Hello,

Am trying to locate a round, 3 in 1 gage (Oil pressure, oil temp, fuel pressure) for an Aero Commander 680 FLP. The old one has a loose glass face and it's affecting the working of the oil temp indicator needle. (The gage is also susect to erroneous readings for oil temp even when it's not affected by the glass) I know where I can send it out to be rebuilt (they don't have an up and ready gage) but the down time is 10-15 days. Part number is: 273-7TN12. Anybody got one reasonably priced?

I wrote a while back about two hydraulic lines that broke within two hours flying time of each other. There were lots of email here about hydraulic lines, many gave me some good things to think about. Just for everyone's information, here's the story on both lines. The first was a very short line in the left wheel well that connected the aux pump pressure switch to the aux system. It broke at the flange. It's been replaced. The second line had a fine corrosion leak and that line's purpose was to retract the gear. That line was about 51" long and ran between the right engine nacelle (left side) and through the wing section between the right engine and the fuselage. I haven't seen the line yet but that's what the A&P folks tell me. It's been replaced and pressure checked OK. Maintenance said the other lines throughout the area look OK. Test flight Friday.

Am going to have maintenance spray some corrosion preventive stuff throughtout the plane soon. Does that stuff work?

Just wanted to fill in the info related to my hydraulic problem. All seems OK there now. I'm getting good at using the nitrogen system for gear extension...2X in 3 flights.

Not sure who mentioned it to me, but I'm pulling the aux pump circuit break after lift off from now on. Did so the last flight and the brakes, flaps and steering worked. Not sure if that's the reason, but the way the system's set up it sure makes sense.

Thanks,
