What octane was in your flying flask. Did its contents contribute to the emergency?
Ya survived one of them 'guy just bought the plane' incidents. And ya greased it. Sumpin about situations that got your concentration on steroids often lead to those. In my experience anyway. Anyway, good job. Ya know, if ya got a Cessna you wouldn't have to do all that thinkin bout gettin the Tower to have a look at the gear.First flight with my wife in our "new" Comanche and we got to do an emergency landing.
Pilot error of course.
We took off and flew and she loved the plane for the first 20 minutes.
Everything was great then the GPS went black. My first thought was turn the avionics off and back on. But it was still blank. I spent about 30 seconds irritated because I just bought this and surely this cannot be the first time the GPS has gone out. The seller must have known it was dying and didn't mention it. So my first emotion in all of this was anger.
Then the radios started dimming and I said "Crap we've lost the alternator".
As I reached over to squawk 7600, the transponder went bank.
Embarrassingly, that's the first time I noticed the ALT light was illuminated and started to ponder if the light being on meant the ALT was on or it was failing.
Everything switched to slow motion as I simultaneously thought about the electric landing gear and reached at the switches to start powering everything off.
No radios, transponder, GPS, and I am guessing landing gear was going to be an issue.
Fly the plane. So I made sure everything flight-wise was fine and told my wife to grab the stratus out of my flight bag since we were nordo and I want to be able to see traffic.
I climb up a few thousand feet, slow way down and try to lower the landing gear. It goes down about a quarter of the way and stops.
Eren is starting to panic, cry, and pray. I am trying to reassure her that there is no reason to panic, the plane doesn't need electricity to fly. I give her work to do "Look for traffic" so I can troubleshoot.
I have obviously lost my alternator I am thinking but then I start to think about every plane I have ever flown and that all of them have Alternator field switches. I am scanning every square inch of the panel over and over looking for ANYTHING that looks like an alternator switch. I don't see anything.
I grab 2 checklists that came with the plane looking for any mention of turning on or ensuring the alternator switch is on and I find nothing.
Now it is time to do what both instructors I flew with told me. slow down to 100, open the panel on the floor, read the instructions on the back of it, lift the red lip, extend the pole, push it to the stop.
It is full forward but no green light on the panel.
Here's where I got dumb brain. I said "I'm going to fly by the nearest controlled field and ask if I can do a low pass and have them look.... Oh yeah, no radio. We're on our own here.
I recall the seller of the plane stating at night, when the panel lights are on, the green light either doesn't come on or is very dim. I found the knob and it was on but on its dimmest setting. 1mm to the left and click. Green light comes on. The gear is down and locked.
We head to our home field and feel horrible because there is traffic in the pattern and of course none of them can see me on ADS-B or hear me so I probably irritated some of them.
We cross the numbers and I am just waiting to hear metal scraping but I greased the landing.
Not so much as a bump. We taxied to the hangar to put the plane away and all was well.
We arrived in 2 separate cars so my wife went back to the house and I went through that plane again and I saw a label "Alt Field" on the front of the panel but no switch for it.
I felt under the panel where the circuit breakers are and sure enough right in the middle of the circuit breakers is a toggle switch. I believe when I was feeling the breakers before taking off, I inadvertently hit that toggle and turned the alternator off.
Lucky for me it turns out I have an A&P on my field that is very familiar with these planes. He came over, jacked the plane up and re attached the landing gear transmission. On the Comanche when you do the manual procedure, it detaches the gear mechanism from the jackscrew that drives it up and down so that has to be manually reattached after manual extension.
My wife is totally cool now and has no concerns about the plane or flying in it. She said she actually has more confidence flying because she saw me stay collected while this was going on . She said "I have never heard the business voice before and gotten that much eye contact as you explained what was happening and what wasn't happening and what you were going to do about it"
I called the former owner and just asked about it and he said "It never crossed my mind to mention that switch" It was just part of his muscle memory.
So I guess there is some silver lining. But yes, complete pilot error. I am making my own checklist that references the alternator switch even though, I know I will never forget it again.
I am also having it relocated to a less ridiculous location.
I have also relabeled the "Alt" light to "ALT INOP"

There are phone numbers for ATC in foreflight, calling one of them would probably also be an option.
Having been to that airport, dealing with the other tenants may be the most hazardous part....We head to our home field and feel horrible because there is traffic in the pattern and of course none of them can see me on ADS-B or hear me so I probably irritated some of them.
For your USB charger in the cigarette lighter, you might want to consider something like this to confirm the battery is charging as part of your runup procedures (of course until you get a full glass panel that includes this). And by the way, get rid of all that bright red string around your yoke -- that can be a hazard.
Hahahaha.
You're not wrong.
If I make a video about, I will be "lucky to be alive", "Never flying these deathtraps again", "We almost died 9 times.", "That time I died in a plane crash", "Gryder Gryder Gryder, the New Mayday Mayday Mayday"

I tried looking around but only finding FBO, manager, and Clearance Delivery numbers? I have my home field’s tower phone number in my phone, but good to know if and where to look in FF if you can advise.
How about Check Alternator?

One of the biggest problems I find with older planes like yours is the human factors aspects, like what you dealt with. You'll be able to make minor changes to help with that, and as you know the plane, it will become less of an issue. But, newer planes defifnitely actually think about human factors now.

Say "Gryder" three times and he appears, kinda like the Candyman. Or Beetlejuice.“Gryder, Gryder, Gryder”. That made me laugh out loud.
The second time it happened was after I installed the instrument below. Saw the yellow "battery discharge" light in time to make it all the way back to Tucson before the battery died enough to affect the radios.

I like whatever the manufacturer and/or modifier called it. Makes it easier when you get to the checklist or other documentation that uses that that terminology to address the malfunction.I like "Low Voltage"
This thread could be a commercial for an engine monitor. my EDM 700 would have started flashing way before I started losing power.
It could also be a commercial for training and systems knowledge.This thread could be a commercial for an engine monitor. my EDM 700 would have started flashing way before I started losing power.
Made landing anyway, then did what needed to be done.
LOL. No, flew the WAAS upgrade over certain waypoints to make sure it was calibrated correctly.Burritos the night before?
