The four pilots of the Asiana jet that crash-landed in San Francisco are being treated for psychological trauma and injuries caused by the accident, South Korean officials said Wednesday.

The Land, Infrastructure and Transport Ministry officials said the pilots have been hospitalized following medical checkups after returning home over the weekend.

Asiana Flight 214 crashed July 6 at San Francisco International Airport, killing three and injuring dozens.

The pilots underwent questioning by the U.S. National Transportation Safety Board and South Korean investigators while in the United States.

South Korean officials plan to conduct a separate interview with them. The ministry officials said that could begin as early as Friday if the doctors allow it.

The officials gave no further details and spoke on condition of anonymity, citing department rules.

Meantime, Asiana Airlines said Wednesday it no longer plans to sue a San Francisco TV station over the use of racially offensive names.

The South Korean air carrier said that KTVU-TV has already apologized for using fake names for the four pilots.

Asiana said it wants to focus on supporting passengers and families of the dead and injured passengers.

Last week, an anchor for KTVU-TV read the fake names on air _ apparently someone's idea of a prank to use fake Asian-style names that sounded out distress calls and curse words. The anchor apologized after a break.

Asiana earlier said the report seriously damaged its reputation. It said Monday that it would sue the TV station to respond to the racially discriminatory report that disparaged Asians.
