Common Parts Questions — Piper PA-28 Cherokee / Warrior / Archer
PA-28 annuals routinely flag wing spar attach bolts (NAS6606 and NAS6608 series), control cable bracket AN3 and AN4 bolts, and aileron hinge pin hardware. AN960 and AN970 washers get replaced whenever disturbed. Keep a stock of AN365 locknuts — they're one-time use per FAA guidance.
Yes. Our NAS6606 and NAS6608 close-tolerance bolts are common PA-28 spar attach sizes. These are safety-critical and require valid 8130-3 documentation, which is included. We recommend your A&P verify torque and stretch before reinstallation.
The variants share the same airframe design and use the same AN/NAS bolt families. The primary differences are in the engine mount (more AN5 hardware on higher-HP variants) and the flap actuation hardware (Archer added electric flaps). Consult your specific model's IPC.
