CSeries engine fire that delayed production blamed on technical malfunctions
All Bombardier aircraft received new engines following 2014 incident
An engine fire two years ago that grounded Bombardier's CSeries test aircraft fleet has been blamed on a series of technical malfunctions.
In a report released today by the Transport Safety Board, it was determined that the engine had been shut down without sufficient time for its internal temperatures to lower which created a domino effect of problems and the subsequent engine fire.

In May 2014, pilots and engineers were testing a Bombardier CS100 at the Mirabel Airport when smoke and fire erupted in the aircraft's left engine.
An emergency was declared and all personnel evacuated the aircraft. Firefighters from Mirabel airport responded to the call.
Following the incident, all Bombardier aircraft received new engines. It added to the delays the CSeries experienced before being ready for market.
The investigation found that the makers of the engine, Pratt & Whitney, had issued instruction for the engine's proper cooling. Bombardier's interpretation of the instructions however led to the engine enduring too many hot shutdowns.
Following the grounding of the C Series test aircraft fleet Pratt & Whitney proposed a plan to prevent the hot shutdowns which led to the fire.
