Negaduck's plane is one of many, many vehicles Negaduck possesses and barely uses.
Like with all of Negaduck's color-coded toys, it's unknown whether he gets the plane from the Negaverse or had it built within the dimension he uses it in. The fact it is identical to the Thunderquack but for the colors points at the former, but doesn't rule out the latter.
Negaduck's plane and the Thunderquack are locked in aerial combat. Darkwing Duck drops himself on the other plane's windshield, so Negaduck opens the cockpit to launch him off. Then he parachutes out in the wrong expectation the heroes will lose track of him.
