The pilot reported that approximately one minute after takeoff, the emergency medical service helicopter experienced a left yaw. The nurse and paramedic, who were seated in the back, reported hearing a 'pop.' The number 1 engine-out indicator light illuminated, the pilot reduced the throttle to flight idle, and he made a turn toward the airport to land. The pilot stated that the number 1 engine-fire indicator light illuminated and he armed and discharged the fire extinguisher bottle. An emergency landing was made and the pilot and passengers were able to evacuate without further incident. Postaccident examination revealed that the engine air inlet duct on the left engine had collapsed internally due to delamination. A service bulletin addressing this issue had been complied with.
