A ram air turbine assembly 14 comprises a movable support structure 24 attachable to a fixed structure 40 and a turbine 26 mounted to the movable support structure. The turbine includes at least one turbine blade 28 and a drive shaft driven by the turbine blade. The assembly further comprises a release pin 34 movable between an engaged position that prevents rotation of the drive shaft and a released position that allows rotation of the drive shaft. A release lever 44 is provided and is movable responsive to the position of the release pin wherein the release lever comprises a cam track 48. A pawl 52 includes a cam pin 50 which is movable within the cam track between a clearance position and a locking position in response to a position of the release lever. A lock is engaged by the pawl when the pawl is in the locking position to prevent movement of the ram air turbine assembly whilst in the stowed position.
