What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) The aircraft was cleared for takeoff on runway 31C. The pilot taxied slightly left of the assumed centerline lighting position, and held there while the cabin was checked. Brakes were held as power was increased to takeoff power. Brakes were released and aircraft headed down the runway. Airspeed and engine gages were checked. Shortly thereafter the pilot heard a single thump, he thought he ran over a recessed centerline light. Aircraft instruments were indicating normal and directional control of the airplane was normal. The pilot positioned the aircraft just to the left of what he thought were the centerline lights for the rest of the takeoff. The flight was uneventful until reaching sioux falls where they encountered a bird strike on final approach. The aircraft was inspected for the bird strike damage, and that is when it was discovered that there was a hole on the underside of the right flap. Midway tower was called and they inspected the runway where they found a broken runway light and a sign was knocked down.
As the FAA filed it
(-23) THE AIRCRAFT WAS CLEARED FOR TAKEOFF ON RUNWAY 31C. THE PILOT TAXIED SLIGHTLY LEFT OF THE ASSUMED CENTERLINE LIGHTING POSITION, AND HELD THERE WHILE THE CABIN WAS CHECKED. BRAKES WERE HELD AS POWER WAS INCREASED TO TAKEOFF POWER. BRAKES WERE RELEASED AND AIRCRAFT HEADED DOWN THE RUNWAY. AIRSPEED AND ENGINE GAGES WERE CHECKED. SHORTLY THEREAFTER THE PILOT HEARD A SINGLE THUMP, HE THOUGHT HE RAN OVER A RECESSED CENTERLINE LIGHT. AIRCRAFT INSTRUMENTS WERE INDICATING NORMAL AND DIRECTIONAL CONTROL OF THE AIRPLANE WAS NORMAL. THE PILOT POSITIONED THE AIRCRAFT JUST TO THE LEFT OF WHAT HE THOUGHT WERE THE CENTERLINE LIGHTS FOR THE REST OF THE TAKEOFF. THE FLIGHT WAS UNEVENTFUL UNTIL REACHING SIOUX FALLS WHERE THEY ENCOUNTERED A BIRD STRIKE ON FINAL APPROACH. THE AIRCRAFT WAS INSPECTED FOR THE BIRD STRIKE DAMAGE, AND THAT IS WHEN IT WAS DISCOVERED THAT THERE WAS A HOLE ON THE UNDERSIDE OF THE RIGHT FLAP. MIDWAY TOWER WAS CALLED AND THEY INSPECTED THE RUNWAY WHERE THEY FOUND A BROKEN RUNWAY LIGHT AND A SIGN WAS KNOCKED DOWN.
