On 29 May 2014, one of the four FTVs suffered an uncontained engine failure. Consequently, flight testing was suspended until an investigation could be completed. The incident kept Bombardier from displaying the CSeries at one of the most important aerospace events in 2014, the biennial Farnborough Airshow. In August 2014, Bombardier changed the program's management and slashed its workforce. On 7 September 2014, flight testing was resumed after the engine problem had been isolated to a fault in the lubrication system. Bombardier chairman Laurent Beaudoin stated that the CSeries was then expected to be in service in 2016.
