Probable cause
The windshield failed due to arcing from an inadequate solder connection at the anti-ice power terminal block.
NTSB analysis
The arcing/overheating of the braid wire caused the fire event in the cockpit. Removal of the terminal block and sealant revealed an arcing hot spot where the failure occurred at power braid wire position A. There was no visible solder at the connection point of braid wire A, which led to the arcing of the power braid wire and the fire event in the cockpit.
