On the flap hinges where there is no bearing they use castle nuts, but anywhere there is an actual bearing (rudder, elevator, ailerons, bell cranks, etc.) they just use the bolt to hold things together, but all pivoting takes place on the bearing itself. Only where the bolt itself may rotate do you need to use a castle nut, or where there is a heat source (engine compartment) that could melt the nylon.

AC 43.13 most definitely requires castle nuts and cotter pins in such locations. Locknuts can and will loosen if rotated enough. > > Jack Philliips > #40610 > Raleigh, NC > > From: owner-rv10-list-server@matronics.com [mailto:owner-rv10-list-server@matronics.com] On Behalf Of Danny Riggs > Sent: Thursday, September 08, 2011 11:53 AM > To: rv10-list@matronics.com > Subject: RE: RV10-List: Re: Horizontal Stabilizer bolts loose at annual > > Soooo, > What is the theory about substituting castle nuts and locking pins?

I obviously torqued the assembly from the top. Not the best way to do it. You do not get an accurate torque value. If I were building again -bolts bottom-up. That way you can torque the nuts precisely. > > > 3.

It came with the Airflow Performance injection system. My cylinder #5 has always been the first to reach peak EGT when leaning. I pulled the injector, thinking it might be dirty. It wasn't, but I noticed it had a band around it, indicating that it was the smallest of the three standard injectors AFM sells. Does anyone know if this is the usual setup? I didn't look at any other cylinder. Are they all "one banded"?
