Flight records prior to takeoff indicated multiple deferred maintenance
items, including a logged defect in the Stabiliser Position Transducer
(“STAB POS XDCR”), which controls pitch signals. More critically,
flight data captured around 07:53 UTC recorded “Bus Power Control
Unit (BPCU) gateway operation faults” on both the left and right sides.
BPCUs are central to the 787’s electrical and data distribution
network, and a gateway fault suggests the inability to correctly
transmit or receive control signals, including the “RUN” command to
the Full Authority Digital Engine Control (FADEC). These findings
strongly support the “electrical disturbance theory,”
