Not necessarily so. The Eurocopter SA365N series as standard have no indicating mag plugs or fuzz burners for the transmissions. They have a mag plug quick disconnect for the MRGB and the TRGB. A mag plug which requires tools to remove it for the mast.
I believe the BO105 had an indicating system for the MRGB but it was removed on UK aircraft because of the high number of spurious warnings!!!!

I pull mag plugs on a daily basis and as part of a sceduled maintenance program. I've yet to pull one specifically as the result of a HUMS report.
In truth in this case it could be either. However there is no mention of a HUMS issue before the accident in the AAIB report. I would have thought it would get a mention.
