For general info group, I have used the -3 aluminum fittings and found
them more than strong enough. A getoff that broke the caliper on a guard rail
didn't fail the fitting. While that isn't total surity it does show that the
fittings are tough. I used the Earl's fittings then. I wouldn't hesitate to
use them on the aircraft.
