Asiana said Sunday it was planning lawsuits against US transport authorities and a TV station for mistakenly confirming and airing false and offensive names for the pilots behind its fatal crash in San Francisco.

Fox network affiliate KTVU news Channel 2 in Oakland identified the pilots of the Asiana Airlines Boeing 777 that crashed last weekend as “Sum Ting Wong,” “Wi Tu Lo,” “Ho Lee Fuk,” and “Bang Ding Ow.”

KTVU cited the National Transportation Safety Board (NTSB) as its source, but quickly realised the mistake and apologised.

The NTSB later apologised for the “inaccurate and offensive names that were mistakenly confirmed” as those of the Asiana pilots - and blamed the mistake on an intern.

Asiana however said the incident had “seriously tarnished the dignity of the four pilots as well as the company”.

“We are planning legal actions against KTVU that aired the report as well as the NTSB that confirmed the names,” the air carrier said in a statement.

"...blamed the mistake on an intern."
