From the report.
The engine failure
Following a normal takeoff, the crew retracted the landing gear and flaps. The crew reported that, while maintaining 250 kts in the climb and passing 7,000 ft above mean sea level (AMSL), they heard two, almost coincident ‘loud bangs’. The PIC immediately selected altitude and heading hold on the autopilot control panel, and the FO started his chronometer.
Not too diffucult to understand surely!
