CHIP DETECTOR SYSTEM
The chip detector system is described in the Ch.63-00-00. On the Tail Rotor
Drive System there are two chip detectors: one chip detector is installed on
the IGB and one chip detector is installed on the TGB.
When the IGB CHIP or the TGB CHIP caution messages are displayed in
the CAS window of the MFD, the pilot can try to burn the ferrous particle(s)
pushing the CHIP BURNER switch located on the MISC control panel.
If the burning is successful the particle is classified as “small” and the
relevant caution extinguishes.
In the opposite case, the particle is considered “large” and cannot be
burned.
When the particle is burned, a message is written in the Non Volatile
Memory (NVM) for maintenance purposes.
