An underground cable failure at Mitchel Field caused more than 2,300 Long Island Power Authority customers in Uniondale to lose power for almost a half hour Monday, a company spokesman said.

Then, while repair crews were attempting to restore power, a primary feeder cable on Front Street came down - causing minor delays to restoring all customers, LIPA spokesman Mark Gross said.

The incident first began at about 9:50 a.m.

Gross said all but 27 of the 2,369 affected customers had power restored within 28 minutes. The other customers had their power restored within the next half-hour - a total delay of 58 minutes, Gross said.

The cause of the cable failure has not yet been determined and remains under investigation, Gross said.
