A Boeing 737-322 (WL) operated by SCAT sustained substantial damage in a ground fire accident at Aktau Airport (SCO), Kazakhstan.
Flight DV742 arrived from Astana, Kazakhstan at 18:18 hours local time.

At that time a fire broke out in the forward fuselage. Airport fire fighting services extinguished the fire.
The fire occurred in the area of the front luggage hold, from STA 380 until STA 440 and between S-24 R and S-18 R stringers.

Probable Cause:

The cause of the fire and the fire on board the aircraft, was the spontaneous destruction of the oxygen hose with compressed oxygen, used for filling the aircraft using a ground source with pressurized oxygen.
Contributing causes of fire and the fire were:
Instant spontaneous combustion of dynamically disturbed and oxygen-enriched air-flow in a fine dust environment in the front luggage compartment in the area of the aircraft oxygen bottle due to constant pressure of oxygen coming from an open oxygen cylinder.
