California Authorities say a pilot from Phoenix, his wife and daughter were killed when a home-built airplane crashed in a San Diego County nature preserve.

Sheriff's Lt. Scott Amos says the single-engine plane went down Saturday morning within Sycamore Canyon Open Space Preserve near Santee. Medical examiners said the dead included a 65-year-old man, his 53-year-old wife and their 19-year-old daughter.

Federal Aviation Administration spokesman Ian Gregor says the four-seat Lancair IV-P had departed from San Diego's Montgomery Field en route to Deer Valley Airport in Phoenix.

The FAA and the National Transportation Safety Board are investigating.

The Lancair web site says the IV-P is one of a series of aircraft kits that are no longer in production
