Following the last month’s explosion that knocked offline Foxconn’s iPad 2 assembly facility in Chengdu, China and left three killed and at least fifteen injured, the news is reaching us that the assembly line has resumed operation. John Paczkowski on the All Things D blog relays this tidbit from a Ticonderoga Securities analyst Brian White’s note:

Foxconn has concluded investigation into the explosion, but has yet to release any results, Paczkowski says. The explosion may have cost Apple anywhere between half a million iPads up to a third of total iPad 2 output.
