American Airlines Flight 96 was a regular domestic flight operated by American Airlines from Los Angeles to New York via Detroit and Buffalo. The flight was operated with a McDonnell Douglas DC-10. All of the other portions of the cargo holds had holes cut into the cabin floor above the cargo areas.
Only the rearmost portion of the cabin lacked these holes, and it was that portion that failed. In the case of a pressure loss on either side of the floor, the air would flow through the vents and equalize the pressure, thereby eliminating any force on the floor.
He managed to get the latch to lock only by applying force with his knee, but he noticed that the vent plug (see below) was not entirely closed. Lastly, there was an indicator light in the cockpit that would remain on if the door was not correctly latched.In theory, motor failure on the plane could not present a problem because it would fail to close the locking lever. Other incidents have occurred where controls were not functioning correctly prior to take-off, either due to maintenance or pilot error, and controls can become inoperative from extreme weather conditions. Although the vent door remained partially open, it closed enough to cause it to "blow shut", and thereby allow pressurization of the cargo hold.

In spite of this, the cabin crew immediately attempted to ensure the oxygen masks had deployed properly, but having occurred below the 14,000The aircraft returned to Detroit, but, when the crew set the flaps to 35 degrees for landing, the aircraft stabilized in a 1,900The problem that caused the accident was immediately obvious, as the rear cargo door was missing and had caused severe damage to the left horizontal stabilizer as it blew off. Yet all of these indicators shared a The cabin floor failure was also a matter of poor design. It was only the combination of all of these failures that allowed the accident to happen.
The cause was traced to the cargo door latching system, which had failed to close and latch the door completely without any indication to the crew that it was not safely closed. On June 12, 1972, American Airlines Flight 96, a DC-10, broke through a spotty cloud layer over the Canadian industrial city of Windsor, Ontario. AMERICAN AIRLINES FLIGHT 96. Additionally, the handle moved a metal plug into a vent cut in the outer door panel; if the vent was not plugged the door would not retain pressure, eliminating any force on the door. Its airframe was broken up at Several aviation incidents and accidents have occurred in which the control surfaces of the aircraft became disabled, often due to failure of hydraulic systems or the flight control system. McDonnell Douglas instituted a number of minor changes to the system in an attempt to avoid a repeat. If the latches were not in their correct positions, the pins could not enter the holes, and the operating handle on the outside of the door would remain open and visually indicate that there was a problem. He stated that he closed the door electrically, and waited for the sound of the actuator motors to stop. Ukraine Airlines Boeing 737-800 crashed shortly after taking off from Tehran on Wednesday, killing everyone aboard. In their locked position, pressure on the door presses the latches further shut, and no force is transmitted into the actuator system that closes and opens them. He brought this to the attention of a mechanic, who cleared the flight. Iran, US, or fog of war: Who is to be blamed for Ukrainian jet disaster that killed 176.
On 30 May, McDonnell Douglas issued Service Bulletin 52-27, DC-10 SC 612, which called for the upgrading of the electrical wiring that drove the latches because "Three operators have reported failure of the electrical latch actuators to latch/unlatch the cargo doors. But, she said, managers at American Airlines denied her requests due to “image standards” and they made passengers feel uncomfortable .
