Power outage leaves Sky Harbor in the dark

Mishap during routine maintenance sends one to the hospital, sparks 'significant' delays

PHOENIX, Ariz. (KYMA, KECY) - Thousands of travelers are dealing with delays hours after a power outage at Phoenix Sky Harbor International Airport.

Sky Harbor sent out a tweet just after eight Monday morning alerting people to a partial outage affecting terminals serving American and Southwest Airlines.

UPDATE: At approx. 8:05 a.m. @apsFYI notified PHX of a partial power outage affecting systems in both terminals. As of 9 a.m. power has been restored to Terminal 3. There continues to be impacts to Terminal 4. @AmericanAir and @SouthwestAir are having significant flight impacts.

Arizona Public Service (APS) says a crew was performing scheduled maintenance when some equipment failed. The failure not only caused the outage, but injured an APS worker. Paramedics took him to the hospital. His injuries are not life-threatening.

APS had power restored to Terminal 3 by 11:30 a.m., but both American and Southwest suffered "significant flight impacts." Sky Harbor doesn't expect schedules to get on track until early afternoon. You can check the flight schedule here.

Crews are still working on fully restoring systems in Terminal 4. Sky Harbor expects to have everything back on line by 1:30 p.m. MST.
