A.24: Here is an example of a fuel pump for an aircraft. In the first example, the fuel pump is considered ‘equivalent.’ In the second example, it is not considered ‘equivalent.’

Example 1

(Meets the ‘equivalent’ standard): A fuel pump used in AT-only controlled aircraft in "production" is modified for use in a military aircraft. The fuel pump has the same function, performance capabilities, but needed to be modified solely for fit purposes (to fit in an area of a military aircraft). No other changes to the fuel pump were made, such as for fuel flow.

Example 2

(Does NOT meet the ‘equivalent’ standard): A fuel pump used in AT-only aircraft in "production" is modified for use in a military aircraft. However, in addition to modifying the fuel pump for fit purposes (to fit in an area of a military aircraft), the fuel pump has been made of higher strength materials to allow it to pump at a higher pressure.
