Similar happening at Mesa a few years ago. Aircraft had been written up 3 times in two days for "continuous illumination of low oil pressure warning light," all on the same engine. In the QRH, that light requires us to shut down the engine.

Airplane is given to us to operate as a revenue flight to MX base. Destination is IFR, icing en-route. I expressed my feelings to the CA (I was against accepting the airplane). CA wanted to go home, vs. deny-ing the airplane and overnight out of base (last leg of 3 day trip).

We went, the light stayed off, and we lived to see another day. Most uncomfortable flight of my career.

It was legal, but in my opinion, wrong to operate that flight as revenue. I didn't want to go either way, but I wanted to go even less with 50 people in back.
