What happened
On October 22, 2013, at approximately 7:29 p.m., a Boeing 737-800, registration C-GOWG, operated by Sunwing Airlines, was performing a takeoff from Gregorio Luperón International Airport (MDPP) in Puerto Plata, Dominican Republic. As the aircraft began its rotation, a white bird crossed the nose of the plane, resulting in a bird strike involving the number 2 engine.
The impact caused high-frequency vibrations in the right-hand engine. The crew responded by reducing power to stabilize the aircraft and mitigate the vibrations. Due to prevailing weather conditions that prevented a return to the departure airport, the crew elected to divert to Punta Cana International Airport for an emergency landing. The flight, which was destined for Toronto Pearson International Airport, continued for approximately 30 minutes before safely landing in Punta Cana. All 180 occupants, including 173 passengers and 7 crew members, were unharmed.
The investigation
The CIAA investigation examined the aircraft's mechanical condition, the crew's performance, and the environmental factors. Investigators inspected the number 2 CFM56-7B engine and identified physical damage to the fan blades. Biological remains and bloodstains from the bird were found within the engine intake. The investigation also reviewed the flight crew's records, air traffic control communications, and the airport's bird protection program. The crew's medical and toxicological status were also verified, with no anomalies found.
