Isn't that the truth? Some people say dogs are color blind, but ours can see the color of cheese through walls.

JHC,
Wrong! Our golden doodle went blind 6 months ago at 7 years old and she can still “see” that cheese, meat, bread through and around walls.... she likes fresh water in her bowl and will sniff disapprovingly if it’s more than 10 hours old.

I've got a mutt that turns up her nose at the well water we give them (which to us humans is quite a bit nicer than the tap water our neighbors drink). But she'll go outside and drink from the flower pot that fills from roof runoff (dirty metal roof and clay/peat mix in the pot), or the water that pools on the driveway after a storm.

The other dog (Mini-Schnauzer) is the one who meets you at the refrigerator door when you even THINK about getting out a piece of string cheese... Darn dog is smarter than we are!

String cheese is Labrador heroin.

Ran into an interesting problem this weekend with the 182. Last night we had a squall line pass through Lake Havasu City at around 10:30 pm and it rained sideways and we had 50 knot winds for a couple of hours. I'm glad I had the control lock installed! When I went to leave this morning the airplane had been hopping around in the wind and slipped the chocks somewhat and the tie down chains were tight enough I couldn't get them off without moving the airplane a little. When I finally moved it I noticed a small amount of water drip out of the tail cone area onto the ground and didn't think much of it.

We flew home and when I was putting the airplane back in the hangar I noticed more water spots on the concrete from the tail cone. I walked over to my I/A's hangar and asked him to look at it with me. He said there should be a drain hole near the tie down ring and there were some drain holes but they are not directly on the bottom and were probably an inch or two up on each side. He said to use a #40 drill and make a drain hole just in front of the aft bulkhead which I did. As soon as the drill broke through I drained out about two beer cans of water that had accumulated in the tail from the rain last night. I suspect it all leaked in from around the tail fairing. All of the other drain holes on the bottom of the fuselage were clear so I'm curious why Cessna didn't put a drain hole near the tie down ring by the aft bulkhead.

Dave.

There should be two drain holes aft of the next bulkhead forward. I think in a normal attitude, water should flow forward but I’m going from memory, sitting at my kitchen table.

My friend has a C-182 RG. Next time his hangar door is open, I'll take a photo.

That's exactly correct. I took a look at a friend's C-182RG yesterday and his was how you said. Sitting on the ground, the slope of the fuselage bottom was probably 10 degrees toward the front. In this photo, the access panel is toward the front and the drain holes are toward the aft. (Ignore the file name. Coffee hasn't kicked in yet.)

Get out the drill!

So, this is the second annual I've been through on the 182M since I purchased it in 2018. So far no surprises and we're in the the process of getting it all buttoned up. But in the mean time I had a master solenoid go bad about a month ago and had to install a new one. In the process of doing that I was told be several mechanics that Cessna recommends in a SB to install diodes on the master and starter relay solenoids to prevent arcing in the switches which lead to premature wear and failure. I found a great video by Cessna which demonstrated the internal switch arcing and I was shocked at just how much it was. So, last night I made up the diode jumpers with 1N5400 diodes and clear shrink tubing to see the diode band and installed them. Just didn't know if any of the other Cessna 182 folks that have older aircraft knew about this or already have them installed but thought I'd share.

Here's the video from Cessna...

Here's my diode installation.

Dave,

Thanks for posting the Cessna video.

Thank you, I now have clean firewall envy.

Seriously, got a cite for the SB? I am certain my 182M does not have those diodes in place.

Richard,
Here's one that covers the ignition switch on later models and the installation of a diode on the starter relay.

Not exactly covering the master relay diode but it's a good idea to install one there as well as you can see by the video. Without the diode you not only run the risk of premature contact failure in the master switch but also run the risk of damaging avionics with high voltage spikes if you inadvertently leave the avionics switch on and shut down the power with the master switch.

Here's another good video that explains why you should run a diode on relays.
