Contra Costa Fire Protection District Rescue Boat 81 returns to shore after participating in the search for the pilot and plane believed to have crashed into the Delta north of Antioch, Sunday, June 9. Debris was found floating in Broad Slough west of Kimball Island, but the main part of the wreckage has not yet been located.

UPDATE: 6-11-19 2:20 P.M. A spokesperson for the Contra Costa County Office of the Sheriff confirmed the body of the pilot who crashed into the Delta Sunday evening was recovered by a dive team Monday night. The pilot has been identified as Colin Um, a 22-year-old resident of Berkeley. According to the Sheriff's Office an autopsy is scheduled. 


UPDATE: 6-10-19 5 P.M. The wreckage of a plane that crashed into the Delta Sunday evening has been located, according to the Office of the Sheriff. The pilot has not been found.

Marine Patrol Deputies, assisted by the U.S. Coast Guard, used a side scan sonar and remotely operated vehicle to find the exact location of the plane. The plane wreckage was located at about 10:30 AM. A Sheriff’s Office Dive Team was later deployed.

The name of the pilot is not being released at this time as his identity has not been confirmed.

The Marine Services Unit is continuing with recovery operations. A salvage company is expected to remove the plane wreckage within the next few days.


The Contra Costa County Office of the Sheriff is continuing their search this morning for the pilot and wreckage from an airplane crash in the Delta on Sunday evening, June 9.

A social media post from the sheriff stated the flight originated from Buchanan Field in Concord at approximately 5 p.m. It was believed the pilot was the only person onboard.

Shortly after 5:30 p.m., a caller reported seeing an airplane go into the water north of Antioch. The Contra Costa Fire Protection District (ConFire) established a command center at the Antioch Marina and multiple agencies initiated a search using boats and air resources. Approximately an hour later, searchers found debris from an airplane, a backpack and aeronautical charts floating in Broad Slough west of Kimball Island.

“We found some floating wreckage and some luggage,” said Steve Hill, ConFire public information officer. “That was at 6:40 p.m. We have not found anything below the surface – only the floating items I mentioned. What we found floating was part of the tail.”

Searchers were able to determine the type of aircraft that crashed by examining the recovered part of the plane’s tail section, and they subsequently determined the origin of the flight.

“A flight plan was filed with the Federal Aviation Administration out of Buchanan, filed at 3 p.m. with one person onboard,” said Hill. “We don’t know who was onboard. We just know that there was the flight plan. We know that it was rented from Sterling Aviation, and we know that it was a Piper Cherokee PA-28.”

The Sterling Aviation website does indicate that a four-seat 1975 Piper Cherokee PA-28 was available for pilot rental.

Command of the incident was turned over to the Sheriff’s Office, and a social media post Sunday night indicated a search using sonar had not yet located wreckage. They also stated they were withholding the name of the pilot until his identity can be confirmed.

The Sheriff’s Office is requesting that any witness to the accident contact the National Transportation Safety Board by email at
