Narrative:
The Tupolev Tu-204-100C was destroyed by on board fire at Hangzhou Xiaoshan International Airport (HGH), Zhejiang Province, China.

Loaded with around 19.4 tons of general cargo, the aircraft was preparing to depart on a flight to Novosibirsk-Tolmachevo Airport, Russia. During pushback, the first officer taking the right seat pressed the test botton of the emergency oxygen mask on his side according to the pre-flight checklist. Second later, with a bright flash, the cockpit's right side suddenly burst into flames. Unable to put down the rapidly growing fire with the fire extinguisher on board, the eight crew members were forced to evacuate after only three minutes. Three people sustained slight injuries when they jumped down the plane. Firefighters were only able to quench the fire after four and a half hours.

Probable Cause
The investigation team believes that, the initial fire area was inside the console on the right side of the cockpit, and the origin of fire was located behind the audio control panel, in front of the oxygen shut-off and reducing device, and above the regulator control units. The most probable cause of fire is that the crew oxygen system components inside the right-hand console malfunctioned and resulted in oxygen leakage, and then the leaking oxygen formed an ephemeral oxygen-rich environment in the confined space. The considerable heat generated or emitted from the aircraft components and systems in this space ignited the combustible materials in the oxygen-rich environment. The leaking oxygen exacerbated the development and spread of the fire resulting in the substantial damage to the aircraft.
