Narrative:

The flight attendants and cabin were prepared for landing. We learned from the cockpit that it was not certain if our landing gear was down. A fly-by from another aircraft confirmed the gear was down. The compartment door on the right, which opens to release the gear, had also remained down. Apparently, the gear had not locked. The captain informed the cabin crew that the right side could be unstable upon touchdown and the aircraft could shift to the right. We landed safely. We did not taxi due to the instability of the gear. Also, the door that had remained open was dragging and creating sparks. We evacuate/evacuationed using a ramp stand at the forward entry door.
