Health & Usage Monitoring System (HUMS)
SB number : EC155-45-60-02 (R00)
Applicable to version(s) : B, B1
The Health Usage Monitoring System (HUMS) records the status of critical systems and components on your helicopter. The objective is to detect at an early stage progressive defects.
The HUMS system is using sensors installed throughout the airframe. This material is linked to a central computer unit with a data recording and storage system. This is allowing the support to identify if the helicopter is likely to develop faults that would need an intervention. This system is monitoring the health of all significant vibrating and spinning parts such as engines, gearboxes, shafts, fans, rotor systems etc. Thanks to the record of all of these data, the maintenance of the helicopter can be proactively performed.
