does anyone know the manufacturing process of the spindle?  i would imagine the blank is initially forged, then the rest is machined,,, machined threads ?  i don't think most parts (except for bolts) have rolled threads---which are much stronger, because of the "grain flow"  who on here works for Enstrom?

Wow, these inspections no doubt saved a few lives. 20% is a much bigger number than I expected to see.

Updated EAD to 1,500 TIS, and and SDB for every 300 hours after. Most 480's and 480B's have TT straps, and are exempt.
