ClaimOfficial finding
Communications were more likely switched off or unpowered than randomly failed
ACARS, transponder and VHF drop together near IGARI. The report favours manual off / power interrupt, without proving intent.
Absence of 7700/7600/7500 squawk is part of this picture. A novel failure mode is not eliminated.
