FOD prevention vs HUMS

Two critical aspects of aviation and rotorcraft safety are Foreign Object Debris (FOD) prevention and Health and Usage Monitoring Systems (HUMS).

HUMS detects early signs of wear and tear by continuously monitoring, collecting and analyzing data from various sensors on turbine engines and drive train components. Sensors will pick up vibration levels from the components. Prognostic algorithms create and establishes a baseline of normal operation. If the HUMS detects wear by increased vibration levels, it will alert the operator. Read more here

This proactive approach allows maintenance crews to address issues before they escalate, preventing unexpected failures and enhancing overall aircraft safety. The data collected by HUMS also facilitates predictive maintenance, optimizing maintenance schedules and reducing downtime.
HUMS can accurately pinpoint abnormal wear down to the inner or out race of a bearing.

GPMS offers an aftermarket next generation, predictive HUMS designed to give rotorcraft operators the power to “Know it before it matters.” Its flagship Foresight™ solution provides Machine Condition Monitoring, Rotor Track and Balance and Helicopter Flight Data Monitoring.

The only downside about HUMS is that it will alert you, when the component damage has already been done.

It is the responsibility of the operator, pilots and maintenance crew to make sure the turbine oil system is not contaminated during oil filling and maintenance actions. Read more about “Prevention is the best way to avoid FOD in turbine engine oil systems.”
