Hi all,
Today I had a low oil pressure warning go off about 10 minutes into my flight while doing light airwork. I performed the annual at the end of September and the oil filter and screen were clean at that time. I have been out of town a lot on business, so have been unable to fly for about 6 weeks... so this was a -rust remover- flight for me. (hopefully not engine rust! )
I returned immediately to the airport while getting a code to stay high through Ottawa's Class C to get back to Carp for a straight in to our active. All was OK.
This has happened to me once before after an oil change and a long period of inactivity on the plane (2 years ago) The last time this happened, I drained the new oil and inspected the filter and screen for debris and found none. I removed the Vernatherm and inspected it, and could not find anything suspicious there either. I buttoned it back up, test flew it, and all was OK, and has been fine until now.
Other than repeating the steps I did in 2012, should I be looking elsewhere for the cause?
The oil pressure reading would drop to 20-23 PSI at 2400 RPM, then return to normal for a while, then drop again. It ran at 85-90 PSI at 1800 RPM once I was back in front of my hanger. I haven't pulled the engine log yet, but will look at that later this week.
Any suggestions would be welcome.
Thanks,
Chris
