1. General
A. The tail skid is checked for tip wear and compression of energy absorber. The tail skid should
also be checked for structural integrity, security of mounting and bonding wires.
2. Check Tail Skid
A. Check indicator clip for security.
NOTE: When energy absorber has been crushed more than 3-1/2 inches (2-1/2 inches of ring
spring compression plus 1 inch of crushed cartridge), the indicator clip will have
sheared the rivets and indicate need for replacement of energy absorber cartridge.
See 32-71-71.
