Troy --
I agree one might be tempted to use AN4 bolts back there on the torque tube,
but I wouldn't want to be the one to remove/replace the bolts after the
fuselage top is on. The arrangement they have looks geared to future
maintenance through the access hole. though it would still be tough.
The pins have shear loads only, and thus none which could break the cotter
pin. There are lots of planes over many years whose wheels are attached with
a nut subject to rotation, secured with a cotter pin, and subject to
considerable loads, vibration, and abuse. They don't seem to fall off,
though.

<< Hi All,
Has anyone used AN bolts to secure the drive plates and pitch controls to the
torque tube instead of the pins with cotter pins hidden back? And why are they
horizontal instead of vertical just in case a cotter pin were to break? It
seems they would be easier to inspect if they were vertical.
Thanks.
