N331NW

On November 10, 2011, at about 1157 central standard time, Delta flight 1691, an A320-211, N331NW, experienced a bird strike during initial climb after departure from Minneapolis-St. Paul International Airport (KMSP), Minneapolis, Minnesota. There were no injuries to the 150 passengers and crewmembers onboard and the airplane was substantially damaged. The flight was operating as a 14 Code of Federal Regulations Part 121 regularly scheduled passenger flight from KMSP to Reno–Tahoe International Airport (KRNO), Reno, Nevada.

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.
