Hello,
So I have been trying to isolate some rather annoying vibration on the new 10 that can be heard during taxi and in flight at certain power settings. I believe I have isolated it to the top part of the cowling where, with the engine running you can see it vibrating significantly. Upon further inspection it looks like the piano hinge is significantly larger than the wire itself which results in a lot of play and the allowance for the cowling seam/hinge to vibrate causing the noise. I took a video of it. Also in flight you can see the play allows for the cowling to lift from air loads. Measuring the top cowling wire it is around .0815 and the hinge is about .14'
Writing to see if this is normal to allow for east of the wire to curve around? Has anyone else experienced this? Any smart solutions out there? Using a .14' wire seems to be quite a thick wire but maybe this is the easiest solution. Replacing the hinge would be a task and require repainting.
Thoughts, insights, comments, suggestions always welcome!
Thank you!
