An Airbus A321-211 with registration D-AIAC operator took off from of runway 22 at Bourgas Airport, Bulgaria, performing flight DE1707 to Leipzig, Germany. During the initial climb, at altitude 1500 ft with a speed of 160 kts, the aircraft suffered a bird strike and the left engine lost significant power with high vibrations. The crew continued climbing to 4000 feet, declared an emergency and decided to return and land back at Bourgas. After performing the appropriate checklist, they were vectored for ILS approach to runway 22 and landed safely.

Based on the analysis performed, the Commission points out that the serious incident resulted from the following causes:
The ingestion of a large bird, most probably a Short-toed Eagle, into the left engine during initial climb, causing mechanical damage to the inlet and to the fan rotor, which led to a loss of the left engine thrust.
As the main contributing factor for the realization of the event, the Commission takes the existence of a big bird’s natural habitat in the area of Burgas Lake, which is situated along the flight trajectory of the aircraft that take off from RWY22 of Burgas airport.
