Brief Description: Started on spar service bulletin
|
|
I've been unable to focus on the project in recent weeks because I don't know what to do next. I don't have the money for an engine, and apparently it's too soon to start on the canopy. Eric at Van's says the rear window should be in place soon, which means it's time to start assembling the airframe.
That's a little odd because I've heard I shouldn't start adding the tail stuff until the fuel system is in place, including the fuel pump, ELT etc, which sit on the back of the baggage bulkhead and are easy to reach only with the tail section off.
But I'll start assembling what I can, which means it's time to get to the long-postponed stabilator spar service bulletin to strengthen the area around the hinge brackets.
So I removed the existing brackets, as directed, and matched drilled a doubler underneath each, then removed the gizmos with the stops (they're to be thrown away) and removed three pop rivets on each forward side of an internal rib. I prepped the doublers. They are to be match drilled into the forward spar (man, there's a lot of new holes going into the spar!).

I found a nutplate that a rivet hadn't been installed. Stuck a CherryMax in there. Expensive oversight
