Any tips or tricks for replacing the side glass in my J?

[helitim]

Getting ready to replace all 4 side windows and wondered if anyone has any special tips or tricks to make my first time any easier? Will be using the 0.250" thicker glass with a solar gray tint. I did spring for an experienced A&P for the windshield but, I believe with a little help, I can do the rest myself.

Just be patient, and carefully drill the holes. Nothing really complicated about the job.

I did this to my plane.  The holes need to be srilled oversize (I forget the actual size just now).  i have an acticle qritten by Dugosh on the subject if you want it.  Just e-mail me.  Also, the holes need to be carefully countersunk with no chattering of the bit,  Use the correct sealant per to manual (however I believe LASAR has used the fuel tank sealant given that it is "stickier" but also harder to come apart.  You can check with them on this one.  You will also need a copy of the STC (from Mod-works) for installation of the 1/4 inch windows.  Mod-Works is presently out of business.  You can e-mail me for more info at johnabreda@yahoo.com or sens me your phone and I'll call you.

I had a pretty extensive post when I did my side windows. A lot of photos of process in my gallery. Good luck. Scott

Big tip!!!! DONT USE THE OLD WINDOWS AS A PATTERN FOR HOLES. The only way to make sure things line right is a lot of in and out. Marking as you go.

Do you need an stc for replacing the windows for 1/4"? It's not a major mod, heck it's even owner maintenance.

Also, Clarence flush mounted his side glass. Look into that.

When I purchased the glass, I simply gave them the serial number and they asked which thickness I wanted. No mention was made as to an STC for the thickness increase. Maybe I need to chat with them tomorrow about that.

I will do a search for Clarence's flush mount technique

Scottfromiowa: do you remember how your thread was titled or, do you have a link to the data?

Thank you to all the suggestions

I upgraded to .250 windows when I replaced mine.  We did not use a STC, we referenced the statement on GLAP's website in the logbooks. PRC will set quickly in hot weather, don't use b1/2.  Use b2 or even b4, however it takes b4 several days to completely set. A good tape job will make cleanup go easy.  I have a post with some pictures from where I did mine.

 

Q3: Why are your thicker side windows not STC'd?

A:    Our regional FAA has determined where STC's are to be applied.  Keep in mind that not requiring an STC keeps the paperwork down and a 337 form is not necessary.  We have been told by our regional FAA office that STC's have been overused for minor changes, thicker side windows are considered to be a minor change by our regional FAA office (Chicago).
