ABSTRACT OF THE DISCLOSURE A releasable self-resetting cargo hook for heli- copters and other aircraft for supporting suspended loads. The cargo hook apparatus includes a pivotally supported load arm maintained in its load supporting condition by a pivotally mounted latch arm whose posi- tion, in turn, is controlled by a pivotally mounted latch. The position of the latch is determined by a pivotally mounted lock arm lever whose normal position is determined by a stop pin and which is operated by a release mechanism. The interconnection between the latch and lock arm lever is through a cam slot defined on the latch receiving a lock arm lever follower, and the cam slot-follower relationship prevents impact forces imposed on the cargo hook structure from inadver- tently producing lock arm lever rotation and latch move- ment.
