So doing an Owner assisted annual, and my mechanic said he’s never seen these before, I’ve also never seen them on another Tripacer. Bought the plane with them installed. Have you all seen these before? Probably going to take em off, would like to leave em on tho.
I've thought about it before, after I read about cub guy that ended up with a bees nest in the fuse (talk about "aviate, navigate, communicate" concentration)
My thought was "brushes" attached on the inside of the covers. Kinda like what you would see on a car floor mount shifter. As the trim moves through positions, it sweeps between the centerline of brushes attached along both sides of the slot in the cover.
I saw a PA22/20 that had a clear plastic panel that rode on the LE of the stab (one each side of fuselage) and covered the openings.
I can't recall how they were attached to the tubular section but probably similar to what was pictured in Fatts' photo in #1.
I thought I took a photo of it but that was maybe four years ago, on a phone that I no longer own.
Who hasn’t looked at that gaping hole and wondered if something more elegant could be done about it. Stock solution is probably the simplest and safest, but you would think there could be a reasonable engineering compromise design to deal with all the things mentioned earlier, mud dobbers, critters and their nests, dirt and debris that turns into mud on the inside of your plane when it gets wet, etc. I wonder if some silicone baffle seal material might be used with maybe only attachment on the leading edge. Or maybe it’s a vertical slit in the silicone right up the middle. Just a thought.
