A system for detecting a fault in a locking pin for use in an aircraft includes the locking pin; means for receiving a static air temperature; and a controller; wherein said locking pin comprises an internal heater element and at least one internal temperature sensor provided therein. The system also includes means for transmitting said measured temperature sensor information from said at least internal temperature sensor and said static air temperature information to said controller. The controller is configured to compare the static air temperature information with said locking pin temperature sensor information and determine if a difference between the measurements is above a static v. internal temperature threshold value.
