Vietnam Air Petrol Company (Vinapco) has suspended three more workers for their involvement in a crash between a plane and a truck at Ho Chi Minh City's airport last week, VnExpress reported Tuesday.
Vo Quoc Khanh, head of the filling team at Vinapco's Southern Air Petrol Factory, and his subordinates Nguyen Xuan Phu and Tran Dinh Tuat, have been held "directly responsible" for the incident at Tan Son Nhat International Airport last Tuesday, according to the news website.
Vinapco previously suspended Le Van Dung, who drove the tank truck that day, and technician Le Doan Tho.
Investigations showed that Dung failed to brake when he drove the vehicle off the runway after filling the plane with gasoline. His truck subsequently crashed into a Vietnam Airlines ATR-72 aircraft, damaging the plane's tail.
The driver also had his license revoked, the news source said.
The accident delayed the flight from HCMC to the southernmost province of Ca Mau.
On May 9, another Vinapco tank truck collided into a Vietnam Airlines Boeing 777, severely damaging the plane's engine and spilling gasoline on the runway.
The incident happened at 10.30 p.m. when the plane was about to take off for Frankfurt from Tan Son Nhat.
In related news, a passenger plane operated by Vasco, a unit of Vietnam Airlines, had to turn around and make a landing 10 minutes after it took off from Tan Son Nhat on Tuesday afternoon when smoke began billowing into the cabin and the interior's temperature surged.
The plane was headed for the central province of Phu Yen.
The ATR-72 aircraft also made an emergency landing 15 minutes after taking off from Phu Yen Tuy Hoa Airport for HCMC last Tuesday due to the same problem.
