I took my plane (and just picked it back up) to its 1st inspection. I enjoyed the experience in spite of the fact that it was a lot of work! I was also very impressed with my mechanics (2). Very professional and organized. What you would hope for in someone that is working on your plane! If anyone is in the NJ area and looking for a mechanic, shoot me a PM.
Anyway, I have 2 questions. One, is there a reason the floor panels are held in place by 2 diferent size screws? I believe they are all size 8 round head screws but there were 2 different length screws in my plane. There was no apparent rhyme or reason at least in some cases as to why a particular length would be chosen. I mapped every screw when I took them out because I didn't want to mix them when I put them back. This was a very tedious process.
Two, I had what I thought was a missing or backfiring under low power as I would approach the pattern. It was a random cadence and not terribly loud. After the inspection, the situation is worse. I now have a pronounced drumming coming from my belly skin under my feet I think. I tried to research this but couldn't find more than a single similar thread. The suggestions were that the skin (or firewall in this pilot's case) was flexing and causing the noise. Can anyone shed more light on this phenomenon? The was no resolution in the other thread so I would be interested to know if that is a consensus answer or if there are other things that might cause this problem. Also, is there a fix or if not, some way to fly around the problem. It is unsettling to say the least.
Thanks! Andy
