Damage is estimated at $250,000 from an April 30 fire in the Sea-Tac Airport parking garage. The fire destroyed eight cars and damaged another 10.

Cause of the fire is believed to be mechanical failure in one of the vehicles. Airport staffers will attempt to identify owners through license plate numbers and notify them before they return to the airport.

Smoke from the fire closed one service tunnel and doors were closed in the north end but airport operations remained normal.

The Port of Seattle Fire Department first responded at 7 a.m. on April 30 to the fire on the garage’s sixth floor. Firefighters from the SeaTac Fire Department and other jurisdictions also responded.
