Narrative:Delta flight 1691, an Airbus A320-211, N331NW, experienced a bird strike during initial climb after departure from Minneapolis-St. Paul International Airport (KMSP), Minnesota. There were no injuries to the 150 passengers and crewmembers onboard and the airplane was substantially damaged.
According to the flight crew, a flock of "50-100" large white birds, possibly geese, appeared in front of the airplane during initial climb. The first officer, who was the pilot flying, increased the rate of climb to attempt to avoid the flock, but at least one bird made impacted the aircraft. After striking the bird, the flight crew received an Electronic Centralized Aircraft Monitor message for loss of cabin pressure and the right side airspeed indication became erratic. The flight crew declared an emergency and made an uneventful landing back at KMSP.
Examination of the aircraft after landing revealed substantial damage to the forward pressure bulkhead and minor damage to the right engine.
PROBABLE CAUSE: "In-flight collision with birds during initial climb, which resulted in substantial damage to the aircraft."
