According to the Wall St Journal, an incident during ground maintenance testing of the Bombardier C Series jet resulted in an uncontained engine failure and has grounded the jet until an investigation is completed. Although the engine and body of the aircraft were damaged, no personnel suffered any injury.
The geared Turbofan engine (PW1500G) from Pratt & Whitney features a new fuel-saving concept that sees different parts of the engine running at different speeds. The incident is likely to cause further delays to the program that is already behind schedule.
Pratt & Whitney now face a major setback commercially, with the engine currently holding more than 5,500 orders from Bombardier, Embraer and for the Airbus A320neo series.
The company were not available for comment.
