Thinking from an examiner standpoint.
There are two phases here: approach and landing.
So where does the approach end and the landing phase begin? For a NPA, the approach ends the moment you leave the MDA for the field, or once you reach the MAP - which is where the missed approach segment starts. For a precision approach or APV, the approach ends once you reach DA(H) - the landing starts if you're visual at that point or the missed approach segment starts at DA(H) with no contact.
