On Wednesday, March 20th, an American Airlines flight bound for Philadelphia, Pennsylvania, in the United States suffered a bird strike shortly after takeoff from Boston, Massachusetts.

Bird strikes, a frequent hazard in the aviation industry with an average of about 50 occurrences daily, can pose significant risks to flight safety. While most incidents are managed without major issues, there are times when the severity of the strike leads to emergencies, as was the case with this flight.

The flight

American Airlines Flight AA-1146, a daily service between Boston Logan International (BOS) and Philadelphia International Airport (PHL), was abruptly interrupted by the bird strike. The flight, which typically takes around 1 hour 20 minutes to complete, was only a fraction of its way into the 280-mile (450 km) journey when it had to turn back.

The aircraft used for this particular flight was the Airbus A319-100, registration N762US, equipped with CFM56 (5B6/P) engines. According to Ch Aviation, the aircraft is 23.4 years old. It was delivered to US Airways on November 27th, 2000. As of December 31st, 2023, the aircraft had completed 61,658 hours and 38,557 cycles. American Airlines puts an average of 2,655 hours per year on the aircraft.

According to FlightAware, the aircraft took off at 12:22 local time from Runway 22 at BOS. Two minutes after takeoff, the crew asked to level off at 6,000 ft after experiencing a compressor stall on one of the engines. They also noticed the smell of smoke in the aircraft.

Passengers on the aircraft reported flames and smoke coming out of the engine. The pilot then subsequently reported a bird strike to ATC.

According to Aviation Herald, the crew maintained altitude for another six minutes and requested a long final to land, during which time they went through their SOPs and checklists. The aircraft began to descend from 6,000 ft nine minutes after the initial takeoff and safely landed 11 minutes later on Runway 22.

The entire flight lasted a total of 20 minutes, from takeoff to landing.

Aftermath

American Airlines used an Airbus A321neo (-200N), registration N467AL, from Miami International Airport to complete the flight. The flight was delayed for 10 hours, after which the replacement aircraft departed for Boston at 22:33 local time and reached Philadelphia at 23:40.

After the A321neo completed the delayed flight, another A319 was used to service the route in the past three days. According to FlightAware, the original aircraft has not flown since the incident three days ago and is undergoing maintenance.

Bird strikes

As mentioned, bird strikes are part and parcel of flying. Airports do all they can to reduce the possibility of them, but nature cannot be stopped. The majority of bird strikes, about 65%, cause little to no damage to aircraft.
