Narrative:

Rotated tire -- it moved freely, there was no side play. Verified torque, safety bolts installed, hub head installed. Asked mechanics if spacer was installed, he said yes. Checked for threads checked ok. Tire was already on axle when I got to the aircraft. Became aware later that spacer was missing. Damage occurred.
