Narrative:

We were reassigned to an aircraft that had an inop APU. Boarding was complete and the captain and I completed the preflight and push-back checklists. I then ran the ground air start checklist referencing the QRH. The captain coordinated with ground personnel for engine start and high pressure air to be turned on. Ground personnel started the high pressure air and cleared us to start engine #1. I started engine #1 per the ground start checklist and after stabilization and power transfer to the engine #1 generator; I completed the cleanup items on the checklist. The captain then instructed ground personnel to remove the high pressure air hose and ground power. Moments later we heard a large bang and the aircraft started to shake violently. I realized that something had been ingested into the #1 engine and immediately shut it down which also cut power to the aircraft. Ground personnel had no communication with us for the next few minutes. After reestablishing communication we instructed them to reconnect ground power and I called operations to have them bring the jet bridge back to deplane the passengers. Further investigation showed that the ground personnel failed to remove the pc air hose from the aircraft prior to clearing the #1 engine start; causing it to be sucked into the engine. Passengers were deplaned uneventfully and no injuries to passengers or ground personnel were noted.
