"It is a small airport."

Translation: Det er en lille lufthavn.

Why can't I use små here?

[Xneb]

Lufthavn is singular here, and "små" can only be used to describe plural objects, for example:
Jeg har en lille kat => Jeg har små katte
Det lille hus ved kysten => De små huse ved kysten

Also want to know why Det and not Den?

[BrunnoHC]

Because "det" is neutral, I guess
