What happened
Following its approach and landing at Tempelhof Airport, the four-engine aircraft experienced significant difficulties in decelerating to a halt within the remaining runway distance. The aircraft was unable to stop before the end of the usable pavement, leading it to overrun the runway boundaries. During this sequence, the airframe struck obstacles on the ground. The impact and subsequent events caused the aircraft to catch fire, coming to rest in flames. The structure was destroyed by the fire. All four individuals on board sustained injuries during the incident.
Findings
The primary operational issue identified was the failure of the aircraft to stop within the available distance after touchdown. This resulted in a runway overrun that led to a collision with ground obstacles and a subsequent fire. While specific mechanical or environmental contributing factors are not detailed in the provided source, the sequence confirms that braking performance or stopping distance calculations were insufficient for the conditions present at the time of landing.
