Background
On January 11, 2008, Learjet Inc.
applied for a type certificate for a new
Model LJ–200–1A10 airplane. This
airplane is 68 feet long with a 65-foot
wing span and accommodates up to 10
passengers. The LJ–200–1A10 airplane
uses a hydrophobic windshield coating,
in lieu of windshield wipers, for an
unobstructed outside view from the
pilot compartment.
Type Certification Basis
Under the provisions of Title 14, Code
of Federal Regulations (14 CFR) 21.17,
Learjet Inc. must show that the Model
LJ–200–1A10 airplane meets the
applicable provisions of part 25, as
amended by Amendments 25–1 through
25–123.
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 Model LJ–200–1A10 airplane
because of a novel or unusual design
feature, special conditions are
prescribed under the provisions of
§ 21.16.
In addition to the applicable
airworthiness regulations and special
conditions, the Model LJ–200–1A10
airplane must comply with the fuel-vent
and exhaust-emission requirements of
14 CFR part 34, and the noisecertification requirements of 14 CFR
part 36, and the FAA must issue a
finding of regulatory adequacy pursuant
PO 00000
Frm 00006
Fmt 4702
Sfmt 4702
63851
to § 611 of Public Law 92–574, the
‘‘Noise Control Act of 1972.’’
The FAA issues special conditions, as
defined in 14 CFR 11.19, in accordance
with § 11.38, and they become part of
the type-certification basis under
§ 21.17(a)(2).
Novel or Unusual Design Features
The Learjet Model LJ–200–1A10
airplane will incorporate the following
novel or unusual design features:
The Model LJ–200–1A10 airplane
flight deck design incorporates a
hydrophobic windshield coating to
provide, during precipitation, an
adequate outside view from the pilot
compartment. Sole reliance on such a
coating, without windshield wipers,
constitutes a novel or unusual design
feature for which the applicable
airworthiness regulations do not contain
adequate or appropriate safety
standards. Therefore, a special
condition is required to provide a level
of safety equivalent to that established
by the regulations.
Discussion
14 CFR 25.773(b)(1) requires a means
to maintain a clear portion of the
windshield for both pilots to have a
sufficiently extensive view along the
flight path during precipitation
conditions. The regulations require this
means to maintain such an area during
heavy-rain precipitation at airplane
speeds up to 1.5 VSR1. Hydrophobic
windshield coatings may depend to
some degree on airflow to maintain a
clear-vision area. The heavy rain and
high speed conditions specified in the
current rule do not necessarily represent
the limiting condition for this new
technology. For example, airflow over
the windshield, which may be necessary
to remove moisture from the
windshield, may not be adequate to
maintain a sufficiently clear area of the
windshield in low-speed flight or
during surface operations. Alternatively,
airflow over the windshield may be
disturbed during such critical times as
the approach to land, where the airplane
is at a higher-than-normal pitch attitude.
In these cases, areas of airflow
disturbance or separation on the
windshield could cause failure to
maintain a clear-vision area on the
windshield.
Applicability
As discussed above, these special
conditions are applicable to the Model
LJ–200–1A10 airplane. Should Learjet
Inc. apply at a later date for a change to
the type certificate to include other type
designs incorporating the same novel or
unusual design feature, the special

14OCP1
63852

conditions would apply to that model as
well.
Conclusion
This action affects only certain novel
or unusual design features on the Model
LJ–200–1A10 airplane. It is not a rule of
general applicability.

The Proposed Special Conditions
Accordingly, the Federal Aviation
Administration (FAA) proposes the
following special conditions as part of
the type-certification basis for Learjet
Inc. Model LJ–200–1A10 airplanes.
The airplane must have a means to
maintain a clear portion of the
windshield, during precipitation
conditions, enough for both pilots to
have a sufficiently extensive view along
the ground or flight path in normal taxi
and flight attitudes of the airplane. This
means must be designed to function,
without continuous attention on the
part of the crew, in conditions from
light misting precipitation to heavy rain,
at speeds from fully stopped in still air,
to 1.5 VSR1 with lift and drag devices
retracted.

Jkt 226001
Section 105(e) of the Federal Alcohol
Administration Act (FAA Act), 27
U.S.C. 205(e), authorizes the Secretary
of the Treasury to prescribe regulations
for the labeling of wine, distilled spirits,
and malt beverages. The FAA Act
provides that these regulations should,
among other things, prohibit consumer
deception and the use of misleading
statements on labels, and ensure that
PO 00000

Sfmt 4702
labels provide the consumer with
adequate information as to the identity
and quality of the product. The Alcohol
and Tobacco Tax and Trade Bureau
(TTB) administers the regulations
promulgated under the FAA Act.
Part 4 of the TTB regulations (27 CFR
part 4) allows the establishment of
definitive viticultural areas and the use
of their names as appellations of origin
on wine labels and in wine
advertisements. Part 9 of the TTB
regulations (27 CFR part 9) sets forth
standards for the preparation and
submission of petitions for the
establishment or modification of
American viticultural areas and lists the
approved American viticultural areas.
Definition
Section 4.25(e)(1)(i) of the TTB
regulations (27 CFR 4.25(e)(1)(i)) defines
a viticultural area for American wine as
a delimited grape-growing region having
distinguishing features as described in
part 9 of the regulations and a name and
a delineated boundary as established in
part 9 of the regulations. These
designations allow vintners and
consumers to attribute a given quality,
reputation, or other characteristic of a
wine made from grapes grown in an area
to its geographic origin. The
establishment of viticultural areas
allows vintners to describe more
accurately the origin of their wines to
consumers and helps consumers to
identify wines they may purchase.
Establishment of a viticultural area is
neither an approval nor an endorsement
by TTB of the wine produced in that
area.
Requirements
Section 4.25(e)(2) of the TTB
regulations outlines the procedure for
proposing an American viticultural area
and provides that any interested party
may petition TTB to establish a grapegrowing region as a viticultural area.
Section 9.12 of the TTB regulations (27
CFR 9.12) prescribes standards for
petitions for the establishment or
modification of American viticultural
areas. Such petitions must include the
following:
• Evidence that the area within the
proposed viticultural area boundary is
nationally or locally known by the
viticultural area name specified in the
petition;
• An explanation of the basis for
defining the boundary of the proposed
viticultural area;
• A narrative description of the
features of the proposed viticultural area
that affect viticulture, such as climate,
geology, soils, physical features, and
elevation, that make the proposed
