What happened
On September 23, 2016, the crew of a landing Boeing 757-200 reported a bird strike to air traffic control at Warsaw Chopin Airport (EPWA). Following the incident, the airport's operational duty officer conducted an inspection of the runway area near the aircraft's touchdown point, where a dead bird was discovered. Subsequent inspection of the aircraft revealed impact marks on the windshield on the right side of the fuselage.
The investigation
The investigation, conducted by the airport management, focused on the presence of wildlife on the airfield and the physical evidence found on the aircraft and the runway. The inspection of the runway surface led to the removal of the carcass, after which the runway was cleared and returned to flight operations.
Findings
The investigation established that the incident was caused by the presence of a black redstart (Phoenicurus ochruros) on the landing path of the aircraft.
