That’s a new one…oil pressure wild fluctuations

[phxcobraz]

Pretty sure the sensor is bad. It was all over the place taxing after startup. Totally stable at normal numbers during runup and then in flight. Been trying to chase a small oil leak lately and wondering if maybe the sensor is at fault or near something that is. Have drips down the firewall and nose gear.

Depending on how the sensor works that could be a ground issue or a connector issue.

I think I saw you taxi to the runup pad.   I was on the south side chasing radio signals around.

Nice! I heard an ELT go off for a long time while I was north of the airport taking photos of an ultra-marathon on Black Canyon trail. Same thing?

Yea I’m in for annual next month and we can chase the wiring/connectors. @Robert Hicks is doing some G5s, PAR200B, and a new panel, so we’re going to have it pulled apart anyway. 
The oil leak seems like it’s either the oil filter(challenger with new oring), filter adapter gasket, a mag, or prop governor as they are all in that area.

Might have been us, but maybe not.    We were using a 406 MHz beacon but it may have also had a 121.5 MHz component.    Usually if we're doing stuff for VHF the test/practice beacons are actually on a different frequency so that they don't interfere with 121.5, (but they do interfere with DVT Ground, as we found out last time...oops).    We have to get permission to use the 406 thingie, so I'd never used it before.  I'm not completely sure what it does in VHF, if anything.

Usually in the Phoenix area if there's a 121.5 MHz signal it's almost always the salvage yard by Sky Harbor threw something in a dumpster or dropped it off a shelf or something.
