Narrative:

Left engine ingested preconditioned air hose after parking. Arrived ord and assigned a gate. Waited for agent to raise jetbridge and then parked with 2 wing walkers and guide man. After brake was set and engines at idle, we shut down the right engine and as it spooled down we noticed a significant airframe vibration. We then shut down the left engine and noticed the agent on the jetbridge looking at the left side of aircraft. After opening the cockpit window and looking at the left engine, I saw that it had ingested a yellow preconditioned air hose extension (ie, on a portable cart). It's possible that the high winds in the gate area blowing from the left side of the aircraft may have been enough to move the air hose near the engine intake area after parking. No abnormal left engine indications were apparent after shutdown. Passenger deplaned normally.

Title: B767 CREW INGESTED AN AIR CONDITIONING HOSE WHILE BEING MARSHALED IN TO THE GATE.

Narrative: L ENG INGESTED PRECONDITIONED AIR HOSE AFTER PARKING. ARRIVED ORD AND ASSIGNED A GATE. WAITED FOR AGENT TO RAISE JETBRIDGE AND THEN PARKED WITH 2 WING WALKERS AND GUIDE MAN. AFTER BRAKE WAS SET AND ENGS AT IDLE, WE SHUT DOWN THE R ENG AND AS IT SPOOLED DOWN WE NOTICED A SIGNIFICANT AIRFRAME VIBRATION. WE THEN SHUT DOWN THE L ENG AND NOTICED THE AGENT ON THE JETBRIDGE LOOKING AT THE L SIDE OF ACFT. AFTER OPENING THE COCKPIT WINDOW AND LOOKING AT THE L ENG, I SAW THAT IT HAD INGESTED A YELLOW PRECONDITIONED AIR HOSE EXTENSION (IE, ON A PORTABLE CART). IT'S POSSIBLE THAT THE HIGH WINDS IN THE GATE AREA BLOWING FROM THE L SIDE OF THE ACFT MAY HAVE BEEN ENOUGH TO MOVE THE AIR HOSE NEAR THE ENG INTAKE AREA AFTER PARKING. NO ABNORMAL L ENG INDICATIONS WERE APPARENT AFTER SHUTDOWN. PAX DEPLANED NORMALLY.
