Autopilot Pitch Servo Bracket

Finish deburring aft fuselage.
Match drill pitch servo bracket. Didn't say anything about it yesterdays terse log entry, but the drawings for the TruTrak pitch servo are wrong for the 9.



The problem is that the bellcrank bulkhead isn't built as shown in the TruTrack drawings. The flanges on both point outboard, not alternated as shown in the drawing. Not a big deal, but it does require drilling a few extra holes in the bottom of the 778 bottom skin.


If you plan on installing a TruTrak pitch servo, you can wait until later to install it. But do yourself a favor and don't set these four rivets (that I just drilled out) when building the bellcrank ribs.
