While completing my Condition Inspection I noticed a crack.
The crack is on the bottom horizontal tube, just inboard of the short bracing tube that ties the gear leg tube to that horizontal tube.
My engine mount is circa 2009 and supports an O-360. There are no gussets on this mount.
The current manufacture of the mounts, which is different than the person who made my mount, said he now machines the gear leg tubes rather than nesting and welding two tubes.
The mount will come off and be sent to www.super-12.com
where Steve will create a jig from my mount to make sure the six firewall bolts and the dynafocal mounts are all in the same place in space. This is important to make sure the mount will bolt back up and the prop/spinner will match the cowl.
Once my mount is in his jig, Steve will cut out the cracked tube and the old gear leg tubes and weld in the new machined gear leg tubes, cross tube, and gussets. Then it will have to be drilled to match my gear legs.
Next time you have your cowl off, please inspect it carefully for cracks.
