1. A frangible detent pin comprising:
a base configured to be secured within a bore, the base comprising an outer portion and an inner portion;
a pin head, wherein the pin head and the base are interconnected through a frangible connection; and
an elastic member configured to bias the pin head away from the base,
wherein the frangible detent pin has a rigid stage in which the pin head is rigidly positioned relative to the base and a spring-loaded stage in which the pin head is moveable relative to the base under a compression load between the pin head and the base,
wherein the frangible detent pin is configured to transition from the rigid stage to the spring-loaded stage in response to the compression load exceeding a predetermined threshold sufficient to cause the frangible connection to fail, and
wherein the frangible connection comprises a connection between the outer portion and the inner portion that is configured to fail upon the compression load exceeding the predetermined threshold.
