1. A one-way speed limiter for a power door opening system mounted in an aircraft, the one-way speed limiter comprising:
a first housing including a first wall including an outer surface and an inner surface, the inner surface defining a speed limiter receiving zone;
a second housing extending into the first housing, the second housing including a flange having an inner surface section and a second wall extending outwardly from the flange, the second wall including an outer surface portion that engages with the inner surface of the first housing and an inner surface portion that includes a stop feature;
a ball housing including a ball member is rotatably supported in the speed limiter receiving zone, the ball member selectively engaging the stop feature to generate an axial force on the ball housing;
a friction clutch disposed between the ball housing and the first housing, the friction clutch selectively retarding rotation of the ball housing; and
a motor shaft selectively rotatably connected to the ball housing, the motor shaft including a first end supported at the ball housing and a second end, the motor shaft being rotatable relative to the ball housing in a first direction and selectively rotatably constrained relative to the ball housing in a second direction to selectively engage the friction clutch.
