AAIB Oct 2016
Bell 206B Jet Ranger II, G-OAMI.
Having departed Wycombe Air Park and in level flight, the helicopter suffered a rapid and uncommanded loss of altitude. The pilot, believing that there had been a loss of engine power, carried out an autorotation. The helicopter touched down with a high rate of descent which resulted in the failure of the tail boom and landing gear.
Data recorded by on-board systems showed that the engine operated normally throughout the event. A limited examination of the helicopter was unable to identify a defect within the engine or flying controls which might have caused the uncommanded loss of altitude.

Indicating systems
On board systems could simply be interpreted as go pro perhaps.
Whilst it's not an approved aircraft fit piece of equipment it can provide a picture that can paint a thousand words as well as giving a soundtrack.

another reason in favour of simplex
if a pilot can get confused to the point of crashing a perfectly serviceable machine just imagine how confused he might be if it were more complex? (as we see from time to time)
(another reason for singles, eg Kenya)

Hi 212Man - that's a fuel flow transducer and fuel management computer not a HUMS monitoring and recording system.
It does state that their fuel monitor does support their ETM though:
ETM - Helicopter
And the ETM claims Allison 250 support!
However doesn't mention any STCs?
