It is literally just re-tightening 8 screws on the spinner to a specifc torque, so I asked my local A&P to do it.

I just spoke with a Mechanic friend that had a plane in his shop that lost a screw. My head scratcher is why a flat head screw how antiquated? and 44-46 in-lb on a flat head screw?!?! thats a monster torque for a flat head. I wonder if they are trying to keep them on with torque and not a secondary retention like a locking nutplate...they should change that fastener.

FYI my local mechanic just completed the SB and said “all the screws were loose”.
