door bumpers
NOTICE: None of the parts on this web site are PMA’d!
You and your IA will need to decide whether these meet the requirements of owner-produced parts for installation on your airplane.
| The airplane in question is a 1976 177B. Figure 1 shows my pilot’s side door frame prior to removal. The Door Latch Bumper (Cessna® p/n 2012127-1, figure 17-66 of my illustrated parts catalog), hereafter referred to as “bumper,” is made of thin aluminum that has snagged and torn on the door latch over the years. |
Figure 2 shows the co-pilot’s side bumper removed from the airframe. Note that there are two stubby machine screws and two sheet-metal screws.
Figure 3 shows a set of replacement bumpers ready to be mounted to the airframe. The edges have been deburred. The smaller, sheet-metal screw holes are chamfered but you may want to shallow out the chamfer by using a 3/16” drill bit. The replacement bumpers are made of 0.060″ 304 stainless steel and weigh about one ounce each. The bumpers have been bead-blasted which gives a matte finish and mostly eliminates the tool mark from the manufacturing process. If you choose to paint these, the bead-blasting should provide a better surface to which the paint will adhere.
On my plane, I needed to drill a new hole for the lower sheet-metal screw on the pilot’s side. The upper machine screw on the co-pilot’s door was also not quite lined up. You may find clever ways around this or just leave that screw out altogether. It’s plenty strong without it.
Figures 4 and 5 show the pilot’s and co-pilot’s door frames with the new bumpers installed.
Now available, at no extra charge, are these bumpers powder coated in white. I also have a few sets in red and blue. If you’d like a different color, please contact me to see what we can arrange.
Polished stainless also looks great. Choosing that option will incur an additional cost of $25.
