A latch assembly for a door pivotally mounted to a surrounding structure for pivotal movement along a common pivotal axis between a first opened position, a second opened position, and a closed position, the latch assembly comprising:
- a latch keep carried by one of the door and the structure and having a strike seat in which a strike may be removably received;
- a latch carried by the other of the door and the structure and having a catch configured to engage the strike;
- and
- a cable having a first portion secured to the other of the door and structure and a second portion carrying the strike;
- wherein when the strike is located within the strike seat, the catch is configured to engage the strike and hold the door in the closed position thereby ensuring a coupling of the cable between the door and the structure,
- when the strike is located within the strike seat, the door is prevented from opening beyond the first opened position along the common pivotal axis so that the door functions as a pressure relief door, and
- when the strike is not located within the strike seat, the door is enabled to open beyond the first opened position to the second opened position along the common pivotal axis so that the door functions as an access door.
A door and latch assembly for an aircraft engine, comprising:
