Wots this bumper for?

If you ever hit the bumper IN FLIGHT you will probaby be hearing lots of much louder noises than the bumper makes! Don't worry, after the last loud noise it will get REAL QUIET. ;-)

FWIW, My bumper is quite hard. I think that it's made mostly of wood. It's not compressible at all like pipe insulation might be.

Also FWIW, my ship has only one of these bumpers. On the co-pilot side.

Most that I have seen were lower on the tube, and contacted the tube on the "H" column.

The primary elevator stop is in the tail; this limits the up-and-down movement to the limits specified in the TCDS.

I guess the bump stop is intended to prevent over-zealous application of forward stick to reduce cable stretch.

This seems the most logical. Loose cable tension = hit the stop(s) = adjust tension to avoid the stop and allow for full travel of the elevator.

I crawled, slid, and squirmed under the panel today and discovered a bumper attached to the tubing where the right steering sprocket might hit. It doesn't but could with enough forward pressure. It was painted white like the supporting tube so I missed it earlier. No left bumper. There is a piece of rubber fuel line wrapped over the left steering wheel tube to prevent the wheel when full forward from hitting the radio knobs when turned ...smart idea by the previous owner who did a great job on the rebuild.

Big grin reading that. When I bought N34237 I wondered why the knob on the radio was all bent and battered. I found that wiggling the ailerons up and down on the pre-flight with the elevator full down and the wheel full forward was beating the living $#!7 out of the Icom fequency selector knob as the wheel swung left and right. I added a two-inch piece of clear tubing split length wise on the tube just ahead of the wheel. I've never needed full forward elevator for anything, and If I really needed it and pushed, the split tube pops off. I tried it. Until that unlikely event, my new radio knob remains unbent.

Yes exactly a dupe of a potential issue...ICOM A-200 panel mounted and the RF selector knob sticks out in harm's way. I was going to put my GPS clamp-on mount on that tube but now I'm glad I didn't.

Basically I'm going over a plane that's new to me (had one 40 yrs ago but forgot most) and looking for interference fits, un-secured wires and cables, loose this and thats (like the steering universal joints and pulleys), any chafing or leaks. Once I start flying regularly I'll join the no worries club once I know what's in front, behind, over, and under me.

Re: Wots this bumper for?

Well, a quick peak under my instrument panel and no bumper to be found on either side. Hmmmm....... I thought the yokes resting against the panel was normal. So much for that.

Maybe something like one of these would work...same for replacement bungee bumpers: http://www.awesometools2.com/handle-savers/
