Answer

"Not only .. but also" are used correctly, but you have some issues a couple of  words.

"Stability" instead of "stable". Stability is the noun that is the object of the verb maintain. Stable is an adjective when used in this sense.

"Needs" instead of "need". The subject of the sentence is "the ability", singular, so we need the matching verb form.
