Brief Description: Bellcrank Orientation Fix
|
|
The first part of resolving a problem is to identify it-which I did in the previous session, and now it is just a matter of climbing into the tunnel and doing the work. I haven't been looking forward to this fix because the back of the 8 is cramped, dark, and hot, and getting into and out of the working position back there is cumbersome. But this issue isn't going to solve itself, so let's "jump" in!
I tried to pre-plan all of my needs and set up tools that I might need by the fuselage opening to reach the tools without getting out, saving time and energy. Climbing into the tunnel, I first surveyed what needed to be un-done and then started un-doing the fasteners to flip the bellcrank. With just a few times to come out and get something else I needed, I was in the tunnel for over 3 hours. I spent most of that time removing unrelated items that were in the way and also trying to see if I could flip the bellcrank around without removing the forward pushrod as that connection is at the bottom and back with minimal access - but in the end, no dice, it must come off. I disconnected the forward pushrod connection and then the aft connection and removed the bellcrank. The un-doing is done so that is progress.
