Was the airframe involved in the LOT Flight 16 accident repaired?
From Wikipedia:


  The damage to the plane was so extensive that the airline chose not to make repairs. The aircraft was scrapped in November 2013.


I can't find information on the figures, but for Qantas Flight 32 the figure to repair it was ~$145 million.

Nowadays you can buy a used 777 for 2% of its list price. A fraction of the $145m figure above to fix an A380.

New 777 is 277.3 million, used is 7.7 million.

I hope that helps.

So cost of repair, age of aircraft, cost of adding a used plane to the fleet instead, etc.
