The Proposed Special Condition
Accordingly, the Federal Aviation
Administration (FAA) proposes the
following special condition as part of
the type certification basis for Dassault
Aviation Falcon Model 2000EX
airplanes.
■
AGENCY: Federal Aviation
Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule; request for
comments.
Landing Pitchover Condition
A landing pitchover condition must
be addressed that takes into account the
effect of the autobrake system. The
airplane is assumed to be at the design
maximum landing weight, or at the
maximum weight allowed with the
autobrake system on. The airplane is
assumed to land in a tail-down attitude
and at the speeds defined in § 25.481.
Following main gear contact, the
airplane is assumed to rotate about the
main gear wheels at the highest pitch
rate allowed by the autobrake system.
This is considered a limit load
condition from which ultimate loads
must also be determined. Loads must be
determined for critical fuel and payload
distributions and centers of gravity.
Nose gear loads, as well as airframe
loads, must be determined. The airplane
must support these loads as described in
§ 25.305.
SUMMARY: We are adopting a new
airworthiness directive (AD) for the
products listed above. This 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:
An operator of A330 aeroplane fitted with
Rolls-Royce (RR) Trent 772 B engines
experienced an engine#1 uncontained
multiple turbine blade failure. Investigations
have shown that High Pressure/Intermediate
Pressure (HP/IP) oil vent tubes are prone to
be affected by carbon deposit or to be
damaged by their outer heat shields leading
to a fire inside or outside the vent tube and
resulting into IP Turbine (IPT) disc drive arm
fracture and thus IPT disc overspeed.
If not corrected, IPT disc overspeed could
lead to an uncontained engine failure, i.e.
multiple turbine blade failure or HP/IP
turbine disc burst, which would constitute an
unsafe condition.

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
Airworthiness Directive 2009–0075,
dated April 6, 2009 (referred to after this
as ‘‘the MCAI’’), to correct an unsafe
condition for the specified products.
The MCAI states:
An operator of A330 aeroplane fitted with
Rolls-Royce (RR) Trent 772 B engines
experienced an engine#1 uncontained
multiple turbine blade failure. Investigations
have shown that High Pressure/Intermediate
Pressure (HP/IP) oil vent tubes are prone to
be affected by carbon deposit or to be
damaged by their outer heat shields leading
to a fire inside or outside the vent tube and
resulting into IP Turbine (IPT) disc drive arm
fracture and thus IPT disc overspeed.
If not corrected, IPT disc overspeed could
lead to an uncontained engine failure, i.e.
multiple turbine blade failure or HP/IP
turbine disc burst, which would constitute an
unsafe condition.
In order to protect IPT from overspeed,
EASA AD 2008–0101 required to activate
Intermediate Pressure Turbine Overspeed
(IPTOS) protection function by Data Entry
Plug (DEP) reprogramming, which consists in
limiting the IPT speed (Engine Thrust) when
overheat is detected in IPT, for all A330
aeroplanes fitted with RR Trent 700 engines
and equipped with Multi Mode Receivers.
Original issue of AD 2008–0101 had a
limited applicability due to Flight Warning
Computer compatibility issue with aircraft
not equipped with Multi Mode Receivers.
Airbus has now developed a new Flight

Federal Register / Vol. 74, No. 236 / Thursday, December 10, 2009 / Rules and Regulations
Warning Computer standard T2 whose
embodiment is also possible on A330
aeroplane fitted with RR Trent 700 engines
not equipped with Multi Mode Receivers.
For the above described reasons, this AD
retains the requirement of EASA AD 2008–
0101, which is superseded, and extends the
applicability to all A330 aeroplanes fitted
with RR Trent 700 engines.
You may obtain further information by
examining the MCAI in the AD docket.
Relevant Service Information
Airbus has issued Mandatory Service
Bulletin A330–73–3049, Revision 01,
dated November 13, 2008. The actions
described in this service information are
intended to correct the unsafe condition
identified in the MCAI.
FAA’s Determination and Requirements
of This 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 the State of
Design Authority, we have been notified
of the unsafe condition described in the
MCAI and service information
referenced above. We are issuing this
AD because we evaluated all pertinent
information and determined the unsafe
condition exists and is likely to exist or
develop on other products of the same
type design.
There are no products of this type
currently registered in the United States.
However, this rule is necessary to
ensure that the described unsafe
condition is addressed if any of these
products are placed on the U.S. Register
in the future.

Differences Between the 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 required 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 AD.
FAA’s Determination of the Effective
Date
Since there are currently no domestic
operators of this product, notice and
opportunity for public comment before
issuing this AD are unnecessary.

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–2009–1109;
Directorate Identifier 2009–NM–068–
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 https://
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.

2009–25–04 Airbus: Amendment 39–16123.
Docket No. FAA–2009–1109; Directorate
Identifier 2009–NM–068–AD.
Effective Date
(a) This airworthiness directive (AD)
becomes effective December 28, 2009.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Airbus Model A330–
243, –341,–342, and –343 airplanes, all
manufacturing serial numbers (MSN), except
those on which Airbus Modification 56722
has been embodied in production.
Subject
(d) Air Transport Association (ATA) of
America Code 73: Engine fuel and control.
Reason
(e) The mandatory continued airworthiness
information (MCAI) states:
An operator of A330 aeroplane fitted with
Rolls-Royce (RR) Trent 772 B engines
experienced an engine #1 uncontained
multiple turbine blade failure. Investigations
have shown that High Pressure/Intermediate
Pressure (HP/IP) oil vent tubes are prone to
be affected by carbon deposit or to be
damaged by their outer heat shields leading
to a fire inside or outside the vent tube and
resulting into IP Turbine (IPT) disc drive arm
fracture and thus IPT disc overspeed.
If not corrected, IPT disc overspeed could
lead to an uncontained engine failure, i.e.
multiple turbine blade failure or HP/IP
turbine disc burst, which would constitute an
unsafe condition.
In order to protect IPT from overspeed,
EASA AD 2008–0101 required to activate

Plug (DEP) reprogramming, which consists in
limiting the IPT speed (Engine Thrust) when
overheat is detected in IPT, for all A330
aeroplanes fitted with RR Trent 700 engines
and equipped with Multi Mode Receivers.
Original issue of AD 2008–0101 had a
limited applicability due to Flight Warning
Computer compatibility issue with aircraft
not equipped with Multi Mode Receivers.
Airbus has now developed a new Flight
Warning Computer standard T2 whose
embodiment is also possible on A330
aeroplane fitted with RR Trent 700 engines
not equipped with Multi Mode Receivers.
For the above described reasons, this AD
retains the requirement of EASA AD 2008–
0101, which is superseded, and extends the
applicability to all A330 aeroplanes fitted
with RR Trent 700 engines.
Actions and Compliance
(f) Unless already done, do the following
actions: Within 12 months after the effective
date of this AD, do the actions specified in
paragraph (f)(1) of this AD.
(1) Reprogram the data entry plug on both
engines to activate the intermediate pressure
turbine overspeed protection function,
including doing applicable revisions of the
Airplane Flight Manual (AFM), in
accordance with the Accomplishment
Instructions of Airbus Mandatory Service
Bulletin A330–73–3049, Revision 01, dated
November 13, 2008.
Note 1: IPTOS function activation has the
following operational consequences:
Modification of the AFM and the flightcrew
operating manual (FCOM). Accomplishment
of the actions specified in Airbus Mandatory
Service Bulletin A330–73–3049, Revision 01,
dated November 13, 2008 (Airbus
Modification 56722), cancels Airbus A330
AFM Supplement 6.03.08, dated June 2,
2006; and Volumes 1 and 3 (1.70.20, 1.70.95,
and 3.02.70) of the Airbus A330 FCOM have
been modified.
(2) Actions accomplished before the
effective date of this AD in accordance with
Airbus Mandatory Service Bulletin A330–73–
3049, dated November 14, 2007, are
considered acceptable for compliance with
the corresponding action specified in
paragraph (f)(1) of this AD.

SUMMARY: The FAA is revising an
existing airworthiness directive (AD),
which applies to all Airbus Model
A300–600 series airplanes. That AD
currently requires revising the
Airworthiness Limitations section of the
Instructions for Continued
Airworthiness to incorporate new
limitations for fuel tank systems. This
AD clarifies the intended effect of the
AD on spare and on-airplane fuel tank
system components. This AD results
from fuel system reviews conducted by
the manufacturer. We are issuing this
AD to prevent the potential of ignition
sources inside fuel tanks, which, in
combination with flammable fuel vapors
caused by latent failures, alterations,
repairs, or maintenance actions, could
result in fuel tank explosions and
consequent loss of the airplane.
DATES: This AD is effective December
28, 2009.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in the AD
as of December 28, 2009.
On June 27, 2007 (72 FR 28827, May

equipped with Multi Mode Receivers. Airbus has now developed a new
Flight
[[Page 65397]]
Warning Computer standard T2 whose embodiment is also possible on
A330 aeroplane fitted with RR Trent 700 engines not equipped with
Multi Mode Receivers.
For the above described reasons, this AD retains the requirement
of EASA AD 2008-0101, which is superseded, and extends the
applicability to all A330 aeroplanes fitted with RR Trent 700
engines.
You may obtain further information by examining the MCAI in the AD
docket.
Relevant Service Information
Airbus has issued Mandatory Service Bulletin A330-73-3049, Revision
01, dated November 13, 2008. The actions described in this service
information are intended to correct the unsafe condition identified in
the MCAI.
FAA's Determination and Requirements of This 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 the State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information referenced above. We are issuing this AD because we
evaluated all pertinent information and determined the unsafe condition
exists and is likely to exist or develop on other products of the same
type design.
There are no products of this type currently registered in the
United States. However, this rule is necessary to ensure that the
described unsafe condition is addressed if any of these products are
placed on the U.S. Register in the future.
Differences Between the 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 required 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 AD.
FAA's Determination of the Effective Date
Since there are currently no domestic operators of this product,
notice and opportunity for public comment before issuing this AD are
unnecessary.
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-2009-1109; Directorate
Identifier 2009-NM-068-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 https://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.

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:
2009-25-04 Airbus: Amendment 39-16123. Docket No. FAA-2009-1109;
Directorate Identifier 2009-NM-068-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective December
28, 2009.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Airbus Model A330-243, -341,-342, and -
343 airplanes, all manufacturing serial numbers (MSN), except those
on which Airbus Modification 56722 has been embodied in production.
Subject
(d) Air Transport Association (ATA) of America Code 73: Engine
fuel and control.
Reason
(e) The mandatory continued airworthiness information (MCAI)
states:
An operator of A330 aeroplane fitted with Rolls-Royce (RR) Trent
772 B engines experienced an engine 1 uncontained multiple
turbine blade failure. Investigations have shown that High Pressure/
Intermediate Pressure (HP/IP) oil vent tubes are prone to be
affected by carbon deposit or to be damaged by their outer heat
shields leading to a fire inside or outside the vent tube and
resulting into IP Turbine (IPT) disc drive arm fracture and thus IPT
disc overspeed.
If not corrected, IPT disc overspeed could lead to an
uncontained engine failure, i.e. multiple turbine blade failure or
HP/IP turbine disc burst, which would constitute an unsafe
condition.
In order to protect IPT from overspeed, EASA AD 2008-0101
required to activate
[[Page 65398]]
Intermediate Pressure Turbine Overspeed (IPTOS) protection function
by Data Entry Plug (DEP) reprogramming, which consists in limiting
the IPT speed (Engine Thrust) when overheat is detected in IPT, for
all A330 aeroplanes fitted with RR Trent 700 engines and equipped
with Multi Mode Receivers.
Original issue of AD 2008-0101 had a limited applicability due
to Flight Warning Computer compatibility issue with aircraft not
equipped with Multi Mode Receivers. Airbus has now developed a new
Flight Warning Computer standard T2 whose embodiment is also
possible on A330 aeroplane fitted with RR Trent 700 engines not
equipped with Multi Mode Receivers.
For the above described reasons, this AD retains the requirement
of EASA AD 2008-0101, which is superseded, and extends the
applicability to all A330 aeroplanes fitted with RR Trent 700
engines.
Actions and Compliance
(f) Unless already done, do the following actions: Within 12
months after the effective date of this AD, do the actions specified
in paragraph (f)(1) of this AD.
(1) Reprogram the data entry plug on both engines to activate
the intermediate pressure turbine overspeed protection function,
including doing applicable revisions of the Airplane Flight Manual
(AFM), in accordance with the Accomplishment Instructions of Airbus
Mandatory Service Bulletin A330-73-3049, Revision 01, dated November
13, 2008.
Note 1: IPTOS function activation has the following operational
consequences: Modification of the AFM and the flightcrew operating
manual (FCOM). Accomplishment of the actions specified in Airbus
Mandatory Service Bulletin A330-73-3049, Revision 01, dated November
13, 2008 (Airbus Modification 56722), cancels Airbus A330 AFM
Supplement 6.03.08, dated June 2, 2006; and Volumes 1 and 3
(1.70.20, 1.70.95, and 3.02.70) of the Airbus A330 FCOM have been
modified.
(2) Actions accomplished before the effective date of this AD in
accordance with Airbus Mandatory Service Bulletin A330-73-3049,
dated November 14, 2007, are considered acceptable for compliance
with the corresponding action specified in paragraph (f)(1) of this
AD.
