1. A main strut for an aircraft landing gear assembly, the main strut comprising:
a tubular structure having a central axis and at least one open end;
at least one pintle pin arranged at least partially within the at least one open end of the tubular structure and moveable along the central axis between a retracted position and an extended position, wherein in the extended position a portion of the at least one pintle pin protrudes from the at least one open end of the tubular structure for engagement with a pintle lug and in the retracted position the at least one pintle pin is withdrawn into the tubular structure for disengagement with the pintle lug;
a retraction mechanism disposed within the tubular structure and coupled to the at least one pintle pin, the retraction mechanism arranged to convert a rotary input motion into linear motion of the at least one pintle pin along the central axis to drive the at least one pintle pin between the extended position and the retracted position.
