The problem with low pressure in one tire on the Airbus 330-300 was detected sometime after it took off from Calcutta about 2:40 a.m., bound for Thailand, the Bangkok Post reported. The pilot requested to make an emergency landing as the plane neared Suvarnabhumi airport about 6 a.m., said Thai Airways International President Sorajak Kasemsuvan. Once on the ground, another tire was discovered to have low air pressure as well.
It was initially believed one of the plane's tires exploded, but Sorajak said the emergency landing request was actually was only made because of low tire pressure.
"The plane tire did not burst or explode on landing as reported but the left and right front tires had low pressure," Sorajak said.
The 287 passengers and crew members were uninjured in the incident, but had to wait aboard the aircraft for about an hour, Sorajak said.
"THAI will investigate the cause of under-inflated tires because the aircraft had to be inspected in accordance with international standards before leaving the [India] airport," Sorajak said.
