Abstract

A thrust reverser (110, 112) is operated hydraulically but controlled by an independent electrohydraulic lock (310, 312). The electrohydraulic lock (310, 312) comprises a hook (Figure 4: 410) which is connected by a non-rigid link (Figure 4: 416, 418) to a piston (Figure 4: 422) which can be locked by a solenoid operated latch (Figure 5: 518).
