What are the bump outs on a Bell 430 helicopter for? On a Bell 430 helicopter, you'll see what look like short wings on the side. I've seen people fueling in them, so I assume they are fuel tanks, but do they serve another purpose? Do they have a name?
They are called sponsons and act as enclosures for the retractable main landing gear.  The 430's ancestor, the Bell 222, was equipped with the same fairings.
