Claim:
A pressure relief system for an aircraft door, the door having a handle and a spine integral with the aircraft door, the spine being in mechanical communication with the handle and the pressure relief system, the system comprising: a pin member spanning laterally between a first side and a second side of at least one mount fastened onto the spine, a central portion of the pin member thus being uninhibited; a shaft mechanically connected to a door vent, the shaft having at least one forward catch member attached thereto; and a spring which is torqued or compressed by changes made in the angular position of the shaft; wherein the at least one catch member engages the pin member when activation of the handle causes the spine to be translated in a first direction a distance greater than zero, causing the shaft to rotate; and wherein engagement of the pin member rotates the shaft from an original position, causing at least one lever to rotate from an under-center position wherein the vent door is maintained in closed position to an over-center position compelling the opening of the door vent.
