SOUNDPROOFING
A highly effective soundproofing installation has been engineered for the Bell 430,
and is provided at no additional cost, unless the customer declines its installation.
This provides the customer flexibility where non-Bell interior completions are planned,
or utility operations require the minimum aircraft empty weight / maximum available
payload. The Basic Soundproofing Installation reduces the noise entering the cabin
from the engine and transmission compartments. The soundproofing material consists
of a heavy duty blanket which fits between the headliner and interior trim panels, and
the airframe. The blanket is constructed from alternating layers of sound-attenuating
composite foam, lead foil, and vinyl covered fiberglass batting. Access panels and
bulkhead passages for wiring, ducting, and plumbing are sealed to eliminate extraneous
sound paths.
The installation is compatible with only the STANDARD INTERIOR TRIM. The installation
is not compatible with the optional CORPORATE INTERIOR TRIM or with highly
customized interior completions (such as "COCOON" isolation-type interiors).
The increase in weight with the soundproofing installed is 43.0 kilograms (95.0 pounds).
If the optional auxiliary fuel tank is also installed, the weight increase is 43.2 kilograms
(95.3 pounds).
STANDARD SOUNDPROOFING BEHIND INTERIOR TRIM PANELS REDUCES
NOISE IN THE CABIN FROM THE ENGINES AND TRANSMISSION
[SOUNDPROOFING WEIGHT IS NOT INCLUDED
IN THE STANDARD CONFIGURATION WEIGHT]
