A very disturbing discovery in my RV
My RV is sitting at a paint shop waiting its turn to get new colors ,
after months of waiting work finally begun , and all the moving parts were removed , i was called to the shop yesterday , the owner wanted to show me something very disturbing , considering i ferried the bird from Virginia to New york , and did all kinds of maneuvers with a renown RV'er to get familiarized with the airplane , i THANK GOD day and night disaster didn't happen , the prebuy was done by someone who weights very heavy in the RV world , i paid over 2K just for the inspection itself , enough said , here are the pictures . |

Yikes!! That wouldn't be good to discover in the air. Ailerons work better when they work.

how did the bolt even stay in , with gravity ? |

Possibly the only thing that kept it connected. Correction I hadn't noticed there was more than one photo so initially I had only looked at the first one. Now I realize this is probably an RV-9 which has the bellcrank flipped around with the aileron interconnect push/pull rod at the bottom. First hand example of why specific bolt orientations are specified. |
Concerning indeed, especially given that a paid inspection happened.
That said, I'm curious if Scott or anyone else knows what the impact would be if the pushrod became disconnected. Absent it jamming, and acknowledging that you'd effectively lose the up control stop for the opposite (good) aileron, would control authority from the opposite aileron be sufficient to fly? |
Trust but verify Sibirsky. Dang I flew the bird and even gave her a good workout. In spite I gave you the recommendation on the inspector I still have the same opinion on all these pricy pre buys. I voiced offline to you and I stick to it.

Something similar happened to a -10. Builder removed the nut in the pitch control circuit to ?temporarily? insert a rigging template. He forgot to re-install the nut. Bolt came out on final, nose first landing did in the nose gear, prop. Fortunately no injuries.

If the bolt for the lateral push/pull tube fell out? Chances are pretty high it would result in jammed ailerons. |
