14 CFR Part 39
[Docket No. FAA-2010-0499; Directorate Identifier 2010-NE-06-AD;
Amendment 39-16428; AD 2010-18-14]
RIN 2120-AA64
Airworthiness Directives; Bombardier-Rotax GmbH 912 F Series and
912 S Series Reciprocating Engines
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for the
products listed above. This AD results from mandatory continuing
airworthiness information (MCAI) issued by an aviation authority of
another country to identify and correct
[[Page 54463]]
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 issuing this AD to prevent the pump from exceeding the 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: This AD becomes effective October 13, 2010.
ADDRESSES: The Docket Operations office is located at Docket Management
Facility, U.S. Department of Transportation, 1200 New Jersey Avenue,
SE., West Building Ground Floor, Room W12-140, Washington, DC 20590-
0001.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM was published in the Federal Register on May 17, 2010 (75 FR
27487). That NPRM proposed 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.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM or on the determination of
the cost to the public.
Conclusion
We reviewed the available data and determined that air safety and
the public interest require adopting the AD as proposed.
Costs of Compliance
Based on the service information, we estimate that this AD will
affect about 50 products of U.S. registry. We also estimate that it
will take about 0.5 work-hour per product to comply with this AD. The
average labor rate is $85 per work-hour. Required parts will cost about
$650 per product. Based on these figures, we estimate the cost of the
AD on U.S. operators to be $34,625.
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.
Examining the AD Docket
You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Operations office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains this AD, the regulatory evaluation,
any comments received, and other information. The street address for
the Docket Operations office (phone (800) 647-5527) is provided in the
ADDRESSES section. Comments will be available in the AD docket shortly
after receipt.

Air transportation, Aircraft, Aviation safety, Safety.
Adoption of the Amendment
0
Accordingly, under the authority delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new AD:
2010-18-14 Bombardier-Rotax GmbH (Formerly Motorenfabrik): Amendment
39-16428. Docket No. FAA-2010-0499; Directorate Identifier 2010-NE-
06-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective October
13, 2010.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Bombardier-Rotax 912 F series and 912 S
series reciprocating engines with fuel pumps, part numbers (P/Ns)
892230, 892232, 892540 (standard version) or P/Ns 892235, 892236,
892545 (version including flexible fuel line), installed. These
engines are installed on, but not limited to, Diamond (formerly
HOAC) HK-36R Super Dimona, Aeromot AMT-200S Super Ximango; Diamond
DA20-A1 Katana; Scheibe SF 25C; Iniziative Industriali Italiane
S.p.A. Sky Arrow 650 TC, and 650 TCN airplanes.
Reason
(d) This AD results from mandatory continuing airworthiness
information (MCAI) issued 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.
[[Page 54464]]
We are issuing this AD to prevent the pump from exceeding the 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.
Actions and Compliance
(e) Unless already done, do the following actions.
(1) At the next maintenance, or within the next 25 hours of
engine operation, whichever occurs first, after the effective date
of this AD, remove affected fuel pumps, P/Ns 892230, 892232, 892235,
892236, 892540, or 892545.
(2) After the effective date of this AD, do not install fuel
pump, P/Ns 892230, 892232, 892235, 892236, 892540, or 892545, on any
engine.
FAA AD Differences
(f) 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 a fuel pump eligible for installation on the
airplane.
Other FAA AD Provisions
(g) Alternative Methods of Compliance (AMOCs): The Manager,
Engine Certification Office, FAA, has the authority to approve AMOCs
for this AD, if requested using the procedures found in 14 CFR
39.19.
