Fleetwood Enterprises, Inc.; Receipt of Application for Decision
of Inconsequential Noncompliance
Fleetwood Enterprises, Inc. (Fleetwood) of Riverside, California
has determined that front side windows of some of the motor homes it
manufactured fail to comply with the light transmittance requirements
of 49 CFR 571.205, Federal Motor Vehicle Safety Standard (FMVSS) No.
205, ``Glazing Materials,'' and has filed an appropriate report
pursuant to 49 CFR Part 573, ``Defect and Noncompliance Reports.''
Fleetwood has also applied to be exempted from the notification and
remedy requirements of 49 U.S.C. Chapter 301--``Motor Vehicle Safety''
on the basis that the noncompliance is inconsequential to motor vehicle
safety.
This notice of receipt of an application is published under 49
U.S.C. 30118 and 30120 and does not represent any agency decision or
other exercise of judgment concerning the merits of the application.
Standard No. 205, which incorporates by reference, the American
National Standards Institute's (ANSI) ``Safety Code for Safety Glazing
Materials for Glazing Motor Vehicles Operating on Land Highways'' Z-
26.1-1977, January 26, 1977, as supplemented by Z26.1a, July 3, 1980
(ANS Z26.1), specifies that glazing materials used in windshields and
in windows to the immediate right and left of the driver of trucks and
buses shall have a luminous transmittance of not less than 70 percent
of the light, at normal incidence, when measured in accordance with
``Light Transmittance, Test 2'' of ANSI Z-26.1-1980. It specifies that
all windows of an automobile shall have a luminous transmittance of not
less than 70 percent.
During the period of July, 1995 through January, 1997, Fleetwood
[[Page 32677]]
manufactured approximately 1,438 1996 and 1997 model year Flair brand
motor homes having front side windows with a luminous transmittance of
62 percent and approximately 188 Bounder brand motor homes and 733
Discovery brand motor homes, also of model years 1996 and 1997, having
double panes of the same glazing in the front side windows. Fleetwood
reported a luminous transmittance of 41 percent for the dual pane
application. Beginning with vehicle production in January, 1997, front
side windows with a luminous transmittance of greater than 70 percent
have been installed in all Fleetwood motor homes.
Fleetwood supports its application for inconsequential
noncompliance with the following:
Fleetwood considered a Ford Motor Company inconsequentiality
petition that references computer modeling studies and in-car
evaluations conducted by Ford Motor Company that were used in their
petition dated February 6, 1995 which showed a 5 point reduction in the
percentage of light transmission, from 65 to 60 percent, resulted in a
reduction of seeing distance of only 1 to 2 percent during night time
driving, and little or no reduction in seeing distance during dusk and
daytime driving. Based on these studies, the subject Flair brand motor
home driver and passenger side windows with 62 percent light
transmittance would be expected to result in no significant reduction
in seeing distance during night time driving and virtually no reduction
during dusk and daytime driving, compared to glass with a 70 percent
transmittance. Reductions in seeing distances of 1 percent or less have
no practical or perceivable effect on driver visibility based on
observer's reports in vehicle evaluations by Ford of windshields with
line-of-sight transmittance in the 60 to 65 percent range. The subject
Bounder and Discovery brand motor home driver and passenger side
windows with 41 percent light transmittance would be expected to result
in no significant reduction in seeing distances during night time
driving, and little to no reduction in seeing distance during dusk and
daytime driving.
Fleetwood also considered that the stated purpose of FMVSS No. 205
to which the light transmittance requirements are directed is ``to
ensure a necessary degree of transparency in motor vehicle windows for
driver visibility.'' NHTSA, in its March, 1991 ``Report to Congress on
Tinting of Motor Vehicle Windows'', concluded that the light
transmittance of windows of the then new passenger cars and vans that
complied with Standard No. 205 did not present an unreasonable risk of
accident occurrence. The new passenger cars and vans that were
considered to not present an unreasonable risk had effective line-of-
sight light transmittances through the windshields as low as
approximately 63 percent on passenger car windshields and 55 percent on
van windshields (as determined by a 1990 agency survey, the results of
which were included in the Report to Congress). Fleetwood feels that
while light transmittance and driver visibility through front side
windows is important to the safe operation of motor homes, it is not as
important as driver visibility through motor home windshields.
Therefore, while the use of front side window glazing with luminous
transmittance less than 70 percent is technically a non-compliance, we
believe the condition presents no risk to motor vehicle safety.
Fleetwood's opinion that this non-compliance is not safety related
is also based upon the consideration of the great amount of visibility
that is inherent in the driver packaging of the subject motor homes.
Factors which contribute to this visibility are:
1. The windshield glass is approximately 100 inches wide by 36
inches tall.
2. The windshield glass is installed at an incidence angle of 4
degrees back from vertical.
3. The involved side window glass on the Flair and Bounder brand
motor homes is approximately 46 inches long by 31 inches tall. The
involved side window glass on the Discovery brand motor home is
approximately 52 inches long by 34 inches tall.
4. The involved side window glass is flat and is installed
perpendicular to the ground.
5. The driver' s seat H point ranges from approximately 50 to 62
inches from the ground.
6. The involved windows have a slider feature which allows them to
be positioned out of line of sight (if desired), and
7. Side window visibility is primarily key in sharp turning
maneuvers which are typically performed at low speeds.
Interested persons are invited to submit written data, views, and
arguments on the application of Fleetwood, described above. Comments
should refer to the docket number and be submitted to: Docket Section,
National Highway Traffic Safety Administration, Room 5109, 400 Seventh
Street, SW., Washington, DC 20590. It is requested but not required
that six copies be submitted. All comments received before the close of
business on the closing date indicated below will be considered. The
application and supporting materials, and all comments received after
the closing date will also be filed and will be considered to the
extent possible. When the application is granted or denied, the notice
will be published in the Federal Register pursuant to the authority
indicated below.
Comment closing date: (July 16, 1997).
