What type of jumpers are normally used to bond noncontinuous stainless steel aircraft components?

The correct answer is that stainless steel jumpers are typically used to bond noncontinuous stainless steel aircraft components. This is crucial for ensuring effective electrical conductivity and maintaining structural integrity. Stainless steel jumpers provide a reliable connection that prevents galvanic corrosion, which can occur when dissimilar metals are in contact.

In applications where components are made of stainless steel, using stainless steel jumpers matches the material properties and reduces the risk of corrosion, promoting longer service life and reliability of the electrical system. The physical and chemical properties of stainless steel, including its resistance to corrosion, make it an appropriate choice for bonding such components.

The other options, while they may provide conductivity, introduce potential complications or are not appropriate for this specific application due to differing material properties. For instance, aluminum and copper jumpers could lead to galvanic corrosion when used with stainless steel components, and steel jumpers may not offer the same resistance to corrosion as stainless steel. Therefore, the use of stainless steel jumpers is the preferred and most reliable choice for bonding noncontinuous stainless steel aircraft components.
