An Air India passenger plane has been grounded for inspection after its power unit caught fire upon landing in New Delhi.

An Air India plane skidded off the runway at Mumbai international airport during landing, causing damage and temporarily closing the runway.

Indian officials say it's too early to draw any firm conclusions about the cause of the Air India crash.

The captain of the Air India plane that crashed last month switched off the fuel supply to both engines, according to black box recordings cited by the Wall Street Journal.

Indian airlines are instructed to inspect fuel switches on several Boeing models following a preliminary investigation into the Air India incident.

Fuel switches are typically located near the throttle, allowing pilots convenient operation and quick response to emergencies.

Two commercial pilot associations argue there's no basis to conclude human error led to the crash that killed 260 people last month.
