Dream to fly Posted August 19, 2017 Report Posted August 19, 2017 Been flying and actually everything has been fine. I refueled and decided to take off to fly the lake and after gear retract the plane had a vibration. I did an inflight mag check and no change. Lower the gear and it goes away. Flew it to a towered air space and had the tower verify gear down and gear up. I am assuming it has to do with the gear but it feels like it is in the floor boards. I landed and it all feels normal but not sure where to look. All the doors seem tight and the gear is not bent.

I thought about that but not sure how to mount it. But now that it is on the ground I am calling my AP to bring the jacks. I am going to check in the morning with the bird on jacks. I am wondering if its a door or a panel.
gsxrpilot Posted August 19, 2017 Report Posted August 19, 2017 Sticky Mount!! Is no one paying attention? I keep saying it, but evidently everyone thinks I'm nuts. Actually if you're just going up for a flight around the pattern, a suction mount will work fine as well. I used my GoPro on a suction mount to diagnose an AOA indicator issue under the wing in flight. 0 to 1000 ft won't make any difference to the suction mount. 0 to 10,000 and the change in pressure will let it come loose. 1
Gary0747 Posted August 19, 2017 Report Posted August 19, 2017 I suspect a gear door vibrating against the airframe. Do a retraction test and check for a door not seating firmly against the airframe and vibrating due to air flow or engine vibration. 2
Chocks Posted August 19, 2017 Report Posted August 19, 2017 I'll say it again for you Rocket;STICKY MOUNT! Attach it to the underside of the empennage just behind the wing so you can see all three Sent from my iPhone using Tapatalk 2
Dream to fly Posted August 20, 2017 Author Report Posted August 20, 2017 Sorry guys for the delay, I found the problem late Saturday. The Cowl flap actuator rod on the left side some how came apart. The bolt fell out. I am thinking the bolt broke but not sure because both pieces are missing. I would think a lock nut couldn't back off. I replaced it with another fine thread locking bolt and blue Loctite it for added protection. Took off and the noise was gone. Easiest fix so far. 1
