I am doing the annual on my 6A. I re-torqued the prop bolts 22hrs ago (though that was about 10 months).Â  Check list calls for re-torquing them, but I don't see that it's worth disturbing the thing.Â  Catto recommends a much longer re-torquing interval than the average wood prop anyway, due, I guess, to the fiberclass outer layer of the prop. 

 



Any opinions on this ?

I removed my Catto prop several times each year. Actually every time I removed my cowl. This was just the easiest thing to do for me on my aircraft. My point is that each bolt should be loosened before it is re-torqued to avoid any errors. How often to re-torque the prop depends on what climate you live in. Annually might be fine in the desert but monthly might be necessary in humid areas prone to wide barometer changes. Your airplane, you must decide!!!
