Phoned them and had a chat...The AC has 11 hours left on it before its 100hr, so the oil is expected to be black....which is understandable....(although running with low oil will make it turn black quicker!)
He suspects that the previous pilot didnt check the oil, because "its a self fly hire machine, people just jump in and go"
....if thats the attitude of some of the pilots there, im not so sure I want to continue using these aircraft!
He did rather reluctantly agree to look into it tomorow though which is nice of him
Am I blowing this out of proportion?....Should I just have topped up the oil and forgotten about it?
