Dave,
Share with us the aluminum alloy and thickness you used for your owner produced part.

Paul
2024 T3511 aluminum. As I recall 5/16" thick but it needs to be surfaced down to .295"

James, We are not familiar with the trigger style, do you have pic or manufacturer? Thanks!

:shrug:

I think he's talking about this one, p/n 0513558-9. I think there was also a grommet to cover the edge of the carpet when this was installed.

CAP installed them in a lot of planes. We griped about it because it was change and it was new, but it wasn't really a big deal. Before sliding the seat back, you pull the "trigger" back to get the device out of the way. Pretty easy, as long as you remember that it's there.

Was that milled or waterjetted?

Before my Dad would let me solo his 180 on Floats (I was 16) he made do
a full pattern with me clinging to the the panel with a death grip around the structure under the throttle and the seat slid all the way back...
I was strong enough /light enough then to hold my self in a squat position pushing on the rudder pedals and supporting myself with the right arm.

Could not do that today...

Wow, this is a cool story. I am working on my private pilots license in a Cessna 150M and I had the seat slide back on take off, good thing 1. my instructor was there. 2. I am still tall enough to reach the pedals (doesn't take much in that plane). 3. I am working at AvFab and these guys can fix it lol.

Good on your Dad for making sure you were prepared for all scenarios before solo.

Thanks for sharing.

About to embark on a Cessna seat refurbish adventure. Bought all the pins and roll pins, and ready to order the more expensive parts from McFarlane if needed.

What I expect to be the problem is enlarged holes in the front/aft torque tubes.

In Dennis Wolter's CPA seat restorations articles, he writes:

Quote:

Next check the clevis pins that hold the reclining
and height linkage together. Any excessive
play at these points is eliminated by
reaming the holes to the next largest pin
size.
Another source of play is in all the
roll pins that are used to hold the seat and
its mechanisms together. Again, the fix is
to drill the holes larger to accommodate
a larger roll pin. We think it’s a good idea
to also secure the roll pins with safety
wire – an ounce of prevention is worth a
pound of cure.

I believe the mechanism and tubes are all aluminium.
Anyone had any experience with welding holes shut, and re-drilling to correct size.

Or is the upsized Roll pin/Clevis pin hole the better option?
Just drill to new size, or use reamers?

Has anyone had AvFab recondition their Cessna seat mechanisms?

Curious the outcome and range of cost. I've just sent them a request for a quote.

Make seat frames from.065 4130, they’ll outlast the airframe.

Is there a piece which goes on the seat frame itself with that, or is it just at attachment on the floor? I.E. what does the “hook” catch on?

I talked to them at Oshkosh and I want to say it was around $3000 per seat? with a price increase coming in 2024. I'm interested in what you hear back from them.

I had my seat slide all the way to the rear in a C205 right as I was passing about 50 mph on TO. Couldn't reach pedals or throttle, but could just barely reach the yoke. I managed to rotate and fly while folded in half until I had enough altitude to release the yoke and reposition my seat. It was "interesting". Happened back in mid '70s.

That's a good reason before takeoff for setting the takeoff trim to fly hands off at Vy. With a seat going back, the CG shift might reduce the speed to Vx, but you wouldn't stall.

I just paid a handsome sum to have a seat rail replaced in my 182, as it failed inspection for the locking pin holes being out of spec. It had to be done, nothing to mess with.
