One person was killed when a small plane went down in the Santa Susana Mountains near Porter Ranch Saturday afternoon, fire officials said.

The wreckage was discovered about 2:40 p.m. in remote terrain of the Santa Susana Mountains, approximately 2 miles north of Porter Ranch, according to the Los Angeles Fire Department.

But it was not clear exactly when the single-engine, two-seat Nanchang CJ-6 crashed, Federal Aviation Administration spokesman Allen Kenitzer said.

“The aircraft was the subject of an earlier search,” he said.

The aircraft, a Chinese-made military trainer aircraft designed in 1958, crashed into a canyon under unknown circumstances, officials said. There was no fire associated with the crash.

The Fire Department dispatched a rescue helicopter to the scene, where a firefighter lowered to the crash site found the pilot, initially described only asa man, dead, officials said. There were no other people onboard.

No further details were available Saturday afternoon.

It was the second small plane crash in the metro area Saturday, after an aircraft made a crash-landing near the Cable Airport in Upland, injuring three people on board.

The victim’s identity has not yet been released. The cause of the crash was being investigated by the FAA and the National Transportation Safety Board.
