This is what happens if an airplane suddenly raises the gear when it starts to land

Last year, an event in Saarbrucken (Germany) helped answer a question regarding flying a plane: what would happen if the plane pulled its grounded wheel into the cabin when preparing to land on the plane? land?

Accordingly, one had to drag a Bombardier Dash8-Q400 into the house so that the aircraft body could be polished. A study conducted regarding the mechanism of grounding wheels shows that while other aircraft have mechanical locks to prevent them from being lifted (pulled into the fuselage) when the WOW sensors (Weight on Wheels is activated, the Dash8-Q400 is slightly different.

Normally, the grounding wheel at the tip of the plane is the first thing to lift off the ground when the plane takes off.(Illustration).

Just a WOW sensor reports that the plane is flying in the air, the plane itself will understand it is hovering despite the fact that it is not. In order for WOW sensors to report so, a gear lever in the cockpit must be pulled up. For some unknown reason, this need remains in the pull-up position even though the aircraft is parked on the beach. Normally, the grounding wheel at the tip of the plane is the first thing to lift off the ground when the plane takes off, the WOW sensor sends a signal that starts to pull this wheel into the fuselage.

The surface beneath the fuselage was badly damaged.

Because the Dash8-Q400 has only two wheels in the back and when these two wheels are pulled into the fuselage, this huge vehicle has nowhere to hold it. The plane slammed into the ground, slipping on the runway and stopped only when it reached the end of the road. Fortunately, no passengers or crew were injured. Soon after, people had to immediately change the mechanism of this Bombardier.
