The Civil Aviation Authority of Vietnam (CAAV) has required relevant units to apply measures to keep birds and other wild animals away from airports because as many as seven bird hits have led to aircraft maintenance in the last ten days.
Following a flight from Da Lat in the Central Highlands province of Lam Dong to Ho Chi Minh City on April 25, engineers found a dead bird inside an engine of the Airbus A321, according to the CAAV.
The next day, blood was found on the tip of a Boeing 787 that had just flown in from Hanoi to Ho Chi Minh City.
The captain of flight QR8972 from Doha, Qatar to Ho Chi Minh City also reported a collision with a bird on the runway on April 27.
Blood was found on several parts of the A321 on April 29 after it flew from Tuy Hoa City in south-central Phu Yen Province to Ho Chi Minh City.
The plane had to be grounded for maintenance.
On the next morning, flight VJ360 from Ho Chi Minh City to Da Lat was delayed for two minutes to wait for airport staff chasing swallows away from a runway.
On May 1, after another Airbus A321 carried passengers from the southern island of Phu Quoc off Kien Giang Province to Ho Chi Minh City, technicians also detected blood on its hull.
On May 3, blood was found on the hull of a plane after it traveled from Phu Quoc to Ho Chi Minh City, resulting in additional maintenance on the aircraft.
The CAAV said birds have been slamming into planes more often in recent months.
Airports that have frequently encountered such incidents include Tan Son Nhat International Airport in Ho Chi Minh City and those in Da Lat and Phu Quoc.
On Thursday, the civil aviation authority requested relevant units to chase birds and other wild animals away from airports, especially Hanoi’s Noi Bai and Ho Chi Minh City’s Tan Son Nhat.
