An American volunteer pilot with Los Medicos Voladores (The Flying Doctors) died in a plane crash in Sinaloa, a state in northwestern Mexico, but three other people survived, state officials said.

The plane went down Saturday morning in Baroten, a community outside the city of El Fuerte.

Army troops cordoned off the crash site and secured the wreckage, officials said.

The small plane had taken off from El Fuerte around 8:40 a.m. and was heading for El Carrizo, Sinaloa Attorney General Marco Antonio Higuera Gomez said.

The aircraft hit some power lines and crashed near Baroten, close to the Fuerte River, Higuera Gomez said.

The 61-year-old pilot, identified as John Slater of Phoenix, Arizona, was killed and the other three people aboard the plane - two women and a man - were injured.

The injured passengers are Liam Guzman, Zulia Powers and Jacy Brown, all from California, Medicos Voladores spokeswoman Sofia Ruiz said.

The non-profit organization ( is made up of U.S. volunteers who provide about 7,000 free medical examinations and surgical procedures annually to people in Mexico and other countries in Latin America. EFE
