What happened
During ground operations at Chino Airport, two technicians were conducting engine tests on an aircraft parked on the apron. While the crew was positioned facing a nearby hangar, the aircraft unexpectedly moved forward, bypassing the chocks placed in front of its wheels.
The uncontrolled movement caused the plane to strike the metallic door of the hangar. The impact was forceful enough that the nose of the aircraft ended up partially inside the structure before it finally stopped moving.
Despite the severity of the collision, there were zero fatalities and no injuries were reported among the two technicians on site. However, the impact resulted in the aircraft being declared a total loss, as the damage was deemed beyond repair.
Findings
No official investigation into the specific mechanics of the movement has been released by the NTSB regarding this incident.
