Tail Post

ENGINEERING CHANGE

The tail post insert has been increased in length and rosette weld above the rudder hinge attach bushing. Due to twisting forces on the tailwheel rod spring, cracking can otherwise occur at the bushing and tail post. Problem was caused by poor welding of bushing into tail post, and rough off Airport use.
