Cross Reference

[Firstflight]

I had a bad pulley on my Cherokee trim tab cables. So I got a new pulley but wanted to replace the bolt and the bushing as well. The 63900-21 bushing does not appear in anyone's parts database. Is there a way that I can access a cross reference list to an AN or
NSN?

I'd email or call Aircraft Spruce with the part numbers. Surprising what they have and have been able to cross reference for me. The bushing might be a Piper specific part from a salvage yard or new from factory. Personally I prefer new when it comes to wear items.

Thanks. That's an easy thing to try. It's totally possible that it's not piper specific, as it didn't have a W by it in the parts list. Then again, they didn't include an alternate part number, which is often included with most standards. And I agree that this needs to be "new."
