Almost certainly not true. Even if the engines had failed (which the video evidence does not strongly support), the pilot can maintain control and land, even if it's short of the airfield. This is a far better outcome than a stall/spin, which the video does strongly support. The aircraft is shown in an extreme nose-high attitude prior to spinning in, which is strongly indicative of a stall. Stall/spins are rarely survivable, whereas a controlled off-field landing often is, depending on terrain. Yes, I am a pilot.
