Technically these are not thrust reversers, they are called thrust attenuators. They do not reverse the exhaust flow, and therefore are not certified to FAR 23.933. On the 525 (CJ1) and 525A (CJ2) they are hydraulically actuated and they deflect the flow outward. They are hinged at the front of the black attenuator, and the aft portion moves outboard - just like the cabin entry door.
On the newer 525B (CJ3) recently certified, the thrust attenuators were not included in the design for two reasons. One - the CJ3 engine is FADEC controlled and the lower idle thrust settings means slower taxi speeds. Two - the CJ3 being heavier does not coast as far when thrust is at idle.
There aren't any CJ3 photos in the database yet. About 10 have been delivered so far. As a matter of fact Harrison Ford, the actor, picked up 525B S/N 9 last week.
