CTSW Stabilator Gap Seal Question

[Jim Meade]

My 2007 CTSW shows tape residue marks which indicates there was at one time a gap seal on the underside of the stabilator at the trim tab hinge join.  I looked in the parts manual and didn't see a reference to a gap seal.

My plane has Bowlus tape on the top side of that hinge.  That's a different issue.

Can anyone confirm for me that there are mylar gap seal on the underside of the stabilator on the 2007 CTSW?  If so, I'm assuming it was the same type of installation and material as used by gliders, which I am familiar with.

Jim,

My 2007 CTSW has the adheasive bead below suggesting something was there.  It currently only has Bowlus tape on the top side.  This is a 128 knot CTSW so I'm not sure I feel like something else is needed.

My 2006 CTSW did have a hard plastic gap seal fastened with rivits I believe.

Yes, it would have had the curved Mylar seal on the bottom. There was about 1/4" of double stick tape, and then a 1/2" wide Bowlus type tape covering the leading edge. Some airplanes had this on the top side, and yes the rivets went through the tape.

My 2007 has the mylar on the bottom, Bolus on the top.

John,

Do you know how wide the Mylar is?  

[Tom Baker]

Pre curved 25mm.

Thanks

After the original gap seal comes off I have used Bolus 1” tape on the top and bottom gaps since 2007 on all my clients planes with no issues.

That's what I have done at Roger's suggestion, works fine.

It's Bowlus, named after the inventor, not bolus, which is a kind of pill one gives to large animals "bolus: [ bo´lus ] 1. a rounded mass of food or pharmaceutical preparation ready to be swallowed, or such a mass passing through the gastrointestinal tract. 2. a concentrated mass of pharmaceutical preparation, e.g., an opaque contrast medium, given intravenously or swallowed. 3. a mass of scattering material, such as wax or paraffin, "

There's nothing wrong with using the right term.

Sounds like you are getting ready for a colonoscopy

Jim Meade,

Tom beat me to it. Yes 25mm. I actually measured and inch which is 25.4mm and it is curved.

[Jim Meade]

I was due for colonoscopy Friday, but based on the response here I cancelled it.  I feel better about it.

I ordered and received the right gap seal and the Bowlus tape.  Thanks to all.
