These special conditions are issued for the Bombardier Inc. Model BD-700-2A12 and Model BD-700-2A13 airplanes. This airplane will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. This design feature is an autobrake system that allows earlier braking at landing without pedal input from the pilot. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

Administration, 2200 South 216th Street, Des Moines, Washington 98198;
telephone and fax 206-231-3207; email Mark.Freisthler@faa.gov.

SUPPLEMENTARY INFORMATION: The FAA has determined that notice of, and
opportunity for prior public comment on, these special conditions is
impracticable because these procedures would significantly delay
issuance of the design approval and thus delivery of the affected
airplanes.
In addition, the substance of these special conditions has been
published in the Federal Register for public comment in several prior
instances with no substantive comments received. The FAA, therefore,
finds it unnecessary to delay the effective date and finds that good
cause exists for making these special conditions effective upon
publication in the Federal Register.

Comments Invited

We invite interested people to take part in this rulemaking by
sending written comments, data, or views. The most helpful comments
reference a specific portion of the special conditions, explain the
reason for any recommended change, and include supporting data.
We will consider all comments we receive by the closing date for
comments. We may change these special conditions based on the comments
we receive.

Background

On May 30, 2012, Bombardier Inc. (Bombardier) applied for an
amendment to Type Certificate No. T00003NY to include new Model BD-700-
2A12 and Model BD-700-2A13 airplanes. These airplanes, which are
derivatives of the BD-700 series airplanes currently approved under
Type Certificate No. T00003NY, are marketed as the Bombardier Global
7000 and Global 8000, respectively. These airplanes are twin engine,
transport category, executive interior business jets with a maximum
certified passenger capacity of 19. The maximum takeoff weight for the
Model BD-700-2A12 and Model BD-700-2A13 is 106,250 pounds and 104,800
pounds, respectively.

Type Certification Basis

Under the provisions of title 14, Code of Federal Regulations (14
CFR) 21.101, Bombardier must show that the Model BD-700-2A12 and Model
BD-700-2A13 airplanes meet the applicable provisions of the regulations
listed in Type Certificate No. T00003NY, or the applicable regulations
in effect on the date of application for the change, except for earlier
amendments as agreed upon by the FAA.
If the Administrator finds that the applicable airworthiness
regulations (i.e., 14 CFR part 25) do not contain adequate or
appropriate safety standards for the Bombardier Model BD-700-2A12 and
Model BD-700-2A13 airplanes because of a novel or unusual design
feature, special conditions are prescribed under the provisions of
Sec. 21.16.
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 novel or
unusual design feature, or should any other model already included on
the same type certificate be modified to incorporate the same novel or
unusual design feature, these special conditions would also apply to
the other model under Sec. 21.101.
In addition to the applicable airworthiness regulations and special
conditions, the Bombardier Model BD-700-2A12 and Model BD-700-2A13
airplanes 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 14 CFR 11.19, in
accordance with Sec. 11.38, and they become part of the type
certification basis under Sec. 21.101.

Novel or Unusual Design Features

The Bombardier Model BD-700-2A12 and Model BD-700-2A13 airplanes
will incorporate the following novel or unusual design feature:
The autobrake system on the Bombardier Model BD-700-2A12 and Model
BD-700-2A13 airplanes is a pilot-selectable function that allows
earlier braking at landing without pedal input from the pilot. When the
pilot arms the autobrake system before landing, the system
automatically commands braking when the main wheels touch down. This
might cause a high nose gear sink rate, and potentially higher gear and
airframe loads than would occur with a traditional braking system.

Discussion

These special conditions define a landing pitchover condition that
accounts for the effects of the autobrake system. The special
conditions define the airplane configuration, speeds, and other
parameters necessary to develop airframe and nose gear loads for this
condition. The special conditions require that the airplane be designed
to support the resulting limit and ultimate loads as defined in Sec.
25.305, ``Strength and deformation.''
These special conditions contain the additional safety standards
that the Administrator considers necessary to establish a level of
safety equivalent to that established by the existing airworthiness
standards.

Applicability

As discussed above, these special conditions are applicable to the
Bombardier Inc. Model BD-700-2A12 and Model BD-700-2A13 airplanes.
Should Bombardier apply at a later date for a change to the type
certificate to include another model incorporating the same novel or
unusual design feature, these special conditions would apply to that
model as well.

Conclusion

This action affects only a certain novel or unusual design feature
on Bombardier Model BD-700-2A12 and Model BD-700-2A13 airplanes. It is
not a rule of general applicability.

The Special Conditions

Accordingly, pursuant to the authority delegated to me by the

[[Page 24654]]

Administrator, the following special conditions are issued as part of
the type certification basis for Bombardier Model BD-700-2A12 and Model
BD-700-2A13 airplanes.

Autobraking System Structural Loads

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 at the speeds defined by Sec. 25.481.
Following main gear contact, the airplane is assumed to rotate about
the main gear wheels at the highest pitch rate generated by the
autobrake system. This is considered a limit load condition from which
ultimate loads must also be determined. Loads must be determined for a
critical fuel and payload distribution 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.
