If it wasn't for AIS which is an optional fitment and not for safety of flight you would possibly STILL be looking for this aircraft.
ADELT didn't work.
ELT didn't work and not possible underwater anyway.
Radar track - outside coverage?
I may have missed something?
Something to think about for the future.
Missed the operators own flight following system. CHC certainly had this fitted to the SAR cabs. It will have had a higher sample rate than AIS and is GPS/Satcomm based rather than the VHF line of sight of AIS. CHC used to use Skytrac, not sure if they still do. Obviously won't have heard much of this as the data will be password protected and not in the public domain.
