MINNEAPOLIS (WCCO) — Minnesota-based Sun Country Airlines faces a fine after the Federal Aviation Administration says it violated drug and alcohol screening requirements.

The FAA says at least one pilot, three flight attendants and a mechanic were not screened.

The FAA also says the airline didn’t conduct pre-employment drug tests and also didn’t wait to get the results before hiring for safety-sensitive positions.

Sun Country must now pay $115,000. The company has 30 days to respond.
