Mumbai: Two Air India planes were struck by intense air turbulence this week, damaging the aircraft though, the passengers were safe.

An Air India plane carrying 172 passengers suffered "minor" damages after it hit air turbulence on Friday on the way to Kochi from Thiruvananthapuram, but landed safely, the PTI reported on Saturday.

No injury to any passenger or crew has been reported, an official said. The safety department of Air India has carried out a detailed investigation.

"Air India's Delhi-Trivandrum-Kochi flight A1467 hit air turbulence when it was on the way to Kochi from Trivandrum. Though no injury has been reported, the A321 aircraft suffered minor damages. It was grounded immediately after landing for inspection. Due to this, the return flight was delayed by nearly four hours," the PTI quoted an Air India official.

Meanwhile, people with direct knowledge of the matter said another Air India plane from Delhi to Vijayawada with 174 passengers hit severe bad weather on 17 September. When contacted, an Air India spokesperson said the matter was not reported to the airline.
