2006. The 
actions described in this service information are intended to correct 
the unsafe condition identified in EASA AD 2007-0033.

FAA's Determination and Requirements of This AD

    This product has been approved by the aviation authority of France, 
and is approved for operation in the United States. Pursuant to our 
bilateral agreement with France, they have notified us of the unsafe 
condition described in the EASA AD and service information referenced 
above. We are issuing this AD because we evaluated all the information 
provided by EASA and SMA, and determined the unsafe condition exists 
and is likely to exist or develop on other products of the same type 
design. This AD requires replacing all affected ECUs with a new part 
number ECU, as terminating action.

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 of 
the short compliance provided to correct the unsafe condition. 
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-2006-26102; Directorate 
Identifier 2006-NE-36-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.

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 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); and
    3. 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.

Reason

    (d) European Aviation Safety Agency (EASA) AD 2007-0033, dated 
February 13, 2007, states:


[[Page 67247]]


    Over a period of time, the alteration of one electronic control 
unit (ECU) electronic component can cause a rapid uncontrolled power 
increase. Several occurrences have already been reported during 
engine start or during engine warm-up. This condition, if not 
corrected, could result in the loss of control of the aircraft if 
the pilot fails to react appropriately by switching to the 
mechanical backup mode.

    We are issuing this AD to prevent a rapid uncontrolled power 
increase and possible loss of control of the airplane.

Actions and Compliance

    (e) Unless already done, do the following actions:
    (1) Before further flight, check if the ECU has a P/N listed in 
the Applicability section of this AD and a serial number (SN) of 131 
or below, except SNs 70, 71, 83, and 88. If it does, then do not 
operate the engine.
    (2) Remove and replace the ECU with an ECU P/N SP01160089-3, 
using SMA Service Bulletin (SB) No. SB-01-76-005, dated December 15, 
2006.
    (3) No later than 30 days after the effective date of this AD, 
replace all remaining affected P/N ECUs with an ECU P/N SP01160089-
3, using SMA SB No. SB-01-76-005, dated December 15, 2006.
    (4) After the effective date of this AD, do not install a spare 
ECU having a P/N listed in the Applicability section of this AD as a 
replacement part on any SMA SR305-230 or SR305-230-1 engine.

FAA AD Differences

    (f) This AD differs from the Mandatory Continuing Airworthiness 
Information (MCAI) and/or service information as follows:
    (1) EASA AD No. 2007-0033 requires compliance with the AD by 
March 31, 2007.
    (2) This AD, written later, requires compliance within 30 days 
after the effective date of the AD.

Other FAA AD Provisions

    (g) Alternative Methods of Compliance: The Manager, Engine 
Certification Office, FAA, has the authority to approve alternative
