The Murphy Builders Site

Looking for recommendations,
I thought it may be a good idea to get a baseline non-destructive test (MagnaFlux?) done on the Moose spring steel gear legs. The thought was to be sure that the parts aren't starting off with some latent internal defect. Is a MagnaFlux the right test to do? Does anyone have any experience on what could reasonably be done?

Thanks for the input,

That steel leg is not going to break before everything else lets go first!
IMHO the gear leg is thicker than it actually needs to be, and of course
like most things in the kitplane industry (at least from Mfg's that like to
avoid lawsuits) overdesigned on purpose.

All Magnaflux is going to show you is if there are any cracks as received in
it's new state.

Jack,
My experience with the gear leg is that it is not the problem. The attach
fittings and hardware are the weakest link. The landing gear could use a
better design but MAM considers it good as is. The new design should change
the shape of the gear leg to have it bent again in the gear box. I've said
it before and I'll say it again "the landing gear is the weakest part of an
otherwise great airplane".
