Light-rail service into and out of Santee will likely resume Friday following completion of repairs to equipment damage caused when a light plane clipped trolley power lines and crashed onto a road at the edge of Gillespie Field.

Trolley service has been suspended in the East County city since shortly after 10:30 a.m. Wednesday, when the single-engine Czech Aircraft Works Sportcruiser plummeted onto Cuyamaca Street, near Weld Boulevard, dragging down about 150 feet of electrical lines powering the commuter trams.

The rental aircraft came to rest upside down, trapping the 79-year-old pilot and sole occupant. It took emergency crews roughly 30 minutes to free the Del Mar man, who was hospitalized for treatment of non-life-threatening arm injuries.

Officials with Metropolitan Transit System hope to resume trolley service between El Cajon and Santee early Friday morning, MTS spokeswoman Natalie Wardel said.

In the event of further delays in resuming the light-rail runs, the agency will continue offering bus rides to affected customers, according to Wardel.
