What value is data when ignored?
As mentioned earlier two bad events occurred post detection by HUMS equipped aircraft, yet each aircraft was signed off as "Serviceable".
As a perfect helicopter is impossible to design,build, and maintain...there needs to be a detection system to assist in ensuring faults being found and reported ergo HUMS being invented and incorporated into modern Helicopters.
What good is HUMS if its successful detection of a problem is not properly used in a timely fashion?
Half assed measures undo every Safety Program.
HUMS alone is not the last word on the airworthiness of an aircraft but it sure goes a long way in making such a determination.
Why can HUMS not be modified to provide a Cockpit warning of some kind should a fault situation be detected?
Why can the ground station not be modified so that n immediate fault message not be provided in real time to Engineering?
If airlines can live stream engineering data the it would seem the helicopter industry could do the same in specialized operations such as the North Sea and Gulf of Mexico?
Yes....that costs money....probably a lot of money....but at what point does those costs are offset by preventing aircraft losses that kill a dozen or more people per event?
