D6-27370-866-EGP 15.20.31
The cartridge assembly consists of a crushable honeycomb material. When the tail
skid strikes the runway the skid moves upward and the honeycomb material
crushes. The tail skid is serviceable when the cartridge warning decal shows both
green and red. The green disappears gradually as the cartridge is crushed. When
the warning decal is all red, the cartridge must be replaced.
The shoe is what contacts the runway in the event of an over rotation. The shoe
surface displays “wear dimples” which serve as a reference for shoe replacement.
CAUTION: Cartridge assembly warning placard must be checked as soon
as possible after the tail strike. The tail skid skirt fairing may
re-extend due to gravity as time passes resulting in a reading
error on the warning placard decal.
