Anyone know of good way to replace the rubber hose portion of the pitot tube in the wing of a B35

The rubber hose between the pitot tube (hanging under wing) and metal tubing inside the wing needs to be replaced, but I can’t figure out a way to get to it any idea’s?

Model: Bonanza B35
Aircraft Serial Number: D-2222

Richard, where is the rubber tubing you are looking at? If it is at the pitot mast, you may be able to work blind with one hand at the opening. If it is near the wing root, you are in for an even tougher time. My “G” has a kick panel air vent assembly on each side. It I remove these, I can gain some access to the wire and tubing coming into the fuselage from the leading edge of the wing. I am traveling this week and don’t have my tech data with me. Norm Colvin wrote in “Colvin’s Clinic” that getting at some of this stuff actually requires pulling a wing. It is not unusual to see aircraft with custom access panels fabricated and installed for jobs like this.

I can not get to my airplane (G-35) for a few days to take a look and have never replaced any of the pitot hose but I seem to recall that the access to some of that plumbing is via the landing light mount. Take a look and see.

Problem half solved: Thanks for the respones guys I spoke with a friend of mine (Dave) who's an AP at Hollister Jet Center, Hollister (KCVH) he explained one way he's been able to change that hose out. You have to open the aft inspection plate hole in the left wing the one that exsposes the alerion cable. And reach up through that inspection plate hole to reach the hose. You have to have"skinny" arms, to get your arm up through the inspection plate hole in order to pull the hose off the metal tubing in the wing. I emphasize skinny, I couldn't my arm passed my forearm.
Wife to the rescue. After much whinning, I was able to get my wife to give it a try and she was able to get the hose off after much struggling and putting her body in some not so femenine postions. If it wasn't for her I don't know how I would have gotten that hose off. I've got the new hose ordered and when it arrives it will be whinning time again. Moral of the story have a wife with skinny arms.....to be continued.

Lew I pulled the landing light out but there’s no way I could see that allows access into the enter wing area the end of the metal tube for the pitot is surrounded by wing spars. Seems like engineers never build anything with mechanics or AP’s in mind.

Richard,
In the long run it probably would be cheaper to just go to the local flight school & find some 6'+ tall gangly student who hasn't yet filled out. Women, as you probably well know, have extreeeeemly, long memories. Good luck. LOL
