<p>I did get around to running a bead of sealant under the windshield trim and it did cut down on the draft on the pilot's side. There was still some cold draft coming from the lower front of the door, seemed primarily between the lower corner and the secondary latch I had installed to snug the door against the weather strip and prevent the door from catching air and blowing off - a problem that has sometimes occurred with the fiberglass-framed doors (My STOL 750 is an edition 1 with the…</p>
<p>I did get around to running a bead of sealant under the windshield trim and it did cut down on the draft on the pilot's side. There was still some cold draft coming from the lower front of the door, seemed primarily between the lower corner and the secondary latch I had installed to snug the door against the weather strip and prevent the door from catching air and blowing off - a problem that has sometimes occurred with the fiberglass-framed doors (My STOL 750 is an edition 1 with the fiberglass doors). What I think is happening is that the lower-forward fiberglass flange that overlaps the door opening is bowed slightly outward below the secondary latch and catching high-pressure air:</p>

<p>I think there's enough pressure from this leak that it overcomes the soft, bulb-type weather strip. So, I made a diverter or fairing to direct the air up and over the door flange where it protrudes. I had some 0.025 L angle that I opened-up the angle from 90 to more like 140 degrees and, after trimming and paint, affixed it with 3M VHB tape:</p>

<p>Hopefully this will fix the remainder of the air leak and even if it doesn't, it completes the trim where there used to be a gap at the bottom of the side of the windshield! Although the VHB already seems to have a good bond, I'm going to let it cure some more and then try a test flight the next decent weather we get!</p>

<p>This time of year when the weekend weather won’t permit flying I often pull the cowlings and look around for either something to tweak that I’d spotted on a preflight and intended to address at the next annual, or for something I may have overlooked. There’s always something that deserves attention or could be improved.</p>

<p>After the first oil change on my Gen 4 Jabiru I thing a quick drain oil valve is next on the list. I should probably also make some plugs for those NACA Ducts before spring.</p>

<p>Nicely done! I’m glad to have inspired something! I’ve got a few more mods I’m working on……. I’ll post when I’ve got completed work to show.</p>
