Lock for a trust reverser

A lock for a thrust reverser comprising a retainer member carried by a pivot pin, the pivot pin being angularly moveable between a first, locked position in which the retainer member retains a part of the thrust reverser and a second, unlocked position in which the said part of the thrust reverser is not retained by the retainer member, and a lock arrangement for retaining the pivot pin in its first, locked position, the lock arrangement comprising a lock member axially moveable between a locked position and a retracted position and cooperable with the pivot pin such that, when the lock member is in its locked position, movement of the pivot pin from its first position to its second position is prevented and, when the lock member is in its retracted position, the pivot pin is free to move, an arrangement for restricting angular movement of the lock member, and a solenoid actuator arranged to control movement of the lock member, wherein the pivot pin has an axis of angular movement about which the pivot pin moves angularly and whereby, in the event that a fault occurs in the thrust reverser system, the retainer member is moveable relative to the pivot pin in a direction perpendicular to the axis of angular movement of the pivot pin.
