A light utility helicopter crashed in the vicinity of Mokelumne Hill on Saturday, a representative of the Federal Aviation Administration said Monday.

Allen Kenizter in the FAA Office of Communications said the FAA and the National Transportation Safety Board will investigate the crash.

Kenizter said only a single pilot was reported to be on board the helicopter, which crashed under unknown circumstances.

Local authorities would likely have information related to the pilot’s condition, he said.

Representatives of Cal Fire, Mokelumne Hill Fire Protection District and the Calaveras County Sheriff’s Office could not immediately be reached for comment. 

According to the FAA database, the helicopter is an SE 3130 Alouette II and was manufactured in 1958. The manufacturer is French in origin and cited as SNIAS, or “Société nationale industrielle aérospatiale.” The FAA described the craft as having a turbo-shaft engine manufactured by Turbomeca.

The registered owner is a Mokelumne Hill man with an address on the 9200 block of Highway 26.
