Default Bigger weld bead doesn't necessarily mean deeper penetration...... .........

As posted in a previous thread about the nose fork, supplemental testing was done on the nose fork at the request of the FAA after a botched landing accident.

A number of different forks were tested (big weld bead, small weld bead, etc.) and all failed under static load at very near the same load value, and well beyond the required load. The FAA was fully satisfied with the results of the testing.


This thread is about cracks that begin at the edge of the fork web, that if allowed to propagate, will likely result in the nose fork disassembling itself.

Default Nose fork inspection

I inspected my nose fork last night, 47 hours, all on pavement. No cracks found. I do treat my nose wheel with the utmost respect, as instructed by Mike Seager and John Albury.

Last annual in March: 438 hours and no cracks. If I find any in the future I'll crank up my under utilized TIG welder and do a weld repair.

Just checked at 106.2 Hobbs. In perfect condition. Any suggestions for appropriate log entry, this will be my first SB since taking possession of the plane. Thanks.

So far it looks like there are not very many cracks out there. Not sure how many it takes to justify a recurring SB. Hope we can get a count and cause at the end, but I guess that we are stuck with the SB. Oh well.............

You need to get a starduster or pitts project going with that welder!

Default Nose fork collapse

Bob,

Was your fork replaced at "no charge?" Mine collapsed 200' after landing roll-out this past weekend. My -12 also has the old style fork.
