The F27 crash in Pakistan
This accident seems very similar to the fatal F27 accident in Canada, and the non fatal HS748 accident at Stansted. In both cases, the Dart engine had an uncontained failure (the engine exploded) immediatly after lift off leaving the failed engine in two halves. The Canadian F27 crew continued with the departure with an uncontrollable aircraft and crashed as they tried to return to the airfield. The Stansted HS748 had the benefit of a long runway and chose to land back on, albeit over-running the runway resulting in no injuries to passengers or crew. There is a history of such failures of the Dart engine, the failure happening whilst the aircraft was still on the ground. The AAIB took Rolls Royce to task in the Stansted report and many modifications and more detailed inspections were recommended
