  1. +@BruceBerry-g4b The aircraft was completed in 2009. There was a new requirement that all planes made after March 2010 should have independent power for the flight recorders. The new speculation is possibly some major electrical failure since comms, transponder, and flight recorders stopped at roughly the same time.
