I've seen the plastic locknuts melt the plastic right out if the FWF. Regardless of what Lycoming or anyone else does, I'm using AN363's.

Default AN363

I used AN363 on all fw fwd and control surface attachments and linkages except where castle nuts were specified.

Keep the rod end bearings lubed because Aurora rod end bearings need it.

If it calls for them, they have to be used.

If what calls for them? If you are saying builders can't deviate from the plans then we probably need to ground the entire RV fleet

One of the things I find fascinating is the difference between a Cherokee 180 and the RV-7A. Pretty much the same engine (mags, carb, etc.).

FWIW - the Cherokee does not have cotter pins on the engine mount hardware.

Default No, Walt.

I am far from being the smartest one on the List or anywhere else for that matter.
I was simply stating that if a drilled bolt and castellated nut are used together, then the cotter pin is not optional.

Default Technology

I think this is a situation of seeking a solution for a problem that doesn't exist. Van's did this for a reason and has been pointed out, 8000+ flying without control surfaces dropping off.

One of the other interesting controversies is the lace cord vs. zip ties. Many think that lace cord is the only way to go. I see no issues with zip ties but I like the looks of nicely done lace cord.

I was talking to one of the mechanics for our helicopters. He's been with the company for lots of years. I asked why everything is zip tied now instead of lace corded. He said back when lace cord was the only option. Now we have all sizes zip ties for all temperature ranges, stand offs, spacers etc..... He said nothing wrong with lace cord but technology has changed.
