I am a fairly new owner of an older bird, a C-182A (57 model) She is in pretty good condition, but like all things older there are some details that need attention. Specifically the right hand lower door hinge is deformed and the IA says will have to be replaced at annual so I have begun the search for a serviceable part. I can find plenty of later model hinges, but this one is made a little differently (see image below) The hinge on the left door has already been replaced with a later model hinge, requiring some added doubler skins and rivets. I don't know if the guy I use for repair work will like that idea or not, so I'm still looking for the "correct" part.

Anyone have any hidden gems or ideas where I might look that my google searches have not found? It never hurts to ask and I know there is a lot of experience on this site caring for these older machines.



This is the hinge that I need to replace.

Thanks guys!
Mike

What exactly is deformed? Looks like the door half is bent just aft of the hinge. Also, from the cherry max rivets it looks like it's been off the airplane already. Maybe remove again and press flat in a vice. Talk to your IA about this option.

If it must be replaced, the first step is to determine the part number. From my 180/182 IPC, looks like that lower hinge assembly is p/n 0411579-5. Now call or check online with Univair to see if they have any in stock. Ditto Prefered Airparts. Ditto whoever seels genuine Cessna parts. When they don't have any, or when they want $1200 for one, start calling the salvage places--Discount Aircraft Salvage in Deer Park WA, Skywagon City, etc. Also check around your local airport(s)- you never know who has extra parts or chunks of airplanes laying around their hangar.

Good luck with it.

Any of that stuff is pretty easy to come by salvage.
Robair repair in Washington makes allot of the later model hinges for way way less expensive then Cessna.
Your hinge was but on with the worst rivets possible. Those are not even cherry max. They are Olympic pull rivets. Good for very few things mainly non structural.
I have seen a doublers welded over the top, new hinges welded on to repair those guys.

I know the rivets aren't correct and it obviously has to come off. I feel pretty safe in betting that it can be pulled and straightened out, but eh IA is afraid it will break when we try it. Of course there is always that chance, so he wants me to have the parts in hand before we tackle it. I have several months before the "deadline" so it should work out ok. The previous owner has a later model hinge he is sending me as that would make it match the left door.
The shame of this story is, the airplane came with a set of door stewards, but they weren't installed. They are now and I really like them. If they had been on there, I would bet that this damage would not be there. Most of this stuff happens when the wind catches the door and the person operating it isn't prepared to hang on to it.

I know I need the part number, but I don't have a parts manual in my hands or possession. I will find someone with parts manual access soon, just have to keep trudging along.

Number seven is what you're wanting. This is from my 180/182 parts manual. It was the right way on the camera but rotated but you can get the numbers.

Thank to all responding, now I have the parts manual and the part number!

Just need to locate one for less than an arm and a leg, plenty of time this fall ( I hope)

I might have that hinge on a spare door that I have. . I'll look at the door in the rafters tomorrow after work. . If I have the hinge you can have it for free. . Our passenger door is a jump plane door and will never use that hinge

Looks to me like an ideal candidate for an "owner manufactured part", fabricated under 14CFR Part 43.

Any repair or "upgrade" to this part would easily be a "minor alteration". A lot of mechanics are so fear-locked about this stuff that they soil themselves over really minor stuff like this.

If your IA is so terrified that he or she will not allow you to straighten out a door hinge, I can recommend an experienced IA on this forum. His prices are usually very reasonable, but they do go up sharply if you show up with a Hillary in '16 bumper sticker on your car.....

Easy Riser -If your mech is having major heartburn over a door hinge -maybe you need a better more experienced A&P /I.A. -yes I have parts -lots and lots of parts. I deal in old straight tail 180-182 very much. And yes if you show up with a Hillary in 16 price goes up &up&up . When these old straight tails were being built by some of my Witicia cousins -on winter break from the farm . If he's so concerned about the door hinge -put on a Jump door and be done with it. I also install Jump or skydiver doors. Cessna doors are custom fitted /and hinges are for 1 airplane and one airframe only -they didn't have a computer controlled cnc machine to keep them 100% match able .

Here is a picture of the door in our rafters. . The hinge doesn't look much better than yours. .


If you want it I'll drill it off. . If you can find better, I won't worry about it.

Those hinges are made of steel, not aluminum like the later ones, and will take a lot of abuse before breaking.
I would take it off, straighten it and figure out what needed to be "beefed up" do that and then reinstall. There could be some small amount of welding involved.
Some slightly oversized pins made from ss welding rod or piano wire will improve the fit between the two pieces.
Then again maybe you can find a "new" one, get over the loss of a limb and go forward from there.
If this is outside your IA's box, I would would be looking elsewhere for that service.

Of course your mileage may vary.

We might be seeing this as too big of a deal. The IA just wanted me to find a replacement as he was concerned that straightening it might break it. I thought it was steel as well and that said I am certain I can straighten it and stiffen it to be better than new. All the information I was finding indicated they were aluminum, but like I said, I sure thought it was steel.

On a positive note, the more I fly this bird the more I like it. I really haven't found anything to fault or complain about. It performs great and is extremely solid feeling to fly. I think she is a "keeper".

Bill,
I am aware of your expertise from reading through this forum from front to back. So far my 182 is doing great and I hope that I never have an issue that I can't solve locally but I WILL keep in mind that there are experts out there like yourself that can and will help with keeping these old birds flying and in excellent shape.
As I said earlier, I am pretty sure that I can straighten that hinge out. Not today though as I have a trip in mind for the upcoming weekend.

Blue Skies!

I sent you a pm but never heard back.

Mike

I didn't know about pm's.. I'll drill it off this weekend, and msg you once I've done that.
