CHIP CAS warning

[haeriphos]

I was cruising along at 17,000 this evening and got a warning indicator: CHIP. I looked in the POH and it appears to be a fault with the oil system. I was in the middle of the green for temp and at the upper end of green for PSI (123) so I reduced torque and continued along my trip as I wasn't too far from my destination. No other problems, landed fine, and opened up the maintenance manager. Everything is green but I do notice that my oil is "straw colored" but still has a green background. I have just under 50 hours on the engine, not using accelerated wear. 

So my question is, do I need to change the oil at this point? Does this message indicate something else is wrong? As I do not hold an A&P I'm just relying on things to be yellow or red in the maintenance manager before I replace/repair them. I am running 1.0.8 but planning on updating to 1.1 soon. 

 

Thanks!

Hi,

the CHIP sensor detects small metal parts/shavings in the oil.

The reason for the metal parts is normally wear of mechanical parts, e.g. the bearings.

So if you get the chip message, either some other parts should show heavy wear, or maybe the sensor itslelf is defect ;)

Interesting. I'll keep an eye on it after I update to 1.1. When I landed everything was in the green, nothing suggesting any part was breaking down.

What i desribed is the "real life" functionality of this sensor.

I´m not sure, if the simulation is so detailed, to set a chip detection error only if some other mechanical wear is really high.
