It is not an AN bolt. It is a welded stud added to the nose gear lower assembly. The assembly is steel.

I wouldn't think they would shear like that since they are more elastic than a Home Airport Depot Grade 8...... _____ From: KRnet <krnet-boun...@list.krnet.org <mailto:krnet-boun...@list.krnet.org> > on behalf of robert7721--- via KRnet <krnet@list.krnet.org <mailto:krnet@list.krnet.org> > Sent: Monday, February 24, 2025 5:32 PM To: 'KRnet' <krnet@list.krnet.org <mailto:krnet@list.krnet.org> > Cc: robert7...@aol.com <mailto:robert7...@aol.com> <robert7...@aol.com <mailto:robert7...@aol.com> > Subject: Re: KRnet> Need a Propellor and nose fork assembly. Don't see this one as a regular maintenance item, looks like a fatigue failure. I do have over 1100 hours on it, lots of landings to go with that as well. This is buried in the nose wheel assembly pretty deep. You don't even disassemble this when installing it during building. Not sure how to check. Definitely would have thought the strut would fail before this bolt. Maybe during the annual inspection, you could get the nose gear off the ground and rotate it and check for issues.

Was the bolt worn? I tried to make it a habit on annual inspection to rotate any bolt that was capable of rotation such as in control cable connections. I would give each a 1/4 turn to cut the wear rate by a factor of 4. Larry Flesner
