[Docket No. FAA-2010-0329; Directorate Identifier 2010-CE-016-AD]
RIN 2120-AA64

 
Airworthiness Directives; Various Aircraft Equipped With Rotax 
Aircraft Engines 912 A Series Engines

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

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the 
products listed above. This proposed AD results from mandatory 
continuing airworthiness information (MCAI) originated by an aviation 
authority of another country to identify and correct an unsafe 
condition on an aviation product. The MCAI describes the unsafe 
condition as:

    Due to high fuel pressure, caused by exceeding pressure in front 
of the mechanical fuel pump (e.g. due to an electrical fuel pump), 
in limited cases a deviation in the fuel supply could occur. This 
can result in exceeding of the fuel pressure and might cause engine 
malfunction and/or massive fuel leakage.

    We are proposing this AD to prevent the pump from causing excessive 
fuel pressure, which could result in engine malfunction or a massive 
fuel leak. These conditions could cause loss of control of the airplane 
or a fire.

DATES: We must receive comments on this proposed AD by July 23, 2010.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
AD No.: 2007-0060R1-E, dated April 20, 2007 (referred to after this as 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    Due to high fuel pressure, caused by exceeding pressure in front 
of the mechanical fuel pump (e.g. due to an electrical fuel pump), 
in limited cases a deviation in the fuel supply could occur. This 
can result in exceeding of the fuel pressure and might cause engine 
malfunction and/or massive fuel leakage.
    Non-compliance with these instructions could result in engine 
damages, personal injuries or death.

    The MCAI requires replacing the affected fuel pumps with a 
different part number fuel pump.
    The MCAI applies to all versions of Bombardier-Rotax GmbH 912 A, 
912 F, and 912 S series engines. Versions of the 912 F series and 912 S 
series engines are type certificated in the United States. However, the 
Model 912 A series engine installed in various aircraft does not have 
an engine type certificate; instead, the engine is part of the aircraft 
type design. You may obtain further information by examining the MCAI 
in the AD docket.

Relevant Service Information

    Rotax Aircraft Engines has issued Service Bulletin SB-912-053, 
dated April 13, 2007. 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 Proposed 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 proposing this AD because 
we evaluated all information and determined the unsafe condition exists 
and is likely to exist or develop on other products of the same type 
design.

Differences Between This Proposed AD and the MCAI or Service 
Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information 
provided in the MCAI and related service information.
    We might also have proposed different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
highlighted in a Note within the proposed AD.

Costs of Compliance

    We estimate that this proposed AD will affect 60 products of U.S. 
registry. We also estimate that it would take about .5 work-hour per 
product to

[[Page 32316]]

comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Required parts would cost about $650 
per product.
    Based on these figures, we estimate the cost of the proposed AD on 
U.S. operators to be $41,550, or $692.50 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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 proposed 
regulation:
    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 proposed AD and placed it in the AD docket.

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

Subject

    (d) Air Transport Association of America (ATA) Code 73: Engine 
Fuel and Control.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    Due to high fuel pressure, caused by exceeding pressure in front 
of the mechanical fuel pump (e.g. due to an electrical fuel pump), 
in limited cases a deviation in the fuel supply could occur. This 
can result in exceeding of the fuel pressure and might cause engine 
malfunction and/or massive fuel leakage.
    Non-compliance with these instructions could result in engine 
damages, personal injuries or death.
    We are issuing this AD to prevent the pump from causing 
excessive fuel pressure, which could result in engine malfunction or 
a massive fuel leak. These conditions could cause loss of control of 
the airplane or a fire. The MCAI requires replacing the affected 
fuel pumps with a different part number fuel pump.

Actions and Compliance

    (f) Unless already done, do the following actions:
    (1) Within the next 25 hours time-in-service after the effective 
date of this AD, replace fuel pump P/N 892230, 892232, 892540, 
892235, 892236, or 892545 with an FAA-approved fuel pump that does 
not have one of the P/Ns referenced above following Rotax Aircraft 
Engines Service Bulletin SB-912-053, dated April 13, 2007.
    (2) As of the effective date of this AD do not install fuel pump 
P/N 892230, 892232, 892540, 892235, 892236, or 892545, on any 
airplane.

FAA AD Differences

    Note: This AD differs from the MCAI and/or service information 
as follows: The MCAI requires replacing an affected fuel pump with 
fuel pump P/N 892542 or 892546. This AD requires replacement of an 
affected fuel pump with an FAA-approved fuel pump that does not have 
one of the P/Ns referenced in paragraph (f)(1) of this AD.

Other FAA AD Provisions

    (g) The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
Standards Office, FAA, has the authority to approve AMOCs for this 
AD, if requested using the procedures found in 14 CFR 39.19. Send
