'airport' is the definition.
(thesaurus)

'crash on network' is the wordplay.
'crash' becomes 'ding' (I am not sure about this - if you are sure you should believe this answer much more).
'on' says to put letters next to each other.
'network' becomes 'LAN' (Local Area Network).
'ding' after 'lan' is 'LANDING'.

'activity created by minor' acts as a link.
This may not be correct. Some or all of it may be part of another bit of the clue.

Can you help me to learn more?
