CALIFORNIA BRIEFING / SAN DIEGO COUNTY

Three people were injured, two seriously, when a single-engine plane they were in crashed Saturday evening at Camp Pendleton Marine Corps Base, authorities said.

The Cessna 172 was headed to Montgomery Field in San Diego when it went down on the west side of Interstate 5 near Las Pulgas Road at 5:50 p.m., said Ian Gregor, spokesman for the Federal Aviation Administration.

The plane was registered to Alan Jacobson of Costa Mesa, according to FAA records. One of the injured was airlifted to Scripps Memorial Hospital, and the other two were taken to Mission Hospital in Mission Viejo, Gregor said, adding that an FAA investigator was on the scene Saturday night.

The plane was the same type that crashed Friday about 35 miles off Oceanside.

On Saturday, the U.S. Coast Guard suspended its search for survivors of that crash. The Coast Guard identified the pilot in that incident as Stone Froberg, 71, of San Diego, and said it was “very likely” that Froberg was the only person aboard. The FAA and police are continuing their investigation into whether others were on the plane.

Boaters on the vessel Good Samaritan reported seeing Froberg’s plane, which had been rented from Golden Wings Flying Club at Montgomery Field.

“It’s sheer coincidence, it really is,” said Timm Tesch, president of Golden Wings. That model Cessna is very safe and “designed for training,” Tesch said.
