France to Lead Jet Engine Failure ProbeDavid Wagman | October 05, 2017
Danish authorities have asked the French Bureau d'Enquêtes et d'Analyses (BEA) to lead the investigation in an engine failure on an Airbus A380 super-jumbo aircraft on September 30.
The Air France flight from Paris to Los Angeles made an emergency landing in eastern Canada after one of its four engines sustained serious damage over Greenland, which is a Danish territory.
The BEA says that data contained in the flight data recorder was used to determine where the failure of engine number 4 occurred and also to mark a search area to find the parts that fell from the plane.
This area is covered with ice around 150 km southeast of the city Paamiut on Greenland's west coast.
With three other major aviation nations involved, Denmark exercised its right to delegate the main role. France had priority because that was where the plane was designed, built, registered and operated.
Canadian investigators will remain involved along with counterparts from the United States, France and Denmark.
At the request of the Danish Accident Investigation Board, a helicopter operated by Air Greenland flew over the area and spotted parts from the engine. The BEA is in contact with Danish officials to organize the recovery of these parts.
Analysis of the data contained in the flight recorders will take place at a BEA laboratory. The engine computers also will be analyzed by the component manufacturer in the United States.
The engine is based on the GE90-110B/115B core and contains a Pratt & Whitney fan and low-pressure system design. It is built by Engine Alliance, a joint venture between General Electric and Pratt & Whitney.
The aircraft involved was about seven years old.
