Advisory Circular 150/5220-23 – Frangible Connections -discusses Frangible Connections which are devices installed at airports that are designed to have minimal mass and absorb a minimal amount of energy during an impact event. In the airport environment, the goal of these objects is to not impede the motion of, or radically alter the path of, an aircraft while minimizing the overall potential for damage during an incident.
This AC covers the following types of frangible connections:
a. Fuse bolts (including frangible or neck-down bolts),
b. Special material bolts (including alloy bolts),
c. Frangible couplings,
d. Tear-through fasteners (including countersunk rivets), and
e. Tear-out sections (including gusset plates).
