Aux Power Cable Short

I've been months in the shop and finally coming out but this was an area where we discovered some issues and "wire rot". Because of it's location, out of site out of mind, obviously neglected and overlooked by priors and a similar problem in the making. I'm an E model and it is under battery box. Be sure to take battery and battery box out and look down in this area all the way. Plus plenty of corrosion inducing gasses and dribbles in the region. Glad you're ok!

I'm still in my first year of ownership but have gotten to the point now that almost everything has been changed out. Somehow this cable, really though to find and almost looked like a protected control actuation cable of some type given is color and positioning.

Thanks for sharing your story. Nice job in your handling of the emergency. I have an email into my IA at Lumanair to have this inspected on my C337G.

Thanks again...,

Removed the battery and battery box this afternoon on my 1973 C337G and got a good look down there. There does not appear to be any issue on my plane as you described on yours. The wire in question on my plane must have been routed differently than yours as it is no closer than 5 inches from the cowl flap actuator rod. It runs from the back of the aux plug into a protective sleeve that runs under the battery box and then up the firewall still encased in the sleeve until the voltage regulator. I feel like (fingers crossed) all ok on my plane. Fire is scary.

Thanks again for your post.

Great to hear Ed. Not sure if the cable was ever changed out in the past. It is a Cessna cable, but not documented as replaced in the logs. All said, it did near $6K worth of damage.

I hear you and I believe.

I'm not mad at it either, I'm old too and break. I bought it a cargo pack while it was recovering. I thought my mechanic was going to pass out when it was delivered to his FBO!
