The Bell 430 has a fuel capacity of 935 liters (247 U.S. Gallons). Fuel is contained in
five interconnected cells, located near the helicopters' center of gravity to eliminate
the need for fuel management. Gravity transfers fuel between the cells automatically,
eliminating the need for transfer pumps. The three cells contained within the fuselage
are enclosed by structural panels which form the rear seat base, internal bulkheads,
and the outer skin. The two outboard (wing mounted) cells are surrounded by fiberglass
panels and aluminum alloy skin. Interconnect and vent lines between the wing cells
and those in the fuselage are designed to break-away and self-seal to prevent fuel
spillage should the wing become separated from the fuselage, while those fuel lines
within the fuselage are designed to stretch up to 50%. Each fuel compartment is lined
with a flexible bladder constructed of a multilayered sandwich-type lamination of rubber,
cement, nylon, and woven fabric. All cells have met rupture resistant standards by
being drop-tested from 15 meters (50 feet) while 75% full with no subsequent leakage.
The E 1622-2 cell liner material features a 16 gauge gum rubber inner liner and a high
strength 0.5 kg/m
2
(15 oz/yd
2
) rubberized fabric outer ply for tear and puncture resistance.
