Bob_Belville Posted January 21, 2014 Report Posted January 21, 2014 I have a JPI 930 which includes OAT and I never look at the original "mechanical" indicator. (In order to get at proper viewing angle I have to lean well forward and crane my neck.) It's not bothering me per se but I'm considering removing it. It's unnecessary drag, it's a little bit in the way... putting the canvas cover on the plane would be slightly easier w/o fitting the pocket over the probe... What are the options for plugging the hole in the side window? Any reason, other than possible backup, to keep it? Quote

Short of replacing the window, the only thing I can think of is a car firewall grommet. One that is solid and not with the hole pre-cut in it. Sent using Tapatalk 1 Quote
N601RX Posted January 21, 2014 Report Posted January 21, 2014 I filled one with clear epoxy, but it was very noticeable and had small bubbles. I knew I was replacing the window later on so I looked as it as a temp solution. You can also buy a piece of acrylic rod and some acrylic cement. Get the rod very slightly larger than the hole. The cement will melt them together and form one piece. It can then be sanded smooth and polished. If I remember correctly this is described in detail in AC 43.13. The process is described in detail with pictures on page 3-97 of AC43.13-1b. I think Lowe's still sells small scraps you could practice on. 1 Quote

flyboy Posted January 21, 2014 Report Posted January 21, 2014 Mine was removed before I bought the airplane. Someone installed a firewall grommet, then put a bolt through the hole of the grommet, couple of washers and a locknut. Quote

carusoam Posted January 21, 2014 Report Posted January 21, 2014 Changing out that window is about as much effort as using an acrylic based glue to fill the hole. The next challenge... If you have the original coke bottle green windows.... The modern gray tinted window will stand out. A new window can be purchased with a new "storm" window. The part that opens....

N601RX Posted January 21, 2014 Report Posted January 21, 2014 It might be a good place to put your Sun-In-Fun 2013 sticker if you still have it. 3 Quote
Bob_Belville Posted January 21, 2014 Author Report Posted January 21, 2014 Here you go: http://www.eaavideo.org/video.aspx?v=1967301183001 I like that. BTW, I could not get the video to run all the way through on my computer. I tried both Chrome and Firefox. (My internet is HS cable but only 3mb download.) I was able to watch on my 4G smart phone in both 4G and WIFI modes! In the WIFI mode "play" caught up with the buffer a couple of times but I could restart after a few seconds whereas the computer would not restart. Any wisdom? Some Windows or browser setting? New laptop w W8.) Quote

Monticello Flying Club Posted February 3, 2014 Report Posted February 3, 2014 The only other reason to leave it in is its great role as an ice detection device. I always pick up ice there first. Anyone considering removing it, just make sure that your other monitoring device is certified as a primary instrument. Many aircraft monitors are not certified as a primary instrument. Quote
jetdriven Posted February 3, 2014 Report Posted February 3, 2014 Try a barrel nut with a couple washers. Barrel nuts are similar to those bolts that hold the storm window in. They are flush on both sides. Quote
