amekler Posted February 11 Report Share Posted February 11 I have noticed an air leak at the top rear of my door. I was thinking of replacing with an inflateable seal( had one in my M20J) but the bob fields website says m20A through m20K. Will it fit a M20M? Any thoughts on Knots2U seals?

Alan N9127M Yes it will I had one on my Bravo, I have a panel controlled one from FieldS I haven’t installed still in the box, I’d consider sending if you want.

Jetpilot86 Posted February 11 Report Share Posted February 11 How much difference does it make in decibels? I know I’m around 100-105db’s in my Bravo. Quote Link to comment Share on other sites More sharing options...

Fritz1 Posted February 11 Report Share Posted February 11 I bought a factory door seal three or four years ago but never installed it, glued a strip of 1/4" hollow windlace material from the aviation isle of home depot to the straight bottom section of the door seal where there was a small leak and nursed the rest of the seal with rubber conditioner, installing the new seal is a tricky job as I hear, just did not muster the gumption since mine stopped leaking with minimum effort. Since the door is a fragile contraption does the small inflation pressure of inflatable seal cause any warping of the door and excessive pressure on the door locks?? thoughts??

amekler Posted February 13 Author Report Share Posted February 13 I called about the inflateable Door seal it is not stc for m20m and would require a field approval Alan Quote Link to comment Share on other sites More sharing options...
PhateX1337 Posted February 14 Report Share Posted February 14 I got this done at annual last month, was able to get a field approval no issue. Frustrating to have to do that, but it wasn't a big deal. It makes a big difference in sound levels as others have mentioned. Don't have measured before/after dB readings though.

amekler Posted February 14 Author Report Share Posted February 14 I've been told here in NH the Portland FSDO is understaffed for field approvals but I'll make some calls. Alan Quote Link to comment Share on other sites More sharing options...

Do you have an after? I think I was 105 without, and will get to check again next week. Quote Link to comment Share on other sites More sharing options...

Nothing but you will notice resistance on the door handle. It's enough to give pause. Quote Link to comment Share on other sites More sharing options...
