Background
On July 1, 2008, Dassault Aviation
applied for a change to Type Certificate
(TC) No. A50NM to install an automatic
braking system in the Falcon Model
2000EX airplane. This is a pilotselectable function that allows earlier
maximum braking at landing without
pilot pedal input. When the autobrake
system is armed before landing, it
automatically commands maximum
braking at main wheels touchdown.
Normal procedures remain unchanged
VerDate Nov<24>2008
16:49 Dec 09, 2009
Jkt 220001
and call for manual braking after nose
wheel touchdown.
The current Federal Aviation
Regulations do not contain adequate
requirements to address the potentially
higher structural loads that could result
from this type of automatic braking
system. Title 14, Code of Federal
Regulations (14 CFR) 25.471 through
25.511 address ground handling loads,
but do not contain a specific
‘‘pitchover’’ requirement addressing the
loading on the nose gear, the nose gear
surrounding structure, and the forward
fuselage. The Dassault autobraking
system, which applies maximum
braking at the main wheels before the
nose gear touches down, will cause a
high nose gear sink rate, and potentially
higher gear and airframe loads.
Therefore, the FAA has determined that
a special condition is needed. The
special condition requires that the
airplane be designed to withstand the
loads resulting from maximum braking,
taking into account the effects of the
automatic braking system.
Type Certification Basis
Under the provisions of § 21.101,
Dassault Aviation must show that the
Falcon Model 2000EX, as changed,
continues to meet the applicable
provisions of the regulations
incorporated by reference in TC No.
A50NM, or the applicable regulations in
effect on the date of application for the
change. The regulations incorporated by
reference in the type certificate are
commonly referred to as the ‘‘original
type certification basis.’’ The regulations
incorporated by reference in TC No.
A50NM are as follows:
Title 14 Code of Federal Regulations
(14 CFR) part 25 as amended by
Amendments 25–1 through 25–69. In
addition, Dassault Aviation has elected
to comply with the following
amendments:
• Amendment 25–71 for § 25.365(e);
• Amendment 25–72 for §§ 25.783(g)
and 25.177;
• Amendment 25–75 for § 25.729(e);
• Amendment 25–79 for
§ 25.811(e)(2);
• Amendment 25–80 for § 25.1316.
In addition, the certification basis
includes certain special conditions,
exemptions, or later amended sections
of the applicable part that are not
relevant to this proposed special
condition.
If the Administrator finds that the
applicable airworthiness regulations
(i.e., part 25) do not contain adequate or
appropriate safety standards for the
Falcon Model 2000EX because of a
novel or unusual design feature, special
PO 00000
Frm 00013
Fmt 4700
Sfmt 4700
65395
conditions are prescribed under the
provisions of § 21.16.
In addition to the applicable
airworthiness regulations and special
conditions, the Falcon Model 2000EX
must comply with the fuel vent and
exhaust emission requirements of 14
CFR part 34 and the noise certification
requirements of 14 CFR part 36.
The FAA issues special conditions, as
defined in §§ 11.19 and 11.38, and they
become part of the type-certification
basis under § 21.101.
Special conditions are initially
applicable to the model for which they
are issued. Should the type certificate
for that model be amended later to
include any other model that
incorporates the same or similar novel
or unusual design feature, or should any
other model already included on the
same type certificate be modified to
incorporate the same or similar novel or
unusual design feature, the special
conditions would also apply to the other
model under § 21.101.
Novel or Unusual Design Features
The Falcon Model 2000EX will
incorporate the following novel or
unusual design features:
The airplane will be equipped with an
automatic braking system, which is a
pilot-selectable function that allows
earlier maximum braking at landing
without pilot pedal input. When the
autobrake system is armed before
landing, it automatically commands
maximum braking at main wheels
touchdown. This will cause a high nose
gear sink rate, and potentially higher
gear and airframe loads than would
occur with a traditional braking system.
Therefore, the FAA has determined that
a special condition is needed.
Discussion
The special condition defines a
landing pitchover condition that takes
into account the effects of the automatic
braking system. The special condition
defines the airplane configuration,
speeds, and other parameters necessary
to develop airframe and nose gear loads
for this condition. The special condition
requires that the airplane be designed to
support the resulting limit and ultimate
loads as defined in § 25.305.
Applicability
As discussed above, these special
conditions are applicable to the Falcon
Model 2000EX. Should Dassault
Aviation apply at a later date for a
change to the type certificate to include
another model incorporating the same
novel or unusual design feature, the
special conditions would apply to that
model as well.

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.

Background
On July 1, 2008, Dassault Aviation applied for a change to Type
Certificate (TC) No. A50NM to install an automatic braking system in
the Falcon Model 2000EX airplane. This is a pilot-selectable function
that allows earlier maximum braking at landing without pilot pedal

automatically commands maximum braking at main wheels touchdown. Normal
procedures remain unchanged and call for manual braking after nose
wheel touchdown.
The current Federal Aviation Regulations do not contain adequate

system.
Type Certification Basis
Under the provisions of Sec. 21.101, Dassault Aviation must show
that the Falcon Model 2000EX, as changed, continues to meet the
applicable provisions of the regulations incorporated by reference in
TC No. A50NM, or the applicable regulations in effect on the date of
application for the change. The regulations incorporated by reference
in the type certificate are commonly referred to as the ``original type
certification basis.'' The regulations incorporated by reference in TC
No. A50NM are as follows:
Title 14 Code of Federal Regulations (14 CFR) part 25 as amended by
Amendments 25-1 through 25-69. In addition, Dassault Aviation has
elected to comply with the following amendments:
Amendment 25-71 for Sec. 25.365(e);

Amendment 25-80 for Sec. 25.1316.
In addition, the certification basis includes certain special
conditions, exemptions, or later amended sections of the applicable
part that are not relevant to this proposed special condition.
If the Administrator finds that the applicable airworthiness
regulations (i.e., part 25) do not contain adequate or appropriate
safety standards for the Falcon Model 2000EX because of a novel or

provisions of Sec. 21.16.
In addition to the applicable airworthiness regulations and special
conditions, the Falcon Model 2000EX must comply with the fuel vent and
exhaust emission requirements of 14 CFR part 34 and the noise
certification requirements of 14 CFR part 36.
The FAA issues special conditions, as defined in Sec. Sec. 11.19
and 11.38, and they become part of the type-certification basis under
Sec. 21.101.
Special conditions are initially applicable to the model for which
they are issued. Should the type certificate for that model be amended
later to include any other model that incorporates the same or similar
novel or unusual design feature, or should any other model already
included on the same type certificate be modified to incorporate the
same or similar novel or unusual design feature, the special conditions
would also apply to the other model under Sec. 21.101.
Novel or Unusual Design Features
The Falcon Model 2000EX will incorporate the following novel or
unusual design features:
The airplane will be equipped with an automatic braking system,
which is a pilot-selectable function that allows earlier maximum
braking at landing without pilot pedal input. When the autobrake system
is armed before landing, it automatically commands maximum braking at
main wheels touchdown. This will cause a high nose gear sink rate, and
potentially higher gear and airframe loads than would occur with a
traditional braking system. Therefore, the FAA has determined that a
special condition is needed.
Discussion
The special condition defines a landing pitchover condition that
takes into account the effects of the automatic braking system. The
special condition defines the airplane configuration, speeds, and other
parameters necessary to develop airframe and nose gear loads for this
condition. The special condition requires that the airplane be designed
to support the resulting limit and ultimate loads as defined in Sec.
25.305.
Applicability
As discussed above, these special conditions are applicable to the
Falcon Model 2000EX. Should Dassault Aviation apply at a later date for
a change to the type certificate to include another model incorporating
the same novel or unusual design feature, the special conditions would
apply to that model as well.

Conclusion
This action affects only certain novel or unusual design features
on one model of airplanes. It is not a rule of general applicability.

The Proposed Special Condition
0
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.
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 Sec. 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 Sec. 25.305.
