On August 10, 2014 at about 0605 eastern daylight time, a deHavilland DHC-8-100, N815EX, operated by Piedmont Airlines d.b.a. USAirways Express flight 4206, struck a flock of geese during the takeoff roll from Middletown Harrisburg International Airport (KMDT), Harrisburg, Pennsylvania. There were no injuries to the passengers or crew and the airplane sustained damage. The flight was operating under the provisions of 14 Code of Federal Regulations Part 121 as a regularly scheduled passenger flight between KMDT and Philadelphia International Airport (KPHL), Philadelphia, Pennsylvania.

The captain was the pilot flying and the first officer was the pilot monitoring. According to the flight crew, about 15 seconds into the takeoff roll and prior to V1, the captain observed a large group of geese flying from right to left in front of the airplane. He immediately initiated a rejected takeoff as the airplane impacted multiple geese on the front windshield and the right engine propeller, which caused a severe vibration. The flight crew shut down the right engine as the airplane slowed and returned to the gate.

Examination of the airplane indicated damage to the right propeller, a broken passenger window, and damage to the fuselage skin and stringers near the broken window.
