Just thought I'd post a comment about my seat pans, after my recent
re-upholstery project. When I stripped the seat pan I found significant cracking
along the front lip, and the lip at the top of the seat back. I have since
significantly reinforced the seat, but it's something people should look at
carefully at annual.
I added about 6 layers of glass in the cracked areas, and .025 aluminum
doublers which are riveted and bonded in place. I also upgraded to 3/8 wide
cable ties.
Just for what it's worth I weigh 170 and typically fly solo, so the seat is not
overloaded. I do have under the pilot seat a safety tunnel to keep the seat
off the controls as well if the seat should somehow bust loose.
Here's a pic with the upholstery installed, and even with the very big cable
ties in place they are hidden beneath the carpet which is velcro backed
under the seat cushions.
