Authorities identified a 79-year-old Orange County man as the pilot who died when a plane crashed into a Riverside residential area, the Riverside County coroner’s office said Tuesday.

Melvyn Caffey died Saturday after a twin-engine Beechcraft BE50 he was piloting crashed on the 10500 block of Robinson Avenue near Norwood Avenue in the La Sierra area at around 11:50 a.m., according to the Riverside police and fire departments.

Shortly before the crash, the pilot made a distress call to the Riverside Municipal Airport tower about engine trouble, fire officials said at the time, adding that there was was very little time between when the call came out and when the plane crash was reported.

Witnesses reported seeing the plane nose-diving into a home’s yard.

Four people were inside the home, but there were no injuries reported, officials said.

The home’s patio, fence and a tree in the yard sustained minor damages in the crash, according to the Riverside Fire Department.

The coroner’s office described Caffey’s home as being in Orange County, without offering any specific city.

No further information was available on what led to the crash.

The Federal Aviation Administration and the National Transportation Safety Board were investigating the incident.
