Flight International reported that the fire in the engine spread to the underbelly and fuselage due to a crosswind as the aircraft stopped on the runway.
Shades of the British Air Tours Boeing 737-200 accident at Manchester where the effect of the reverse thrust plume of the affected engine atomised escaping fuel from a ruptured fuel tank and increased the severity of the conflagration. When that aircraft turned off the runway and stopped on the taxiway, the five knot now crosswind blew the flames against the fuselage with disastrous results.
