Unsafe Condition
Poor or no continuity between the insert and the chip detector housing on certain chip detectors, part numbers B3188B and B4093, could result in no chip indication when the chip detector has been bridged by metal particles, potentially leading to failure of a chip detector indication, loss of a critical component, and subsequent loss of control of the helicopter.
