A locking system for doors of a deployable aircraft landing gear system, the locking system comprising:
- a spring-biased swing arm configured to be pivotally attached to a body of an aircraft and including a roller at a distal end of the swing arm;
- wherein the swing arm is configured to engage with a portion of a first landing gear bay door to prevent the first landing gear bay door from opening;
- wherein the portion of the first landing gear bay door is a hook and the roller is configured to engage the first landing gear bay door under the hook, thereby preventing the first landing gear bay door from opening;
- wherein the roller of the swing arm is configured to be prevented from disengaging from the portion of the first landing gear bay door by a portion of a second landing gear bay door adjacent to the first landing gear bay door;
- and
- wherein the roller is configured to abut the portion of the second landing gear bay door to prevent the roller from moving out from under the hook of the first landing gear bay door.
