The airline later reported that airline staff reached Goose Bay and now takes care of the passengers. Two flights were dispatched to Goose Bay to pick up the passengers and take them to Los Angeles. An Air France Boeing 777-300 registration F-GZNO arriving from Montreal,QC (Canada) reached Goose Bay at about 02:50L (05:50Z) and departed Goose Bay for Atlanta,GA (USA) at flight AF-4080 at 06:55L (09:55Z). An additional Boeing 737-300 registration C-GNLQ leased in from Nolinor arrived 3 hours ago and already departed Goose Bay as flight NRL-580 to Winnipeg,MB (Canada) and further to Los Angeles.
The passengers disembarked via stairs and boarded the replacement aircraft.
On Oct 1st 2017 the Canadian TSB reported they have dispatched a team of investigators to Goose Bay to collect evidence and assess the occurrence.
On Oct 3rd 2017 the French BEA announced, that the Danish Aviation Authorities (responsible also for Greenland) have delegated the investigation to the BEA. Representatives of Denmark, the US NTSB and the Canadian TSB have joined the investigation. Four BEA investigators accompanied by advisors from Airbus and Air France departed to Goose Bay on Oct 1st, NTSB investigators accompanied by advisors from Engine Alliance (General Electric and Pratt Whitney) travelled to Goose Bay. A fifth BEA investigator travelled to Ottawa for a first reading of the FDR data which confirmed the fan separation took place over Greenland. First observation of the engine suggests, the fan - the first rotating element - detached in flight dragging the air inlet with it. The damage appears to be limited to engine #4 and its immediate environment.
