Hello everyone. I have a Mooney M20J 201 and a few days ago prior to engine start I moved the yoke forward and backward for full range. While doing so I heard a rubbing/scraping noise that I eventually determined was coming from beneath the right side floorboard. After removing the panel beneath that area I discovered the source of the problem. As the yoke is moved forward and backward full range a pushrod beneath the right floor is making contact with a metal rod of the frame.
The contact is not constant and only happens at a particular phase during the yoke movement. At that time the pushrod drops briefly, makes contact with the frame and rises again. I also noticed grease was packed on the frame rod at that particular spot as if this has been happening for some time. There doesn't seem to be any wear from the contact and I can't imagine this is normal. Has anyone seen or heard of this? It should also be noted that is the first time I have noticed that scraping noise and I have had this aircraft for 3 years. I will try to get photos and post them if needed.
