ABSTRACT:
An anti-deployment device and method for preventing inadvertent deployment of a ram air turbine of an aircraft during servicing or repair of turbine employ an anti-deployment pin which can be manually inserted in a support arrangement for the pin on the aircraft when the ram air turbine is in the stowed position for preventing deployment of the turbine upon release of a lock mechanism which locks the turbine in the stowed position. The pin has an elongated body with an outer, flat contact surface portion which extends in a plane that is inclined with respect to a longitudinal center axis of the pin.
