LAX91LA365

The acft's takeoff was not observed from the uncontrolled airport, and the acft's owner/pilot did not receive any services from air traffic control during the accident flight. When the pilot's son, who was on board the acft, failed to return home his family became concerned and a search commenced. Three days later his body washed up on a pacific ocean beach, about nine miles south of where the acft had been based and was last observed. Near the body, a wheel and a seat cushion were also found. The time of the acft accident was not determined, no additional wreckage has been located, and the body of the owner/pilot remains missing. Toxicological evidence from the son's body did not indicate the presence of cyanide or carbon monoxide poisoning. The father and son occupants of the acft both possessed expired student pilot certificates. The acft had been maintained on an annual inspection program, and the elt's battery replacement date was current. No ELT signal was received.
