On Nov 17th 2015 the airline reported in a press conference, that the first officer had retracted the landing gear too early before the captain aborted takeoff causing the aircraft to settle on its belly without landing gear. The captain as well as cabin crew acted well in the course of the occurrence, the first officer however was suspended.
This begs the question: How does this happen? The gear should be protected against inadvertent retraction as long as there is weight on wheels - which is typically the case before V1 (and also a varying time above that speed). Also, to retract the gear on the DH8, one will first need to unlatch the gear lever via a thumb-operated little knob before moving it to the "Up" position, so it is rather hard to move it unintentionally. And finally, there is a huge difference in sound and also in the general setting surrounding it between the callout "Stop" (or whatever LG may use to initiate a takeoff abort) and "Positive", which triggers the next order "Gear Up".
The FDR transcript will likely be highly interesting.
