Pat and Ed were correct with their their PIREPs. I took the entire right side lower panel off the radar unit and all was there in plain view. All it required was a good briefing. Sure enough, the fluid was down about 1 teaspoon (glad I bought a gallon...). Still above the line but... Not bad for a 40 year old aircraft with 25 hours of recent hard training flights (at least) since last this was looked at.

Now that I know what to look for and where I think I will be able to get to it from the small side access panel. I took the advice and tied a little rope around the dipstick as it would be all too easy to ruin your day by dropping it in the sump. Helps to find the bloody thing in tight quarters too..!

Here are some photos... Note the safety rope.

Thanks for the help guys!
